BackgroundTension pneumothorax (TPT) is a frequent life-threat following thoracic injury. Time-critical decompression of the pleural cavity improves survival. However, whilst paramedics utilise needle thoracostomy (NT) and/or finger thoracostomy (FT) in the prehospital setting, the superiority of one technique over the other remains unknown.AimTo determine and compare procedural success, complications and mortality between NT and FT for treatment of a suspected TPT when performed by paramedics.MethodsWe searched four databases (Ovid Medline, PubMed, CINAHL and Embase) from their commencement until 25th August 2020. Studies were included if they analysed patients suffering from a suspected TPT who were treated in the prehospital setting with a NT or FT by paramedics (or local equivalent nonphysicians).ResultsThe search yielded 293 articles after duplicates were removed of which 19 were included for final analysis. Seventeen studies were retrospective (8 cohort; 7 case series; 2 case control) and two were prospective cohort studies. Only one study was comparative, and none were randomised controlled trials. Most studies were conducted in the USA (n=13) and the remaining in Australia (n=4), Switzerland (n=1) and Canada (n=1). Mortality ranged from 12.5% to 79% for NT and 64.7% to 92.9% for FT patients. A higher proportion of complications were reported among patients managed with NT (13.7%) compared to FT (4.8%). We extracted three common themes from the papers of what constituted as a successful pleural decompression; vital signs improvement, successful pleural cavity access and absence of TPT at hospital arrival.ConclusionEvidence surrounding prehospital pleural decompression of a TPT by paramedics is limited. Available literature suggests that both FT and NT are safe for pleural decompression, however both procedures have associated complications. Additional high-quality evidence and comparative studies investigating the outcomes of interest is necessary to determine if and which procedure is superior in the prehospital setting.Copyright © 2021.
