To investigate whether patients with postural orthostatic tachycardia syndrome (POTS) developed unexpected perioperative complications. ⋯ Intraoperative hypotension, but not tachycardia, was observed in three of 13 patients with POTS who received general anesthesia for a variety of surgical procedures using multiple medications and techniques.

Randomized Controlled Trial
Supplementation of retrobulbar block with clonidine in vitreoretinal surgery: effect on postoperative pain.
To evaluate the effect of clonidine when added to local anesthetics on duration of postoperative analgesia during retrobulbar block. ⋯ The addition of clonidine 0.5 μg/kg to the local anesthetics of a retrobulbar block for vitreoretinal surgery decreases the frequency of postoperative pain and prolongs the time of analgesia.

von Willebrand disease (VWD) is the most common hereditary bleeding disorder in humans, with an estimated prevalence of 0.5% to 1%. Patients with VWD are at increased risk of perioperative bleeding complications. This review provides an evidence-based overview of VWD and its management during the perioperative period.

Randomized Controlled Trial
Prophylactic glycopyrrolate prevents bradycardia after spinal anesthesia for Cesarean section: a randomized, double-blinded, placebo-controlled prospective trial with heart rate variability correlation.
To determine if prophylactic glycopyrrolate prevents bradycardia after spinal anesthesia. ⋯ Bradycardia after spinal anesthesia occurs commonly. Prophylactic glycopyrrolate may prevent the bradycardia, but not necessarily the hypotension.

To determine whether the timely correction of endotracheal tube (ETT) positioning prevents further inappropriate positions. ⋯ Early detection and prompt correction of inappropriate ETT positioning after intubation prevented further ETT migration into undesired positions.
