Evaluation of the histopathological effects of salbutamol inhaler treatment in an experimentally induced rat model of pulmonary contusion

Abstract

Background/aim: This study aimed to evaluate the effects of salbutamol inhaler treatment in an experimentally induced model of pulmonary contusion. Materials and methods: Thirty-two male Wistar albino rats were randomly divided into four groups: the control group (CG), sham group (SG), treatment group 1 (TG1), and treatment group 2 (TG2). Experimental contusion was established by targeting the right lung tissue. After 72 h, histopathological evaluation for the severity of edema, hemorrhage, and leukocyte infiltration was performed in both sides of the lungs. Results: Examination of right lung tissues revealed a significant difference in edema, hemorrhage, leukocyte infiltration, and total lung injury scores between the CG and SG. Both TG1 and TG2 had less edema, hemorrhage, and leukocyte infiltration and lower total lung injury scores compared with the SG. There was no significant difference in edema, hemorrhage, and total lung injury scores between the CG and TG1 or TG2. A significant difference in hemorrhage scores between the SG and TG1 and edema scores between the SG and TG2 was observed, with treatment groups having lower values. A significant difference in total lung injury score was also found between SG and TG1. Conclusion: Salbutamol inhaler therapy during pulmonary contusion may prevent complications by reducing edema, hemorrhage, leukocyte infiltration, and total lung injury score.
