- Up to one-third of trauma patients experiencing cardiac arrest shortly after emergency department (ED) arrival survive to discharge.
- Authors: these patients “warrant an aggressive approach.”
Why this matters
- Field CPR due to trauma portends a dismal prognosis.
- Few data address prognosis of trauma patients whose cardiac arrest occurs shortly after hospital arrival.
- Survival with blunt injuries:
- CPR commencing 1-60 minutes after arrival, across Injury Severity Scores (ISS): 8.5%-10.2% (P>.05);
- CPR commencing 61-120 minutes after arrival, ISS 25: 36.1% vs 8.7% (P<.00003>
- Survival with penetrating injuries:
- CPR at 1-60 minutes, across ISS: 4.3%-6.8% (P>.05);
- CPR at 61-120 minutes, ISS 25: 36.4% vs 9.1%.
- Retrospective study of American College of Surgeons' National Trauma Data Bank Research Data Set.
- Researchers assessed 9365 trauma patients who had field vital signs but required CPR commencing between 1 and 120 minutes after hospital arrival.
- Outcome: survival to discharge.
- Funding: None.
- Patient ages not specified.
- Few survivors in some subsets, and 95% confidence intervals not provided, so precision of estimates is unclear.
- Details on arrest etiology not available.
