96例重症患者持续鼻饲与间歇鼻饲的应用研究

Application study of constant or intermittent nasal feeding in 192 patients with severe diseases

目的探讨持续鼻饲与间歇鼻饲的利弊,为临床正确选择鼻饲方法提供依据。方法选择重症监护室鼻饲患者192例,随机分为观察组和对照组各96例,对照组按照常规持续鼻饲,观察组采用间歇鼻饲的方法 ,记录两组患者腹胀、腹泻、胃潴留、呛咳、反流等并发症发生的次数,胃液pH值。结果持续鼻饲与间歇鼻饲方法在腹胀、腹泻、反流、呛咳、胃潴留等并发症的发生率差异无统计学意义(P>0.05)。两种鼻饲方法患者的胃液pH值差异有统计学意义(P<0.05),间歇鼻饲胃液pH值更接近生理值。结论间歇鼻饲优于持续鼻饲,对胃液pH值影响更小,有利于患者营养的吸收,不会增加并发症的发生率。

Objective To compare the benefit-risk between constant nasal feeding and intermittent nasal feeding,to offer some scientific evidences to choose appropriate nasal feeding way.Methods 192 patients with severe diseases were divided into two groups： control group and observed group,96 cases in each group.The patients of the control group were fed constantly from nasal feeding tube.In the observed group,the patients were fed intermittently from nasal feeding tube.We analyzed the PH value of stomach juice in two groups.The incidence rate of complications including abdominal distention,diarrhea,gastric retention,cough and reflux was compared between the two groups.Results The incidence rate of complications in two groups had no significance（P〉0.05）.The PH value of stomach juice in observed group was closed to physiological state.Conclusion Intermittent nasal feeding is better than constant nasal feeding.Intermittent nasal feeding hardly influences the PH value of stomach juice and is beneficial to nutrient absorption and reduce the complication rate,which should be used widely in clinical nursing.
