Supplemental oxygen and 24 hour postoperative nausea and vomiting

Supplemental oxygen reduces the incidence of postoperative nausea and vomiting.

BACKGROUND Despite new anesthetic drugs and antiemetics, particularly 5-hydroxytryptamines, the incidence of postoperative nausea or vomiting remains between 20% and 70%. The authors tested the hypothesis that supplemental perioperative oxygen administration reduces the incidence of postoperative nausea or vomiting. METHODS Patients undergoing colon resection were anesthetized with fentanyl a...

Postoperative nausea and vomiting

Postoperative nausea and vomiting (PONV) is a long-standing issue, not a new concept in anesthesiology. Despite many studies over the last several decades, PONV remains a significant problem due to its complex mechanism. This review presents a summary of the mechanism underlying the pathogenesis of PONV, focusing on preventive treatment, particularly the use of new drugs. In addition, we discus...

Supplemental oxygen does not reduce postoperative nausea and vomiting after thyroidectomy.

BACKGROUND Supplemental intra-operative oxygen 80% halves the incidence of nausea and vomiting after open and laparoscopic abdominal surgery, perhaps by ameliorating intestinal ischaemia associated with abdominal surgery. It is unlikely that thyroid surgery compromises intestinal perfusion. We therefore tested the hypothesis that supplemental perioperative oxygen does not reduce the risk of pos...

Postoperative Nausea and Vomiting

Does supplemental oxygen reduce postoperative nausea and vomiting? A meta-analysis of randomized controlled trials.

BACKGROUND Studies on the ability of supplemental oxygen to decrease the incidence of postoperative nausea and vomiting (PONV) are inconsistent, with initial studies suggesting benefit while subsequent trials demonstrate no decrease in PONV. METHODS To clarify whether supplemental oxygen is an effective and reliable method to reduce PONV, we performed a systematic review (MEDLINE, Cochrane Li...
