摘要
观察四种不同剂量咪唑安定的健忘、镇静及心血管抑制作用。结果表明,咪唑安定0.08mg/kg,最大健忘率90%,持续约5分钟。0.10mg/kg1分钟健忘率达100%,持续约15分钟。0.13、0. 16mg/kg分别于 1分钟和 30秒达100%健忘,持续约30分钟。≤ 0.10mg/kg多数呈浅睡或嗜睡状态,少数呈深睡状态,无一例意识消失;血流动力学变化无统计学意义。≥0. 13mg/kg 60%呈深睡状态,部分病例意识消失;SP、EF%、SVI、CI明显降低,少数指标30分钟时仍显著低于对照值。提示咪唑安定的健忘、镇静及心血管抑制作用与剂量相关,作为健忘镇痛复合麻醉手术,咪唑安定用量以0.10mg/kg为宜。
To evaluate the amnestic effect of midazolam,eighty adult patients ; ASA grade I to ,scheduled to undergo abdominal or lower extremity operation, were randomly assigned to receiving intlavenous injection of midazlam at a dose of 0. 08(group I ), 0. 1 (group ), 0. 13 (group ) or 0. 16mg. kg-1 (group ) respectively with 20 cases in each group. The maximum incidence and duration of amnesia were determined respectively at 0. 5, 1, 5, 15, 30 and 60 min immediately following the administratin of midazolam in four groups by subject's recalling the characteristics of the picture,which was shown to the subject in 10 to 15 seconds before the injection of midazolam. The hemodynamic parameters wele observed by the impendance cardiography. The results showed that the Incidences of amnesia were 90%, 100% .100%, 100%,and its durations were 5, 15, 30 and 30 mins in group and individually. The hemodynamics kept statistically stable in group during the whole procedures (P>0. 05),and systolic blood pressure,cardiac index and systemic vascular index were decreased to and maintained at lower levels in 30 mln in group and (P<0.05 or 0. 01). It is suggested that midazolam may produce a dose--related amnetsic effects,and at a dose of 0.1mg. kg-1 is suitable for clinical combined anesthesia.
