Cardiac arrest & resuscitation
Diagnostic yield, safety, and outcomes of Head-to-pelvis sudden death CT imaging in post arrest care: The CT FIRST cohort study
Authors' conclusion
SDCT scanning early after OHCA resuscitation safely improved the efficiency and diagnostic yield for causes of arrest compared to the standard of care alone.
Study context
- Population
- Patients successfully resuscitated from of hospital circulatory arrest (OHCA) with unknown cause, age >18 years, stable for CT, no known cardiomyopathy or obstructive CAD
- Participants
- 104 vs 143
- Exposure
- Head-to-pelvis sudden death CT (SDCT) added to standard of care vs standard of care (SOC) alone
- SDCTn = 104
- SOCn = 143reference
- Outcome
- SDCT diagnostic yield (causes of arrest identified)
Main finding
As reported in the abstract
Causes of arrest identified
P < 0.001
Observational data: associations, not effects.
Secondary outcomes
Time to diagnosis
reduction 78% · P < 0.0001
- CT use in SOC
- 52% · 74 of 143
Critical diagnoses
- SDCT reduced delayed (>6 hours) identification of critical diagnoses
- 81%; p < 0.001
- Identification of critical diagnoses similar between cohorts
Survival to discharge
- Similar between cohorts
Safety
SDCT safety endpoints incl. AKI
- Safety endpoints, including AKI, similar between cohorts
