Abstract:
Objective To investigate the effects of nutritional therapy under energy metabolic monitoring on nutrition indicators and clinical prognosis of elderly patients with critical severe diseases in the department of Intensive Care Unit (ICU).Methods One hundred and twenty elderly patients admitted to the Department of ICU of Integrate Traditional Chinese Medicine Hospital of Ningbo, from January 2013 to December 2016 were enrolled, and they were divided into a control group (62 cases) and an observation group (58 cases) by randomized block method. The patients in observation group received nutritional support treatment under the guidance of energy metabolic monitoring, the amount of nitrogen needed was measured every day, and appropriate energy was provided according to the amount of nitrogen and the ratio of heat to nitrogen; the patients in the control group were given the nutritional support program according to experience. The clinical efficacy was evaluated after 7 days of treatment in the two groups, the differences in hemoglobin (Hb), serum albumin (Alb), prealbumin (PA), weaning success rate within 7 days, duration of mechanical ventilation, length of stay in ICU, the standard rate of enteral nutrition (EN) in 7 days, parenteral nutrition support rate, reaching EN target calorie time, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score on the 7th day after admission and at discharge, the incidence of complications such as abdominal distention, stress ulcer, ventilator associator pneumonia (VAP), heart failure during nutritional treatment and mortality were observed and compared after EN support between the two groups.Results Compared with control group, after treatment Hb (g/L: 136.5±2.5 vs. 90.4±2.3), Alb (g/L: 35.7±4.6 vs. 32.8±4.2), PA contents (g/L: 211.0±20.8 vs. 190.9±30.7), weaning success rate within 7 days [55.2% (32/58) vs. 33.9% (21/62)], the standard rate of EN in 7 days in the observation group were obviously higher [82.8% (48/58) vs. 51.61% (32/62) allP < 0.05], but duration of mechanical ventilation (days: 8.8±3.5 vs. 11.1±4.0), length of stay in ICU (days: 21.2±5.0 vs. 25.9±6.5), parenteral nutrition support rate [29.3% (17/58) vs. 51.6% (32/62)], reaching EN target calorie time (days: 4.4±2.1 vs. 6.2±2.9), APECHE Ⅱ score 7 days after admission (18.7±5.8 vs. 20.8±8.1), APACHEⅡscore at discharge (13.0±5.2 vs. 15.6±4.5) and the incidence of complications such as abdominal distension [10.3% (6/58) vs. 41.9% (26/62)], stress ulcer [3.4% (2/58) vs. 12.9%(8/62)], VAP [22.4% (13/58) vs. 25.8% (16/62)], heart failure [15.5% (9/58) vs. 24.2% (15/62)] etc, were all lower in observation group (allP < 0.05), and 2 weeks later the mortality was significantly lower in the observation group than that in the control group [13.79% (8/58) vs. 22.58% (14/62),P < 0.05].Conclusions Nitrogen required in elderly patients critically ill patients with early determination, the supply of nutrients to guide empirical method is more accurate compared to the nutritional therapy. Nutritional support under energy metabolism monitoring can shorten clinical course, improve nutritional indicators and help reduce the risk of complications and death.
