机械通气患者肠内营养不同输注方式的比较

Comparison of Different Enteral Nutrition Infusion Ways

探讨机械通气患者肠内营养时最佳输注方式及应用时机。选择30例进行机械通气的患者,采用3种输注方式:间歇泵入输注(90min/次,5次/d)、持续泵入输注20h、持续泵入输注14h;每4h监测1次患者胃液残留量及胃液pH值,每种输注方式观察24h。结果3种输注方式下抽取的胃液残留量及测得的胃液pH值差异均有统计学意义(P<0.05)。间歇泵入输注方式较持续泵入输注14h、持续泵入输注20h测得的胃液pH值低,胃液残留量少,机械通气患者早期肠内营养适应后,更适宜采用此输注方式。

To explore the best nasal feeding method in the mechanical ventilation patients and the application time. Select the 30 patients with mechanical ventilation, There different infusion ways were used, intermittent infusion way（90 min/ time, 5 times）, continuous infusion（ 20-hour／14-hour）, using enteral feeding pump, Siphoning gastric residual juice every 4 hours, inspecting gastric juice pH value every 4 hours, monitoring 24 hours. The differences between the three infusions of extracted gastric residual volume and gastric juice pH value were statistically significant （P〈0.05）. Gastric residual volumes in intermittent feeding regimen was lower than continuous feeding regimen（20H. 14H ） ; Gastric juice PH in intermittent feeding regimen was lower than continuous feeding regimen（20H,14H）. After having adapted to early enteral nutrition patients with mechanical ventilation use intermittent feeding re~：imen preferably.
