After gun-shot wound with high velocity steel-ball pellet was inflicted of one hind limb ofthe pigs, the changes of hemodynamics, blood gases, chest x-ray films, serum T3 and T4,fibronectin, protein content of lung lavage, lung weight, etc were observed within the 72-hour-peri-od postinjury or when the animal was killed or died 72 h postinjury. The pathological changes wereexamined as soon as possible with both optic and electron microscope. Changes of the above-men-tioned parameters in different intensity were found especially in those animals which diedspontaneously. In addition, the relationship between the occurrence of respiratory distresssyndrome(RDS) after trauma and the trauma index-injury severity score was discussed and it waspointed out that attention should be paid to the subclinical type of RDS.
