Background: Prior evidence1,2 has suggested that early “pan-scan” after ROSC provides clinically-relevant information that assists in the care of the patient in question, when the cause of OHCA is unclear.
The recent CT FIRST trial looked at patients pre- and post- implementation of a protocol for head-to-pelvis CT within 6 hours of ROSC for adult patients without known cause or evidence of possible cardiac etiology, stable enough for scan. *Patients with GFR <30 were excluded from assignment to CT, although were included in the post/CT cohort if their treating doctors ordered CT scans based on perceived clinical need. To balance this, a similar number of patients with GFR <30 were included in the pre/“standard of care” cohort.
Outcomes After Protocol (Pre- vs. Post-):
Bottom Line: Early pan-CT allows for earlier definitive diagnosis and stabilization without increase in adverse events. While this earlier diagnosis does not seem to yield better survival, earlier stabilization may provide some benefits in terms of resource allocation and disposition, a notable benefit during our current crisis of staffing shortages and ED boarding.
