In-office Laryngeal Procedures: a Modern Perspective for Vocal Fold Interventions

Introduction: The purpose of this article is to discuss in-office laryngeal procedures as an alternative to surgical intervention under general anesthesia. In-office procedures have become more common due to technological advancements. As a result, these approaches are less invasive and more patient-friendly, with increased pain tolerance and reduced procedure time and cost. Methods: We conducted a thematic analysis of published reports regarding the best known and performed in-office laryngeal interventions. Three questions guided our analysis: What laryngological procedures can be performed in the office setting? What are the advantages of in-office laryngology procedures compared to operating room surgical procedures? Why aren't more in-office procedures performed in some Latin American countries? Discussion: Despite being performed more frequently, there is still controversy whether in-office procedures should be performed as often due to the risk of complications. Furthermore, procedures that are done in the office setting are more popular in some countries than in others, even though their benefit has been well demonstrated. This article describes various in-office procedures, including biopsy, vocal fold injections, and laser surgery. We also discuss what factors might contribute to having office-procedures being performed more frequently in some countries than others. Conclusion: Awake interventions offer numerous benefits, including shorter procedure time, reduced costs, and lower patient morbidity. These advantages have significantly transformed the treatment of laryngeal diseases in modern laryngology practice in a global manner.

Introducción: El propósito de este artículo es discutir los procedimientos laríngeos en el consultorio como una alternativa a la intervención quirúrgica bajo anestesia general. Los procedimientos en consultorio se han vuelto más comunes debido a los avances tecnológicos. Como resultado, estos enfoques son menos invasivos y más amigables para el paciente, con mayor tolerancia al dolor y reducción del tiempo y costo del procedimiento. Métodos: Realizamos un análisis temático de los informes publicados sobre las intervenciones laríngeas más conocidas y realizadas. Tres preguntas guiaron nuestro análisis: ¿Qué procedimientos laringológicos se pueden realizar en el consultorio y cuales sin los más frecuentes?, ¿cuáles son las ventajas de los procedimientos laringológicos fuera del quirófano frente a los que se realizan bajo anestesia general?, ¿por qué no se realizan más procedimientos laringológicos en el consultorio en la mayoría de los países en Latinoamérica? Discusión: A pesar de que se realizan con mayor frecuencia, aún existe controversia sobre si los procedimientos en consultorio deben realizarse con tanta frecuencia debido al riesgo de complicaciones. Además, los procedimientos que se realizan en el consultorio son más populares en algunos países que en otros, aunque sus beneficios han sido bien demostrados. Este artículo describe varios procedimientos en el consultorio, incluida la biopsia, las inyecciones de cuerdas vocales y la cirugía con láser. También se discutieron los factores que podrían contribuir a que los procedimientos en el consultorio se realicen con más frecuencia en algunos países que en otros. Conclusión: Las intervenciones con pacientes despiertos ofrecen numerosos beneficios, incluido un tiempo de procedimiento más corto, costos reducidos y una menor morbilidad para el paciente. Estas ventajas han transformado significativamente el tratamiento de las enfermedades laríngeas en la práctica de la laringología moderna a nivel mundial.

Efectividad de la anestesia subaracnoidea con morfina como tratamiento del dolor postoperatorio en cesárea

Fundamento el dolor postoperatorio se considera un dolor con limitaciones de tiempo, a menudo mal controlado. Su manejo representa un gran desafío, ya que la analgesia postoperatoria debe brindar a la madre un control adecuado de este, y a su vez facilitar la atención del bebé. Objetivo evaluar la efectividad de la anestesia subaracnoidea con morfina como tratamiento del dolor postoperatorio en cesárea. Métodos estudio descriptivo y transversal, realizado en el Hospital General Docente Martín Chang Puga, del municipio de Nuevitas, provincia de Camagüey, entre enero de 2021 y diciembre de 2022. La muestra estuvo conformada por 36 pacientes a las cuales se aplicó anestesia subaracnoidea con lidocaína hiperbárica más morfina para la cesárea. Resultados predominó la edad comprendida entre 27-31 años. El 63,9 % de las cesareadas no refirió dolor postoperatorio. Casi la mitad de la población (47,2 %) estudiada presentó efectos secundarios con el uso de la morfina intratecal, principalmente el prurito. El 80,5 % expresó satisfacción con la analgesia postoperatoria. Conclusiones la mayoría de las pacientes encontraron satisfacción con el tratamiento analgésico, a pesar la presencia de efectos adversos, de modo que el uso de morfina intratecal es efectivo en el manejo del dolor poscesárea.

Foundation Postoperative pain is considered time-limited pain, often poorly controlled. Its management represents a great challenge, since postoperative analgesia must provide the mother with adequate control, and at the same time facilitate care for the baby. Objective to evaluate the effectiveness of subarachnoid anesthesia with morphine as a treatment for postoperative pain in cesarean section. Methods descriptive and cross-sectional study carried out at the Martín Chang Puga General Teaching Hospital, in the Nuevitas municipality, Camagüey province, between January 2021 and December 2022. 36 patients to whom subarachnoid anesthesia was applied with Hyperbaric lidocaine plus morphine for cesarean section were considered as the sample. Results the age between 27-31 years predominated. 63.9% of cesarean patients did not report postoperative pain. Almost half of the population (47.2%) studied presented side effects with the use of intrathecal morphine, mainly pruritus. 80.5% expressed satisfaction with postoperative analgesia. Conclusions the majority of patients were satisfied with the analgesic treatment, despite the presence of adverse effects, so that the use of intrathecal morphine is effective in the management of post-cesarean section pain.

Metahemoglobinemia congénita. Reporte de caso / Congenital Methemoglobinemia. A Case Report

Resumen La metahemoglobinemia ocasionalmente causa cianosis, particularmente cuando es congénita. Debido a sus vías enzimáticas deficientes y a la disminución de la capacidad de transporte de oxígeno, para los pacientes con metahemoglobinemia congénita es importante evitar la exposición a agentes oxidantes. A continuación, presentamos un paciente pediátrico con metahemoglobinemia congénita no diagnosticada preoperatoriamente que fue sometido a cateterismo con diagnóstico probable de hipertensión pulmonar bajo anestesia general. El paciente pediátrico era un niño de 10 años que presentaba una lectura de oximetría de pulso (SpO2) 92% antes de la inducción de la anestesia. La metahemoglobinemia se sospechó intraoperatoriamente por primera vez debido a un desajuste de la SpO2 de la oximetría de pulso digital y la SaO2 (saturación arterial de oxígeno), y luego se confirmó mediante múltiples longitudes de onda con la CO-oximetría. Se discuten la fisiopatología, etiología, manifestaciones clínicas, consideraciones anestésicas y opciones de tratamiento de la metahemoglobinemia.

Abstract Methemoglobinemia occasionally causes cyanosis particularly in congenital methemoglobinemia. Avoidance of exposure to oxidizing agents is important for patients with congenital methemoglobinemia because of their deficient enzymatic pathways and decreased oxygen-carrying capacity. Here, we present a pediatric patient with preoperatively undiagnosed congenital methemoglobinemia who underwent catheterization with probably diagnosis of pulmonar hypertension under general anesthesia. The pediatric patient was a 10-year-old who displayed a low pulse oximetry reading of 92% prior to induction of anesthesia. Methemoglobinemia was first suspected intraoperatively because of a mismatch of SpO2 of finger pulse oximetry and SaO2 of arterial blood, and was later confirmed by multiplewavelength CO-oximetry. The pathophysiology, etiology, clinical manifestations, anesthetic considerations, and treatment options of methemoglobinemia are discussed.

General anesthesia versus conscious sedation in mechanical thrombectomy for patients with acute ischemic stroke: systematic review and meta-analysis / Anestesia geral versus sedação consciente na trombectomia mecânica para pacientes com AVC isquêmico agudo: revisão sistemática e metanálise

Abstract Background After recently published randomized clinical trials, the choice of the best anesthetic procedure for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is not definite. Objective To compare the efficacy and safety of general anesthesia (GA) versus conscious sedation (CS) in patients with AIS who underwent MT, explicitly focusing on procedural and clinical outcomes and the incidence of adverse events. Methods PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials (RCTs) comparing GA versus CS in patients who underwent MT due to LVO-AIS. Odds ratios (ORs) were calculated for binary outcomes, with 95% confidence intervals (CIs). Random effects models were used for all outcomes. Heterogeneity was assessed with I2 statistics. Results Eight RCTs (1,300 patients) were included, of whom 650 (50%) underwent GA. Recanalization success was significantly higher in the GA group (OR 1.68; 95% CI 1.26-2.24; p < 0.04) than in CS. No significant difference between groups were found for good functional recovery (OR 1.13; IC 95% 0.76-1.67; p = 0.56), incidence of pneumonia (OR 1.23; IC 95% 0.56- 2,69; p = 0.61), three-month mortality (OR 0.99; IC 95% 0.73-1.34; p = 0.95), or cerebral hemorrhage (OR 0.97; IC 95% 0.68-1.38; p = 0.88). Conclusion Despite the increase in recanalization success rates in the GA group, GA and CS show similar rates of good functional recovery, three-month mortality, incidence of pneumonia, and cerebral hemorrhage in patients undergoing MT.

Resumo Antecedentes A trombectomia mecânica (TM) é o padrão de tratamento para pacientes com acidente vascular cerebral isquêmico agudo (AVCI) devido à oclusão de grandes vasos (OGV). No entanto, ainda não está claro qual é o procedimento anestésico mais benéfico para a TM. Objetivo Nosso objetivo foi comparar a eficácia e a segurança da anestesia geral (AG) versus sedação consciente (SC) em pacientes com AVCI submetidos à TM, focando especificamente nos resultados procedimentais e clínicos, bem como na incidência de eventos adversos. Métodos Foram realizadas buscas sistemáticas nas bases PubMed, Embase e Cochrane por ensaios clínicos randomizados (ECRs) comparando AG versus SC em pacientes submetidos à TM devido a AVCI por OGV. Razões de chances (ORs) foram calculadas para desfechos binários, com intervalos de confiança de 95% (ICs). Modelos de efeitos aleatórios foram usados para todos os resultados. A heterogeneidade foi avaliada com estatísticas I2. Resultados Oito ensaios clínicos randomizados (1.300 pacientes) foram incluídos, dos quais 650 (50%) foram submetidos à AG. O sucesso da recanalização foi significativamente maior no grupo AG (OR 1,68; IC 95% 1,26-2,24; p < 0,04) em comparação com SC. No entanto, não houve diferença significativa entre os grupos para recuperação funcional adequada (OR 1,13; IC 95% 0,76-1,67; p = 0,56), incidência de pneumonia (OR 1,23; IC 95% 0,56- 2,69; p = 0,61), mortalidade em três meses (OR 0,99; IC 95% 0,73- 1,34; p = 0,95) ou hemorragia cerebral (OR 0,97; IC 95% 0,68- 1,38; p = 0,88). Conclusão Apesar do aumento significativo nas taxas de sucesso de recanalização no grupo AG, AG e SC mostram taxas semelhantes de recuperação funcional, mortalidade, pneumonia e hemorragia em pacientes com AVCI submetidos à TM.

Neumoencéfalo en la paciente puérpera una complicación de la anestesia peridural

Introducción: La utilidad de las técnicas de anestesia regional se ha mostrado por muchos años, estas son las de elección por los beneficios que aporta, como es el caso de la cesárea, aunque no están exentas de complicaciones, y las neurológicas que son las más temidas por la gravedad del cuadro clínico presentado y los posibles desenlaces. Objetivo: Describir la evolución clínica de la puérpera con diagnóstico de neumoencéfalo después de anestesia neuroaxial peridural. Presentación de caso: Se trata de una paciente puérpera con antecedente de cefalea migrañosa que después de ser sometida a una anestesia peridural, comienza con dolor de cabeza ligero a moderado que en un principio aliviaba con analgésicos, después hace una convulsión tónica clónico generalizada que fue necesaria intubar y trasladar a terapia intensiva. Mediante la tomografía axial computarizada se detecta neumoencéfalo de pequeñas proporciones en región parietal, además, de signos de edema cerebral, el cuadro evoluciona satisfactoriamente, la paciente a las horas es trasladad a sala donde se reencuentra con su bebe y días después es dada de alta sin secuelas. Conclusiones: El neumoencéfalo como complicación de la anestesia peridural en la paciente gestante, generalmente no tienen gran repercusión clínica y desaparece solo en un período no mayor de 72 horas, pero en ocasiones puede presentarse como complicación grave que puede acarrear daño neurológico permanente e incluso la muerte.

Introduction: Regional anesthesia techniques have been used for many years and there are surgeries where they are the ones of choice due to the proven benefits they provide, as is the case with anesthesia forces is a section, which is not free of complications, but the neurological ones are the ones. Most feared, due to the complexity of the situation and the possible outcomes they could entail. Objective: To describe the evolution of a postpartum patient who was diagnosed with Pneumocephalus after epidural anesthesia. Clinical case: Postpartum patient with a history of migraine headache, which after undergoing epidural anesthesia, began with light to moderate headache that was initially relieved with analgesics, then had a generalized tonic-clonic seizure that required intubation and transfer to the intensive therapy. Using computed axial tomography, small Pneumocephalus was detected in the parietal region in addition to signs of cerebral edema. The condition progressed satisfactorily. Within hours, the patient was transferred to the ward where she was reunited with her baby and day slater she was discharged without squeals. Conclusions: Pneumocephalus as a complication of epidural anesthesia in pregnant patients generally does not have great clinical repercussions and disappears only in a period of no more than 72 hours, but sometime sit can occur as a serious complication that can lead to permanent neurological damage and even death, death.

Descorna bilateral em bovino: aspectos anestésicos e cirúrgicos relato de caso / Bilateral dehorning in cattle: anesthetics and surgical aspects / Descorne bilateral en bovinos: aspectos anestésicos y quirúrgicos reporte de caso

Descorna cirúrgica em bovinos é uma prática bastante realizada na medicina veterinária, com indicação principalmente para evitar acidentes com fraturas, trabalhadores e outros animais. O objetivo do presente relato seria ressaltar o uso de analgésicos e sedativos em bovinos submetidos a este procedimento cirúrgico, compartilhar técnica cirúrgica utilizada, informações de monitoramento de sinais vitais no trans cirúrgico e recomendações pré, trans e pós-cirúrgicas, assim como possíveis complicações. Foi atendido um bovino da raça Jersey, fêmea, 1 ano de idade, pesando cerca de 222kg, submetido a descorna bilateral devido ao comportamento agressivo. Contido em tronco de contenção e tranquilizado com acepromazina, recebeu meloxicam e associação de sulfa com trimetropim. Após tricotomia e antissepsia foi realizado bloqueio perineural do ramo cornual do nervo zigomático temporal e bloqueio infiltrativo ao contorno de cada corno com lidocaína sem vasoconstritor. Com os cornos insensíveis, se deu início ao procedimento de descorna cirúrgica pela associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber. Concluímos ser de extrema importância a execução da técnica cirúrgica por médico veterinário apto, realizando o procedimento de forma asséptica e com analgesia visando o bem estar do animal. No caso em questão, a associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber foi parcialmente satisfatória, o animal apresentou boa margem de fechamento da sutura e sem deiscência dos pontos, porém houve dificuldades de retirada de margens ósseas pontiagudas após uso do alicate. A tranquilização associada ao bloqueio local foi efetiva para tal procedimento.(AU)

Surgical dehorning in cattle is widely performed practice in veterinary medicine, primarily indicated to prevent accidents involving workers, fights between animals, and skull fractures. This procedure involves the removal of the horns of the horns of cattle and should be performed using ethical methods by a qualified veterinarian. The objective of this case report is to highlight the use of analgesics and sedatives in cattle undergoing this surgical procedure, share the surgical technique employed, information on vital sign monitoring during the procedure, and pre-, intra-, and post-surgical recommendations, as well as potential complications. A Jersey cattle, female, 1 year old, weighing approximately 222kg, underwent bilateral dehorning due to aggressive behavior. Restrained in a cattle chute and tranquilized with acepromazine, she received meloxicam and a combination of sulfadiazine with trimethoprim. After trichotomy and antiseptic preparation, perineural blockade of cornual branch of the zygomatic temporal nerve was performed, follows by infiltrative blockade around each horn with lidocaine without vasoconstrictor. With the horns desensitized, the surgical dehorning procedure began using a combination of Gigli saw and Dick Kaber-type wire snare. In conclusion, it is of utmost importance for the surgical technique to be performed by a qualified veterinarian, ensuring aseptic procedure and correct analgesia for the well-being of the cattle. In this case, the combination of Gigli saw and Dick Kaber-type wire snare was partially satisfactory; the animal had a good suture closure margin and did not present suture dehiscence, but there were difficulties in we moving pointed bony margins after using the wire snare. Tranquilization combined with local blockade was effective for this procedure.(AU)

El descornado quirúrgico del ganado bovino es una práctica muy utilizada en medicina veterinaria, indicada principalmente para prevenir accidentes que involucren fracturas, trabajadores y otros animales. El objetivo de este informe sería resaltar el uso de analgésicos y sedantes en bovinos sometidos a este procedimiento quirúrgico, compartir la técnica quirúrgica utilizada, información sobre el monitoreo de signos vitales durante la cirugía y recomendaciones pre, trans y posquirúrgicas, así como posibles complicaciones. Se trata de una hembra bovina Jersey, de 1 año de edad, con un peso aproximado de 222 kg, siendo sometida a descornado bilateral por comportamiento agresivo. Se recibieron contenidos en un baúl de contención y tranquilizados con acepromacina, meloxicam y una combinación de sulfas y trimetopim. Mediante tricotomía y antisepsia se realizó bloqueo perineural de la rama cornual del nervio temporal cigomático y bloqueo infiltrativo en todo el contorno de cada miembro con lidocaína sin vasoconstrictor. Con cuerpos insensibles se inició el procedimiento de descornado quirúrgico, combinando técnicas de aserrado con alicates Dick Kaber. Concluimos que es de suma importancia realizar la técnica quirúrgica por un veterinario calificado, realizando el procedimiento de manera aséptica y con analgesia administrada para el bienestar del animal. En el caso que nos ocupa, la asociación de técnicas de la sierra con la pinza tipo Dick Kaber fue parcialmente satisfactoria, el animal presentó un buen margen de cierre de sutura y ninguna dehiscencia de los puntos, sin embargo, hubo dificultades para eliminar los márgenes óseos afilados después de usar alicates La tranquilidad asociada al bloqueo local fue eficaz para este procedimiento.(AU)

Pericapsular Hip Block Guided by Ultrasonography in Elderly People with Hip Fracture in the Emergency Sector: Clinical Trial / Bloqueio pericapsular do quadril guiado por ultrassonografia em idosos com fratura do quadril no setor de emergência: Ensaio clínico

Abstract Objectives This study evaluated pain intensity in elderly subjects with hip fractures admitted to the emergency sector and undergoing preoperative pericapsular nerve group (PENG) block. Additionally, the degree of tolerable hip flexion was assessed. Methods A prospective, randomized, and controlled clinical trial with parallel groups. The control group consisted of elderly subjects with hip fractures undergoing standardized intravenous systemic analgesia. The intervention group consisted of elderly patients with hip fractures undergoing PENG block and standardized systemic analgesia. The groups were evaluated at rest and during movement using the Pain Assessment in Advanced Dementia (PAINAD) scale. We determined pain intensity and reduction, in addition to the degree of tolerable flexion of the fractured hip. All patient assessments occurred before the medication or block administration and at 45 minutes, 12, 24, and 36 hours postmedication or block. Results Preoperatively and 24 hours after PENG block, elderly subjects with hip fracture showed a significant reduction in pain at rest or movement compared to control patients (p< 0.05), with 60% of patients assessed at rest demonstrating desirable pain reduction (≥50%) and only 13.3% of the control group achieving the desired pain reduction. During movement, after undergoing PENG block, 40% of subjects demonstrated the desired pain reduction and no patient from the control group. The intervention group also showed a significant improvement in the tolerable hip flexion group (p< 0.05). Conclusion Preoperative PENG block in elderly subjects with hip fractures admitted to the emergency sector provided a significant reduction in pain compared with the control group.

Aferiram-se intensidade da dor e redução álgica, assim como o grau de flexão tolerável do quadril fraturado. Todos os pacientes foram avaliados previamente à administração de medicação ou bloqueio e aos 45 minutos, 12, 24 e 36 horas pós-medicação ou bloqueio. Resultados No pré-operatório e 24 horas após o PENG block, idosos com fratura do quadril apresentaram redução significativa da dor em repouso ou movimento em comparação com o controle (p< 0,05), com 60% dos pacientes avaliados em repouso, demonstrando a redução álgica desejável de ≥ 50% e apenas 13,3% do grupo controle com redução álgica desejável. Durante o movimento, após o PENG block, 40% demonstraram redução álgica desejada e nenhum paciente do grupo controle apresentou a redução desejada. Verificou-se, também, no grupo intervenção a melhora significativa da flexão tolerável do quadril (p < 0,05). Conclusão O PENG block no pré-operatório de idosos com fratura do quadril, internados no setor de emergência, proporcionou redução significativa da dor em comparação ao grupo controle.

Periarticular Infiltration Compared to Single Femoral Nerve Block in Total Knee Arthroplasty: A Prospective Randomized Study / Infiltração periarticular comparada ao bloqueio do nervo femoral único na artroplastia total de joelho: Um estudo prospectivo randomizado

Abstract Objective To compare patients undergoing total knee arthroplasty (TKA) under spinal anesthesia and single femoral nerve block (FNB) with subjects undergoing TKA under spinal anesthesia and periarticular infiltration (PAI). Materials and Methods A total of 100 patients undergoing primary TKA were randomized into two groups. Group 1 included patients undergoing surgery under FNB associated with spinal anesthesia, while group 2 included patients undergoing TKA under IPA and spinal anesthesia. The assessment of these subjects in the early postoperative period included pain, active flexion, active extension, elevation of the extended limb, and morphine use. Results There was no significant difference in the types of analgesia concerning pain, the elevation of the extended limb, and morphine use. Active flexion and extension were better in the PAI group (p = 0.04 and p = 0.02 respectively). Conclusion We conclude that the techniques are similar regarding pain control, limb elevation, and morphine use. The use of IPA provided better active flexion and extension during the hospital stay compared to single FNB in patients undergoing TKA.

Resumo Objetivo Avaliar pacientes submetidos a artroplastia total do joelho (ATJ) sob raquianestesia e bloqueio do nervo femoral (BNF) único e comparar com pacientes que submetidos a ATJ sob raquianestesia e infiltração periarticular (IPA). Materiais e Métodos Um total de 100 pacientes submetidos a ATJ foram randomizados em dois grupos. O grupo 1 incluiu pacientes submetidos a ATJ sob BNF associado à raquianestesia, ao passo que o grupo 2 incluiu pacientes submetidos a ATJ sob IPA associada à raquianestesia. Os indivíduos foram avaliados no pós-operatório precoce quanto à dor, à flexão e extensão ativas, à elevação do membro estendido e ao uso de morfina. Resultados Não se observou diferença significativa associada ao tipo de analgesia em relação à dor, à elevação do membro em extensão e ao consumo de morfina. Houve melhor flexão e extensão ativas no grupo que recebeu IPA (p = 0,04 e p = 0,02, respectivamente). Conclusão Concluímos que as técnicas utilizadas são semelhantes quanto ao controle da dor, à elevação de membro e ao uso de morfina. O uso de IPA proporcionou uma melhor flexão e extensão ativas durante o período de internação hospitalar comparado ao uso de BNF único em pacientes submetidos a ATJ.

Introducción: la gastrosquisis congénita (GC) es una patología con creciente demanda asistencial. Atentos a esto, en el Centro Hospitalario Pereira Rossell (CHPR) se implementó un protocolo de cuidados llevado adelante por un equipo multidisciplinario. En este trabajo nos proponemos evaluar el impacto en la sobrevida y morbilidad a partir de su aplicación. Material y método: estudio comparativo tipo antes y después de pacientes portadores de GC (n = 47), 29 de una cohorte histórica (GH) y 18 de una cohorte posaplicación de protocolo (GP). Con edad gestacional ≥ 36 semanas y peso al nacer ≥ 2500 g, asistidos en el CHPR entre los años 2016 y 2021. Resultados: no se observaron diferencias perinatales entre ambos grupos, ni en la incidencia de GQ complicadas. En el GP se observó mayor incidencia de cierre abdominal precoz (p < 0,01), menor necesidad de realización de silo quirúrgico (p < 0,01), menor tiempo de administración de ventilación mecánica (p = 0,03), de uso total de opioides (p < 0,01), de administración de nutrición parenteral (p = 0,03), e inicio más temprano de la alimentación enteral (p = 0,03). Sin diferencias en la sobrevida al egreso hospitalario. Conclusiones: la aplicación de un protocolo estandarizado se asoció a una reducción significativa en el tiempo de cierre abdominal, de ventilación mecánica, nutrición parenteral y de opioides, con inicio más precoz de la nutrición enteral.

Introduction: congenital gastroschisis is an increasingly demanded pathology, therefore a care protocol was implemented at the Pereira Rossell Pediatric Hospital (CHPR), and it has been carried out by a multidisciplinary team. In this paper, we aim at assessing the morbidity and mortality impact of survival and morbidity of this application. Materials and Methods: comparative before and after study of a historical cohort (GH, n=29) versus a post-protocol application cohort (GP, n=18), in patients with a gestational age ≥36 weeks and birth weight ≥2500 grams assisted in CHPR between 2016-2021. Results: no perinatal differences were observed between both groups or in the incidence of complicated GQ. In the GP, a higher incidence of early abdominal closure was decreased (GH 3.4% vs GP 67%, p<0.01), less need to perform a surgical silo (GH 100% vs GP 33%, p<0.01 ), shorter mechanical ventilation administration time (GH 2 days vs GP 0.5 days, p=0.03), total use of opioids (GH 3.5 days vs GP 7 days, p<0.01) , of administration of parenteral nutrition (GH 24.5 days vs GP 20 days, p=0.03), and earlier start of enteral feeding (GH 11 days vs GP 7 days, p=0.03). No differences in survival after hospital discharge (93% vs 89%, p=0.63). Conclusions: the application of a standardized protocol was linked to a significant reduction in the time of abdominal closure, mechanical ventilation, parenteral nutrition, and opioids, with earlier initiation of enteral nutrition.

Post-operative nausea and vomiting prophylaxis: A meta-review on systematic reviews and meta-analyses

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and non-pharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

Anesthesia in medical school: A simulation-based curriculum proposal

Introduction Most medical students are not familiar with Anesthesiology, as it is infrequently addressed properly in medical school curricula. However, anesthesiology skills are widely practiced across specialties and commonly performed by general practitioners. Currently, anesthesia curricula are often based on shadowing and lectures without emphasizing relevant skills, behaviors, and attitudes, whereas simulation-based curricula enable a holistic evaluation of the trainee. Objective To implement and assess the perceptions of students and professors of a novel simulation-based anesthesiology curriculum. Methods A descriptive study was planned for evaluating the new proposal. A simulation-based 3-week curriculum was organized using a blended course with skill laboratories. We designed flipped classroom-based lectures (2 weeks) combined with activities using standardized patients, manikins, and hybrid scenarios (1 week). After each activity, feedback was given by an anesthesiologist, as well as individual grading and a survey based on the Kirkpatrick levels. Results From June to November 2020, 53 students were enrolled in the clerkship. Each week, every group of 6-8 students was assigned to the same specialist to perform the activities and track individual progress. The response rate of the survey was 83%. Across the levels of Kirkpatrick, there was an excellent opinion of the activities, as well as a high similarity between the perception of both students and professors. Conclusion Our simulation-based curriculum, which was highly appraised by students and professors, was found to be feasible, appealing, and offered a good introduction to the principles and practices of anesthesiology to medical students.

Introducción: La mayoría de los estudiantes de medicina no están familiarizados con la Anestesiología, ya que la materia pocas veces se aborda adecuadamente en el programa académico de la facultad de medicina. Sin embargo, las habilidades en anestesiología son ampliamente utilizadas por los médicos generales. En la actualidad los currículos de anestesiología suelen basarse en prácticas y conferencias donde no se enfatizan las destrezas pertinentes, las conductas y las actitudes, mientras que los currículos basados en simulación permiten una evaluación integral del aprendiz. Objetivo: Implementar y evaluar las percepciones de estudiantes y de los profesores de un novedoso plan de estudios de anestesiología basado en la simulación. Métodos: Se diseñó un estudio descriptivo para valorar la nueva propuesta. Se organizó un plan de estudios de 3 semanas, basado en simulación, utilizando un curso mixto con habilidades de laboratorio. Diseñamos conferencias basadas en el modelo de aula invertida (2 semanas), combinadas con actividades basadas en pacientes estandarizados, maniquíes y escenarios híbridos (1 semana). Luego de cada actividad, un anestesiólogo ofrecía su retroalimentación, así como calificaciones individuales y una encuesta basada en los niveles de Kirkpatrick. Resultados: Se inscribieron 53 estudiantes en la pasantía de junio a noviembre de 2020. Cada semana se asignaba un grupo de 6-8 estudiantes a un mismo especialista para llevar a cabo las actividades y hacer un seguimiento al progreso alcanzado de manera individual. La tasa de respuesta de la encuesta fue de 83%. En todos los niveles de Kirkpatrick, hubo una excelente opinión sobre las actividades y una elevada similitud en la percepción, tanto de los estudiantes como de los profesores. Conclusión: Nuestro currículo basado en simulación fue muy bien valorado por estudiantes y profesores y se consideró factible, atractivo y que ofrecía a los estudiantes una buena introducción a los principios y prácticas de la anestesiología.

Bloqueo del músculo erector de la espina como rescate analgésico para control de dolor agudo postoperatorio en fractura de escápula: reporte de caso / Erector spinae plane block as an analgesic rescue to acute control postoperative pain in scapula fracture: case report

Resumen: Introducción: el bloqueo en el plano del músculo erector de la espina (ESPB, por sus siglas en inglés) es un procedimiento seguro, en teoría menos exigente que las técnicas convencionales de anestesia regional torácica. Se utiliza para el tratamiento del dolor agudo y crónico. En la revisión de la literatura, no se encontraron informes de su uso como una técnica única en el dolor agudo de fractura de escápula. Presentación de caso: se reporta un caso clínico de ESPB como técnica experimental para el control del dolor postoperatorio agudo en fracturas de la escápula con aplicación a nivel T2. Se llevó a cabo postoperatorio con disminución de dolor después de 10 minutos de realizado, con una calificación de cero en la escala análoga del dolor. En este caso el ESPB fue realizado en el postoperatorio inmediato, con lo que se logró una disminución total del dolor a los 10 minutos, con posterior control de dolor a las 36 horas. Conclusión: este caso muestra la efectividad de ESPB como técnica experimental para control de dolor postoperatorio en fractura de escápula.

Abstract: Introduction: the erector spine plane block (ESPB) is a safe procedure, technically is less demanding than conventional thoracic regional anesthesia techniques. It is used for the treatment of acute and chronic pain. In the literature review, no reports of its use as a single technique in the acute pain of scapula fracture were found. Case presentation: ESPB is reported in a case as an experimental technique for controlling acute postoperative pain in scapula fractures with an application at the T2 level. It was performed postoperatively with a decrease in pain after 10 minutes and a score of zero on the analog pain scale. In this case, the ESPB was performed in the immediate postoperative period, achieving a total decrease in pain at 10 minutes, with subsequent pain control at 36 hours. Conclusion: this case shows the effectiveness of ESPB as an experimental technique for postoperative pain control in scapula fractures.

Use of multimodal anesthesia in the treatment of postoperative pain / Uso da anestesia multimodal no tratamento da dor pós-operatória

ABSTRACT BACKGROUND AND OBJECTIVES: Hippocrates already said 2400 years ago: "relieving pain is a divine work". Postoperative pain is an important symptom, because it affects the patient's recovery and because of the risk of pain chronicity. And as a treatment option, there is multimodal analgesia, mentioned in several studies as the best approach, although opioid therapy is still the main treatment for pain after surgical interventions. The objective of this study was to describe the use of multimodal anesthesia in the treatment of pain, especially in the postoperative period. CONTENTS: A literature review was performed on studies that explained multimodal analgesia, its components, and which analyzed therapeutic drug options. The theme was approached from a consultation of articles published in LILACS, Scielo, Medline and Pubmed, in English and Portuguese, between the years 2012 and 2022. The keywords used for research were: "multimodal analgesia", "multimodal anesthesia", "surgical procedures" "postoperative". In the results, examples of drugs that are part of multimodal analgesia in different procedures were listed. CONCLUSION: In this way, multimodal anesthesia has demonstrated its benefits for the treatment of postoperative pain in various surgical procedures. However, further studies are needed so that this modality can be used more widely.

RESUMO JUSTIFICATIVA E OBJETIVOS: Hipócrates já dizia há 2400 anos: "aliviar a dor é uma obra divina". A dor pós-operatória é um sintoma importante por causar repercussões na recuperação do paciente e devido ao risco de cronicidade da dor. Como opção de tratamento, tem-se a analgesia multimodal, sendo mencionada em diversos estudos como a melhor conduta, embora a terapia com opioides ainda seja o principal tratamento para a dor após intervenções cirúrgicas. O objetivo deste estudo foi descrever o uso da anestesia multimodal no tratamento da dor, em especial no pós-operatório. CONTEÚDO: Foi realizada uma revisão de literatura sobre estudos que explicitaram a analgesia multimodal e seus componentes, ou que analisaram opções terapêuticas de fármacos. O tema foi abordado a partir de uma consulta de artigos publicados nas bases LILACS, Scielo, Medline e Pubmed, na língua inglesa e em português, entre os anos de 2012 e 2022. As palavras-chaves utilizadas para pesquisa foram: "multimodal analgesia", "multimodal anesthesia", "surgical procedures" e "postoperative". Nos resultados, foram listados exemplos de fármacos que fazem parte da analgesia multimodal em diferentes procedimentos. CONCLUSÃO: Nesse sentido, a anestesia multimodal demonstrou seus benefícios para o tratamento da dor no pós-operatório em vários procedimentos cirúrgicos. Contudo, são necessários novos estudos a fim de que esta modalidade seja utilizada de forma mais abrangente.

Application Value of Sevoflurane Combined with Brachial Plexus Block in Children with Humeral Fracture Surgery and its Effect on Hemodynamics: A Clinical and Anatomical Study

SUMMARY: To observe the effect of sevoflurane combined with brachial plexus block (BPB) in children with humeral fracture surgery and its effect on hemodynamics. 84 children who received surgical treatment of humeral fracture in our hospital from September 2019 to September 2022 were selected. According to different anesthesia methods, the children were divided into control group and study group. The control group only received laryngeal mask sevoflurane; the study group received laryngeal mask sevoflurane combined with BPB. The operation situation, hemodynamic indexes, stress level, pain and adverse reactions of children was observed. The postoperative awakening time in the study group was lower than control group, the postoperative pain onset time in the study group was higher than control group (P0.05). Postoperative 2h, the levels of serum cortisol, b-endorpin, norepinephrine and epinephrine in the study group were lower than control group (P0.05). Sevoflurane combined with BPB is helpful to shorten the postoperative awakening time of children with humeral fracture, reduce the degree of postoperative pain, improve hemodynamics, and reduce stress response, and has good safety.

El objetivo fue observar el efecto del sevoflurano combinado con bloqueo del plexo braquial (BPB) en niños con cirugía de fractura de húmero y su efecto sobre la hemodinámica. Se seleccionaron 84 niños que recibieron tratamiento quirúrgico de fractura de húmero en nuestro hospital desde septiembre de 2019 hasta septiembre de 2022. Según diferentes métodos de anestesia, los niños se dividieron en grupo control y grupo de estudio. El grupo control solo recibió sevoflurano en mascarilla laríngea; el grupo de estudio recibió sevoflurano con mascarilla laríngea combinado con BPB. Se observó la situación operatoria, índices hemodinámicos, nivel de estrés, dolor y reacciones adversas de los niños. El tiempo hasta el despertar postoperatorio en el grupo de estudio fue menor que el del grupo control, el tiempo de aparición del dolor postoperatorio en el grupo de estudio fue mayor que el del grupo control (P0,05). A las 2 horas postoperatorias, los niveles séricos de cortisol, β-endorfina, norepinefrina y epinefrina en el grupo de estudio fueron más bajos que los del grupo control (P 0,05). El sevoflurano combinado con BPB es útil para acortar el tiempo de despertar del posoperatorio de los niños con fractura de húmero, reduce el grado de dolor postoperatorio, mejora la hemodinámica y reduce la respuesta al estrés, además de tener buena seguridad.
