UNLABELLED: Traumatic shock has been classified as a kind of hypovolemic shock similar to hemorrhagic shock. Since bacterial translocation has been observed in shock, this study investigated the difference in bacterial translocation during traumatic shock and hemorrhagic shock, and considered this effect on lung injury during sepsis.
METHODS: Forty-eight male or female Sprague-Dawley rats were divided into 2 groups, hemorrhagic shock and traumatic shock. Bacterial translocation, endotoxin, and blood gas were evaluated. Alterations of the lungs morphologically and functionally were observed.
RESULTS: Traumatic shock induced more bacterial translocation and endotoxemia from the gut. Blood gas analysis shows a more severe disorder in traumatic shock than in hemorrhagic shock. Pathological morphologic changes of lungs were more severe in traumatic shock than in hemorrhagic shock.
CONCLUSIONS: Traumatic shock cause more bacterial translocation and endotoxemia which subsequently caused serial pathological alterations in lung morphologically and functionally than pure hemorrhagic shock does. These results suggest that this trauma activates more severe mechanism to damage lungs.
