Randomized Controlled Trial Multicenter Study Clinical Trial
Oral dolasetron mesylate for prevention of postoperative nausea and vomiting: a multicenter, double-blind, placebo-controlled study. The Oral Dolasetron PONV Prevention Study Group.
To examine the safety and effectiveness of a range of single oral doses of dolasetron mesylate for the prevention of postoperative nausea and vomiting. ⋯ Single oral doses of dolasetron, administered 1 to 2 hours before induction of anesthesia, are safe and effective for preventing postoperative nausea and vomiting in this patient sample. Maximal antiemetic response was seen with the 50 mg oral dolasetron dose.

Randomized Controlled Trial Clinical Trial
Altered reactivity to acetylcholine in the pulmonary circulation after cardiopulmonary bypass is part of reperfusion injury.
To investigate whether a time sequence of acetylcholine (ACH) reactivity indicative of endothelial reperfusion injury could be demonstrated in the pulmonary circulation in patients after cardiopulmonary bypass (CPB). ⋯ The maintained reactivity to ACH directly after CPB, followed by no reaction at 1 to 1.5 and 4 hours, was in agreement with experimental findings and indicates endothelial reperfusion injury caused by the period with no blood flow through the pulmonary artery during CPB and subsequent reperfusion.
