AbstractOne hundred twenty-eight cases of chest injury were seen in a Paediatric Trauma Unit over a 5 1/2-year period. One hundred patients sustained motor vehicle accident (MVA)-related blunt chest injuries, 91 of them as pedestrians. Nine children had blunt chest injuries from falls, 10 had stab wounds (3 assault, 7 accidental), and 9 had gunshot injuries (6 from birdshot used by police during civil disturbance). MVA-related injuries were studied separately, as an etiologically homogeneous group. Sixty-five of these patients were under the age of 6. All but 3 also had serious extrathoracic injuries. The mean injury severity score (ISS) in MVA-related injuries was 25. Eight patients died, all with an ISS of 34 or more, 7 of whom had fatal head injuries. In MVA-related injuries, pulmonary contusion (n = 73) was the most frequent lesion seen, followed by rib fracture (n = 62), posttraumatic effusion (n = 58), pneumothorax (n = 38), and pneumatocele (n = 5). In MVA-related injuries, 18 children required ventilation. Thirty-nine (69%) of 56 children with radiologically evident posttraumatic pleural effusion had intercostal chest drainage. Analysis suggests that lung injury is a central event in MVA-related blunt chest trauma. Primary lung injury, radiologically visible as contusion, is complicated by hematoma, posttraumatic effusion, and pneumothorax.
