摘要 目的评价小剂量右美托咪定联合芬太尼和异丙酚用于无痛膀胱镜检术诊疗的临床效果。方法选择拟行无痛膀胱镜检术患者80例,年龄35-65岁,ASA分级Ⅰ或Ⅱ级,将患者随机均分为2组:小剂量右美托咪定组(D组)和对照组(C组),每组40例。D组术前15min静脉泵注右美托咪定负荷剂量0.6μg/kg,继而以0.2μg·kg^(-1)·h^(-1)的速率维持至术毕,C组给予等容量生理盐水。负荷剂量输注完毕后两组均静脉注射芬太尼1μg/kg,然后缓慢推注异丙酚直至患者入睡,术中按需追加异丙酚。记录患者麻醉诱导前(T0)、诱导后2min、镜检5min及术毕清醒(T_1-T_3)时的心率(HR)、平均动脉压(MAP)、脉搏氧饱和度(SpO_2)、OAA/S及Ramsay镇静评分;同时记录患者的异丙酚用量、麻醉诱导时间、苏醒时间及不良事件发生情况。结果与C组比较,D组T_1-T_2时HR及OAA/S评分降低,MAP及Ramsay镇静评分升高,麻醉诱导时间缩短,异丙酚用量减少,术中低血压、体动反应、舌后坠及呼吸抑制发生率降低(P<0.05),术后苏醒时间及恶心呕吐发生率差异无统计学意义(P>0.05)。结论小剂量右美托咪定联合芬太尼和异丙酚用于无痛膀胱镜检术较单用芬太尼和异丙酚血流动力学更稳定,呼吸抑制更小,且镇静效果更好,可安全用于无痛膀胱镜检术诊疗中。
