来自:中华实用医药杂志 纳洛酮治疗Ⅱ型呼吸衰竭肺性脑病的疗效和安全性评价 【摘要】 目的 观察评价纳洛酮治疗Ⅱ型呼吸衰竭肺性脑病临床疗效及安全性。方法 将入选61例病例随机分为治疗组及对照组,两组均予以积极控制感染,持续低流量吸氧(给氧浓度为30%~40%,氧流量为1~3L/min,鼻导管给氧法),解痉平喘,止咳化痰,保持气道通畅,维持酸碱、水、电解质平衡,营养支持等综合治疗。治疗组在此基础上加用纳洛酮注射剂(0.4mg/支),首剂负荷量0.8mg加入生理盐水20ml中静脉推注,以后给予纳洛酮注射剂2mg加入生理盐水60ml中,每日2次,用微量泵24h持续静脉泵入,连用3天。结果 治疗后,治疗组总有效率显著高于对照组(P<0.05);动脉血气分析指标:动脉血氧分压(PaO2)显著高于对照组(P<0.05)、动脉血二氧化碳分压(PaCO2)显著低于对照组(P<0.05);治疗过程中无不良反应发生。结论 纳洛酮治疗Ⅱ型呼吸衰竭肺性脑病临床疗效确切、安全。 【关键词】 纳洛酮;Ⅱ型呼吸衰竭;肺性脑病;疗效 The observation of the clinical effect and safety of naloxone in treatment of chronic respiratory failure with pulmonary encephalopathy TONG Xiao-wen,ZHANG Zhi-ling,ZHOU Long-nv.

Methods 61 patients with chronic respiratory failure with pulmonary encephalopathy were randomly divided into 2 groups,30 cases in the control group were received basic therapy including anti-infection,relieving airway spasm and asthma,etc.31 case in the treating group were given naloxone injection 2mg intravenously by microsyringe twice a day for 3 days. Results After treatment,the total effective rate in the treating group was significantly higher than that in the control group (P<0.05).PaO2 in the treating group was significantly higher than that in the control group(P<0.05.PaCO2 in the treating group was significantly lower than that in the control group(P<0.05).Conclusion Naloxone is an effective and less side-effect medicine for treatment of chronic respiratory failure with pulmonary encephalopathy. 【Key words】 naloxone;respiratory failure;pulmonary encephalopathy;effect Ⅱ型呼吸衰竭会导致严重的低氧及高碳酸血症,使患者出现一系列临床症状:如呼吸困难、紫绀、电解质和酸碱代谢失衡甚至昏迷等,可直接危及患者生命,是我们急诊科常见急危重症。纳洛酮是特异性阿片受体拮抗剂,其可直接、有效地拮抗和逆转β-内啡肽所致的中枢性呼吸抑制作用,改善缺氧和二氧化碳潴留而发挥治疗作用[1]。我科应用纳洛酮治疗Ⅱ型呼吸衰竭肺性脑病取得较好疗效且无不良反应发生,现将结果报道如下。 1 资料与方法 1.1 一般资料 选择近3年(2002年1月~2004年12月)我院急诊科所收治的Ⅱ型呼吸衰竭伴肺性脑病患者61例,所有病例均符合国内“慢性阻塞性肺病诊治规范” [2]。将入选61例病例随机分为治疗组及对照组。其中治疗组31例,男20例,女11例;年龄65~85岁,平均73.84±4.98岁;病程5~20 年,平均10.97±4.29年。对照组30例,男20例,女10例;年龄63~85岁,平均73.23±5.36岁;病程4~20年,平均9.80± 3.81年。两组病例在性别、年龄、病程上差异无显著性(P>0.05),两组病例治疗前均有明显
