Orthognathic surgery in a patient with von Willebrand disease: case report

Aim: This study aims to report the perioperative management of a patient with von Willebrand disease (vWd) who underwent orthognathic surgery. The report follows the guidelines of the Case Report Guidelines (CARE) and focuses on the steps taken to prevent bleeding during the surgical procedure. Methods: A 39-year-old female patient with skeletal Class III was treated with maxillary advancement and mandibular setback. Despite normal test results for ristocetin cofactor activity, measures were taken to prevent bleeding, including atraumatic surgical techniques, use of antifibrinolytic medication, induced hypotension during anesthesia, and preparation of blood products for transfusion during trans and postoperative periods if needed. In the end, these measures were not required. Results: The patient did not experience any bleeding during the surgical procedure or postoperative period, demonstrating the effectiveness of the measures taken to manage their blood dyscrasia. Two years after the surgery, the patient had satisfactory aesthetic and functional results and no evidence of relapse. Conclusion: Thus, this case report demonstrates that vWd does not prevent largescale oral and maxillofacial surgeries such as orthognathic surgery as long as proper precautions are taken pre-, intraand postoperatively

Intravenous Use of Tranexamic Acid in Total Knee Arthroplasty with no Tourniquet / O uso endovenoso de ácido tranexâmico na artroplastia total de joelho sem uso de torniquete

Abstract Objective: To identify blood transfusion requirements and postoperative complications in patients undergoing total knee arthroplasty (TKA) with no tourniquet and intraoperative intravenous administration of tranexamic acid. Methods: This retrospective observational study analyzed 49 preopeative and postoperative medical records of patients undergoing TKA. A paired t-test compared changes in hemoglobin (HB) and packed cell volume (PCV), and an independent t-test with Welch correction compared HB and PCV changes between genders. A Spearman correlation test determined associations between age and days of postoperative hospitalization with HB and PCV changes. The significance level adopted was p < 0.05. Results: The patients' mean age was 71.9 ± 6.7 years; most subjects were women (73.5%). The right side (59.2%) was the most affected. Only one participant required a blood transfusion, while three subjects had complications during the postoperative follow-up. No patient had a thromboembolic event. The median length of postoperative hospital stay was 2 days (interquartile range [IQR] = 1.0). There were reductions in HB and PCV levels between the pre-operative and postoperative period, and female patients had a higher HB reduction. Conclusion: TKA with tranexamic acid and no tourniquet did not cause significant postoperative complications or require blood transfusions.

Resumo Objetivo: Identificar a necessidade de transfusão sanguínea e intercorrências inerentes ao pós-operatório de pacientes submetidos à artroplastia total de joelho (ATJ), a partir de manejos realizados sem o uso de torniquete e com administração de ácido tranexâmico endovenoso intra-operatório. Métodos: Trata-se de um estudo observacional retrospectivo, a partir da observação de 49 prontuários médicos de pacientes submetidos à ATJ em pré e pós-operatório. Foi utilizado o teste t pareado para fazer comparações das modificações de hemoglobina (HB) e hematócrito (HT) e o teste t independente com correção de Welch para comparar as modificações de HB e HT entre os sexos. As associações de idade e dias de internação no pós-operatório com as modificações de HB e HT foram testadas pela correlação de Spearman. O nível de significância adotado foi p < 0,05. Resultados: Os pacientes apresentaram idade média de 71,9 ± 6,7 anos. A maioria da amostra foi composta por mulheres (73,5%) e o lado direito (59,2%) foi o mais acometido. Apenas um participante necessitou de transfusão de sangue e três participantes apresentaram intercorrências durante o seguimento pós-operatório. Nenhum paciente apresentou evento tromboembólico. A mediana da duração da internação no pós-operatório foi de dois dias (IIQ= 1,0). Verificaram-se reduções nas dosagens de HB e HT entre o pré e pós-operatório, e pacientes do sexo feminino apresentaram maior redução de HB. Conclusão: ATJ com uso de ácido tranexâmico e sem uso de torniquete não acarretou complicações pós-operatórias ou necessidade de transfusão sanguínea significativas.

Complicações pós-operatórias relacionadas a ressecção do ameloblastoma / Postoperative complications related to ameloblastoma / Complicaciones postoperatorias relacionadas con la resección de ameloblastoma

A ressecção é o tratamento de escolha para tratamento do ameloblastoma, este que é o tumor odontogênico mais comuns, excluindo os odontomas. A desregulação de diversos genes no desenvolvimento de dentes pode desempenhar papel em sua histogênese. Alguns eventos adversos podem ocorrer durante seu tratamento pós-operatório. Recidivas ocorrem porque o ameloblastoma tende a se infiltrar entre o trabeculado ósseo esponjoso intacto na periferia do tumor antes que a reabsorção óssea se torne radiograficamente evidente. Consequentemente, a margem real do tumor sempre se estende além da sua imagem radiográfica ou da margem clínica. Deiscência de sutura é uma complicação que pode ocorrer no pós-operatório imediato na qual as bordas da ferida, que estão unidas por uma sutura, acabam se abrindo, aumentando o risco de infecção e dificultando assim a cicatrização. Fratura de placa de reconstrução é um evento possível de ocorrer em tratamentos de grandes defeitos. O estresse causado pela modelagem da placa durante a conformação da placa, além da ação muscular são uns dos fatores que pode fragilizar o metal da placa. Outras complicações podem ocorrer como: assimetrias, parestesia temporária e permanente do nervo alveolar inferior e deficiência estética e funcional.

Twenty-four hours stay after colorectal surgery: a systematic review

Introduction: The introduction of Enhanced Recovery After Surgery led to increasing twenty-four hours discharge pathways, for example in laparoscopic cholecystectomy and bariatric surgery. However, implementation in colorectal surgery still must set off. This systematic review assesses safety and feasibility of twenty-four hours discharge in colorectal surgery in terms of readmission and complications in current literature. Secondary outcome was identification of factors associated with success of twenty-four hours discharge. Methods: Pubmed and EMBASE databases were searched to identify studies investigating twenty-four hours discharge in colorectal surgery, without restriction of study type. Search strategy included keywords relating to ambulatory management and colorectal surgery. Studies were scored according to MINORS score. Results: Thirteen studies were included in this systematic review, consisting of six prospective and seven retrospective studies. Number of participants of the included prospective studies ranged from 5 to 157. Median success of discharge was 96% in the twenty-four hours discharge group. All prospective studies showed similar readmission and complication rates between twenty-four hours discharge and conventional postoperative management. Factors associated with success of twenty-four hours discharge were low ASA classification, younger age, minimally invasive approach, and relatively shorter operation time. Conclusions: Twenty-four hours discharge in colorectal surgery seems feasible and safe, based on retro- and prospective studies. Careful selection of patients and establishment of a clear and adequate protocol are key items to assure safety and feasibility. Results should be interpreted with caution, due to heterogeneity. To confirm results, an adequately powered prospective randomized study is needed. (AU)

Sintomas vocais, ansiedade e depressão pré e pós-tireoidectomia / Vocal symptoms, anxiety and depression pre and post thyroidectomy / Síntomas vocales, ansiedad y depresión pre y post tiroidectomía

Introdução: Alterações na tireoide e a tireoidectomia podem levar à sintomatologia vocal e emocional.Objetivo: Correlacionar sintomas vocais e traços de ansiedade e depressão pré e pós-tireoidectomia. Métodos: Estudo observacional, longitudinal. Participaram 20 pacientes submetidos à tireoidectomia, ao exame visual laríngeo e à Escala de Sintomas Vocais (ESV) e Escala Hospitalar de Ansiedade e Depressão (HADS) no pré-operatório, pós 1 semana e pós 3 meses, com média de idade de 54,5 anos, maior prevalência do sexo feminino (85%) e tireoidectomia parcial (70%). Resultados: Os pacientes autorreferiram sintomas vocais em todos os momentos, com maior frequência após uma semana e diferença significativa entre o domínio físico pré e pós 1 semana. Na HADS, observou-se maior escore total no pré-operatório e diferença significante nos três momentos, em todos os domínios, com maior diferença entre pré e pós 1 semana. Houve correlação positiva fraca entre os domínios limitação, emocional e escore total da ESV com a subescala de ansiedade pós 1 semana, entre o escore total da ESV e o escore total da HADS e correlação positiva moderada entre os domínios limitação e emocional da ESV com o escore total da HADS após uma semana. Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales. Objetivo: Correlacionar síntomas vocales y rasgos de ansiedad y depresión antes y después de tiroidectomía. Metodos: Estudio observacional/longitudinal. Participaron 20 pacientes que se les realizó tiroidectomía, examen visual laríngeo, Escala de Síntomas Vocales (ESV) y Escala Hospitalaria de Ansiedad y Depresión (HADS) en preoperatorio, 1 semana y 3 meses después, con edad media de 54,5 años, prevalencia del género femenino (85%) y tiroidectomía parcial (70%). Resultados: Los pacientes informaron síntomas vocales en todo momento, con mayor frecuencia después de una semana y una diferencia significativa entre el dominio físico antes y después de 1 semana. En HADS, hubo mayor puntaje total en el preoperatorio y diferencia significativa en los tres momentos, con mayor diferencia entre pre y post 1 semana. Hubo una correlación positiva débil entre limitación, emocional y total de los dominios de la ESV con la subescala de ansiedad después de 1 semana, entre el total de la ESV y e total de la HADS, y una correlación positiva moderada entre la puntuación de limitación y dominios emocionales de la ESV con la puntuación total de HADS después de una semana. Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Cierre primario de la herida operatoria versus cierre diferido en pacientes con peritonitis apendicular generalizada. Ensayo clínico con asignación aleatoria / Primary versus delayed closure of surgical wound in patients with generalized appendicular peritonitis. Randomized controlled trial

Introducción: La infección del sitio operatorio (ISO), es una de las principales complicaciones en la cirugía de la peritonitis generalizada por apendicitis aguda (PGAA). La mejor opción entre cierre primario (CP) y diferido (CD) de la laparotomía, aún es materia de controversia. El objetivo de este estudio fue determinar asociación entre tipo de cierre y desarrollo de ISO en pacientes con PGAA. Material y método: Ensayo clínico con asignación aleatoria (ECA) Se reclutó a pacientes con PGAA sin exclusión de sexo ni edad, e intervenidos quirúrgicamente en el Servicio de Cirugía del Hospital Obrero Nº 1 (La Paz, Bolivia) entre julio de 2019 y noviembre de 2021; y se les asignó de forma aleatoria a CP y CD; con un seguimiento mínimo de 30 días postoperatorio. Se aplicó estadística descriptiva (cálculo de porcentajes, de medidas de tendencia central y de dispersión); y posteriormente, se aplicaron estadísticas analíticas para estudiar asociación entre variables (test exacto de Fisher para variables categóricas y t de student para variables continuas). Se determinaron RA, RR, OR NNT y sus respectivos IC95%. Resultados: Se incluyeron 100 pacientes, divididos en 59 con CP y 41 con CD, con promedio de edad, peso, estatura e IMC de 43±13,1 años, 71±8,5 kilogramos, 1,61±0,8 metros y 27,6±3,2 respectivamente. La ISO fue de 29,8% y 4,7% en los grupos de CP y CD respectivamente. La incidencia de ISO para el CD fue de 0,05 (5%) y de 0,30 (30%) para el CP. Para los seromas, el RA para el CD es de 0,27 y para el CP de 0,55. El Número Necesario a Tratar (NNT) fue 3,97 (IC95%: 2,75-5,19). No hubo mortalidad. Conclusión: El CD se asocia a menor incidencia de ISO.

Introduction: Surgical site infection (SSI) is one of the main complications in surgery for generalized peritonitis due to acute appendicitis (GPAA). The best option between primary (PC) and delayed (CD) laparotomy closure is still a matter of controversy. The objective of this study was to determine the association between the type of closure and the development of SSI in patients with GPAA. Material and method: Randomized Clinical trial. Patients with GPAA were recruited without exclusion of sex or age, and underwent surgery in the Surgery Service of Hospital Obrero No. 1 (La Paz, Bolivia) between July 2019 and November 2021; they were randomly assigned to PC and DC; with a minimum follow-up of 30 days postoperatively. Descriptive statistics were applied (calculation of percentages, measures of central tendency, and dispersion); and subsequently, analytical statistics were applied to study the association between variables (Fisher's exact test for categorical variables and Student's T test for continuous variables). AR, RR, OR, NNT and their respective 95% CI were determined. Results: 100 patients were included, divided into 59 with PC and 41 with CD, with average age, weight, height, and BMI of 43±13.1 years, 71±8.5 kilograms, 1.61±0.8 meters and 27.6±3.2 respectively. The SSI was 29.8% and 4.7% in the PC and DC groups respectively. The incidence of SSI for DC was 0.05 (5%) and 0.30 (30%) for PC. For seromas, the AR for DC is 0.27 and for PC 0.55. The Number Needed to Treat (NNT) was 3.97 (95% CI: 2.75-5.19). There was no mortality. Conclusion: DC is associated with a lower incidence of SSI.

Effect of COVID-19 on Shoulder Arthroplasty at a Tertiary Care Medical Center in New York City / Efeito da COVID-19 na artroplastia de ombro em um centro médico terciário na cidade de Nova York

Abstract Objective The COVID-19 pandemic led to an unprecedented pause in elective surgeries, including shoulder arthroplasty. We sought to determine whether clinical and/or demographic differences would be seen between patients who presented for shoulder arthroplasty during the pandemic compared with the previous year (2019). Methods Institutional records were queried for patients who underwent shoulder replacement between March 1 and July 1 of 2019 and 2020. Demographics, range of motion, surgical duration, hospitalization time, discharge disposition, and postoperative management were analyzed. Results The mean duration of surgery was 160 ± 50 minutes in 2020 and 179 ± 54 minutes in 2019 (p= 0.13). The mean hospitalization time was 36 ± 13 hours in 2020 and 51 ± 40 hours in 2019 (p= 0.04). In 2019, 96% of the patients participated in physical therapy, while 71% did it in 2020 (p= 0.003). A total of 100% of the 2019 patients and 86% of the 2020 patients participated in an in-person postoperative follow-up (p= 0.006). The 2019 patients reported for an office visit on average 14 ± 11 days after surgery; the 2020 patients waited 25 ± 25 days to return for a follow-up (p= 0.10). Range of motion, age, American Society of Anesthesiologists (ASA) scores, and complication rates did not differ between the cohorts. Conclusion Patients presenting for surgery during the initial phase of the pandemic were demographically and clinically similar to 2019 patients. However, the length of stay was significantly reduced during the COVID-19 pandemic. Postoperative follow-up and physical therapy were delayed in 2020, but this did not lead to differences in complication or readmission rates compared with those of the 2019 cohort. Level of EvidenceIII.

Resumo Objetivo A pandemia de COVID-19 causou uma pausa sem precedentes em cirurgias eletivas, inclusive artroplastia de ombro. Procuramos determinar as possíveis diferenças clínicas e/ou demográficas entre os pacientes que realizaram artroplastia de ombro durante a pandemia em comparação com o ano anterior (2019). Métodos Os registros institucionais foram consultados para obtenção de informações sobre pacientes submetidos a artroplastia de ombro entre 1° de março a 1° de julho de 2019 e 2020. Dados demográficos, amplitude de movimento, duração da cirurgia, tempo de hospitalização, condições à alta e manejo pós-operatório foram analisados. Resultados O tempo médio de cirurgia foi de 160 ± 50 minutos em 2020 e de 179 ± 54 minutos em 2019 (p= 0,13). O tempo médio de internação foi de 36 ± 13 horas em 2020 e de 51 ± 40 horas em 2019 (p= 0,04). Em 2019, 96% dos pacientes fizeram fisioterapia, enquanto 71% o fizeram em 2020 (p= 0,003). Todos os pacientes de 2019 e 86% dos pacientes de 2020 participaram do acompanhamento pós-operatório presencial (p= 0,006). Os pacientes de 2019 retornaram para a consulta médica em média 14 ± 11 dias após a cirurgia; os pacientes de 2020 retornaram para o acompanhamento em 25 ± 25 dias (p= 0,10). A amplitude de movimento, a idade, a pontuação da American Society of Anesthesiologists (ASA, na sigla em inglês) e as taxas de complicações não diferiram entre as coortes. Conclusão Os pacientes submetidos a cirurgia na fase inicial da pandemia eram demográfica e clinicamente semelhantes aos pacientes de 2019. No entanto, o tempo de internação diminuiu de forma significativa durante a pandemia de COVID-19. O acompanhamento pós-operatório e a fisioterapia foram adiados em 2020, mas isso não levou a diferenças nas taxas de complicações ou de reinternações em comparação às da coorte de 2019. Nível de EvidênciaIII.

Impact of topical airway anesthesia on immediate postoperative cough/bucking: a systematic review and meta-analysis

Abstract Background Postoperative cough may occur after tracheal intubation, but it is indistinct which drug is best at diminishing these events. Additionally, airway reflexes are commonly accompanied by severe hemodynamics responses during emergence. Objectives To evaluate the role of topical airway anesthesia on immediate post-extubation cough/bucking and extubation time. Methods Randomized clinical trials from MEDLINE, EMBASE, CENTRAL, and LILACS published until December 23, 2020 were included. Our primary outcome was postoperative cough/bucking incidence which was compared between local anesthetics and controls. Extubation times were likewise considered. Predisposition appraisal and subgroup, affectability investigations were likewise performed. Results The pooled analysis found a 45% reduction in cough incidence after treatment with topical airway local anesthetic (RR = 0.55; 95% CI: 0.42 to 0.72; p< 0.001). The number needed to treat (NNT) was 4.61. The intervention showed no differences in reduction of the extubation time (mean difference = -0.07; 95% CI: -0.14 to 0.28; p= 0.49). Conclusion Topical airway anesthesia demonstrated better than placebo or no medication in reducing immediate post-extubation cough/bucking. Further studies could have this objective to combine the different ways to perform better outcomes for patients.

Surgical Safety of Elderly Hospitalized Patients Stratified by Age in General Surgery / 中国医学科学院学报

Objective To compare the surgical safety of elderly hospitalized patients in different age groups undergoing general surgery,and provide references for preoperative evaluation and treatment decision-making.Methods The inpatients ≥ 60 years old in the department of general surgery were selected from a national multi-center survey conducted from January to June in 2015 and from January to June in 2016.The patient characteristics and postoperative outcomes were described,and the risk factors for adverse postoperative outcomes of patients in different age groups were explored.Results The elderly patients (≥75 years old) accounted for 17.33%.The non-elderly patient (< 75 years old) group and the elderly patient (≥75 years old) group had significant differences in the proportions of patients with three or more chronical diseases (13.18% vs.5.36%,P<0.001),emergency surgery (16.64% vs.7.62%,P<0.001),American Society of Anesthesiologists score≥3 (48.68% vs.27.28%,P<0.001),and postoperative return to the intensive care unit(33.64% vs.12.00%,P<0.001).The occurrence of postoperative infectious complications showed no significant difference between the two age groups (7.29% vs.6.40%,P=0.410),while severe complications differed between the two groups (6.51% vs.2.60%,P<0.001).Besides,emergency surgery was a common independent risk factor for the two age groups.Conclusions Advanced age is not a contraindication to surgery of elderly patients.With consideration to patient's physical conditions and available surgical resources,elderly patients can still benefit from surgery.

The efficacy and safety of glucocorticoid stent implantation compared with oral glucocorticoid during perioperative period in chronic rhinosinusitis with nasal polyps / 临床耳鼻咽喉头颈外科杂志

Objective:To compare the perioperative efficacy and safety of postoperative oral glucocorticoid and glucocorticoid stent implantation in patients with chronic rhinosinusitis with nasal polyps（CRSwNP） undergoing functional endoscopic sinus surgery（FESS）. Methods:Sixty patients with bilateral CRSwNP with similar degree of lesions were selected and divided into three groups: conventional surgical treatment group（20 cases）, glucocorticoid stent group（20 cases）, and oral glucocorticoid group（20 cases）. All three groups underwent routine FESS, patients in the sinus glucocorticoid stent group receiving sinus glucocorticoid stent placed in the ethmoid sinuses（one on each side） during surgery, and patients in the oral glucocorticoid group received postoperative oral methylprednisolone at a dose of 0.4 mg/kg per day for 7 days, followed by a tapering of 8 mg per week to 8 mg followed by maintenance therapy for 1 week, for a total of 3-4 weeks. Visual analog scale（VAS） scores were used to evaluate nasal congestion, rhinorrhea, olfaction, and facial pressure symptoms before surgery, as well as at 2, 4, 8, and 12 weeks after surgery. Nasal endoscopic Lund-Kennedy scores were recorded, and adverse reactions such as stent detachment, stent-related allergic reactions, sleep disorders, edema, gastrointestinal symptoms, rash/acne, behavioral/cognitive changes, weight gain, limb pain, and infection risk were documented. Results:The nasal congestion symptom scores at 2, 4, 8, and 12 weeks after surgery were significantly lower than those before operationin all three groups, and the differences were statistically significant（P<0.05）. The sinus glucocorticoid stent group exhibited significantly lower nasal congestion symptom scores at 4 and 8 weeks after surgery compared to the conventional surgical treatment group. The rhinorrhea symptom scores at 2, 8, and 12 weeks after surgery were significantly lower than preoperative scores in all three groups. Additionally, the sinus glucocorticoid stent group had significantly lower rhinorrhea scores than the conventional surgical treatment group at 2 weeks postoperatively. Concerning olfaction, the sinus glucocorticoid stent group showed a significant reduction in scores at 12 weeks postoperatively, while the oral glucocorticoid group exhibited significant improvement starting from 8 weeks after surgery. There were no statistically significant differences in nasal congestion, rhinorrhea, facial pressure, and olfaction scores between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Nasal endoscopy scores revealed lower polyp scores and edema at 2, 4, 8, and 12 weeks postoperatively for all three groups compared to preoperative scores. The conventional surgical treatment group exhibited a significant reduction in nasal secretion scores starting from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups showed significant reductions starting from 2 weeks postoperatively, with scores significantly lower than those of the conventional surgical treatment group at 2 weeks. Scab/scar scores in the conventional surgical treatment group significantly decreased from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups exhibited significant reductions starting from 4 weeks. No statistically significant differences were observed in endoscopy scores（including polyps, edema, nasal secretion, scars, and scabs） between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Regarding adverse reactions, no postoperative complications related to sinus glucocorticoid stent were observed in the sinus glucocorticoid stent group. In the oral glucocorticoid group,1 patient experienced irritability, and 1 patient experienced weight gain. Conclusion:The glucocorticoid stent implantation has comparable effects to oral glucocorticoid in improving postoperative nasal symptoms, reducing nasal mucosal edema, scar formation, and nasal secretion in patients with CRSwNP undergoing FESS, with a better safety profile.

Vivências do luto na amputação em um hospital de urgência e trauma / Experiences of grief and amputation in an emergency and trauma hospital

A definição de amputação compreende a separação total ou parcial de um membro do resto do corpo, com finalidade de proporcionar alívio à dor ou evitar a morte. Apesar de ser algo ocorrido no corpo físico e de cunho reconstrutor, também pode gerar impactos psíquicos a quem vivencia. Objetivos: A presente pesquisa tem como objetivo realizar um estudo qualitativo sobre como as pessoas que sofreram amputação de membros inferiores (MMII) lidam com o processo de mudança corporal e a vivência do luto. O desenvolvimento deste estudo justifica-se pelo avanço no campo da investigação do processo associado à cirurgia de amputação e seus aspectos psicológicos. Isso possibilita uma possível contribuição para a compreensão de como esses sujeitos vivenciam o processo de luto e a reintegração de sua imagem corporal, uma vez que a amputação pode trazer consequências em diversas áreas da vida do paciente. Metodologia: O estudo foi realizado através de uma amostragem intencional, composta por seis participantes, submetidos à amputação de membros inferiores, internados em um hospital de urgências. Para isso foram realizadas duas entrevistas semiestruturadas, utilizadas em dois momentos: após a indicação clínica de amputação e no pós-operatório, após a retirada do membro. Posteriormente, as entrevistas foram analisadas por meio da técnica de análise de conteúdo. Resultados e Discussão: A partir das entrevistas realizadas, emergiram diversos conteúdos emocionais. Assim, compreendeu-se que a amputação, em grande medida, assumiu um caráter traumático para os sujeitos, sobretudo considerando-se as especificidades de cada situação em particular. Conclusões: Mediante o estudo realizado, concluiu-se que o acompanhamento psicológico nesse cenário visa a manejar o impacto psicológico que a perda do membro pode ocasionar na vida do paciente, auxiliando na construção de uma nova imagem corporal, permitindo, assim, que o sujeito possa lidar com as decorrentes repercussões emocionais

The definition of amputation comprises the complete or partial separation of a limb from the rest of the body, with the purpose of providing pain relief or preventing death. Although it is something that happens in the physical body and has a reconstructive nature, it can also generate psychological impacts on those who experience it. Objectives: The objective of this research is to conduct a qualitative study on how individuals who have undergone lower limb amputations cope with the process of bodily changes and the experience of mourning. The development of this study is justified by the advancements in the field of investigation regarding the amputation surgery process and its psychological aspects. This allows for a potential contribution to the understanding of how these individuals experience the mourning process and the reintegration of their body image, as amputation can have consequences in various areas of the patient's life. Methodology: The study was conducted through intentional sampling, consisting of six participants who had undergone lower limb amputations and were hospitalized in an emergency hospital. Two semi-structured interviews were conducted, used at two moments: after the clinical indication of amputation and post-operative limb removal, and later analyzed using content analysis technique. Results and Discussion: Several emotional contents emerged from the interviews conducted. Thus, it was understood that amputation, to a great extent, assumed a traumatic character for these individuals, especially considering the specificities of each particular situation. Conclusions: Based on the conducted study, it was concluded that psychological support in this scenario aims to manage the psychological impact that limb loss can cause in the patient's life, assisting in the construction of a new body image and enabling the individual to cope with the resulting emotional repercussions

Effect of enhanced recovery after surgery on postoperative function and pain in total hip arthroplasty patients with high comorbidity / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effects of enhanced recovery after surgery (ERAS) on postoperative function and pain in total hip arthroplasty (THA) patients with high comorbidity.@*METHODS@#Patients with THA who were admitted between January 2020 and January 2022 were selected as the study objects, and a total of 223 patients with high comorbidity met the selection criteria. Patients were randomly divided into two groups using the random envelope method. During perioperative period, 112 cases in the ERAS group were treated according to the ERAS protocol and 111 cases in the control group with the traditional protocol. There was no significant difference in gender, age, body mass index, Charlson comorbidity index, preoperative diagnosis, the type and number of the comorbidities, preoperative visual analogue scale (VAS) score between the two groups ( P>0.05). However, the Harris score of ERAS group was significantly lower than that of control group before operation ( P<0.05). Preoperative and postoperative hospital stays were recorded. The VAS score was used to evaluate the pain before operation, at 1 day after operation, at the leaving bed time, at the day after discharge, and at 2 weeks after operation. Harris score was used to evaluate hip function before operation and at 2 weeks, 1 month, 3 months, 6 months, and 12 months after operation. The incidence of complications, 30-day readmission rate, mortality rate, and patient's satisfaction were recorded.@*RESULTS@#The length of preoperative hospital stay in ERAS group was significantly shorter than that in control group ( P<0.05). But there was no significant difference in the length of postoperative hospital stay between groups ( P>0.05). All patients in the two groups were followed up 12 months. The VAS score in the two groups after operation was lower than that before operation, and showed a gradually trend with the extension of time, with significant differences between different time points ( P<0.05). VAS scores of ERAS group were significantly lower than those of control group at different time points after operation ( P<0.05). The postoperative Harris scores in both groups were higher than those before operation, and showed a gradually increasing trend with the extension of time, with significant differences between different time points ( P<0.05). Harris scores of ERAS group at 2 weeks, 1 month, and 3 months after operation were significantly higher than those of control group ( P<0.05). Complications occurred in 2 cases (1.79%) of the ERAS group and 6 cases (5.41%) of the control group, with no significant difference in incidence ( P>0.05). In the control group, 1 case was readmitted within 30 days after operation, and 1 case died of severe pneumonia within 1 year of follow-up. There was no readmission or death in ERAS group, and there was no significant difference in the above indexes between the two groups ( P>0.05). At last follow-up, the satisfaction rate of patients in ERAS group was slightly higher than that in control group, but the difference was not significant ( P>0.05).@*CONCLUSION@#For THA patients with high comorbidity, ERAS protocol can shorten preoperative waiting time, better reduce pain, and improve hip function.

A wearable six-minute walk-based system to predict postoperative pulmonary complications after cardiac valve surgery: an exploratory study / 生物医学工程学杂志

In recent years, wearable devices have seen a booming development, and the integration of wearable devices with clinical settings is an important direction in the development of wearable devices. The purpose of this study is to establish a prediction model for postoperative pulmonary complications (PPCs) by continuously monitoring respiratory physiological parameters of cardiac valve surgery patients during the preoperative 6-Minute Walk Test (6MWT) with a wearable device. By enrolling 53 patients with cardiac valve diseases in the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, the grouping was based on the presence or absence of PPCs in the postoperative period. The 6MWT continuous respiratory physiological parameters collected by the SensEcho wearable device were analyzed, and the group differences in respiratory parameters and oxygen saturation parameters were calculated, and a prediction model was constructed. The results showed that continuous monitoring of respiratory physiological parameters in 6MWT using a wearable device had a better predictive trend for PPCs in cardiac valve surgery patients, providing a novel reference model for integrating wearable devices with the clinic.

Factors influencing bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt / 中华肝脏病杂志

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

Cambios fisiopatológicos y complicaciones de las resecciones hepáticas / Physiopathological changes and complications of liver resections / Alterações fisiopatológicas e complicações das ressecções hepáticas

Las modernas técnicas quirúrgicas y anestésicas han permitido ampliar el número de intervenciones quirúrgicas a nivel hepático por diversas patologías. Logrando disminuir su moralidad pero manteniendo al día de hoy elevados niveles de morbilidad. Durante la cirugía hepática se producen cambios hemodinámicos vinculados a la movilización del hígado, a los clampeos y a las pérdidas sanguíneas independientemente de la vía de abordaje. En el postoperatorio las complicaciones o cambios fisiopatológicos derivan de las lesiones producidas por los fenómenos de isquemia y reperfusión; y aquellas producidas por la regeneración hepática. Dicha capacidad depende no solo de la cantidad de hígado remanente sino también de la posible hepatopatía preexistente. La insuficiencia hepática postoperatoria es la complicación más temida y se manifiesta con ictericia, ascitis, encefalopatía y alteraciones en la paraclínica como la hiperbilirrubinemia y descenso del tiempo de protrombina. Las complicaciones quirúrgicas dependen del procedimiento realizado y se dividen principalmente en biliares y vasculares. Las secuelas de las hepatectomías dependen de factores como el estado general del paciente, la presencia hepatopatía, el acto quirúrgico y la cantidad y calidad del hígado remanente.

Modern surgical and anesthetic techniques have made it possible to increase the number of liver surgeries for various pathologies. This has reduced morbidity but still maintains high levels of morbidity. During hepatic surgery, hemodynamic changes related to liver mobilization, clamping and blood loss occur independently of the approach route. In the postoperative period, complications or pathophysiological changes derive from the lesions produced by ischemia and reperfusion phenomena; and those produced by hepatic regeneration. This capacity depends not only on the amount of remaining liver but also on the possible pre-existing hepatopathy. Postoperative liver failure is the most feared complication and manifests with jaundice, ascites, encephalopathy and paraclinical alterations such as hyperbilirubinemia and decreased prothrombin time. Surgical complications depend on the procedure performed and are mainly divided into biliary and vascular. The sequelae of hepatectomies depend on factors such as the patient's general condition, the presence of liver disease, the surgical procedure and the quantity and quality of the remaining liver.

As modernas técnicas cirúrgicas e anestésicas tornaram possível aumentar o número de cirurgias hepáticas para várias patologias. Isto levou a uma diminuição da morbidade, mas ainda mantém altos níveis de morbidade. Durante a cirurgia hepática, ocorrem alterações hemodinâmicas ligadas à mobilização hepática, pinçamento e perda de sangue, independentemente da via de aproximação. No período pós-operatório, complicações ou alterações fisiopatológicas derivam de lesões causadas por fenômenos de isquemia e reperfusão, e aquelas causadas pela regeneração hepática. Esta capacidade depende não apenas da quantidade de fígado restante, mas também de uma possível doença hepática pré-existente. A insuficiência hepática pós-operatória é a complicação mais temida e se manifesta com icterícia, ascite, encefalopatia e alterações paraclínicas, tais como hiperbilirrubinemia e diminuição do tempo de protrombina. As complicações cirúrgicas dependem do procedimento realizado e são divididas principalmente em biliares e vasculares. As seqüelas de hepatectomias dependem de fatores como o estado geral do paciente, a presença de doença hepática, o procedimento cirúrgico e a quantidade e qualidade do fígado restante.

Vitamin d levels and lipid profile in patients undergoing bariatric surgery / Níveis de vitamina d e perfil lipídico em pacientes submetidos à cirurgia bariátrica

ABSTRACT BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.

RESUMO RACIONAL: Deficiências vitamínicas, minerais e metabólicas ocorrem no pós-operatório de cirurgia bariátrica, a curto e longo prazo, sendo intercorrências preocupantes. OBJETIVOS: Avaliar a associação dos níveis séricos de vitamina D com o perfil lipídico, em pacientes obesos submetidos à cirurgia bariátrica. MÉTODOS: Série de casos de pacientes atendidos de 2010 até 2018, em hospital privado de média e alta complexidade, submetidos à cirurgia bariátrica pelas técnicas da gastrectomia vertical e derivação gástrica em Y de Roux, acompanhados pelo mesmo cirurgião. Foram coletados dados sociodemográficos, clínicos, dados laboratoriais e antropométricos no pré-operatório, 6 meses, 12 meses e 24 meses após cirurgia. RESULTADOS: Foram acompanhados 156 indivíduos, maioria sexo feminino (75,6%), comorbidades mais frequentes foram esteatose hepática (76,3%) e hipertensão (48,27). Em relação aos níveis de vitamina D pré-operatórios, apenas 18,9% da população apresentaram níveis satisfatórios (=30 ng/mL). Observou-se redução do peso e melhora do perfil lipídico pós-cirúrgico. Sobre as correlações entre o perfil lipídico e concentração de vitamina D foram observadas correlações significativas apenas na amostra que passou pela técnica cirúrgica derivação gástrica em Y de Roux: correlação negativa entre o colesterol total e vitamina D após 2 anos de cirurgia; correlação positiva entre triglicerídeo e vitamina D 1 ano pós-operatório; e correlação negativa entre HDL e vitamina D 2 anos pós-operatório. CONCLUSÕES: é essencial acompanhar os níveis de vitamina D e perfil lipídico no pré e pós-operatório de forma rotineira a fim de evitar danos relacionados a deficiência dessa vitamina.

Medidas para optimizar cuidados post rinoplastia. Revisión sistemática de la literatura / Measures to optimize rhinoplasty post operative care, systematic review of the literature

Introducción: El cuidado postoperatorio de la rinoplastia ha evolucionado, paralelamente, al desarrollo de la técnica quirúrgica. Existen varias recomendaciones, sin embargo, hay una gran variabilidad interprofesional de las indicaciones post quirúrgicas. Objetivo: Realizar una revisión sistemática de la literatura científica sobre los cuidados post operatorios de la rinoplastia. Material y Método: Para la realización de este estudio se llevaron a cabo búsquedas en PubMed y en Cochrane Database of Systematic Reviews con los perfiles: ([rhinoplasty] AND [post operative care]) y ([rhinoplasty] AND [post surgical care]). Se seleccionaron los artículos publicados en los últimos 10 años, desde 2013 hasta 2023, ambos inclusive. Resultados: Los documentos analizados recogen la evidencia de los diferentes métodos de cuidados post quirúrgicos en rinoplastia. Estos confirman la utilización de corticoides en el período postoperatorio, así como el reposo en 90° y exponen la variabilidad interprofesional que existe en el protocolo postquirúrgico de esta cirugía. Conclusión: El uso de corticoides y el reposo en 90° disminuyen las complicaciones postquirúrgicas de la rinoplastia. Debe existir una clara información sobre lo que el paciente debe esperar post cirugía. El uso de opioides debe ser restringido y la analgesia debe ser multimodal. Es preciso realizar estudios futuros con mayor nivel de evidencia y tener protocolos uniformes para la práctica clínica.

Introduction: The postoperative care of rhinoplasty has evolved along with the development of the surgical technique. There are several recommendations, however there is enormous interprofessional variability of post-surgical indications. Aim: To carry out a systematic review of the scientific literature on rhinoplasty postoperative care. Material and Method: To carry out this study, searches were carried out in PubMed and in the Cochrane Database of Systematic Reviews with the profiles: ([rhinoplasty] AND [post operative care]) and ([rhinoplasty] AND [post surgical care]). Articles published in the last 10 years were selected, from 2013 to 2023, both inclusive. Results: The documents analyzed collect the evidence of the different methods of post-surgical care in rhinoplasty, they confirm the use of corticosteroids in the postoperative period as well as rest at 90° and expose the interprofessional variability that exists in the post-surgical protocol of this surgery. Conclusion: The use of corticosteroids and rest at 90° reduce the post-surgical complications of rhinoplasty. There must be clear information about what the patient should expect post surgery. The use of opioids must be restricted and analgesia must be multimodal. It is necessary to carry out future studies with a higher level of evidence and have uniform protocols for clinical practice.

Effect of intraoperative alveolar recruitment maneuver on intraoperative oxygenation and postoperative pulmonary function tests in patients undergoing robotic-assisted hysterectomy: a single-blind randomized study

Abstract Background Robotic-Assisted Hysterectomies (RAH) require Trendelenburg positioning and pneumoperitoneum, which further accentuate alteration in respiratory mechanics induced by general anesthesia. The role of Recruitment Maneuver (RM) as a lung-protective strategy during intraoperative surgical settings has not been much studied. We planned this study to evaluate the effect of RM on perioperative oxygenation and postoperative spirometry using PaO2/FiO2 and FEV1/FVC, respectively in patients undergoing RAH. Methods Sixty-six ASA I‒II female patients scheduled for elective RAH were randomized into group R (recruitment maneuver, n = 33) or group C (control, n = 33). Portable spirometry was done one day before surgery. Patients were induced with general anesthesia, and mechanical ventilation started with volume control mode, with Tidal Volume (TV) of 6-8 mL.kg−1, Respiratory Rate (RR) of 12 min, inspiratory-expiratory ratio (I: E ratio) of 1:2, FiO2 of 0.4, and Positive End-Expiratory Pressure (PEEP) of 5 cmH2O. Patients in group R received recruitment maneuvers of 30 cmH2O every 30 minutes following tracheal intubation. The primary objectives were comparison of oxygenation and ventilation between two groups intraoperatively and portable spirometry postoperatively. Postoperative pulmonary complications, like desaturation, pulmonary edema, pneumonia, were monitored. Results Patients who received RM had significantly higher PaO2 (mmHg) (203.2+-24.3 vs. 167.8+-27.3, p < 0.001) at T2 (30 min after the pneumoperitoneum). However, there was no significant difference in portable spirometry between the groups in the postoperative period (FVC, 1.40 ± 0.5 L vs. 1.32 ± 0.46 L, p= 0.55). Conclusion This study concluded that intraoperative recruitment did not prevent deterioration of postoperative spirometry values; however, it led to improved oxygenation intraoperatively.
