| Zusammenfassung: | OBJECTIVE: To explore the pathomorphological changes in abdominal viscerae injuries produced by underwater blast waves METHODS: Sixty-one adult mongrel dogs were used in this study. Underwater explosions in different intensity were produced by detonating 200 g, 500 g and 1,000 g TNT, respectively. The physical parameters of blast wave were measured by PCB dynamic pressure transducers specially designed for underwater explosion. The pathomorphological changes in abdominal viscerae were observed at 6 hours after injury RESULTS: The physical features of underwater blast wave were characterized by high peak pressure, short positive action duration, and higher intensity of impulse. The pathomorphological observation revealed high incidence of injuries of gastrointestinal tract (62.30 percent), manifesting mainly various degrees of subserosal and submucous bleeding in gastrointestinal tract. Rupture of seromuscular layer, subserosal hematoma, and even, perforations of gastrointestinal tract occurred in some animals. Injuries of the liver, spleen, pancreas and other parenchymatous organs injuries, such as subcapsular bleeding, hematoma, and ruptures, appeared with low incidence. No obvious injuries were found in the gallbladder or urinary bladder and other fluid containing organs CONCLUSION: Underwater blast wave can induce injuries to many abdominal viscerae. Gastrointestinal tract injuries, occurring in high incidence are usually severe, and they should be given early treatment in underwater blast injuries |
