【摘要】:目的比较右美托咪定注射剂和丙泊酚注射剂在小儿磁共振(MRI)检查中的镇静效果。方法将90例1~6岁进行3.0TMRI检查的患儿随机分为试验组和对照组,每组45例。对照组静脉泵注丙泊酚负荷剂量2.5 mg·kg~(-1),给药时间10 min,接着给予80~100μg·kg~(-1)·min~(-1)维持;试验组静脉泵注右美托咪定负荷剂量1μg·kg~(-1),给药时间10 min,接着给予0.3~0.8μg·kg~(-1)·h~(-1)维持。记录给药前(T0)、给药后10 min(T_1)、开始检查前(T_2)、MRI检查开始后5min(T_3)、MRI检查完毕(T_4)、患儿返回病房(T_5)的平均动脉压(MAP)、心率(HR)、脉搏氧饱和度(Sp O2)、呼吸频率(RR)、镇静起效时间、苏醒时间、苏醒后烦躁发生率、药物不良反应、MRI检查质量和时间。结果与T0比较,试验组患儿T_1-T_4的MAP和HR降低(P0.05),T5恢复至基础水平;对照组在T_1-T_4MAP、RR降低(P0.05),T_5时点恢复至基础水平,与试验组比较,在T1-T3MAP和RR显著低于试验组(P0.05),在T_1-T_4HR显著高于试验组(P0.05)。对照组镇静起效时间和苏醒时间显著短于试验组(P0.05),但苏醒后烦躁的发生率和低氧饱和度的发生率显著高于试验组(P0.05)。试验组MRI的检查质量显著高于对照组,检查时间显著短于对照组(P0.05)。结论与丙泊酚注射剂相比,右美托咪定注射剂在小儿磁共振检查中能提供满意的镇静深度,对患儿呼吸和血流动力学影响小,药物不良反应发生率低,但是镇静的起效时间和苏醒时间长于丙泊酚。
[Abstract]:Objective to compare the sedation effect of dexmetomide injection and propofol injection in children with magnetic resonance (MRI). Methods 90 children aged 1 years and 6 years old were randomly divided into experimental group (n = 45) and control group (n = 45). In the control group, propofol loading dose was 2.5 mg kg~ (- 1), administration time was 10 min, and 80 ~ 100 渭 g kg~ (- 1) min~ (- 1) was maintained, while in the experimental group, the loading dose of right metomipramine was 1 渭 g kg~ (- 1), and the administration time was 10 min, followed by 0.3 ~ 0.8 渭 g kg~ (- 1) h ~ (- 1).
