A comparative analysis of isopropyl alcohol and ondansetron in the treatment of postoperative nausea and vomiting from the hospital setting to the home.
We compared the efficacy of inhaled isopropyl alcohol (IPA) with ondansetron for the control of postoperative nausea and vomiting (PONV) during a 24-hour period in 100 ASA class I-III women undergoing laparoscopic surgery. Nausea was measured postoperatively using a 0 to 10 verbal numeric rating scale (VNRS). The control group received ondansetron, 4 mg intravenously, and the experimental group inhaled IPA vapors. Breakthrough PONV was treated with 25-mg promethazine suppositories. Demographic and anesthesia characteristics were similar between groups. There was a significant difference between groups in mean +/- SD time to alleviation of PONV symptoms: for a 50% reduction in VNRS scores, 15.00 +/- 10.6 vs. 33.88 +/- 23.2 minutes was required in the experimental vs. the control group (P = .001). A total of 21 subjects (10 control; 11 experimental) reported PONV symptoms following discharge to home. The IPA treatment was successful in alleviating PONV symptoms in the home in 91% of the experimental group. We determined that using IPA after discharge from the postanesthesia care unit is a valuable method to control PONV in the hospital and at home. The results of this study suggest that IPA is much faster than ondansetron for 50% relief of nausea.
