摘要 目的评价瑞芬太尼辅助颈丛阻滞对甲状腺手术镇静和镇痛效果。方法择期颈丛阻滞麻醉下行甲状腺次全切除术患者60例,ASAⅠ或Ⅱ级,随机分为3组(n=20):对照组(C组),瑞芬太尼恒速输注组(R组)和瑞芬太尼靶控输注组(TCI组)。颈丛阻滞效果确切后,术前5min,R组持续静脉注射瑞芬太尼2μg/(kg·h);TCI组靶控输注瑞芬太尼血浆靶浓度1.25ng/ml,C组持续静脉注射生理盐水直到手术结束。观察并记录患者MAP、HR、RR、SpO2,视觉模拟疼痛评分(VAS)、镇静评分(OAA/S评分),不良反应(呼吸抑制、肌肉僵硬、恶心呕吐)及术后患者满意度。结果与T0组比较,C组T2时MAP升高,T1和T2时HR明显增快(P〈0.05);与C组比较,R组和TCI组T2时MAP降低,T1和T2时HR明显减慢(P〈0.05,P〈0.01)。OAA/S评分比较,R组和TCI组达4分的例数明显多于C组(P〈0.01)。VAS评分比较,R组和TCI组优良的例数明显多于C组(P〈0.01)。与C组比较,R组和TCI组各有2例和1例出现轻微的呼吸抑制,不良反应发生率差异无统计学意义。结论瑞芬太尼辅助颈丛阻滞下行甲状腺手术安全有效,恒速输注与靶控输注法的镇静和镇痛效果相当。
