    Abstract:
    BACKGROUND: Nitrous oxide (N2O) has been suggested to contribute to bowel distension, resulting in worsened operating conditions for laparoscopic surgery, and to increase incidence of postoperative nausea and vomiting. Therefore, our objective was to assess the feasibility of two remifentanil-based anaesthetic regimens free from N2O with special regard to recovery profile, postoperative analgesic demand and side effects in patients undergoing laparoscopic cholecystectomy. METHODS: Fifty patients (ASA I-II, 23-65 yr) were randomly assigned to receive remifentanil-based anaesthesia in conjunction with propofol (group R/P) or desflurane (group R/D). After standardised induction of anaesthesia, analgesia was continued with remifentanil in all patients. For maintenance of hypnosis, propofol or desflurane were used in concentrations to ensure loss of consciousness, lack of awareness, and maintenance of heart rate and blood pressure within +/- 25% of initial values. At the end of surgery all anaesthetics were discontinued without tapering and early emergence and recovery were recorded. Pain scores were assessed by using a visual analogue scale. Patient-controlled analgesia with i.v. piritramide was used for treatment of postoperative pain and recorded for 90 min in the postanaesthesia care unit (PACU). In addition, side effects were noted. RESULTS: Early emergence from anaesthesia did not differ between the groups. In group R/P, time to eye opening, spontaneous respiration and extubation was 4.4 +/- 2.9 min, 5.2 +/- 3.4 min and 5.5 +/- 3.3 min respectively, compared with 4.7 +/- 2.7 min, 5.3 +/- 2.4 min and 5.7 +/- 2.5 min in group R/D. While pain scores did not differ between both groups on admission to the PACU, patients receiving desflurane required more i.v. piritramide as compared to those receiving propofol, 22.0 +/- 6.5 mg and 17.9 +/- 7.0 mg, respectively (P<0.05). Nausea was less frequent after propofol (16% vs. 48%, P<0.05). CONCLUSION: In patients undergoing laparoscopic cholecystectomy, remifentanil-based anaesthetic regimens in conjunction with propofol or desflurane are suitable and allow for rapid recovery from anaesthesia. However, the use of propofol results in less postoperative analgesic consumption and nausea as compared to desflurane.
