摘要
52例低温体外循环心内直视术后进行ICU监护的患者必须行持续人工通气,全部病例选用肌松剂ATC应用,未用或少用镇静药,效果满意。52例均于进入ICU立即起用ATC微泵滴注,用量为3us-6ug/kg/min,总使用时间5~48小时,循环稳定,停用ATC60~90分钟即可拔除气管导管,全部病例无呼吸抑制并发症,未用拮抗药。本组用ATC后,清醒时能睁眼,意识清楚,合作,循环指标稳定,机械通气正常,四肢肌松,四串电刺激器在T3/T10.7以下,未用镇静剂30例,于晚间用少量镇静药入睡22例。本组进入ICU危重患者应用ATC有如下优点:(1)清醒合作,不燥动,减少全身氧耗。(2)保持机械通气稳定,氧供正常,有利心脏功能恢复。(3)ATC具有作用时间短,对心肌及循环无影响;不依赖肝肾排泄,故对肝肾无毒性,且无蓄积作用和残留肌松作用。(4)持续用药减少间断用镇静药的患者燥动对抗呼吸机等不良影响。本组实践证明,在严格监护ICU危重患者应用ATC对重要器官无不良反应,停药短时内恢复肌力,顺利脱机。
Fifty two patients entered ICU after heart operation with cardiopulmonary bypass.These patients with ventilation atracurium (ATC) were given 3μg~6μg/kg/min for 5 ̄48 hours. No complications happened.After ATC was used, the patients could open eyes, and cooperate with the doctor when they regain consciousness.The circulation index was normal.The limbs of these patients relaxed. In the 52 cases,30 didn′t use sedatives, and 22 used senall dose of sedatives for sleep at night.We conclude that ATC does not require hepatic or renal function for termination of effect and action is terminated by the “Hoffman elimination” and ester hydrolysis.The time of effect is short and there is no cumulation effect. There is no vagal or ganglionic blocking activity,so ATC does not influence circulation and myocardial function.Maintenance relexation keeps ventilation steady and oxygen supply normal.
