Abstract

Background/Aims: Propofol is an effective sedative drug in endoscopic procedures, but it has potentially serious adverse effects, so close monitoring of the vital signs should be performed during endoscopy. This study was undertaken to determine the adequate induction dose of propofol for safe and effective sedation during esophagogastrodudenoscopy (EGD) in persons 60 years or older. Methods: Three hundred patients who visited our hospital for EGD were randomly assigned to three groups (A,B and C). An initial induction dose of 0.5 mg/kg, 0.75 mg/kg and 1.0 mg/kg of propofol was allocated to groups A, B and C, respectively. Results: The 0.5 mg/kg, 0.75 mg/kg and, 1 mg/kg dose of propofol were all safe as an initial dose of propofol for achieving sedation during EGD in persons 60 years or older. There was no difference in the total amount of propofol among the three groups. Group C had a significantly shorter induction time and a lower dose was required for an additional injection of propofol without increasing adverse events, as compared to the two other groups. Conclusions: We suggest that 1 mg/kg of propofol is an effective induction dose for sedation during EGD in persons 60 years or older.

목적: 상부 위장관 내시경에 사용되는 profopol은 효과적이며 안전한 약물이다. 그러나 강력한 진정 작용이 있어 내시경 시행 중 면밀한 관찰이 필요하다. 고령일수록 약물 투여에 따르는 부작용이 높지만 노인에서의 적정한 진정 유도량에 대한 연구는 많지 않았다. 본 연구는 60세 이상의 노인에서 상부 위장관 내시경을 시행시 안전하고 효과적인 propofol의 적정 유도 용량을 알기 위해 연구를 진행하였다. 대상 및 방법: 2009년 6월부터 2010년 2월까지 본원 소화기 내과 외래를 내원하여 건강 검진을 목적으로 내시경 검사를 시행한 300명의 대상자를 무작위로 진정 유도를 위한 초기 투여 용량에 따라 3군으로 분류하였다. A군은 0.5 mg/kg, B군은 0.75 mg/kg, C군은 1.0 mg/kg의 propofol을 투여하였다. 결과: 60세 이상의 노인에서 상부 위장관 내시경시 초기 유도량으로는 0.5 mg/kg, 0.75 mg/kg, 1 mg/kg 모두 부작용 없이 안전하고 효과적으로 진정 유도 도달하였다. 세 군간에 총사용량은 차이가 없었다. 진정 유도 후 추가적으로 투여된 propofol양은 A군에서 $38.6{\pm}1.80$ mg, B군에서 $22.0{\pm}1.74$ mg, C군에서 $11.8{\pm}1.66$ mg으로 통계적으로 유의할 만큼 C군이 적었다(p<0.001). 진정 유도까지 소요되는 시간도 A군에서 $85.14{\pm}32.43$초, B군에서 $60.34{\pm}26.10$초, C군이 $49.47{\pm}29.49$초로 C군이 가장 짧은 시간에 진정 유도에 도달하였다(p<0.001). 세군간 부작용 발생에서 유의한 차이가 없었다. 결론: 60세 이상의 고령에서 의식하진정 내시경 검사에 propofol의 적정 유도 용량은 1 mg/kg이 더 효과적이다.
