Abstract:
Objective The aim of this study was to investigate different dosages and effects of dexmedetomidine for prevention of postanesthetic shivering. Methods One-hundred twenty patients scheduled for laparoscopic surgery were randomly allocated in four groups: before the operation, slowly injected 0.9% normal saline (group S, dexmedetomidine 0.5 μg/kg (group D0.5), dexmedetomidine 0.75 μg/kg (group D0.75), dexmedetomidine 1.0 μg/kg(group D1.0). HR and rectal temperature[C2] were continually monitered during and after operation, time to extubation was measured. Grades of shivering were recorded. Pain evaluation was assessed by a visual analogue scale, sedation was evaluated by Modified Observer′s Assessment of Alertness/Sedation scale. Results The patients in group S showed a significantly higher HR and postoperative incidence of shivering than those in group D0.75 and group D1.0, (P < 0.05). but the extubation time in groupd D0.75 and group D1.0 were longer than patients in group S (P<0.05). Conclusion Slowly injected dexmedetomidine 0.75 μg/kg or 1.0 μg/kg can prevent postanesthetic shivering in laparoscopic surgery effectively.
