吗啡-芬太尼复合麻醉下非体外循环冠状动脉旁路移植术患者的转归

目的 探讨吗啡-芬太尼复合麻醉下非体外循环下冠状动脉旁路移植术患者的转归.方法 拟在非体外循环下行冠状动脉旁路移植术的患者72例,年龄41～64岁,随机分为2组(n=36):芬太尼复合麻醉组(F组)和吗啡-芬太尼复合麻醉组(MF组).静脉注射芬太尼10～20μg/kg、咪达唑仑0.1 mg/kg、依托咪酯0.3 mg/kg和维库溴铵0.1 mg/kg进行麻醉诱导,气管插管后行机械通气.麻醉维持:MF组静脉输注吗啡0.15 mg·kg-1·h-1+芬太尼8μg·kg-1·hZ-1,F组静脉输注芬太尼10μg·kg-1·h-1,2组均吸入0.5%～2.0%异氟烷,间断静脉注射维库溴铵4 rag.2组术后进行静脉镇痛,MF组和F组分别静脉输注吗啡0.75 mg/h吗啡和芬太尼10μg/h.分别于术前(基础状态)、术后1、2、3 d进行恢复质量评分(QoR评分).于拔除气管导管后15 min、4 h、24 h时进行Ramsay镇静评分.记录术后不良反应的发生情况.结果 与F组比较,MF组术后QoR评分升高,术后发热发生率降低(P＜0.05或0.01),Ramsay镇静评分和其他不良反应的发生率差异无统计学意义(P＞0.05).结论与芬太尼复合麻醉比较,吗啡-芬太尼复合麻醉有利于非体外循环下冠状动脉旁路移植术患者预后.

Outcomes of patients undergoing off-pump coronary artery bypass grafting under morphine-fentanyl combined anesthesia

Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. Methods Seventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. Results QoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. Conclusion Morphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.
