| Objective:The purpose of this study is to explore the effect of three different pump methods of three unit intermittent nasal feeding on the patients with mechanical ventilation in ICU,and to provide reference for the selection of reasonable nutritional methods for such patients.Methods:From May 2018 to January 2019,120 patients with mechanical ventilation who were admitted to the intensive care unit of our hospital were given enteral nutrition 24 hours after admission.According to the random digital method,120 patients were randomly divided into three groups: group A(continuous 6h interval 2h pump group),group B(continuous 5h interval 3h pump group)and group C(continuous 4h interval 4h pump group).Each group was 40 patients.Three groups of patients in the main prognostic indicators of ventilator associated pneumonia(VAP),gastric retention,gastric juice p H value,nutritional status and blood glucose index differences,the observation results were analyzed by SPSS 20 statistical software.Results:1 VAP occurrence:The incidence of VAP in group A,B and C was 5.0%,2.5% and 22.5% respectively.The incidence of VAP in the three groups was statistically significant(P < 0.05).The incidence of VAP in group C was significantly higher than that in group A and B(P < 0.017).But there was no significant difference between group A and group B(P > 0.017).2 Gastric retention and gastric juice p H: the incidence of gastric retention in group A?group B and group C was 10%?7.5% and 30% respectively,and the p H value of gastric juice was 2.63±1.01?2.25±0.94?4.31±1.73?There was significant difference between the three groups in the incidence of gastric retention and gastric juice PH(P<0.05).Comparison between the three groups,the incidence of gastric retention and gastric juice PH in group C were significantly higher than those in group A and B,and the differences were statistically significant(P<0.017).But there was no significant difference between group A and group B(P > 0.017).3 Nutritional status: there was no significant difference between the three groups(P > 0.05).4 Blood glucose: the fluctuation range of blood glucose in three groups before and after feeding was 1.38±0.67mmol/L ? 1.42±0.83mmol/L and 1.57±0.54mmol/L,respectively.There was no significant difference between the three groups(P > 0.05).Conclusion:1 The incidence of VAP in 6-hour interval 2 hours and 5-hour interval 3 hours was significantly lower than that in 4-hour interval 4 hours.2 Continuous 6h interval 2h infusion mode and continuous 5h interval 3h infusion mode were significantly better than continuous 4h interval 4h pump in reducing gastric retention and maintaining gastric juice PH.3 The effect of nasal feeding and pump infusion on maintaining nutritional status of ICU patients was basically the same.4 With the increase of nasal feeding pump speed,there was no significant effect on blood glucose,but they all showed an upward trend.During enteral nutrition,clinical medical staff should pay attention to monitoring blood glucose,and be alert to the occurrence of hyperglycemia.5 On the basis of continuous 6h interval 2h intermittent three unit nasal feeding infusion,the time of suspension of nasal feeding pump can be extended to 3h,which can reduce the incidence of VAP and gastric retention and maintain normal gastric juice p H value,and has no obvious effect on blood glucose.In addition,this pumping method is consistent with our daily eating habits of three meals.The pause time of enteral nutrition is extended from 2 hours to 3 hours to give the gastrointestinal tract more rest time,which is more conducive to the digestion of patients.This method has clinical application value. |
