Therapeutic effect of continuous diffusion of oxygen therapy combined with traditional moist wound dressing therapy in the treatment of diabetic foot ulcers

To investigate the therapeutic effect of continuous diffusion of oxygen (CDO) combined with traditional moist wound dressing (MWD) on the diabetic foot ulcers (DFUs) inpatients. The inpatients from May 2016 to April 2018 were enrolled and randomly divided into MWD, CDO and combination treatment groups (n = 40 each group). The moist dressing was used in the MWD group while a micro-oxygen supply device was used in the CDO group. The combination treatment group was given both MWD and CDO. All patients were treated for 8 weeks. The wound healing, amputation rate, and inflammatory control were evaluated. Compared with MWD and CDO groups, the combination group showed a higher wound healing rate (P
