Abstract:

目的观察椎管内麻醉辅以持续靶控输注丙泊酚和咪达唑仑的镇静效果。方法在腰硬联合麻醉下择期行下腹部手术的成年病人60例,ASAI~II级,随机分为两组,每组30例,予以丙泊酚(I组)和咪达唑仑(II组)持续靶控输注镇静。分别在入室平卧10min(T?1)、静脉给予镇静药后2min(T?2)、5min(T?3)、10min(T?4)、20min(T?5)、30min(T?6)、手术结束前10min(T?7)、手术结束时(T?8)8个时间点记录OAA/S镇静评分、BIS值及心率、血压、呼吸和血氧饱和度。结果两组患者生命体征均平稳,与给药前比较,丙泊酚组给药后2、5、10、20和30minBIS值明显下降(?P?<0?05);OAA/S评分在给药后2min到30min都有明显下降(?P?<0?05)。咪达唑仑组与给药前比较,给药后5min到30minBIS值明显下降(?P?<0?05),OAA/S评分也在给药后5min到手术结束前10min都有明显下降(?P?<0?05)。结论椎管内麻醉辅以丙泊酚、咪达唑仑持续靶控输注镇静效果良好,且对生命体征影响小;BIS值对丙泊酚和咪达唑仑镇静监测反应灵敏。
