Abstract: 目的 比较异丙酚、咪达唑仑或依托咪酯复合舒芬太尼麻醉诱导对患者眼内压(IOP)的影响.方法 拟在全麻下择期手术患者45例,年龄20-40岁,ASA分级Ⅰ或Ⅱ级,按照随机数字表法,将其随机分为3组(n=15):异丙酚组(P组)、咪达唑仑组(M组)和依托咪酯组(E组).麻醉诱导:P组、M组和E组分别静脉注射异丙酚2.0 mg/kg、咪达唑仑0.2 mg/kg及依托咪酯0.3 mg/kg后,依次静脉注射舒芬太尼0.2 μg/kg与顺阿曲库铵0.2 mg/kg,行气管插管术.于麻醉诱导前l min(T0)、气管插管前(T1)、气管插管后即刻(T2)、气管插管后1 min(T3)和2 min(T4)时测定IOP和MAP.结果 与P组比较,M组和E组低眼压发生率降低(P<0.01);与E组比较,P组和M组高眼压发生率降低(P<0.05).P组、M组和E组MAP与IOP的相关系数分别为0.831、0.889和0.806(p<0.05),相关系数组间比较差异无统计学意义(P>0.05).结论 咪达唑仑复合舒芬太尼麻醉诱导对IOP影响较小,MAP的波动程度是麻醉诱导引起IOP变化的主要因素.
