Abstract
Negative pressure wound therapy with continuous irrigation is a method of promoting granulation of a wound while controlling infection. In this method, an irrigation tube and an aspiration tube are inserted into a sterile sponge that is attached to the wound surface, and negative pressure is applied to drain fluid. Using this method, we managed postoperative infective open wounds in two cases ; a 67-year-old woman with autologous blood vessel shunt that led to anastomotic rupture due to MRSA infection and an 81-year-old man with complete graft removal due to MRSA infection. Previously, an open wound following vascular access infection required extensive nursing care such as daily irrigation and changes of dressing for months, but in both of these two quite severe cases the infected wounds were easily healed in 4 to 5 weeks using this method. Easily and inexpensively prepared using accessible equipment, this method enables early remission of infection and rapid growth of granulation, and is worth considering as a new treatment for infected wounds in dialysis patients who have unfavorable conditions for wound healing.
