Randomized Controlled Trial Multicenter StudyGeneral anesthesia for cesarean delivery and childhood neurodevelopmental and perinatal outcomes: a secondary analysis of a randomized controlled trial.
In 2016, the U.S. Food and Drug Administration expressed concern that neurodevelopment may be negatively affected by anesthesia or sedation exposure in pregnancy or before three years of age. We examined the association between general anesthesia at the time of cesarean delivery and early childhood neurodevelopment. ⋯ General anesthesia for cesarean delivery was not associated with overall neurodevelopmental delay at two years of age, except for greater odds of severe motor delay. Future studies should evaluate this finding, as well as the impact on neurodevelopment of longer or multiple anesthetic exposures across all gestational ages.

Randomized Controlled TrialLow-dose intravenous dexmedetomidine reduces shivering following cesarean delivery: a randomized controlled trial.
Intravenous dexmedetomidine 30 µg reduces shivering after cesarean delivery but can result in sedation and dry mouth. We hypothesized that prophylactic administration of 10 µg of IV dexmedetomidine would reduce the patient-reported severity of shivering after cesarean delivery, without an increased incidence of side effects. ⋯ Prophylactic administration of intravenous dexmedetomidine 10 µg after delivery reduces shivering without notable side effects.

Randomized Controlled TrialThe effect of baricity of intrathecal bupivacaine for elective cesarean delivery on maternal cardiac output: a randomized study.
Hemodynamic instability during spinal anesthesia for cesarean delivery is associated with adverse maternal and fetal outcomes. Plain and hyperbaric bupivacaine are commonly used for cesarean delivery, however, their distinctive pharmacologic properties may affect maternal hemodynamic profiles differently. The aim of this study was to compare hemodynamic profiles using a suprasternal Doppler cardiac output (CO) monitor in healthy term parturients randomized to receive plain or hyperbaric bupivacaine for cesarean delivery. ⋯ Cardiac output changes after plain or hyperbaric bupivacaine were not different in term parturients undergoing spinal anesthesia for cesarean delivery. Further studies comparing block quality and the rate of conversion to general anesthesia are required.

Randomized Controlled TrialPre-operative carbohydrate loading prior to elective caesarean delivery: a randomised controlled trial.
Women undergoing elective caesarean deliveries are fasted for long periods prior to surgery and can become catabolic. The use of pre-operative carbohydrate drinks to optimise patients ahead of major surgery is now well established. However, evidence to support this in women undergoing elective caesarean delivery is limited. ⋯ The results of this study support the introduction of carbohydrate drinks ahead of caesarean delivery to offset the effects of pre-operative fasting. However, the results may not be generalisable to all maternity units due to differences in fasting protocols.

Randomized Controlled TrialA cluster quasi-randomized controlled trial of an interactive, monthly obstetric anesthesiology curriculum: impact on resident satisfaction and knowledge retention.
Increasingly, evidence supports the use of educational paradigms that focus on teacher-learner interaction and learner engagement. We redesigned our monthly obstetric anesthesia resident didactics from a lecture-based curriculum to an interactive format including problem-based learning, case discussion, question/answer sessions, and simulation. We hypothesized that the new curriculum would improve resident satisfaction with the educational experience, satisfaction with the rotation, and knowledge retention. ⋯ Our study failed to demonstrate improvement in resident satisfaction or knowledge retention following implementation of an interactive curriculum on a month-long obstetric anesthesia rotation. Reasons may include misalignment of the intervention with measured study outcomes, lack of sensitivity of the survey tools, and inadequate training of faculty presenters.
