目的:探讨早期肠内营养对预防COPD机械通气患者应激性溃疡出血的临床效果。方法:60例COPD机械通气患者随机分成实验组和对照组,每组30例。对照组早期给予肠外营养(PN),7d后再逐渐过度至肠内营养;实验组机械通气24h内即行肠内营养支持(EN);比较两组患者的消化道出血及胃液pH值变化情况。结果:实验组上消化道出血发生率明显少于对照组(P<005)。结论:早期肠内营养可中和患者的胃酸,升高胃液pH值,能有效预防COPD机械通气患者应激性溃疡的发生。
Objective: To investigate the clinical effect of early enteral nutrition on the prevention of stress ulcer bleeding in COPD patients. Methods: Sixty COPD patients with mechanical ventilation were randomly divided into experimental group and control group, 30 cases in each group. The control group was given parenteral nutrition (PN) early, and then gradually over to enteral nutrition after 7 days. The experimental group received enteral nutrition support (EN) within 24 hours of mechanical ventilation. The changes of gastrointestinal bleeding and gastric pH in the two groups were compared . Results: The incidence of upper gastrointestinal bleeding in the experimental group was significantly less than that in the control group (P <005). Conclusion: Early enteral nutrition can neutralize the gastric acid in patients and increase the pH value of gastric juice, which can effectively prevent the occurrence of stress ulcer in COPD patients.
