Cardiac arrest & resuscitation
Diagnostic Yield of CT Imaging and Point-of-Care Ultrasound After In-Hospital Cardiac Arrest
Authors' conclusion
Our results show that among survivors of IHCA, CT imaging and POCUS frequently identified new pathologic features, including suspected arrest causes, with subsequent management changes in a substantial proportion of patients. Chest CT imaging demonstrated particularly high diagnostic yield, whereas POCUS provided timely bedside information.
Study context
- Population
- Adults with in-hospital cardiac arrest (IHCA) who achieved return of spontaneous circulation (ROSC) (excluding out-of-hospital cardiac arrest (OHCA), nonindex arrest, do-not-resuscitate orders)
- Participants
- 112 vs 264
- Exposure
- CT vs point-of-care ultrasound (POCUS)
- CTn = 112
- POCUSn = 264
- Outcome
- New findings and management changes on CT and POCUS imaging
- Follow-up
- Within 48 hours of ROSC
