Factors influencing neonatal outcomes in twin pregnancies undergoing cesarean section: a cross-sectional study

SUMMARY OBJECTIVE: This study aimed to evaluate maternal and fetal characteristics and factors affecting fetal outcomes in twin pregnancies delivered by cesarean section. METHODS: This was a cross-sectional study in a tertiary care referral hospital. The primary outcome was to ascertain the effects of independent factors on the 1st and 5th minute APGAR scores, neonatal intensive care unit admissions, the need for mechanical ventilation, and neonatal mortality. RESULTS: A total of 453 pregnant women and 906 newborns were included in the analysis. The final logistic regression model revealed that early gestational weeks and neonates <3rd weight percentile at the time of delivery were the most significant predictors of all poor outcome parameters in at least one of the twins (p<0.05). General anesthesia for cesarean section was associated with 1st minute APGAR<7 and the need for mechanical ventilation, and emergency surgery was correlated with the need for mechanical ventilation (p<0.05) in at least one of the twins. CONCLUSION: General anesthesia, emergency surgery, early gestational weeks, and birth weight <3rd weight percentile were strongly associated with poor neonatal outcomes in at least one of the twins delivered by cesarean section.

Opioid-free general anesthesia and induced recovery from anesthesia in a patient with myotonic dystrophy type-1: a case report / Anestesia geral sem opioide e recuperação induzida da anestesia em paciente com distrofia miotônica tipo-1: relato de caso

Abstract Myotonic dystrophy type-1 (Steinert disease) is an autosomal dominant, progressive multisystem disease in which myotonic crisis can be triggered by several factors including pain, emotional stress, hypothermia, shivering, and mechanical or electrical stimulation. In this report, dexmedetomidine-based general anesthesia, in combination with a thoracic epidural for laparoscopic cholecystectomy in a patient with Steinert disease, is presented. An Aintree intubation catheter with the guidance of a fiberoptic bronchoscope was used for intubation to avoid laryngoscopy. Prolonged anesthetic effects of propofol were reversed, and recovery from anesthesia was accelerated using an intravenous infusion of theophylline.

Resumo A Distrofia Miotônica (DM) tipo-1 (Doença de Steinert) é uma doença multissistêmica progressiva autossômica dominante em que a crise miotônica pode ser desencadeada por vários fatores, incluindo dor, estresse emocional, hipotermia, tremores e estímulo mecânico ou elétrico. O presente relato descreve anestesia geral realizada com dexmedetomidina em combinação com peridural torácica para colecistectomia laparoscópica em paciente com Doença de Steinert. Para evitar laringoscopia, a intubação traqueal foi realizada utilizando cateter de intubação Aintree guiado por broncofibroscopia óptica. Os efeitos anestésicos prolongados do propofol foram revertidos e a recuperação anestésica foi acelerada pelo uso de infusão intravenosa de teofilina.
