Three-part Clinical Question:For diabetic patients with foot ulcers, does the addition of hyperbaric oxygen to standard wound care, result in any acceleration in the reduction of wound size?
Search Terms: diabetes; ulcer; wound care
The Study:Non-blinded concealed randomised controlled trial with intention-to-treat.
The Study Patients: Adult patients with diabetic foot ulcers (Wagner Grade 2 and above), included if a reduction of <30% in wound area. Excluded from trial if transcutaneous <20mmHg and not doubled with 100% oxygen breathing.
Control group (N = 31; 29 analysed): Conventional wound care including wound cleansing, dressing and debridement. Antibiotics if deemed to be infected.
Experimental group (N = 31; 29 analysed): As above plus 100% oxygen breathing at 2.4 ATA for 90 minutes daily to a total of 30 treatments.

Comments:
1. Study not blinded, so a risk of bias despite sealed envelope randomisation.
2. The authors used ANOVA to compare mean differences in wound area within groups over time and concluded reduction in area occurred more quickly with HBOT. They did not compare between group differences.
3. Multiple logisitic regression suggested a DFU patient undergoing standard wound care with HBOT as an adjunctive treatment has nearly 44 times higher odds of achieving a 30% reduction in wound area at completion of 30 days treatment.
4. No outcomes presented at later than day of last HBOT session.
