Sevoflurane과 Remifentanil로 마취유도 시 저용량 Rocuronium이 기관내 삽관조건에 미치는 영향

Background: We evaluated the effect of low doses of rocuronium on tracheal intubating conditions and hemodynamic changes during induction of anesthesia with 8 vol% sevoflurane and remifentanil 1μg/kg. Methods: Eighty four patients were randomized into one of three groups; Group I, II, III. Each group received normal saline, 0.3, 0.45 mg/kg of rocuronium respectively. Predetermined drugs for each group and remifentanil 1μg/kg were administered during induction of 8 vol% sevoflurane. After induction of 8 vol% sevoflurane, tracheal intubation was preformed. The tracheal intubation conditions and hemodynamic responses to tracheal intubation were assessed. Results: Tracheal intubation was successful in all patients. The incidence of clinically acceptable intubating conditions was 79% in Group I, 100% in Group II, and 100% in Group III. There was no significant difference in intubating condition between Group II and Group III. The hemodynamic responses to tracheal intubation were blunted in all groups. Conclusions: After induction with 8 vol% sevoflurane and remifentanil 1μg/kg, low-dose rocuronium provides more satisfactory tracheal intubation conditions. KCI Citation Count: 1
