Postoperative nausea and vomiting in adults: implications for critical care.

Postoperative nausea and vomiting is a dreaded, uncomfortable, and unpleasant patient experience that is also a factor contributing to adverse outcomes in postoperative recovery.

This discussion outlines the wide range of pharmacological and alternative therapies that are available in clinical practice with a case study to illustrate incorporation of these interventions in critically ill patients.
