An inexpensive method of negative pressure wound therapy for extremities

Negative pressure wound therapy (NPWT) is an established method for the faster wound healing of chronic non‐healing wounds. It is also used for laparostomy wounds and healing of split skin grafts. The commercially available machine and the consumables for NPWT are very expensive and economically not feasible in developing and underdeveloped countries. So, we devised a NPWT system for wounds of the extremity using inexpensive, readily available materials in any hospital. The materials used are sterile glove, autoclaved sponge, Foley catheter, and a wall suction unit. The sponge was placed over the wound, and a sterile glove was pulled over it. A Foley catheter was placed over the sponge and taken out through one of the fingers of the glove. Adhesive plaster was used to air‐seal the glove. The Foley catheter was fixed with silk ties and connected to wall suction. Granulation and wound healing was faster in this system. This system was safe and inexpensive for the treatment of wounds of the extremity.
