RESUMEN
PURPOSE: The purpose of the study was to compare postoperative nausea and vomiting (PONV) between laparoscopic cholecystectomy patients under general anesthesia with isoflurane and remifentanil-isoflurane. DESIGN: An observational study was used. METHODS: This observational study was performed on 102 patients who were candidates for laparoscopic cholecystectomy under anesthesia with isoflurane or remifentanil-isoflurane. The patients were evaluated for PONV in the PACU and 3 and 6 hours after the operation. Data were analyzed with descriptive and analytical statistics. FINDINGS: At the time of recovery, the incidence of nausea and vomiting was less in patients under general anesthesia with isoflurane when compared to general anesthesia with remifentanil-isoflurane (P < .04). Nausea and vomiting was also less in the isoflurane group (2%) versus the remifentanil-isoflurane group (9%) at 3 and 6 hours after surgery, but the difference was not significant. CONCLUSIONS: The incidence of PONV in cholecystectomy laparoscopic patients under combined remifentanil with isoflurane anesthesia was relatively low, and it was a bit less in patients under isoflurane anesthesia alone.
