It has been applied as adjuvant treatment in many medical conditions over the past 50 years. Different treatment protocols have been proven effective for specifically indicated conditions. To evaluate the clinical effectiveness of Hyperbaric Oxygen (HBO) Therapy as an adjunctive treatment for patients with complex wounds. In this prospective cohort study, 40 patients with complex wounds were included. All patients received HBO. HBO was delivered with 100% oxygen for 90 min at 2.0-2.4 ATA. Wound sizes were assessed by one wound surgeon before, during, and every 2 weeks for a total of 12 months after HBO. An analysis of demographic data, wound size and wound photography was performed. Over the 22-month period ending October 31, 2013, 40 patients (21 men and 19 women) with a mean age of 59.73 (range, 29-88) with complex wounds were included. All complex wounds studied were at least 6 months old. The mean wound size was 16.72 cm² in diameter. Thirty-one patients with complex wounds healed after the completion of a series of HBO treatments (77.5%). Two orocutaneous fistulas were completely closed without further surgery. After 5 HBO treatments, the wound size reduced by 29.7% on average (p = 1.24 × 10^-6). After 10 HBO treatments, the wound size statistically significantly reduced by an additional 16.9% (p = 0.0002). There were no complications in this study. Wound healing process was accelerated by HBO. Significant wound size reduction was noted after 5 HBO treatments. Because the biggest reduction in wound size occurred within the first 10 HBO treatments, it is important to conduct these first treatments without interruption. HBO is an effective and safe treatment modality for complex wounds.
