Aim:
To evaluate the effects of abdominal trauma on hemorrhagic shock-induced acute lung injury in rats.
Methods:
Five groups were allocated (n = 8) in the study. Group I was taken as the control group, group II as the hemorrhagic shock group, group III as hemorrhagic shock + laparotomy, group IV as hemorrhagic shock + splenectomy and group V as splenectomy + omentectomy + hemorrhagic shock group. Hemorrhagic shock was induced by drawing blood and reducing mean arterial pressure (MAP) to 40 mmHg within 10 min. After a hypotensive period of 1 h, animals were resuscitated. Bronchoalveolar lavage (BAL) was performed to recover cells from the alveolar space with 40 mL of BAL fluid after resuscitation malondialdehyde (MDA) and L-gamma-glutamyl-L-cysteinyl-glycine (GSH) levels were measured in serum, erythrocytes and lung tissue.
Results:
Serum, erythrocyte, lung tissue MDA and GSH levels were significantly increased in hemorrhagic shock groups II-V (P < 0.05). Lymphocyte, neutrophil and alveolar macrophage counts in BAL fluid indicated a significant difference between control and shock groups (P < 0.05).
Conclusion:
The degree of trauma increases hemorrhagic shock-induced acute lung injury.
