The use of hyperbaric oxygen therapy in the care of the diabetic patient with nonhealing ulcers, refractory osteomyelitis, or both of the lower extremity can be a valuable adjunct in their overall treatment. Adequate tissue oxygenation to promote wound healing and stimulate cellular defenses can be achieved in a hyperbaric environment. Several clinical studies have supported its use in select patients.
"The technique may be implemented in a walk-in multiplace chamber compressed to depth with air while the person breathes 100% oxygen via head tent, face mask, or endotracheal tube. Multiplace chambers accommodate up to six patients at a time; each patient is given an individual breathing source.13 Alternatively the patient may be treated in one person monoplace chamber pressurized to depth with oxygen.

[Show abstract][Hide abstract] ABSTRACT: THIS STUDY AIMS TO COMPARE THE EFFICACY OF ANTISEPTIC DRESSINGS, HYPERBARIC OXYGEN THERAPY, AND RECOMBINANT HUMAN PLATELET DERIVED GROWTH FACTOR (RHPDGF) FOR TWO REASONS: i) to reduce the incidence of lower limb amputations in diabetic foot ulcer; ii) to limit the duration of stay in the hospital. A prospective randomized trial was conducted on 60 patients with stage III and IV diabetic foot ulcers (International Association of Enterostomal Therapy classification) and patients were divided randomly in three different therapy groups - antiseptics, hyperbaric oxygen therapy, recombinant platelet derived growth factor, with 20 patients in each group. Patients were managed initially on inpatient and then on outpatient basis till the ulcer healed completely. Results among three groups were compared using unpaired T test and the level of significance was set at P<0.05 using ANOVA. This study compares the efficacy of hyperbaric oxygen therapy, antiseptic dressings, and rhPDGF in grade III and IV diabetic foot ulcers. P value (0.0348) was significant for complete wound contraction while p value healing time (0.6534) and ulcer size (0.0593) in the groups was not significant. PDGF is safe, effective and easy to apply. Results are comparable with hyperbaric oxygen (HBO) therapy and cost of treatment is lower than other therapies. Diabetic foot ulcer management requires multidisciplinary and aggressive approach. PDGF should be recommended for all grade III and IV diabetic foot ulcer at least 8 weeks old. HBO is equally good an option but has limitations and side effects.
[Show abstract][Hide abstract] ABSTRACT: Perineal involvement in Crohn's disease is a common and distressing condition, often refractory to medical or surgical treatments. Recent reports suggest the efficacy of hyperbaric oxygenation (HBO) in the healing of perineal lesions. We evaluated HBO in severe patients with perineal Crohn's disease.
Ten consecutive patients (8 women, 2 men; mean age, 30 years) were studied. There were four superficial fissures, four cavitating ulcers, six low or superficial fistulas, two high fistulas, and one irreversible anal stenosis. All patients had received one or more medical treatments without healing the perineal lesions, and all had had previous surgery for perineal lesions.
Two patients discontinued HBO after a few sessions and did not complete treatment. Eight patients completed at least 30 HBO sessions and were evaluable. At the end of the procedure, six of eight patients treated were healed, three completely and three partially. All patients who healed completely received HBO as an additional treatment to local perineal surgery.
HBO might be useful as a last resort treatment of chronic perineal Crohn's disease, resistant to other treatments or as a complement to surgery.

[Show abstract][Hide abstract] ABSTRACT: This study sought to determine whether infrapopliteal transcatheter interventions can salvage ischemic limbs in diabetic patients referred for below the knee amputation at our institution.
The value of transcatheter interventions in diabetic crural arteries is controversial. Tissue oxygen partial pressure (TCO2) levels < 40 mm Hg predict poor wound healing.
Percutaneous interventions were performed in 29 consecutive diabetic patients in need of limb salvage. Technical success was defined as < 20% residual vessel stenosis. Clinical success was defined as the avoidance of amputation and achievement of wound healing. At hospital discharge, patients were treated with Coumadin and aspirin. Ankle-brachial index (ABI) and TCO2 measurements were obtained before and after the intervention.
After 12-month follow-up, six patients had presistent wounds, whereas 23 experienced wound healing. Forty of the 50 infrapopliteal arteries successfully dilated were occluded, with a mean (+/-SD) lesion length of 18.0 +/- 3.5 cm. After the procedure, TCO2 improved from 27.82 +/- 9.97 mm Hg (95% confidence interval [CI] 23.95 to 31.69) to 54.5 +/- 14.73 mm Hg (95% CI 48.79 to 60.21, p < 0.0001), whereas the ABI did not (p > 0.2). TCO2 predicted procedural and clinical success (p < 0.0182).
Infrapopliteal transcatheter interventions in diabetic patients may salvage the majority of limbs doomed to amputation. Although TCO2 measurements are valuable in predicting wound healing and success after interventions, ABI measurements are not.
