Declaration of interest. The work was supported by Aventis Pharma, Germany and included payment of patients insurance and the fee of the local ethics committee.
Results of this work have been presented at the German Congress of Anesthesiology in Munich, May 2000 and at the Annual Meeting of the ASA, in San Francisco, October 2000.
Background. Remifentanil is used as an analgesic for different procedures performed during monitored anaesthesia care. Opioid-induced nausea and vomiting can be troublesome.
Methods. This prospective, randomized, double-blind study was performed to evaluate the efficacy of prophylaxis with dolasetron in reducing the frequency of postoperative nausea and duration of discharge time. Forty urological patients, undergoing elective ambulatory extracorporeal shock wave lithotripsy (ESWL) received randomly either dolasetron 12.5 mg i.v. (Group 1) or placebo (Group 2) 10 min before a patient-adapted continuous infusion of remifentanil 0.150.4 µg kg1 min1 was administered. Frequency and intensity (VAS 0100 mm) of nausea, retching, and vomiting were assessed by patients and blinded investigators during and after the procedure.
Results. Patient characteristics, baseline values, duration of ESWL, and total dose of remifentanil did not differ between groups. The frequency (Group 1/Group 2; 20/55%; P<0.05) and mean (SD) maximal intensity [15 (9)/45 (14) mm; P<0.05] of nausea during 24 h was significantly reduced after dolasetron and discharge times in Group 1 were less than Group 2 [22 (14)/45 (28) min; P<0.05].
