Incidence, Timing, and Factors Associated with Postoperative Nausea and Vomiting in the Ambulatory Surgery Setting.

Abstract

PURPOSE:

To examine incidence, timing, and factors associated with postoperative nausea and vomiting (PONV) in patients recovering in the ambulatory postanesthesia care unit (PACU).

DESIGN:

Descriptive correlational, cross-sectional.

METHODS:

Data were collected prospectively, including patient, surgery, anesthesia, and postoperative factors associated with PONV. Independent predictors of nausea were determined using logistic regression.

FINDINGS:

In 139 randomly selected patients, 10.8% had nausea and 2.9% vomited. On arrival to the PACU, 3 patients had nausea, which increased incrementally to 10 during the next 90 minutes, declining to 3 by 150 minutes. These patients had significantly more hydration and longer PACU stays. Fifty-three percent had nausea at discharge. Younger age and gastroesophageal reflux disease were significantly and independently associated with nausea.

CONCLUSIONS:

PONV is relatively infrequent, but remains a distressing problem resulting in negative surgical experiences and increased cost. Future research is warranted to examine gastroesophageal reflux disease as a novel risk factor.
