咪达唑仑口服溶液用于幼儿超声心动图检查镇静的可行性和效果

Feasibility and Effectiveness of Midazolam Oral Solution in Sedation for Infants During Echocardiographic Examination

目的评价咪达唑仑口服溶液用于幼儿超声心动图检查镇静的可行性和有效性。方法选择在镇静下行超声心动图检查的患儿240例,年龄1~3岁,记录相关基线数据,计算机模拟产生随机数字表法将患儿分为0.3 mg·kg^(-1)咪达唑仑口服溶液组(M_(1)组)、0.5 mg·kg^(-1)咪达唑仑口服溶液组(M_(2)组)、0.7 mg·kg^(-1)咪达唑仑口服溶液组(M_(3)组)、0.5 mL·kg^(-1)10%水合氯醛灌肠组(C组),每组各60例,以各组相应的方法进行镇静。5分面部特征量表评价镇静依从性,Ramsay镇静量表评估镇静效果,记录镇静起效时间、持续时间。结果各组患儿镇静时5分面部特征量表评分差异有统计学意义(F=17.50,P<0.017),M_(1)、M_(2)和M_(3)组评分明显高于C组;M_(1)和M_(2)组镇静起效时间长于C组(P<0.017),镇静持续时间短于C组(P<0.017);M_(3)组与C组镇静起效时间(P=0.85)、持续时间(P=0.50)差异无统计学意义;M_(1)和M_(2)组镇静起效时间明显长于M_(3)组(P<0.017),而镇静持续时间明显短于M_(3)组(P<0.017),差异有统计学意义。结论幼儿在心脏超声镇静下检查应用咪达唑仑口服溶液的依从性优于10%水合氯醛灌肠且不良反应少,其中0.7 mg·kg^(-1)剂量咪达唑仑口服溶液镇静起效快,效果确切。

Objective To evaluate the acceptability and effectiveness of different doses of midazolam oral solution in sedating infants during echocardiographic studies.Methods Two hundred and fourty patients aged 1 to 3 years who underwent echocardiographic study in sedation in our hospital were enrolled in this study.After recording the baseline data of all infants,they were randomly divided into four groups:0.3 mg·kg^(-1)midazolam oral solution group(M_(1) group),0.5 mg·kg^(-1)midazolam oral solution group(M_(2) group),0.7 mg·kg^(-1)midazolam oral solution group(M_(3) group)and 0.5 mL·kg^(-1)10%chloral hydrate administrated rectally group(C group),60 case per group,and the sedation was performed in the corresponding method of each group.The 5-point facial hedonic and Ramsay scales were used to evaluate acceptability and effectiveness in sedation.The onset time and duration time of sedation were recorded.Results Compared with the C group,the 5-point facial hedonic scale scores in M_(1),M_(2),and M_(3) groups increased during sedation(F=17.50,P<0.017).The onset time of sedation in the M_(1) and M_(2) groups was longer than that in the C group(P<0.017),and the duration time of sedation in the M_(1) and M_(2) groups was shorter than that in the C group(P<0.017).There was no significant difference in the onset time(P=0.85)and duration time(P=0.50)of sedation between the M_(3) and C groups.The onset time of sedation in the M_(1) and M_(2) groups was longer than that in the M_(3) group(P<0.017),and the duration time of sedation in the M_(1) and M_(2) groups were shorter than that in the M_(3) group(P<0.017).Conclusions The acceptability of infants with midazolam oral solution sedation under echocardiographic study was better than that of 10%chloral hydrate administrated rectally.There were fewer adverse reactions with the midazolam oral solution.The 0.7 mg·kg^(-1)midazolam oral solution had a rapid onset of sedation and definite effect.
