摘要: 为观察硬膜外穿刺前应用国产咪达唑仑注射液的最适剂量,选择150例病人随机双盲分成5组,每组30人。第1组为对照组,第2、3、4、5组分别静脉注射咪达唑仑注射液0.02、0.04、0.06、0.08mg/kg。观察平均动脉压、心率、呼吸、血氧饱和度、记忆及镇静程度的变化。第1、2组硬膜外穿刺操作后平均动脉压增加2.3kPa、心率平均增加11次/min,第1、2组间无差异;且2组用药前后平均动脉压与心率无差异;第3组操作前后和用药前后平均动脉压、心率均无显著差异。用药后与用药前相比,第4、5组平均动脉压下降,心率减慢,但均在正常范围;用药后组间平均动脉压与心率无差异。呼吸及血氧饱和度各组均在正常范围。第1、2、3、4、5组记忆率分别为100%、87%、40%、17%及0,用药后均有顺行性遗忘作用,第3、4组顺行性遗忘作用强。镇静程度:第1~4组均为清醒或入睡可唤醒,第5组有9例病人入睡唤醒困难但睫毛反射存在,用药后第2、3、4组患者均可主动配合操作,第5组有少数病人不能主动配合。提示:硬膜外穿刺前静脉注射0.04~0.06mg/kg咪达唑仑可稳定生命体征,消除对不良刺激的记忆,且患者可主动配合操作,因此,值得在硬膜外穿刺前应用。

Abstract: To determine the optimal dosage of midazolam administered in the epidural puncture. Method: 150 patients were divided into 5 groups randomly, 30 patients each group. Group 1 were given saline 2 mLiv before epidural puncture. Group 2~5 had 0.02、0.04、0.06、0.08 mg/kg midazolam adiministered before epidural puncture respectively. The changes of MAP, HR, R, SpO2, memory and sedative degree were observed. Results: The MAP, HRincreased dramatically by 2.3 kPa and 12 bpm in group 1 and group 2 and there were no differences in MAP and HR changes between the two groups. There were no differences in MAP and HR changes in group 3 post-puncture. After midazolam was administered MAP and HR decreased respectively by 1.1 kPa and 8 bpm in group 4 and 5. RR AND SpO2 kept normal in all groups. The memory rates were 100%, 87%, 40%, 17% and 0 in group 1~5 respectively. Sedative degree: the patients kept conscious or could be awaked easily in group 1~4 and there were 9 patients in group 5 with difficulty to awake but the lid reflex existed. Midazolam of 0.04~ 0.06 mg/kg iv before epidural puncture provides ideal procedural state, stabilizes the Vital signs, eliminates the vicious memory and brings patients comfort.
