چکیده مقاله

Objective:

Diabetic foot ulcers (DFU) are often hard-to-heal, despite standard care. With such a complicated healing process, any advanced wound care to aid healing is recommended. Chitosan/collagen composite hydrogel materials have the potential to promote the regenerative process. In this study, the efficacy of a new collagen matrix dressing including chitosan/collagen hydrogel was compared with a standard dressing of saline-moistened gauze for wound healing in patients with a hard-to-heal neuropathic DFU.

Method:

This is an open labelled, randomised clinical trial. After conventional therapy consisting of debridement, infection control and offloading, patients were randomly allocated to receive either a collagen matrix dressing (the study group, receiving Tebaderm manufacturer) or a saline-moistened gauze dressing (control group) for wound care. The reduction in DFU size and the number of patients with complete healing were measured throughout the treatment and in follow-up.

Results:

A total of 61 patients with a neuropathic DFU were recruited. Average percentage reduction in DFU size at four weeks was greater in the study group compared with the control group (54.5% versus 38.8%, respectively). Rate of complete healing rate at 20-weeks' follow-up was significantly better in the study group than the control group (60% versus 35.5%, respectively).

Conclusion:

The collagen matrix dressing used in this study accelerated the healing process of patients with a hard-to-heal DFU. Further research may suggest the used of this dressing to shorten the length of time to achieve complete healing
