摘要

Background

Severe burns lead to intense and prolonged systemic inflammation and high rates of organ failure and major complications such as acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and mortality. Although corticosteroids have shown benefits in various critical care settings, no adequately powered randomized controlled trial has yet evaluated their effect in burn patients.

Objectives

The DEXA-BURN trial aims to assess whether early administration of dexamethasone reduces the incidence of major complications (moderate-to-severe ARDS or stage 2–3 AKI) and all-cause mortality in adults with severe burns.

Methods

DEXA-BURN is a multicenter, randomized, placebo-controlled, double-blind trial conducted in 10 French intensive care units. Adult patients with ≥ 20% total body surface area (TBSA) burns, admitted within 24 h of injury and requiring mechanical ventilation, will be randomized (1:1) to receive either dexamethasone (0.2 mg/kg/day IV for 5 days) or placebo. Two endpoints are pre-specified and evaluated using a hierarchical testing strategy: (1) major complications within 28 days (moderate-to-severe ARDS or AKI KDIGO stages ≥ 2); and, if statistically significant, (2) all-cause mortality at day 90. Secondary endpoints include nosocomial infections, ventilator-free days, intensive care unit /hospital stay, CRP trajectory, and steroid-related adverse events. A total of 478 patients will be enrolled. Analyses will follow the intention-to-treat and modified intention-to-treat principle.

Discussion

This trial will provide high-quality evidence on the effectiveness and safety of corticosteroid therapy in the acute management of severely burned patients. Findings may inform future guidelines and improve critical care practices for this understudied population with a high risk of mortality.
