Review Practice GuidelineSociety for Ambulatory Anesthesia consensus statement on perioperative blood glucose management in diabetic patients undergoing ambulatory surgery.
Optimal evidence-based perioperative blood glucose control in patients undergoing ambulatory surgical procedures remains controversial. Therefore, the Society for Ambulatory Anesthesia has developed a consensus statement on perioperative glycemic management in patients undergoing ambulatory surgery. A systematic review of the literature was conducted according the protocol recommended by the Cochrane Collaboration. ⋯ It was revealed that there is insufficient evidence to provide strong recommendations for the posed clinical questions. In the absence of high-quality evidence, recommendations were based on general principles of blood glucose control in diabetics, drug pharmacology, and data from inpatient surgical population, as well as clinical experience and judgment. In addition, areas of further research were also identified.

Randomized Controlled Trial Comparative StudyFive unit bolus oxytocin at cesarean delivery in women at risk of atony: a randomized, double-blind, controlled trial.
I.v. bolus oxytocin is used routinely during cesarean delivery to prevent postpartum hemorrhage. Its adverse hemodynamic effects are well known, resulting in a recent change in dose from 10 IU to 5. Whether a 5 IU bolus has any advantages over infusion alone is unclear. We tested the hypothesis that a 5 IU i.v. bolus of oxytocin before the initiation of a continuous infusion decreases the need for additional uterotonic drugs in the first 24 hours after delivery in women with risk factors for uterine atony undergoing cesarean delivery, compared with infusion alone. ⋯ We found that a 5 IU i.v. bolus of oxytocin added to an infusion did not alter the need for additional uterotonic drugs to prevent or treat postpartum hemorrhage in the first 24 hours in women undergoing cesarean delivery with risk factors for uterine atony, despite causing an initial stronger uterine contraction. Our study was not powered to find a difference in side effects between groups. These results suggest that an oxytocin infusion may be adequate without the need for a bolus, even in high-risk patients.
