Combined hyperbaric oxygen and hypothermia treatment on oxidative stress parameters after spinal cord injury: an experimental study.

BACKGROUND AND AIMS: We undertook this study to investigate the possible beneficial effects of combined hypothermia and hyperbaric oxygen (HBO) treatment in comparison with methylprednisolone in experimental spinal cord injury (SCI). METHODS: Forty eight male Wistar albino rats (200-250 g) were randomized into six groups; A (normothermic control group; only laminectomy), B (normothermic trauma group; laminectomy + spinal trauma), C (normothermic methylprednisolone group; laminectomy + spinal trauma + methylprednisolone treated), D (hypothermia group; laminectomy + spinal trauma + hypothermia treated); E (HBO group; laminectomy + spinal trauma + HBO therapy), F (hypothermia and HBO group; laminectomy + spinal trauma + hypothermia and HBO treated) each containing eight rats. Neurological assessments were performed 24 h after trauma and spinal cord tissue samples had been harvested for both biochemical and histopathological evaluation. RESULTS: After SCI, tissue malondialdehyde (MDA) level of the control group was measured increased, and superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) enzyme activities were measured decreased. In group F, it was also shown that MDA level elevation had been prevented, and group F has increased the antioxidant enzyme activities than the other experimental groups C, D, E (p <0.05). CONCLUSIONS: We concluded that the use of combined hypothermia and HBO treatment might have potential benefits in spinal cord tissue on secondary damage.

Effect of hyperbaric oxygen therapy on the duration of treatment of spinal tuberculosis.

The aim of this retrospective study was to investigate the effect of adjuvant hyperbaric oxygen (HBO) therapy on the duration of antibiotic treatment and rate of radiological improvement in the management of spinal tuberculosis. We reviewed a total of 51 patients with tuberculous spondylitis of the spine who were treated by percutaneous abscess drainage or radical surgical debridement with chemotherapy, and of whom 16 randomly selected patients also received adjuvant HBO therapy and 35 did not. Serological markers were monitored in the course of treatment. Percutaneous needle biopsy was performed on each patient before treatment. Spine and chest radiographs, CT scans and MRI were performed. Infection control was achieved in all patients and no recurrence occured. To our knowledge this is the first reported series of patients with spinal tuberculosis treated with HBO therapy as an adjunct to antituberculous chemotherapy. This combination provided earlier clinical and radiologic improvement than chemotherapy alone.
