Randomized Controlled Trial
Transdermal scopolamine patch in addition to ondansetron for postoperative nausea and vomiting prophylaxis in patients undergoing ambulatory cosmetic surgery.
To determine the efficacy of transdermal scopolamine in addition to ondansetron in decreasing the incidence of postoperative nausea and vomiting (PONV). ⋯ Transdermal scopolamine in addition to ondansetron benefits patients at high risk for PONV undergoing outpatient plastic surgery for up to 20 hours after surgery.

Comparative Study
Anesthesia-controlled time and turnover time for ambulatory upper extremity surgery performed with regional versus general anesthesia.
To test the hypothesis that regional anesthesia (RA) employing a block room reduces anesthesia-controlled time for ambulatory upper extremity surgery compared with general anesthesia (GA). ⋯ Peripheral nerve block performed preoperatively in an induction area or LA injected in the OR significantly reduces anesthesia-controlled time for ambulatory upper extremity surgery compared with GA. Turnover time is unaffected by anesthetic technique. These results may increase acceptance of RA in the ambulatory surgery setting.

Comparative Study
Interscalene block for postoperative analgesia using only ultrasound guidance: the outcome in 200 patients.
To report the results of single and continuous interscalene blocks (ISB) performed using ultrasound (US) guidance only. ⋯ In this group of 200 consecutive patients, the success rate for postoperative analgesia using US guidance only was 99%. Untoward events such as needle paresthesia and persistent neurologic deficits were lower than existing data on nerve stimulation and paresthesia techniques. Ultrasound can be successfully used as a "stand alone" method to perform ISB.
