Abstract

Objective To evaluate the clinical efficacy of hypocaloric enteral nutrition in patients with acute severe traumatic brain injury (TBI). Methods A total of 100 patients with severe TBI [Glasgow Coma Scale (GCS) 3-8 points] were enrolled and randomly divided into hypocaloric enteral nutrition group (hypocaloric group, 41.86-62.79 kJ·kg-1·d-1) and traditional caloric enteral nutrition group (traditional caloric group, 104.65-125.58 kJ·kg-1·d-1), 50 patients per group. The enteral nutrition was given at 24-72 hours postoperatively. The changes of total serum protein (TP), serum-albumin (ALB), plasma hemoglobin (Hb), fasting blood glucose (Glu) and major gastrointestinal tract complications were observed and compared at 7 and 14 days after enteral nutrition support. Results Levels of TP, ALB and Hb were lowered in both groups at 7 and 14 days after nutritional support but showed no statistical difference (P>0.05). Glu was (6.37±1.02)mmol/L in hypocaloric calorie group, significantly lower than (7.35±1.70)mmol/L in traditional caloric group at day 7 after nutritional support (P 0.05), but abdominal distension, diarrhea and stomach retention rate in hypocaloric group were significantly lower than those in traditional caloric group (P<0.05). Conclusion Hypocaloric enteral nutrition can significantly reduce the stress hyperglycemia, abdominal distention, diarrhea, gastric retention and other gastrointestinal symptoms in patients with acute severe TBI. Key words: Craniocerebral trauma; Enteral nutrition; Complications
