Emergency Department Thoracotomy: A National Trauma Databank analysis

Abstract

Introduction

Emergency Department Thoracotomy (EDT) warrants further investigation in the pediatric population due to concerns about its futility. Our study evaluates how patient demographics, injury characteristics, and physiologic status influence pediatric EDT outcomes in blunt and penetrating trauma.

Methods

This retrospective study analyzed patients ≤19 years who received EDT within 1 hour of arrival to the ED from the National Trauma Data Bank. Cases were stratified by blunt and penetrating trauma. Descriptive statistics and univariate analysis were used to identify predictors of survival post-EDT.

Results

Of the 1,075 pediatric patients who underwent Emergency Department Thoracotomy (EDT), 79.6 % experienced penetrating trauma and 20.4 % blunt trauma, with survival rates at 25.9 % and 9.1 %, respectively. Survivors of penetrating trauma typically presented with more stable vital signs, such as pulse rate, oximetry, and Glasgow Coma Scale (GCS) scores, and lower Injury Severity Scores (ISS), all correlating with survival (p < 0.05). Survivors of blunt trauma were distinguished by higher respiratory rates and temperatures (p < 0.05). Risk factor analysis indicated that age-adjusted bradycardia, age-adjusted hypotension, and pre-hospital cardiac arrest were significant predictors of mortality across trauma types (penetrating trauma: OR = 18.7, 6.2, and 20.7; blunt trauma: OR = 12, 2.69, and 6.4, all p < 0.05). Notably, pre-hospital respiratory support was associated with a reduced risk of mortality for both types of trauma (OR = 0.32 for penetrating, and OR = 0.23 for blunt, p < 0.05).

Conclusions

The study affirms the significance of pre-hospital care, showing that stable vitals and respiratory support enhance pediatric thoracotomy outcomes. Ongoing research into pediatric-specific trauma protocols are needed.
