ABSTRACT
Objective To study the effect of improved GIF grading intervention program on gastrointestinal dysfunction in critically ill patients.Methods A total of 78 patients with gastrointestinal dysfunction were randomly divided into the experimental group and control group.The patients in the experimental group were treated with modified GIF classification program to evaluate the gravitational status of patients with severe gastrointestinal dysfunction and the control group received routine nursing and treatment.The levels of serum albumin(ALB),nitrogen balance(NB) and total protein(TP) were recorded in two groups,and the feeding rate of the patients was recorded at 24 and 48 hours.The calorie qualifying rate at 7d,duration of mechanical ventilation,ICU length of stay,total length of stay in hospital,ICU mortality,ICU acquired infection rate were recorded.Results Feeding rate at 24h and 48 h,calorie qualifying rate at 7d in the experimental group were significantly higher than those in the controlgroup (P＜0.05);there were significant differences between two groups in TP,NB,and ALB (P＜0.05).Mechanical ventilation duration,ICU length of stay,and total length of stay in hospital were significantly shortened in the experimental group(P＜0.05);there were no significant differences between two groups in ICU mortality and ICU acquired infection rate(P＞0.05).Conclusion The improvement of AGI grading intervention in patients with severe gastrointestinal dysfunction can improve at 24 h,48 h,calorie qualifying rate at 7 d and TP,NB and ALB levels,reduce the time of mechanical ventilation,reduce total length of stay in hospital.
