The Effects of Hyperbaric Oxygen Therapy on Bone Distant From Sites of Surgery.

摘要

Background: Hyperbaric Oxygen Therapy (HBOT) is used to promote soft and hard tissue repair at sites of injury or disease. It is not known whether it has any effect on uninjured tissues. Objective: To evaluate the effect of HBO on vertebral bones distant from a calvarial surgical site. Materials and Methods: 22 male New Zealand white rabbits were divided into two groups (n=11). All animals underwent surgery to produce bilateral calvarial critical sized defects. Group 1 received HBOT while Group 2 served as controls breathing room air (NBO). The Marx HBO protocol was used (90min, 100% oxygen at 2.4 ATA, 5 days a week for 4 weeks). Subjects were sacrificed at 6 weeks. The vertebrae were analyzed by micro-CT (muCT) and histology. Results: There were no statistical significant differences between the two groups. Conclusion: we concluded that there were no harmful effects of HBOT on non-injured vertebrae at 6 weeks.
