  • Title: Early pulmonary embolism after injury: a different clinical entity?
    Author: Benns M, Reilly P, Kim P.
    Journal: Injury; 2014 Jan; 45(1):241-4. PubMed ID: 23518042.
    Abstract:
    BACKGROUND: We sought to characterize pulmonary embolism (PE) occurring early after injury. We hypothesized that early PE may represent a different clinical entity than those occurring later in the post-injury period. METHODS: All trauma patients diagnosed with PE from 2005 to 2010 were examined. PEs diagnosed within 72h of admission were compared against those occurring later. RESULTS: 19 out of 54 PEs were diagnosed early. Early PE patients had a higher rate of lower extremity fractures, a lower mean injury severity score, and a lower average length of stay. Early PE patients had a shorter average time to start of chemical prophylaxis, were less likely to have had a femoral line, and less likely to have operative intervention under general anaesthesia. CONCLUSIONS: Early PE after trauma may occur with different underlying pathophysiology than previously thought. Further study is indicated as this has implications concerning the prevention of PE in trauma patients.
