【摘要】 目的：探讨营养支持对慢性阻塞性肺病并发营养不良（ｍａｌｎｏｕｒｉｓｈｅｄｃｈｒｏｎｉｃｏｂｓｔｒｕｃｔｉｖｅｐｕｌｍｏｎａｒｙｄｉｓｅａｓｅ，ＭＮＣＯＰＤ）患者运动耐量的影响。方法：ＭＮＣＯＰＤ缓解期患者３０例，按营养支持的方案不同分为两组。Ａ组（营养膳加静脉营养）１５例，Ｂ组（营养膳）１５例。治疗前及１周后作运动试验。结果：Ａ组功率氧耗（△·ＶＯ２／△Ｗ）、运动通气氧耗（·ＶＯ２／Ｗ／·ＶＥ）治疗后较治疗前及Ｂ组降低。结论：附加短期静脉营养支持可降低运动氧耗量，提高运动耐量更多还原

【Abstract】 Objective:To investigate effects of short term intravenous nutritional support on exercise endurance in malnourished COPD patients(MNCOPD).Methods:30 patients with MNCOPD were divided at random into 2 groups:group A 15 cases treated with oral and intravenous injection of nutritional support and group B 15 cases treated with oral administration of nutritional support only.Exercise test was made before and one week after the treatment.Results:Oxygen cost of work(△AV·UO 2/△W) and oxygen cost of ventilation and workload(AV·UO 2/W/AV·UE) were significantly smaller in group A after the management than both before the management and in group B.Conclusions:Short term intravenous nutritional support can decrease oxygen consumption and improve exercise endurance.更多还原
