Consistent with first-aid guidelines, the action of applying cool running water to a thermal injury is associated with improvements in burn severity and reduced odds of skin grafting in children, study results published in the Annals of Emergency Medicine reports.

Patient data were prospectively collected from a registry comprising pediatric patients who were managed at a tertiary care children’s hospital (n=2,495; median age, 2 years). In a multivariate logistic regression analysis, researchers evaluated the association between adequate first aid (ie, applying cool running water for 20 minutes on a thermal burn within 3 hours of injury) and skin grafting. Other outcomes included in the study were time to re-epithelialization, wound depth, hospital admission, length of stay, and operating room interventions.

Approximately 71.3% of the children (n=1780) who received first aid with running water were given the adequate duration of 20 minutes. Only 9.5% of children (n=236) required grafting, with patients in the adequate first aid group having reduced odds of grafting (odds ratio [OR], 0.6; 95% CI, 0.4-0.8). The adequate duration of water exposure to the burn was associated with a decrease in full-thickness depth of the burn (OR, 0.4; 95% CI, 0.2-0.6), as well as reduced hospital admissions (OR, 0.7; 95% CI, 0.3-0.9) and operating room interventions (OR, 0.7; 95% CI, 0.5-0.9). No changes were observed with hospital length of stay (hazard ratio, 0.9; 95% CI, 0.7-1.2; P =.48).

The single-center design and the reliance on structured interviews to identify which type of first aid (adequate vs inadequate) was given to patients may represent study limitations.

Since the study suggests that cool running water can be of benefit up to 3 hours after a burn, the researchers suggest “out-of-hospital and emergency services should therefore prioritize first aid in the management of all patients who present within this timeframe.”
