Negative pressure wound therapy versus microcurrent electrical stimulation in wound healing in burns.

Objective: To compare the efficacy of negative pressure wound therapy (NPWT) with that of microcurrent electrical stimulation (MES) on wound surface area, length of stay (LoS) and colony count of wounds in patients with burns.

Method: Patients with thermal dermal burn injuries covering 25-40% of total body surface area were enrolled in this clinical trial. Participants were randomly allocated into three, equal-sized groups: patients receiving NPWT, patients receiving MES and a control group which received standard wound care.
