Experimental thoracoabdominal airgun wounds in a porcine model.

UNLABELLED

The Consumer Product Safety Commission estimates that there are 31,000 airgun injuries annually, 19,000 of which occur in children under 14 years of age. Case reports in the literature include 235 serious and nine lethal pediatric injuries. No experimental model of thoracoabdominal airgun pellet perforation exists. A 60-pound newly killed pig was selected as a model for pediatric airgun injuries. Two commonly available .177-caliber airguns were fired from point blank, 2.5 feet, and 5 feet. A chronograph was used to measure impact velocities for pellets fired at the already-killed pig. Autopsy study of organ wounding was completed. Perforation velocities with point-tip pellets were 407 ft/sec for the thoracic wall and 399 ft/sec for the abdomen. Of the 18 pellets shot at the chest, eight passed through the chest wall, causing 15 organ injuries. Eleven of the 18 pellets perforated the abdominal wall, producing 49 organ injuries.

CONCLUSION

Airguns create serious intracavitary organ injuries in a porcine model. Moreover, ballistic research is possible in unusual surroundings, such as a packing plant.
