Prehospital point‐of‐care ultrasound in ruptured abdominal aortic aneurysms—a retrospective cohort study
Authors' conclusion
Prehospital POCUS was associated with reduced time to treatment, higher chance of operability and significantly higher 30-day survival in patients with rAAA, ruptured iliac aneurysm or impending rupture of an AAA in this retrospective study.
Study context
- Population
- Patients with ruptured abdominal aortic aneurysm (rAAA), ruptured iliac aneurysm or impending aortic rupture treated by a prehospital critical care physician, Central Denmark Region, 2017–202171 had emergency surgery
- Participants
- 169 patients
- Exposure
- Prehospital point-of-care ultrasound (POCUS) vs no prehospital POCUS
- POCUSn = 124
- NO POCUSn = 45reference
- Outcome
- Overall survival
Main finding
