Observational StudyIncidence of respiratory depression after epidural administration of morphine for cesarean delivery: findings using a continuous respiratory rate monitoring system.
Epidural morphine is widely used for postoperative analgesia after cesarean delivery. However, respiratory depression can occur after neuraxial administration of morphine. Previous reports describing respiratory depression in obstetric patients have relied on intermittent visual counting of the respiratory rate. In this study, we estimated the incidence of respiratory depression in patients who had received epidural morphine after cesarean delivery, using a continuous respiratory rate monitoring system with a finger sensor. ⋯ Approximately half the women experienced mild respiratory depression, but only one developed moderate respiratory depression. Continuous respiratory rate monitoring until ambulation may assist in early identification of respiratory depression after neuraxial administration of morphine.

Massive hemorrhage protocol activation in obstetrics: a 5-year quality performance review.
A structured approach to hemorrhagic emergencies in obstetrics has gained popularity with the implementation of massive hemorrhage protocols. The trauma literature suggests that routine quality reviews should be in place to improve patient outcomes. The aim of this study was to develop quality indicators and assess compliance by the clinical team. ⋯ Suboptimal compliance was found in multiple areas, which may be attributable to the low frequency of activation of our massive haemorrhage protocol in obstetrics. The quality targets identified in this report can act as a basis for other institutions developing quality indicators to evaluate performance.

Case ReportsSyncope after administration of epidural analgesia in an obstetric patient with a vagus nerve stimulator.
Vagus nerve stimulation (VNS) is an adjunctive therapy for medically refractory epilepsy and depression. Vagus nerve stimulation is generally well-tolerated, but cardiac arrhythmias or asystole are rare complications that have been reported. ⋯ These resolved after deactivating the device. This is the first report of a suspected arrhythmia during VNS in the setting of epidural analgesia.
