Haemopericardium and liver laceration associated with airbag deployment

초록

Airbags and seat belts are safety devices in automobiles. First invented in the 1950s, they are now commonplace in most automobiles. However, a seat occupant may sustain unexpected injuries even if the airbag deploys in a car collision. We describe a patient who was suspected of simultaneously sustaining haemopericardium and liver laceration during the "punch out" and "membrane force" phases of airbag deployment. The patient's vital signs stabilised after an emergency pericardiocentesis was performed. In a car accident when high-energy injury is suspected despite airbag deployment, computed tomography of the chest and abdomen or echocardiography should be considered because of the possibility of abdominal solid organ and chest injury.
