The charts of 61 patients treated from 1970 through 1981 were reviewed to
determine the clinical outcome after treatment of air embolism from blunt
(15 patients) and penetrating (21 gunshot and 25 stabbing) thoracic
injuries. The diagnosis of air embolism was confirmed by the presence of
air in the coronary arteries (57%), air aspirated from the heart (30%) or
major artery (10%), or Doppler findings (3%). All patients were in shock or
cardiac arrest, and in 36% of these patients there were early signs of
hemoptysis or unexpected arrest after intubation and positive-pressure
ventilation. Successful management included (1) early thoracotomy for
diagnosis as well as for specific treatment, (2) hilar cross-clamping for
control of bronchovenous communication, (3) maintenance of perfusion
pressures with fluids, vasopressors, or aortic cross-clamping, and (4)
prompt correction of the embolic source, usually a lung resection. The
overall survival rate was 44%, which correlated with the mechanism of
injury, with associated nonthoracic injuries, and with the occurrence of
arrest in a controlled setting. We conclude that (1) air embolism can
insidiously occur even in blunt trauma; (2) suspicion should be high with
hemoptysis or unexpected arrest; and (3) successful treatment includes
immediate thoracotomy for diagnosis, resuscitation, and prompt control of
the bronchovenous communication.
