Randomized Controlled Trial Clinical Trial
Dexamethasone prevents postoperative nausea and vomiting more effectively in women with motion sickness.
To evaluate the antiemetic effect of iv dexamethasone for preventing postoperative nausea and vomiting (PONV) in women with and without a history of motion sickness. ⋯ Prophylactic administration of dexamethasone is effective in reducing PONV in patients with and without a history of motion sickness. The results of this study were more favourable in patients with a history of motion sickness, demonstrating a higher effectiveness of dexamethasone for preventing PONV in this subgroup of patients.

To evaluate the sensory distribution, motor block and the clinical efficacy of the infraclavicular block by the coracoid approach. ⋯ Infraclavicular block by the coracoid approach provides an extensive sensory distribution with an excellent tourniquet tolerance. We conclude that this approach provides highly consistent brachial plexus anesthesia for upper extremity surgery.

The difficulties of ambulatory interscalene and intra-articular infusions for rotator cuff surgery: a preliminary report.
Rotator cuff repair may result in severe postoperative pain. We compared a continuous intra-articular infusion to a continuous interscalene block with ropivacaine for patients undergoing outpatient rotator cuff repair. ⋯ This study demonstrates the difficulties of ambulatory interscalene and intra-articular infusion for rotator cuff surgery. The high VAS scores and need for additional medical care suggest that intra-articular administration may not be reasonable for this magnitude of surgery. Further refinement of the perineural local anesthetic infusion is necessary to consistently provide analgesia after ambulatory rotator cuff surgery.

Bronchodilator premedication does not decrease respiratory adverse events in pediatric general anesthesia.
Upper respiratory infections (URI) presage perioperative respiratory complications, but thresholds to cancel surgery vary widely. We hypothesized that autonomically-mediated complications seen during emergence from anesthesia would be predicted by capnometry and reduced with preoperative bronchodilator administration. ⋯ Adverse events were neither predicted nor prevented. In afebrile outpatient ASA I and II children with no lung disease or findings, having non-cavitary, non-airway surgery for under three hours, there was no association between either recent URI or active URI and desaturation, wheeze, cough, stridor, or laryngospasm causing desaturation (all P > 0.05). In this highly selected population of afebrile patients, the results suggest that anesthesiologists may proceed with surgery using specific criteria in the presence of a URI.
