Hemodynamic effects of remifentanil for patients under General anesthesia during arthroscopic shoulder surgery

Background: Although the arthroscopic procedure was less painful, we often observed the poorly controlled intra-operative hemodynamics. This study was performed to investigate the effects of remifentanil on hemodynamics during arthroscopic shoulder surgery. Methods: Sixty patients (ASA class 1 and 2) who were scheduled for arthroscopic shoulder surgery were randomly allocated to four groups. After anesthesia was induced with thiopental sodium 5 m g /k g ，rocuronium bromide 0.9 mg/kg and maintained with 2 vol% sevoflurane, 50% N2O，either saline 20 ml/hr, remifentanil 0.06 pg/kg/min (Groups C, R respectively) was infused and then the hemodynamics were recorded. Results: The hemohynamics were significantly more stable in Group R than C (P<0.05). Conclusions: Remifentanil 0.06 jjg/kg/min was effective at controlling the hemodynamic changes induced by shoulder arthroscopic surgery.
