Effect of lowering the temperature of enteral nutrition on prevention of stress ulcer in patients with severe craniocerebral injury / 中国实用护理杂志

ABSTRACT

Objective To probe into the efficacy and safety of lowering the temperatures of enteral nutrition in severe craniocerebral injury patients to prevent stress ulcer,and provide reference for patients with severe craniocerebral injury to choose appropriate enteral nutrition temperature. Methods The clinical randomized controlled trial was adopted.Numbered the patients by the order of being hospitalized, then divided the 84 patients with severe craniocerebral injury who were receiving enteral nutrition into experimental group and control group with 42 cases each.The constant temperature in experimental group was 22 ℃, and that in control group was 38 ℃. Observed and compared regularly the pH levels, occult blood test of gastric juice and defecate of the two groups within 7 days. Results After different temperature enteral nutrition,pH value of gastric juice of patients at 1,4,7 days after enteral nutrition was 2.610.37,4.550.35,4.870.34 in experimental group,2.210.44,3.930.22,4.180.30 in control group,there was significant difference between two groups (t=3.856, 8.185, 8.322, all P<0.01). There was no significant difference between two groups in the positive rate of gastric occult blood test(x2=0.102,0.408, 1.332, all P>0.05). There was no significant difference in the incidence of diarrhea and diarrhea start time between two groups (x2=0.288, t=0.372, all P>0.05). Conclusions Lowering the temperature of enteral nutrition has a certain protective effect on the gastric mucosa of patients with severe craniocerebral injury,which is helpful to prevent the occurrence of stress ulcer,and does not increase the risk of diarrhea.
