Negative Pressure Wound Therapy (NPWT)

Historical Milestones

Mark Chariker and Katherine Jeter, and others, publish the results of the treatment of seven patients with incisional and cutaneous fistulae, using a newly devised closed suction wound draining system that incorporated NPWT, the use of moist gauze dressing, a Jackson-Pratt Mini Snyder flat drain, and a transparent adhesive film dressing to seal the wound. The cases were treated from 1984 to 1986 at Spartanburg Regional Medical Center in Spartanburg, South Carolina.

Seven patients with eight fistulae were treated with the system with continuous negative pressures of -60 to -80mmHg. The system was changed every 3-5 days. Six of the fistulae were intestinal, one was renal, and one a lymph fistula. Wounds managed with the system closed in a mean time of 16 days with a range of 8-23 days.

The authors noted that "Critical to the efficacy of our system is the moist gauze packing in the wound." In addition to being an "imperative component" of the suction system, use of the gauze provided the benefits of moist wound healing. The use of the system reduced dressing changes, adding to patient comfort and ease of nursing care. Substantial cost savings were noted from use of gauze versus other conventional dressings, and from staff time savings.
