Cardiac arrest & resuscitation
Brain computed tomography after resuscitation from in-hospital cardiac arrest
Authors' conclusion
Although severe edema was less frequent in IHCA relative to OHCA, mild-to-moderate or severe edema occurred in one in three patients after IHCA. Unsuspected neurological etiologies of arrest were rarely discovered by CT scan in IHCA patients.
Study context
- Population
- Patients comatose after resuscitation from in-hospital or out-of-hospital cardiac arrest
- Participants
- 2,306 participants
- Exposure
- In-hospital cardiac arrest (IHCA) vs out-of-hospital cardiac arrest (OHCA)
- IHCAn = 420
- Outcome
- Cerebral edema by grey-to-white ratio (GWR) stratum (no edema ≥1.30, mild-to-moderate <1.30 and >1.20, severe ≤1.20) and newly identified neurological arrest etiology on brain computed tomography (CT)
