title: Impact of hyperbaric oxygen on diabetic ulcers is unaffected by glycemic control.
abstract: Hyperbaric oxygen (HBO2) therapy is an established intervention for treating chronic diabetic lower extremity ulcers, but the impact of glycemic control on its efficacy has not been determined. The purpose of this study was to evaluate the impact of blood glucose control at initiation of HBO2 treatment on wound healing. Hemoglobin A1c (HbA1c) was measured at start of HBO2 therapy for 22 patients undergoing treatment of chronic lower extremity ulcers at two regional wound care centers. Patients with HbA1c < 7.5% were stratified into a "good glycemic control" group (n = 12, mean HbA1c 6.5 ± 0.8%), and patients with HbA1c ≥ 7.5% were stratified into a "poor glycemic control" group (n = 10, mean HbA1c 8.8 ± 1.4%, p = 0.004 compared to "good glycemic control group"). After 20 HBO2 sessions over 30 days in addition to standard wound care interventions, there was no difference in wound healing between the two glycemic control groups as indicated by. reduction from baseline in ulcer surface area, depth, or volume. The diabetic lower extremity wound response to HBO2 therapy is unaffected by glycemic control prior to treatment, and HBO2 treatment should not be delayed for suboptimal blood glucose control.
