Randomized Controlled TrialThe influence of aprotinin and tranexamic acid on platelet function and postoperative blood loss in cardiac surgery.
Antifibrinolytic drugs including aprotinin and tranexamic acid are currently used in cardiac surgery to reduce postoperative bleeding and transfusion requirements, and may have different effects on platelets. We therefore evaluated platelet function after cardiopulmonary bypass (CPB) and cardiac surgery to determine the effect of either aprotinin or tranexamic acid. ⋯ Platelet function measured by whole blood aggregometry is better preserved by aprotinin than tranexamic acid and may be responsible for producing less bleeding within the first 24 h after CPB.

Randomized Controlled Trial Multicenter StudyA randomized, double-blind study to evaluate the efficacy and safety of three different doses of palonosetron versus placebo in preventing postoperative nausea and vomiting over a 72-hour period.
We designed this multicenter, randomized, double-blind study to assess the efficacy and safety of three doses of palonosetron, compared with placebo, on the incidence and severity of postoperative nausea and vomiting (PONV) in inpatients for 72 h after surgery. ⋯ A single 0.075-mg IV dose of palonosetron effectively reduced the severity of nausea and delayed the time to emesis and treatment failure in the inpatient surgical setting; lower doses were not as effective.

Randomized Controlled Trial Multicenter StudyA randomized, double-blind study to evaluate the efficacy and safety of three different doses of palonosetron versus placebo for preventing postoperative nausea and vomiting.
In this randomized, double-blind study we assessed the efficacy and safety of three different doses of the 5-HT(3) receptor antagonist palonosetron, compared with placebo, on the incidence and severity of postoperative nausea and vomiting (PONV) for 72 h postsurgery. ⋯ A single 0.075-mg IV dose of palonosetron significantly increased the CR rate (no emetic episodes and no rescue medication) from 0 to 24 h, decreased nausea severity and patients experienced significantly less interference in their postoperative function due to PONV.

Randomized Controlled TrialA randomized controlled trial of pudendal nerve block for pain relief after episiotomy.
Pain from episiotomy or perineal tears during childbirth is associated with significant pain in the postpartum period. We performed this randomized, double-blind, controlled trial to investigate the efficacy of nerve stimulator-guided unilateral pudendal nerve block for pain relief after episiotomy. ⋯ This study demonstrates that nerve stimulator-guided unilateral pudendal nerve block with ropivacaine 7.5 mg/mL is associated with decreased pain and need for additional analgesics during the first 48 h postepisiotomy.

Randomized Controlled TrialA dose-ranging study of intraarticular midazolam for pain relief after knee arthroscopy.
A variety of analgesic techniques have been used to manage postoperative pain after arthroscopic knee surgery. Intraarticular midazolam may have an analgesic effect similar to that seen when midazolam is used in a centroneuraxial fashion. ⋯ We conclude that when intraarticular midazolam was compared with placebo there was a reduction in pain after day-case arthroscopic knee surgery; however, this pain relief was of relatively short duration.
