Prehospital Simple Thoracostomy Does Not Improve Patient Outcomes Compared to Needle Thoracostomy in Severely Injured Trauma Patients

Background ATLS suggests simple thoracostomy (ST) after failure of needle thoracostomy (NT) in thoracic trauma. Some EMS agencies have adopted ST into their practice. We sought to describe our experience implementing ST in the prehospital setting, hypothesizing that prehospital ST would reduce failure rates and improve outcomes compared to NT. Methods This was a retrospective review of adult trauma patients who received prehospital ST or NT from 2017 to 2020. Results There were 48 patients with 64 procedures included. 83.7% were male and 65.8% injured by penetrating mechanism and of median (IQR) age of 31 (25-46) years. 28 (43.8%) procedures were NT and 36 (56.3%) were ST. Rates of improved patient response (P = .15), noted return of blood/air (P = .19), and return of spontaneous circulation (P = .62) did not differ. On-scene times were higher for ST (16.8 vs 11.5 minutes; P < .02). Overall mortality did not differ between ST and NT (68.2% vs 46.4%, respectively; P = .125). For patients that survived beyond the ED, procedure-related complication rates were 2 of 21 patients (9.5%) in ST and 1 of 12 (8.3%) in NT. In penetrating trauma, simple thoracostomy had longer on-scene time and total prehospital time. Discussion ST did not improve success rates of ROSC and was associated with prolonged prehospital times, especially in penetrating trauma patients. Given the benefit of "scoop and run" in urban penetrating trauma, consideration should be given to direct transport in lieu of ST. Use of ST in blunt trauma should be evaluated prospectively.
