Abstract

 

OBJECTIVES: We aim to histopathologically analyze the effect of hyperbaric oxygen (HBO) therapy in the lung tissue.

 

MATERIAL AND METHODS: A total of 21 rabbits were divided into three groups, with each containing seven rabbits. Group 1 was the control group. Group 2 underwent HBO of 3 atmosphere absolute (ATA) for 90 min/day for 7 days. In group 3, HBO at 3 ATA was administered 90 min/day for 28 days. Oxygen saturation (SpO2) was determined by pulse oximetry before and after administration of HBO. Rabbits were sacrificed, and the apex of the right lung was excised.

 

RESULTS: SpO2 was 98-100% in all rabbits before HBO administration. After the procedure, the mean SpO2 was 92% and 83% in groups 2 and 3, respectively. As expected, histopathologic examination in group 1 was normal. In group 2, congestion in the lung vessels, mononuclear cell infiltration in the bronchial mucosa, interstitial edema, and alveolar dilation were evident. Histopathologic examination in group 3 indicated diffuse alveolar edema, peribronchial mononuclear cell infiltration, thickening of the alveolar and vessel wall, and intraalveolar hemorrhage.

 

CONCLUSION: There is a strict relationship between duration of HBO administration and severity of lung injury.
