PATIENTS AND METHODS: Eighty patients were randomly divided into two groups: Group R (n=40) and S (n=40) received remifentanil 4 mu g/kg intravenously or 1 mu g/kg respectively. Anesthesia was induced with 2 mg/kg propofol in both groups. Intubation was performed after bolus administration of 10 ml saline as a placebo or 1 mg/kg of succinylcholine in Group R and S respectively. Remifentanil infusion was initiated at 0.025 mu g/kg in each groups. RESULTS: Intubation conditions were similar in both groups. The mean arterial pressure (MAP) values at post-induction period were significantly lower in the Group S than in the Group R (p = 0.001). The requirement for ephedrine in Group R was found to be significantly lower than Group S (p = 0.023). Recovery times were significantly shorter (p = 0.001) and recovery scores were significantly higher (p = 0.021) in Group R. Time to patient could respond to commands was significantly longer in the Group S (p = 0.001). The surgeon's satisfaction score was significantly higher in Group R (p = 0.001). CONCLUSIONS: It was concluded that remifentanil without muscle relaxants provides similar intubating conditions as that provided by succinylcholine, and remifentanil is superior to succinylcholine with regard to haemodynamic stability and recovery duration.eninfo:eu-repo/semantics/closedAccessMicrolaryngoscopyRemifentanilSuccinylcholineIntubationArticle171419671973238778642-s2.0-84884174037Q2WOS:000325203900020Q4
