BACKGROUND: Needle thoracostomy (NT) is a frontline intervention for suspected tension pneumothorax in prehospital trauma care. The necessity for intervention in patients with relative indications is unclear, and locoregional protocols guiding NT placement by prehospital personnel vary. This study aims to identify factors associated with a positive response to NT and how often objective measures are utilized to prompt intervention, which may help better define indications for the procedure.
METHODS: A retrospective review of adult trauma patient who received prehospital needle decompression was performed utilizing the trauma registry database from a level 1ACS accredited trauma center in Omaha, Nebraska. A positive response was defined as increased oxygen saturation by 10 %, increased systolic blood pressure by 10 mmHg, improved ventilation or breath sounds, or return of spontaneous circulation.
RESULTS: A total of 214 patients were included, with an overall mortality rate of 52 % of which 144 (68 %) sustained blunt trauma and 67 (32 %) penetrating trauma. Mortality was 49 % for blunt trauma and 60 % for penetrating trauma (p = 0.182). Only 63 patients (30 %) responded to NT with an improvement in clinical parameters. The most common indication(s) for NT was documented as absent/reduced breath sounds (n = 118, 55 %), CPR (n = 79, 37 %), and hypoxia (n = 40, 19 %). After excluding patients with CPR en route (n = 135/214, 63 %), positive NT response increased to 48 % and overall mortality rate decreased to 26 %. There was no significant change in systolic blood pressure (mean difference: 0.3 mm Hg, 95 % CI:4.8-5.3, p = 0.910) or heart rate (-1.1 bpm, 95 % CI:5.8-3.6, p = 0.650) post-decompression. The incidence of hypoxia decreased from 68 % to 48 % (p < 0.001). Complications were identified in 14 % of patients and one patient did have a needle inserted into the heart, required a cardiac operation, and had subsequent anoxic brain injury.
CONCLUSIONS: This study highlights the low success rates of prehospital NT, with the majority of procedures being performed based on subjective indicators. Prehospital protocols should be refined by incorporating objective criteria, such as confirmed hypoxia, to better identify patients who may benefit from NT.
