Drainage and Incisional Negative Pressure Wound Therapy for Intractable Skin Ulcers: A Novel Technique

抄録

With the introduction of the RENASYS TOUCH negative-pressure maintenance and management device (Smith & Nephew plc, London, UK), the treatment of multiple wound sites using Y-connectors has become easier. In addition, the release of drainage accessories has expanded the treatment options. In this study, we combined the RENASYS wound therapy system with drains and incisional negative pressure wound therapy (NPWT) (diNPWT [tentative name]).
The RENASYS TOUCH main unit, Y-connector, foam, and drain accessories were prepared. Conventional drain insertion was replaced by a drain accessory for wound closure after surgical treatment of intractable ulcers. After the drain accessory was placed, the wound was closed, a nonadherent dressing and foam were placed on the sutured wound, and the Y-connector was connected to the main unit. The patient was managed with a negative pressure of −80 to 100 mmHg for 5 to 7 days postoperatively.
The drain accessory used in this study can adjust the pressure according to the instrument itself, and we believe that it can adhere to the lumen with stronger pressure. In addition, by applying NPWT to the sutured wound, postoperative misalignment stress can be avoided, and a good outcome can be obtained.
