RESUMO
Objective Under 2 methods of guidance: indirect energy metabolism measurement and classical Harris-Benedict (HB) formula to carry out enteral nutritional support program to observe the difference in influence on nutritional status and prognosis of the patients. Methods Sixty patients with critical coma admitted to the Department of Critical Care Medicine of the 903rd Hospital of PLA from November 2015 to April 2017 were enrolled, and they were divided into a metabolic vehicle group (30 cases) and a formula group (30 cases) according to the random number digital table. All the patients were treated with stage nutritional therapy according to the daily energy consumption, which was measured by indirect energy metabolism measurement or HB formula. The change of serum albulmin (Alb), blood hemoglobin (Hb) and peripheral blood total lymphocyte count (TLC) before treatment and after 1 week and 2 weeks of nutritional support and the incidence of complications and prognosis after 2 weeks of nutritional support were observed; the difference of mid-upper arm circumference (MAC) was compared between before nutritional support. Results After the nutrritional therapy, serum Alb, Hb, and TLC in two groups were obviously higher than those before treatment, the degrees of elevation in metabolic group were more significant than those in the formula group [Alb (g/L): 36.34±4.09 vs. 35.26±3.82; Hb (g/L): 131.6±13.8 vs. 128.8±12.6; TLC (×109/L): 1.63±0.51 vs. 1.50±0.48, all P < 0.05]. The incidence of complications and mortality of the patients in metabolic vehicle group were lower than those of the formula group [40.0% (12/30) vs. 56.7% (17/30), 13.3% (4/30) vs. 16.7% (5/30) respectively, both P < 0.05]. After 2 weeks of nutrition support, the MAC of both groups increased compared with that before treatment, but there was no statistical significant difference in MAC in two groups (all P > 0.05). Conclusion Compared with the HB formula, the metabolic vehicle method can guide the daily energy intake of patients with severe coma more accurately. It is worthy to promote nutrition support program clinically guided by the metabolic vehicle one.
RESUMO
Objective To evaluate the effect of indwelling nasointestinal tube for enteral nutrition (EN) support on patients with severe craniocerebral trauma undergoing mechanical ventilation (MV). Methods A total of 100 severe craniocerebral trauma patients undergoing MV admitted to intensive care unit (ICU) of the 117th Hospital of People's Liberation Army from February 2015 to February 2017 were enrolled, and they were divided into nasogastric tube group in which the EN was fed by nasogastric tube and nasal jejunal feeding tube group (nasointestinal tube group) by random digits table, with 50 patients in each group. Blood urea nitrogen (BUN), hemoglobin (Hb), serum albumin (Alb), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score, Glasgow coma scale (GCS) score before and 10 days after treatment, duration of MV, hospitalization time, and the incidences of ventilator-associated pneumonia (VAP) and reflux wrong aspiration of the two groups were observed and compared. Results There was no statistically significant difference in BUN, Hb, Alb, APACHEⅡscore or GCS score before treatment between the two groups. Ten days after treatment, BUN and APACHEⅡ score in the nasointestinal tube group were significantly lower than those in the nasogastric tube group [BUN (mmol/L): 6.3±1.6 vs. 8.0±2.2, APACHEⅡscore: 17.9±3.2 vs. 20.8±6.3, both P < 0.05], Hb, Alb, GCS score were significantly higher than those in nasogastric tube group [Hb (g/L): 125.9±19.7 vs. 113.5±19.6, Alb (g/L): 35.9±6.2 vs. 31.9±6.2, GCS score: 9.7±1.9 vs. 8.2±5.7, all P < 0.05], duration of MV and hospitalization time were significantly less than those in the nasogastric tube group [duration of MV (days):14.7±3.4 vs. 17.5±2.9, hospitalization time (days): 15.4±5.6 vs. 19.2±7.3, both P < 0.05], and the complication rate in nasointestinal tube group was obviously lower than that in nasogastric tube group [10% (5/50) vs. 36% (18/50), P < 0.05]. Conclusion For patients with severe craniocerebral trauma treated with MV, the EN treatment by means of indwelling nasointestinal tube is helpful for the recovery of consciousness, improvement of nutritional indexes, reduction of incidences of complications such as reflux aspiration, etc. and shortening the course of disease, thus the method can obviously improve the patients quality of life.
