Cardiac arrest & resuscitation
Lung parenchymal and pleural findings on computed tomography after out-of-hospital cardiac arrest
Authors' conclusion
Over three-quarters of patients who survived to the hospital post OHCA and received a chest CT had lung parenchymal or pleural abnormalities, the most common of which were aspiration, pulmonary edema, and consolidation/pneumonia.
Study context
- Population
- Adults resuscitated from out-of-hospital cardiac arrest (OHCA) with return of spontaneous circulation (ROSC) who underwent head-to-pelvis or dedicated chest computed tomography (CT), 2014–2019
- Participants
- 204 eligible patients
- Outcome
- Incidence of lung parenchymal and pleural abnormalities on CT (composite)
Methodological detailstwo academic hospitals
- Two academic hospitals
Main finding
As reported in the abstract
Abnormal lung parenchyma or pleural findings
Patients with abnormal lung parenchyma or pleural findings
160
78 %
Observational data: associations, not effects.
Further findings
Association of CPR duration and time to successful intubation with abnormal lung findings
- Longer CPR duration or longer time to successful intubation associated with higher incidence of abnormal lung findings on CT
- Multivariable analyses
Time from 911 call to CT scan
- Median time from 911 call to CT, hours (IQR 2.0-3.4)
- 2.5
