Safety and Benefits of Intraoperative Enteral Nutrition in Critically Ill Pediatric Burn Patients: A Systematic Review and Pooled Analysis
Bibliographic record
Abstract
Burn injuries significantly increase a patient's metabolic demand. Adequate nutrition is essential as an adjunct to recovery and reducing morbidity and mortality. In contrast to adults, this is especially important for pediatric patients who have limited reserves and are in a period of growth. Burn patients often require multiple anesthetic procedures that are accompanied by standard perioperative fasting periods that result in substantial nutritional interruptions. Continuous intraoperative feeding has been proposed as a solution, but there is no current consensus on its role and safety, particularly in the pediatric population. Thus, the goal of this study was to examine the safety and benefits of intraoperative nutrition in critically ill pediatric burn injured patients. A systematic review of MEDLINE, PubMed, Scopus, and Web of Science was conducted using the following terms: feeding or enteral or nutrition or fasting and adolescent or youth or pediatric or child or teen and burn or thermal injury or fire. The primary outcome was incidence of aspiration. Secondary outcomes included patient nutritional status (caloric deficit and weight), wound healing, days spent in the intensive care unit, ventilator days, pneumonia, number of surgeries, length of hospital stay, and mortality. Pooled analyses of binary outcomes were computed. Four studies consisting of 496 patients, met inclusion criteria. All studies were level IV evidence, but had high methodological quality. The median burn TBSA was 43.8% (interquartile range 33.4%-58.8%), with a median of 30% of patients having an inhalational injury. Patients underwent a median of 4.2 surgeries (interquartile range 1.8-7.4). Intraoperative feeding was conducted through nasoduodenal tubes. There were no aspiration events. Pooled analysis demonstrated that there were no differences in rates of aspiration, pneumonia, or wound infection (P > .05) between patients who were intraoperatively fed and those who were not. Those fed intraoperatively had significantly more surgeries, ventilator days, longer hospital stays, but lower mortality (P < .05). There was large heterogeneity in nutritional assessment methods. Intraoperatively fed patients had an average gain of 144.4 kcal/kg, 1.7 days of exclusive enteral nutrition (vs loss of -119.1 kcal/kg and -1.4 days), and a cumulative positive caloric balance of +2673 kcal ± 2147 (vs loss of -7899 kcal ± 3123) compared to those with interrupted feeding. Continuous intraoperative duodenal feeding during burn surgery appears to be safe in the pediatric burn population, with no reported episodes of aspiration. Uninterrupted feeding was also associated with weight maintenance and reduced caloric deficit. It may also have a survival benefit, as continuously fed patients needed more surgeries and intensive/hospital care, but had decreased mortality.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
