Effects of percutaneous gastrojejunostomy on nutritional intake and prognosis in severe brain injury patients / 中华急诊医学杂志

ABSTRACT

Objective To evaluate the effects on nutritional intakes and clinical outcomes of severe brain injury patients receiving percutaneous gastrojejunostomy (PEG-J) feedings. Methods The severe brain injury patients treated in ICU of Changshu No.1 Hospital from Jan 2013 to Dec 2016 were enrolled in the study. Patients were randomized into control group, patients received nasoduodenal feedings and treatment group, patients received PEG-J feedings. The feeding speed was adjusted according to the amount of gastric residual or reflux vomiting. The daily dose of enteral nutrition in the first week, endocrine function, immune function, nutritional states and clinical outcomes were recorded. Results Totally 87 patients were enrolled in this study, 45 patients in the control group and 42 patients in the treatment group. The daily dose of enteral nutrition of the treatment group were significantly more than the control group from the fourth to the seventh days (P= 0.001, <0.01, 0.024), the CD4+T-lymphocyte percentage and CD4+/CD8+ ratio were significantly higher in the treatment group on day 7 (P=0.03, 0.01), levels of thyroidstimulating hormone, free triiodothyronine and free thyroxine of the treatment group were higher (P=0.036, 0.013, 0.025), and the level of hormonal was lower in the treatment group (P=0.004).The levels of albumin, prealbumin and insulin dosage were not significantly different between the two groups, neither did mortality, rates of organ failures. But the treatment group has a higher Barthel index scores (P=0.049), shorter length of mechanical ventilation and stay ICU (P=0.044, 0.048), and the lower incidence of vomiting and ventilator associated pneumonia (P=0.013, 0.037). Conclusions PEG-J could increase energy intake, improve immunity and endocrine function, promote the recovery of life ability, reduce the incidence of VAP, shorten mechanical ventilation time and ICU stay in severe brain injury patients.
