Abstract
Objective To investigate the value of permissive hypocaloric nutrition support in the treatment of elderly critically ill patients.Methods A total of 126 eligible elderly critically ill patients admitted to Xijing Hospital from January to June 2018 were se-lected as the study subjects.They were divided into standard calorie group,test group A and test group B according to a random number table,42 cases for each group.Patients started early nutritional support within 24 to 48 h of admission.After 7 days,the caloric intake increased to 30 kcal/(kg·d)in the standard calorie group,15 kcal/(kg·d)in test group A,and 9 kcal/(kg·d)in test group B.Nutrition-related parameters(albumin,prealbumin,and nitrogen balance),acute gastrointestinal injury(AGI)grade,sequen-tial organ failure assessment(SOFA)score,complications,and clinical outcomes were compared between the groups.Results After treatment,the nutritional indexes of test group A and test group B were higher than those of standard calorie group(P＜0.05),and the nutritional indexes of test group A were higher than those of the test group B(P＜0.05).The AGI grade score and SOFA score of test group A and test group B were lower than those of the standard calorie group(P＜0.05),and the AGI score and SOFA score of test group A were lower than those of test group B(P＜0.05).The incidence of each complication in test group A was less than that in the standard calorie group and test group B(P＜0.05).The mortality after 2 and 4 weeks of treatment in group A and 4 weeks of treatment in group B were lower than those in the standard calorie group(P＜0.05),and the mortality after 2 and 4 weeks of treatment in group A was lower than that in group B(P＜0.05).Conclusion Allowing low calorie nutrition support has important clinical significance for elderly critically ill patients.Adopting 15 kcal/(kg·d)calorie level can improve the nutritional status of elderly critically ill patients,protect gastrointestinal function,and effectively control complications and mortality.关键词
