BACKGROUND AND OBJECTIVES: Continuous infusion (CI) of remifentanil is common in total intravenous anesthesia. On the other hand, CI of sufentanil for short/medium-term surgeries has not been widely used. The objective of this study was to compare two techniques of total intravenous anesthesia, using CI of remifentanil or sufentanil, regarding their intraoperative behavior and characteristics of recovery of patients undergoing videolaparoscopic surgeries. METHODS: Sixty patients, equally divided in 2 groups (RG and SG), participated in this study. Continuous infusion of remifentanil was used for anesthetic induction in RG, while a bolus of sufentanil associated with CI of this drug was used in SG. The CI of remifentanil was discontinued at the end of the surgery, while the CI of sufentanil was discontinued 20 minutes before the end of the surgery. Patients received ketoprofen and dypirone intraoperatively. Tramadol was used for rescue analgesia in the recovery room. Variations of mean arterial pressure (MAP) and hard reate (HR), time for awakening, propofol consumption, intercurrences in the recovery room, and time of stay in the recovery room were analyzed. RESULTS: Mean MAP was greater in SG than in RG (91.9 × 77.6, p < 0.0001). The incidence of pain was significantly greater in RG than on SG (22 × 1 patient, p < 0.0001). The incidence of postoperative nausea and vomiting (PONV) was greater in RG than in SG (10 × 2 patients, p < 0.0098). The mean time of stay in the recovery room was greater in RG than in SG (76 × 49 min, p < 0.0001). CONCLUSIONS: Hemodynamic control was satisfactory in both groups. Continuous infusion of sufentanil promoted better postoperative pain control with decreased consumption of rescue analgesic and, consequently, reduced incidence of PONV and reduced time of stay in the recovery room.
