Nano-colloidal silver and chitosan bioactive wound dressings in managing diabetic foot ulcers: case series

J Wound Care. 2018 Sep 1;27(Sup9a):S32-S36. doi: 10.12968/jowc.2018.27.Sup9a.S32.


Objective: To study the effectiveness of nano-colloidal silver and chitosan bioactive wound dressings in the treatment of diabetic foot ulcers (DFU).

Method: Patients with DFUs were selected randomly. Wound size, appearance and presence of infection were recorded at each dressing change.

Results: We assessed five patients in this case series. The use of both nano-colloidal silver and chitosan biopolymer dressings aided wound healing. The patients did not require surgical debridement or amputation. All five cases in this study had a slow healing rate at presentation.

Conclusion: Applications of nano-colloidal silver in conjunction with chitosan bioactive as primary dressings in managing DFUs cases are safe and help increase wound healing rates, thus, leading to significant cost savings in the hospital setting.

Keywords: chitosan-based dressing; diabetic foot ulcers; nano-colloidal silver.
