概要

 These medical articles examine contemporary strategies for improving the clinical management and prognosis of severe burn injuries. Research into nutritional interventions reveals that supplemental enteral glutamine does not significantly reduce mortality or shorten hospital stays despite its common use. Fluid resuscitation studies highlight the ongoing debate between using crystalloids alone versus adding albumin, suggesting that while albumin may improve fluid balance, its impact on survival requires further randomized controlled testing. Beyond treatment protocols, the sources emphasize the importance of patient-specific risk factors, such as using the Modified Frailty Index to predict death more accurately than traditional age-based metrics. Finally, the evaluation of bronchoscopic scoring systems indicates that the Inhalation Injury Severity Score serves as a vital independent predictor of survival for patients with smoke-induced lung damage. Together, these findings aim to refine resuscitation standards and enhance the accuracy of prognostic tools in burn centers. A Randomized Trial of Enteral Glutamine for Treatment of Burn Injuries.

Comprehensive Study Guide: Critical Advances in Burn Resuscitation and Clinical Prognostication This study guide synthesizes key research findings regarding nutrition, resuscitation fluid choices, frailty assessment, and inhalation injury scoring in the management of severe burn injuries. I. Enteral Glutamine Supplementation: The RE-ENERGIZE Trial The RE-ENERGIZE trial addressed the clinical uncertainty regarding the benefits of glutamine supplementation for patients with severe burns, who experience significant inflammation and metabolic stress. Study Overview Purpose: To determine if enterally delivered glutamine reduces the time to discharge alive from the hospital or impacts mortality.Design: A multicenter, double-blind, randomized, placebo-controlled trial conducted across 54 burn centers in 14 countries.Participants: 1,200 patients with deep second- or third-degree burns (typically ≥10% to ≥20% Total Body Surface Area [TBSA] depending on age).Intervention: 0.5 g per kilogram of body weight per day of enteral glutamine versus a non-isonitrogenous placebo, administered every four hours via feeding tube or mouth.Duration: Treatment continued until seven days after the last skin grafting procedure, discharge from the acute care unit, or three months post-admission. Key Results Primary Outcome (Time to Discharge Alive): There was no significant difference between groups. The median time to discharge was 40 days for the glutamine group and 38 days for the placebo group.Mortality: Six-month mortality rates were similar, at 17.2% in the glutamine group and 16.2% in the placebo group.Tertiary Outcomes: No significant differences were found in in-hospital mortality, gram-negative bacteremia, or length of stay.Safety: While glutamine was associated with small increases in urea levels, it did not increase the incidence of acute kidney injury (AKI) or the need for renal replacement therapy. Serious adverse events were similar across both groups. Conclusion Supplemental enteral glutamine does not decrease mortality or reduce the time to discharge alive for patients sustaining severe burn injuries. II. Burn Resuscitation Practices: The ABRUPT Studies The Acute Burn ResUscitation Multicenter Prospective Trial (ABRUPT) examined the historical controversy regarding whether to use crystalloids alone or adjunctive colloids (specifically albumin) during the first 48 hours of burn shock. ABRUPT (Observational Study) Objective: To characterize current resuscitation practices in North America to design future randomized trials.Findings: Two-thirds of patients (253 of 379) were resuscitated with a combination of albumin and ...
