Paramedic research, 22 April 2026

2 new paramedic and prehospital papers from the 22 April 2026 scan.

• Quantra sonorheometry rules out trauma coagulopathy

  Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine · Cohort · Hypothesis-generating

  Tested whether Quantra can rapidly detect trauma-induced coagulopathy against standard lab tests, and found early Quantra analysis may reliably exclude TIC, but prospective validation is still needed.

• GPT estimates pneumothorax size to guide care

  Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine · Cohort · Hypothesis-generating

  Tested whether a vision-enabled GPT model could estimate pneumothorax size and guide tube thoracostomy vs conservative care, and it matched radiologist measurements closely with good agreement to real-world ED decisions.
