Lack of Routine Postoperative Labs Not Associated With Complications in Pediatric Perforated Appendicitis.

INTRODUCTION: Postoperative (postop) management of pediatric perforated appendicitis varies significantly, and postop intra-abdominal abscesses (IAA) remain a significant issue. Between 2019 and 2020, our standardized protocol included routine postop labs after an appendectomy for perforated appendicitis. However, given the lack of predictive utility of these routine labs, we discontinued this practice in 2021. We hypothesize that discontinuing routine postop labs will not be associated with an increase in complication rates after an appendectomy for pediatric perforated appendicitis. METHODS: A single-institution, retrospective review of all pediatric appendectomies for perforated appendicitis from January 2019 to December 2021 was conducted at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, Ohio. Data were collected on rate of complications (IAA development, re-admissions, bowel obstructions, superficial surgical site infections, intensive care unit transfers, Clostridium difficile infections, allergic reactions, and transfusions), postop imaging, postop interventions, and length of stay. Statistical analysis was completed using Fisher's exact test and Mann-Whitney U-test. RESULTS: A total of 109 patients (2019-2020 n = 61, 2021 n = 48) were included in the study. All 61 patients from 2019 to 2020 had postop labs compared to only eight patients in 2021. There was no statistically significant difference between the two groups in overall complication rates, but there was a decrease in IAAs reported in 2021 (P = 0.03). There were no statistically significant differences in other complications, postop imaging usage, or postop interventions. The median length of stay was 4.5 d in 2021 compared to 6.0 d in 2019-2020 (P = 0.009). CONCLUSIONS: Discontinuing routine postop labs is not associated with an increase in overall complications rates. Further studies are needed to determine whether routine postop labs can be safely removed in pediatric patients with perforated appendicitis, which would reduce patient discomfort and care costs.

Clinical reasoning for the continuation or discontinuation of hip precautions after total hip arthroplasty in Switzerland: a qualitative study.

BACKGROUND: Growing evidence raises doubts about the need for routine hip precautions after primary total hip replacements to reduce the risk of postoperative dislocation. However, hip precautions are still routinely and widely prescribed in postoperative care in Switzerland. We aimed to investigate experts' clinical reasoning for hip precaution recommendations after total hip arthroplasty. METHODS: Using a convenience sampling strategy, 14 semi-structured expert interviews were conducted with surgeons, physiotherapists, and occupational therapists in the vicinity of an inpatient rehabilitation clinic in Switzerland. Data analysis followed Mayring's principle of inductive and deductive structuring content analysis. RESULTS: Expert statements from the interviews were summarised into four main categories and 10 subcategories. Categories included statements on the incidences of dislocation and underlying risk factors; current preferences and use of hip precautions; their effect on physical function, anxiety, or costs; and patient's adherence to the movement restrictions. Hip surgeons routinely prescribed hip precautions, although in different variations. Fear of dislocation and caution are barriers to changing current practice. Some surgeons are considering individualised prescribing based on patients' risk of dislocation, which therapists would welcome. CONCLUSION: A lack of clear instructions from the surgeon leads to ambiguity among therapists outside the acute hospital. A shared understanding of the need for and nature of hip precautions, guidelines from societies, or at least specific instructions from surgeons to therapists are warranted.

Menor tempo de jejum pré-operatório e alimentação precoce no pós-operatório são seguros? / Lesser time of preoperative fasting and early postoperative feeding are safe?

INTRODUÇÃO: O jejum noturno praticado antes de operações eletivas foi instituído para prevenir complicações pulmonares, vômitos, regurgitação e aspiração do conteúdo gástrico. No ano de 2005 foi desenvolvido o projeto de Aceleração da Recuperação Total Pós-operatória, denominado ACERTO. O projeto é composto por uma equipe multidisciplinar que visa à recuperação do paciente cirúrgico administrando de duas a seis horas antes da operação uma bebida rica em carboidratos (12,5% de dextrinomaltose). A equipe multidisciplinar é composta por anestesistas, cirurgiões, nutricionistas, enfermeiros e fisioterapeutas. OBJETIVO: Frente aos novos métodos de controle no pré-operatório verificar a qual a necessidade de jejum antes de procedimentos cirúrgicos. MÉTODOS: Revisão sobre jejum pré-operatório realizada nos meses de setembro e outubro de 2011, nos sites de busca Scielo e PubMed. Foram selecionados 24 artigos. CONCLUSÃO: Reduzir o tempo de jejum pré-operatório com solução rica em carboidratos até duas horas antes da operação, tal como alimentação precoce no pós-operatório, trazem inúmeros benefícios ao paciente. O projeto ACERTO tem demonstrado bons resultados e estas novas condutas devem ser encorajadas, diminuindo assim o tempo de recuperação do paciente cirúrgico.

INTRODUCTION: Fasting in the night before elective surgery has been established to prevent pulmonary complications, vomiting, regurgitation and aspiration of gastric contents. The year of 2005 was developed the project ACERTO. It consists in a multidisciplinary team that aims to recover the surgical patient by administering two our six hours before surgery, a carbohydrate-rich beverage (12.5% dextrinomaltose). The multidisciplinary team consists of anesthesiologists, surgeons, nutritionists, nurses and physiotherapists. METHODS: Literature review of preoperative fasting conducted during September and October of 2011 in Scielo and PubMed. CONCLUSION: Reducing the time of preoperative fasting with high carbohydrate solution until two hours before the operation as early feeding postoperatively, bring numerous benefits to the patient. The ACERTO project has shown good results and these new behaviors should be encouraged, thereby reducing the recovery time of the surgical patient.

Does administering albumin to postoperative gastroschisis patients improve outcome?

OBJECTIVES: Newborns who undergo surgery for gastroschisis correction may present with oliguria, anasarca, prolonged postoperative ileus, and infection. New postoperative therapeutic procedures were tested with the objective of improving postoperative outcome. PATIENTS AND METHODS: One hundred thirty-six newborns participated in one of two phases. Newborns in the first phase received infusions of large volumes of crystalloid solution and integral enteral formula, and newborns in the second phase received crystalloid solutions in smaller volumes, with albumin solution infusion when necessary and the late introduction of a semi-elemental diet. The studied variables were serum sodium and albumin levels, the need for albumin solution expansion, the occurrence of anasarca, the length of time on parenteral nutrition, the length of time before initiating an enteral diet and reaching a full enteral diet, orotracheal intubation time, length of hospitalization, and survival rates. RESULTS: Serum sodium levels were higher in newborns in the second phase. There was a correlation between low serum sodium levels and orotracheal intubation time; additionally, low serum albumin levels correlated with the length of time before the initiation of an oral diet and the time until a full enteral diet was reached. However, the discharge weights of newborns in the second phase were higher than in the first phase. The other studied variables, including survival rates (83.4 percent and 92.0 percent, respectively), were similar for both phases. CONCLUSIONS: The administration of an albumin solution to newborns in the early postoperative period following gastroschisis repair increased their low serum sodium levels but did not improve the final outcome. The introduction of a semi-elemental diet promoted an increase in body weight at the time of discharge.

Avaliação da ventilação não-invasiva com dois níveis de pressão positiva nas vias aéreas após cirurgia cardíaca / Assessment of noninvasive ventilation with two levels of positive airway pressure in patients after cardiac surgery

INTRODUÇÃO: A aplicação de ventilação por dois níveis de pressão positiva (BiPAP®) associada à fisioterapia respiratória convencional (FRC) no pós-operatório (PO) imediato de cirurgia cardíaca pode contribuir para a diminuição das complicações pulmonares. OBJETIVO: Avaliar a segurança e a adesão da aplicação preventiva do BiPAP® associado a FRC no PO imediato de revascularização do miocárdio. MÉTODOS: Vinte e seis pacientes submetidos a revascularização do miocárdio foram aleatoriamente alocados. O Grupo Controle (GC) foi tratado com FRC, o Grupo BiPAP (GB) foi submetido a 30 minutos de BiPAP®, duas vezes ao dia, associado à FRC. A FRC foi realizada em ambos os grupos, duas vezes ao dia. Todos os pacientes foram avaliados quanto: capacidade vital, permeabilidade das vias aéreas, pressões respiratórias máximas, saturação de oxigênio, frequência cardíaca, frequência respiratória, volume minuto, volume corrente, pressões arteriais sistólica e diastólica. As avaliações foram realizadas durante a internação no pré-operatório, imediatamente após a extubação, e na 24ª e 48ª horas após extubação. RESULTADOS: No GC, 61,5 por cento dos pacientes tiveram algum grau de atelectasias, no GB, 54 por cento (P=0,691). A capacidade vital foi estatisticamente maior no GB no PO (P<0,015). Todos os outros parâmetros de ventilometria, gasometria, manovacuometria e hemodinâmicos foram semelhantes entre os grupos. CONCLUSÃO: A cirurgia de revascularização do miocárdio leva à degradação da função respiratória no PO, e a aplicação da ventilação com pressão positiva (BiPAP®) pode ser benéfica para reestabelecer a função pulmonar mais rapidamente, principalmente a capacidade vital, de forma segura, sendo bem aceita pelos paciente, devido ao maior conforto em relação à sensação de dor durante a execução da fisioterapia respiratória.

INTRODUCTION: The application of two levels of ventilation by positive pressure (BiPAP®) associated with conventional respiratory therapy (CRT) in postoperative periord of cardiac surgery may contribute to reduction of pulmonary complications. OBJECTIVES: To evaluate the safety and compliance of preventive application of BiPAP® CRT associated with immediate postoperative myocardial revascularization. METHODS: 26 patients undergoing coronary artery bypass grafting were randomly allocated in one of the groups. Patients of the Control Group (CG) were treated only with conventional respiratory therapy, compared to BiPAP group (BG) (in addition to conventional respiratory therapy the patients were subjected to 30 minutes of ventilation by two levels twice a day). The conventional respiratory therapy was held in both groups, twice a day. All patients were evaluated for vital capacity, airway permeability, maximal respiratory pressures, oxygen saturation, heart rate, respiratory frequency, Volume Minute, tidal volume, systolic and diastolic blood pressure. Evaluations were performed during hospitalization preoperatively, immediately after extubation, 24h and 48h after extubation. RESULTS: In CG 61.5 percent of patients had some degree of atelectasias, in comparison to 54 percent of BG (P=0.691). The vital capacity was higher in the GB postoperatively (P<0.015). All the other ventilometric, gasometric, hemodynamic and manometric parameters were similar between groups. CONCLUSION: Coronary artery bypass grafting leads to deterioration of respiratory function postoperatively, and the application of positive pressure ventilation (BiPAP®) may be beneficial to restore lung function more quickly, especially vital capacity, safely, and well accepted by patients due to greater comfort with the sensation of pain during the execution of respiratory therapy.

Tratamento endovascular de pseudoaneurisma da aorta abdominal: relato de caso / Endovascular treatment of an abdominal aortic pseudoaneurysm: a case report

Um estudante de 17 anos, masculino, sofreu ferimentos por arma de fogo e foi submetido a uma laparotomia exploradora. No pós-operatório, queixava-se de dores em membros inferiores e de massa abdominal pulsátil. Realizou tomografia computadorizada (TC) de abdome, que evidenciou pseudoaneurisma de aorta abdominal de cerca de 8 cm no maior diâmetro, localizado entre o tronco celíaco e a artéria mesentérica superior. Uma arteriografia confirmou o diagnóstico e procedeu-se, então, a embolização da lesão com fragmentos de fio-guia montados com fios de algodão. Após seis meses, realizou ecoDoppler de aorta abdominal e nova TC de abdome, que evidenciaram fluxo no interior do saco do pseudoaneurisma. Foi, então, submetido a nova embolização endovascular e implante de stent não-revestido de 18 x 58 mm. Após seis meses do último procedimento, realizou-se nova TC de abdome que demonstrou exclusão da lesão.

A 17 years old male student has received several gunshots and was submitted to exploratory laparotomy. After surgery, he complained of pain in the lower limbs and a pulsatile abdominal mass. An abdominal computerized tomography (CT) scan was carried out and revealed an abdominal aorta pseudoaneurysm of about 8 cm in the larger diameter between the celiac trunk and the superior mesenteric artery. An arteriography confirmed the diagnosis and he was submitted to the lesion embolization with cotton suture wires attached to metallic guide wire fragments. After six months, an abdominal aorta Doppler ultrasonography and a new abdominal CT scan were ordered and depicted flow inside the pseudoaneurysm. The patient was then submitted to a new endovascular embolization, and an 18 x 58 mm uncovered stent was placed. After six months from the last procedure, a new abdominal CT scan showed exclusion of the lesion.

Impact of educational intervention on the pattern and incidence of potential drug-drug interactions in Nepal / Impacto de una intervención educativa en el esquema e incidencias de interacciones medicamentosas potenciales en Nepal

Objective: To study the impact of educational intervention on the pattern and incidence of potential drug-drug interactions (DDIs). Method: All patients admitted to Internal Medicine wards of Manipal Teaching Hospital during the study period were included. Patient details were collected using a patient profile form and the datum from the filled forms was analyzed using Micromedex electronic database. An intervention was carried out through a presentation during clinical meeting and personal discussion. The target groups for the intervention included doctors and the nurses. Results: Altogether 435 patients during preintervention and 445 during postintervention were studied. The incidence of potential DDIs was 53% (preintervention) and 41% (postintervention) [chi-square =11.27, p=0.001]. The average number of drugs per patient was 8.53 (pre-intervention) and 7.32 (post-intervention) [t=3.493, p=0.001]. Sixty-four percent of the potential DDIs were of "Moderate" type and 58% had a "Delayed" onset in both the phases. Seventy percent of the potential DDIs during the pre-intervention phase and 61% during post-intervention phase had a "Good" documentation status. Pharmacokinetic mechanism accounted for 45% of the potential DDIs during pre-intervention and 36% in the post-intervention phase. Cardiovascular drugs accounted for 36% of the potential DDIs during pre-intervention and 33.2% during post-intervention phase. Furosemide was the high risk drug responsible for DDIs in both phases. The most common potential DDIs observed were between amlodipine and atenolol (4.82%) (preintervention) and frusemide and aspirin (5.20%) (postintervention). Conclusion: There was an association between potential DDIs and age, sex, and polypharmacy (AU)

La media de medicamentos por paciente fue de 8,53 (pre-intervención) y 7,32 (post-intervención) [t=3,493, p=0,001]. El 64% de las DDI potenciales eran de tipo "Moderadas" y el 58% tenía una iniciación "Retrasada" en ambas fases. El 70% de las DDI potenciales durante la fase de pre-intervención y el 61% en la post-intervención tenían un estado de documentación "Bueno". Mecanismos farmacocinéticos contabilizaron el 45% de las DDI potenciales durante la pre-intervención y el 36 en la post-intervención. Los medicamentos cardiovasculares sumaron el 36% de las DDI potenciales durante la pre-intervención y el 33,2% en la post-intervención. La furosemida fue el de mayor riesgo de DDI en las dos fases. La DDI potencial más comúnmente observada en la pre-intervención fue entre amlodipino y atenolol (4,82%), y en la post-intervención fue entre furosemida y aspirina (5,29%). Conclusión: Existía una asociación entre DDI potencial y edad, sexo y polimedicación (AU)

Degree of risk related to procedures performed in conjunction with surgical myocardial revascularization in octogenarians

INTRODUCTION/OBJECTIVES: We determined the degree of risk produced by the association of other surgical procedures with surgical myocardial revascularization in octogenarian patients and identified the risk factors that best explain hospital mortality. METHODS: This study was an observational analytical historical cohort study involving octogenarians operated on at our institution between January 1, 2000 and January 1, 2005. We stratified the objective population as follows: Group 1 comprised octogenarians revascularized without associated procedures, and Group 2 comprised octogenarians revascularized with associated procedures. Statistical analyses included the t test for independent samples and multiple logistic regression analysis. Significance was accepted with an alpha error of 5 percent. RESULTS: Univariate analyses revealed the following clinical and statistically significant variables: hospital mortality (P=0.002), diabetes mellitus (P=0.017), preoperative endocarditis (P=0.001), cardiogenic shock (P=0.019), use of an intra-aortic balloon pump (P=0.026), preoperative risk score (Parsonnet), P<0.001, procedure associated with revascularization (P<0.001), medium number of affected coronary arteries (P<0.001), use of extracorporeal circulation (P<0.001), time of extracorporeal circulation (P<0.001), number of distal anastomoses (P=0.002), graft type (P<0.001), postoperative breathing support (P<0.001), stroke (P<0.001), infection (P=0.002), creatinine level (P=0.018), and quality of life score (P=0.050). DISCUSSION/CONCLUSIONS: In octogenarian patients, the need for a procedure associated with surgical myocardial revascularization produces an absolute increase in hospital mortality risk of 45 percent. The variables that contributed to hospital mortality were preoperative endocarditis, preoperative cardiogenic shock, the use of extracorporeal circulation, the length of time of extracorporeal circulation, postoperative creatinine level, ...

Náuseas y vómitos postoperatorios: incidencia, características y factores de riesgo. Estudio prospectivo de cohortes / Postoperative nausea and vomiting: Incidence, characteristics and risk factors - A prospective cohort study

Antecedentes. El objetivo de este estudio fue identificar los factores de riesgo y determinar la incidencia de náuseas y vómitos postoperatorios en una cohorte de pacientes en un hospital terciario universitario. Métodos. Estudio de cohortes prospectivo realizado en una Unidad de Recuperación Postanestésica durante un período de 3 semanas. Ciento cincuenta y siete pacientes adultos sometidos a cirugía programada no-cardiaca y no-intracraneal fueron elegibles para el estudio. Fueron analizados datos de los pacientes y de las características perioperatorias. La Escala de intensidad de náuseas y vómitos postoperatorios y la Escala analógica visual de náuseas se aplicaron para medir náuseas y vómitos postoperatorios a las 6 y a las 24h después de la cirugía. Fue efectuado un análisis descriptivo, y para las comparaciones se aplicaron el test de Mann-Whitney, el test exacto de Fisher o el test Chi-cuadrado. Asimismo se aplicó un análisis de regresión logística binaria univariante y multivariante con el cálculo de odds ratio (OR) y su intervalo de confianza del 95% (IC 95%). Resultados. De los 157 pacientes, 39 (25%) tuvieron náuseas y vómitos postoperatorios a las 6h y 54 (34%) a las 24h. Entre los pacientes que experimentaron náuseas y vómitos postoperatorios, en 6 (15%) estos eran clínicamente significativos (Escala de intensidad de náuseas y vómitos postoperatorios>50) a las 6h y en 9 (23%) a las 24h. La mayoría de los pacientes tuvieron náuseas clasificadas como leves a las 6 (57%) y 24 (56%) h. A las 6h, 3 pacientes (10%) tuvieron náuseas clasificadas como severas, y a las 24h, 5 (9%) pacientes. La mediana y el rango intercuartil para la Escala analógica visual de náuseas fue 40 (20-60) a las 6h y 50 (20-60) a las 24h. Seis pacientes (14%) a las 6h y 7 (18%) a las 24h tuvieron una puntuación en la Escala analógica visual de náuseas>75. Los pacientes con un valor>50 en la Escala de intensidad de náuseas y vómitos postoperatorios tuvieron una mayor puntuación en la Escala analógica visual de náuseas a las 6 (75 frente a 30, p<0,05) y 24 (70 frente a 40, p<0,05) h. El análisis univariado identificó los siguientes factores de riesgo para náuseas y vómitos postoperatorios: puntuación Apfel>2 (OR 3,2; IC 95% 1,6-6,4; p=0,001), antecedentes de náuseas y vómitos postoperatorios (OR 2,9; IC 95% 1,3-6,5; p=0,009) y el sexo femenino (OR 2,7; IC 95% 1,4-5,4; p=0,005). En el análisis multivariado fueron factores de riesgo los antecedentes de náuseas y vómitos postoperatorios (OR ajustada 2,5; IC 95% 1,1-5,7; p=0,030) y el sexo femenino (OR ajustada OR 2,4; IC 95% 1,2-4,9; p=0,015). Conclusión. La mayoría de los pacientes no tuvieron náuseas y vómitos postoperatorios clínicamente significativos. Aquellos que presentaron una puntuación>50 en la Escala de intensidad de náuseas y vómitos postoperatorios tuvieron una mayor puntuación en la Escala analógica visual de náuseas. La historia anterior de náuseas y vómitos postoperatorios y el sexo femenino fueran considerados factores de riesgo independientes para náuseas y vómitos postoperatorios (AU)

Background. Postoperative nausea and vomiting are a common complication after surgery. The objective of the study was to identify risk factors, and to determine the incidence of postoperative nausea and vomiting in a cohort of patients in a tertiary university hospital. Methods. Prospective cohort study was conducted in a Post Anesthetic Care Unit during a period of 3 weeks. One hundred and fifty-seven adult patients subjected to scheduled non-cardiac and non-intracranial surgery were eligible for the study. Patient perioperative characteristics data were analyzed. The postoperative nausea and vomiting intensity scale and nausea visual analog scale were applied to measure postoperative nausea and vomiting at 6h and 24h after surgery. Descriptive analysis was performed and the Mann-Whitney U, Fisher's exact, or Chi-square tests were applied. A univariate and multivariate logistic binary regressions with calculation of odds ratio (OR) and its 95% confidence interval (95% CI) were performed. Results. Thirty-nine (25%) patients and 54 (34%) patients had postoperative nausea and vomiting at 6h and 24h, respectively. Of the patients who experienced postoperative nausea and vomiting, 6 (15%) had clinically significant postoperative nausea and vomiting (postoperative nausea and vomiting intensity scale>50) at 6h and 9 (23%) at 24h. The majority of patients classified nausea as mild at 6h (57%) and 24h (56%). At 6h, 3 (10%) patients classified nausea as severe, and at 24h 5 (9%) patients reported the same. The median and interquartile ranges for nausea visual analog scale were 40 (20-60) at 6h and 50 (20-60) at 24h. Six patients (14%) at 6h, and 7 (18%) at 24h had a nausea visual analog scale score >75. Patients with postoperative nausea and vomiting intensity scale > 50 had higher scores in the nausea visual analog scale at 6h (75 versus 30, P<.05) and 24h (70 versus 40, P<.05). The univariate analysis identified risk factors for postoperative nausea and vomiting: Apfel score>2 (OR 3.2, 95% CI 1.6-6.4, P=.001), previous history of postoperative nausea and vomiting (OR 2.9 95% CI 1.3-6.5, P=.009) and female patients (OR 2.7, 95% CI 1.4-5.4, P=.005). In the multivariate analysis previous history of postoperative nausea and vomiting (adjusted OR 2.5, 95% CI 1.1-5.7, P=.030) and female gender (adjusted OR 2.4, 95% CI 1.2-4.9, P=.015) were considered as independent risk factors for postoperative nausea and vomiting. Conclusion. Most of the patients do not have clinically significant postoperative nausea and vomiting. The patients who presented with postoperative nausea and vomiting intensity scale>50 had higher scores in the nausea visual analog scale. Independent risk factors for postoperative nausea and vomiting were previous history of postoperative nausea and vomiting and being female (AU)

Evaluación prospectiva de la seguridad y tolerancia de los procedimientos colonoscópicos en pacientes pediátricos / Prospective evaluation of safety and tolerance of colonoscopy in children

Background: Colonoscopy is a well established diagnostic and therapeutic procedure in pediatrics. Aim: To evaluate colon preparation alternatives for colonoscopy or sigmoidoscopy, type of sedation, clinical indications and findings. Patients and methods: Prospective study of 123 children referred for colonoscopy. Demographic data, type of colon preparation, sedation, type of endoscope and endoscopic results were obtained. The following day, a phone interview was carried out inquiring about duration, quality and adverse effects of the sedation and procedure. Results: Seventy one boys (58%) and 52 girls (42%) with a mean age of 6.7±4.4 years, were recruited. The main indication was lower gastrointestinal bleeding (71%). The different colon preparations produced elimination of clear liquid stools in 50%, non transparent liquid in 23%, semi liquid in 22% and solid in 6% of the patients. Most common side effects were abdominal distension (20%) and nausea (16.8%). The most commonly used drugs were midazolam (76%) and demerol (43%). The average duration of the procedure was 18.3 minutes (range: 4-50). The most common findings were rectal polyps (18.7%) and hemorrhagic colitis (14.6%). In 77% of cases, the sedation was considered very good or good. Colon visualization was described as very good (51%) or good (36%). Seventy three percent of children had complete amnesia. The most common adverse effect was vomiting (7.5%). Conclusion: Lower endoscopies are feasible procedures to carry out in children, in an ambulatory basis, with intravenous sedation and minimum adverse effects.

Processo anestésico-cirúrgico: alterações metabólicas, sistêmicas e imunológicas e complicações / Anesthetic and surgical process: metabolic, systemic and immunologic alterations and complications

O processoa anestésico-cirúrgico implica alterações metabólicas, sistêmicas e imunológicas, resultantes do trauma, que representam estratégias fundamentais do organismo para o restabelecimento do equilíbrio fisiológico. Sendo assim, consideramos que o conhecimento da fisiologia acerca das respostas ao trauma anestésico-cirúrgico, das complicações relaciondas com a interação medicamentosa, da insuficiência renal aguda e da infecção constitui recurso básico para a otimização do cuidado durante o período pós-operatório.

Seleção da artéria radial para utilização como enxerto aortocoronário: avaliação pré-operatória com eco-color-Doppler e fotopletismografia digital e confirmação por avaliação cirúrgica / Selection of radial artery for use as aortocoronary graft: preoperative assessment with Doppler ultrasound and digital photoplethysmography and surgical confirmation

Objetivo: Com o crescente uso da artéria radial como enxerto aortocoronário, torna-se necessário reavaliar os critérios utilizados para a seleção desse vaso no pré-operatório da cirurgia de revascularização miocárdica. O objetivo deste estudo foi utilizar a avaliação do vaso pelo cirurgião cardíaco no perioperatório para confirmação da viabilidade da artéria radial selecionada, por meio de dois métodos não-invasivos (eco-color-Doppler e fotopletismografia digital) no pré-operatório. Métodos: Entre julho de 1998 e maio de 2000, foram estudadas 78 artérias radiais e 78 artérias ulnares de 39 pacientes, candidatos à cirugia de revascularização do miocárdio. O estudo foi realizado bilateralmente através do aparelho de ultra-sonografia ATL HDI 5000...
