Randomized Controlled Trial Comparative StudySurgical conditions with rocuronium versus suxamethonium in cesarean section: a randomized trial.
Onset times and conditions for intubation after rocuronium versus suxamethonium at cesarean section have been evaluated, but no study thus far has examined the influence of these neuromuscular blocking drugs on the surgical conditions or their effect on the duration of surgery and the ease of fetal delivery. We aimed to compare the surgical conditions for delivery in parturients who received deep neuromuscular block with rocuronium with those who had induction with suxamethonium. ⋯ Whereas the induction-to-delivery intervals were comparable, we found rocuronium superior to suxamethonium in allowing better surgical conditions for fetal delivery, which enabled an easier delivery and a shorter incision-to-delivery interval.

Efficacy of the Epidural Positioning Device® in optimizing the acoustic target window for neuraxial needle placement in term pregnancy.
Neuraxial anesthesia can be challenging in obstetric patients due to the gravid uterus interfering with patient positioning. Ultrasound is commonly used in obstetric anesthesia to facilitate neuraxial needle placement. Some positioning maneuvers facilitate the ultrasound visualization of structures and the placement of neuraxial needles, but the Epidural Positioning Device (EPD) has yet to be evaluated. ⋯ Although the application of an EPD did not improve the paramedian acoustic target area in term parturients, greater patient comfort might facilitate needle placement.

Impact of intra-operative dexamethasone after scheduled cesarean delivery: a retrospective study.
Dexamethasone is an effective analgesic and anti-emetic in patients undergoing many surgical procedures but its effects on pain after cesarean delivery are poorly studied. The aim of this study was to evaluate if routine intra-operative administration of dexamethasone improved analgesia and decreased postoperative nausea and vomiting after scheduled cesarean delivery. ⋯ This impact study involving more than 360 patients suggests that routine administration of intra-operative intravenous dexamethasone 4 mg does not provide additional analgesic benefit after scheduled cesarean delivery, in the context of a multimodal postoperative analgesic regimen. Studies are required to determine if a larger dose or repeated administration influence postoperative analgesia or side effects, or whether certain subsets of patients may benefit.
