Özet
Aim: In this study we aimed to in vestigate the protective effects of L-Arginine on cardio-respiratory complications in a diaphragmatig rupture model. Method: 40 Sprague-Dawley rats were used in this study. In Group I, only thoracotomy was performed. In Group II, III and IV, following left thoracotomy, the stomach was pulled into thorax and the intraabdominal pressure was increased by an insufflator. L-Arginine (L-Arg) was given in GIII and L-NAME was given in GIV at the 45th minute of the study, The parameters such as arterial blood pressure (BP), heart rate (HR), arterial blood gases analysis (pO2, pCO2, pH) and pulmonary scintigraphy were measured at the baseline, 30th, 45th and 60th minutes of the study. The left lungs were extracted for histopathological examination. Results: In the values of blood gases analysis following the performing herniation model the pO2 and pH values decreased and pCO2 values increased in GII in comparison with GI. The mean values of blood gases analysis in GIII following L-Arg infusion at the 60th minute of the study were found to be increased for pO2 and pH values and to be decreased for pCO2 values in comparison with the values of GII. Following L-NAME administration to the GIV, there was no difference found between GII and GIV. Pulmonary uptake decreased in GII, GIII and GIV when compared with GI, whereas pulmonary uptake in GIII was significantly increased in comparison with GII and GIV. Conclusion: The use of the precursor of nitric oxide, L-Arginine, may provide protective effects on cardio-respiratory complications related to organ herniation in the acute period of traumatic diaphragmatic rupture.
