危重症患者肠内营养液间歇泵入效果观察

Intermittent pump-assisted enteral nutrition to prevent complications in critically ill patients

目的观察危重症患者接受肠内营养治疗的最佳输注方式,减轻反流、误吸风险。方法将60例ICUEN患者随机分为对照组和观察组各30例。对照组采用持续泵入输注(16h),观察组采用间歇泵入输注,即输注90min暂停150min,4次/d。结果两组胃残留液、胃液pH值,营养液反流入口、胃管内营养液反流发生率比较,差异有统计学意义(P<0.05,P<0.01)。结论肠内营养间歇泵入输注方法可减少患者胃残留液量和降低胃液pH值,有效减少反流、误吸发生率,是ICU患者较理想的鼻饲方法。

Objective To explore an optimal method for providing enteral nutrition （EN） to critically ill patients, and to reduce gastro-oesophageal reflux and aspiration. Methods Sixty ICU patients were randomized to 2 EN administration groups of 30.. continuous or intermittent. Solutions were administered via nasogastric tube either continuously （16 hours/d）, or intermittently （fed during a 90-minute period and followed by a 150-minute pause） for 4 times per day, using an infusion pump. Results There were significant differences in residual gastric volume, gastric pH value, and incidence of nutrition fluid coming into the mouth or the gastric tube between the two groups（P〈0.05 ,P〈0.01）. Conclusion Intermittent enteral nutrition provided by use of a pump can decrease residual gastric volume, lower gastric pH, and reduce incidence of gastro-oesophageal reflux and aspiration. It is an optimal method for providing enteral nutrition to critically ill patients.
