ASSESSMENT ON EFFICACY OF TOPICAL NEGATIVE PRESSURE DRESSINGS AGAINST CONVENTIONAL MOIST DRESSINGS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 26
Abstract
BACKGROUND A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time. Wounds that do not heal within three months are often considered chronic. Recent studies have shown that application of a sub-atmospheric pressure in a controlled manner to the wound site has got an important role in assisting wound healing. The present study was conducted to assess the efficacy of topical negative pressure moist wound dressings as compared to conventional moist wound dressings in improving the healing process in chronic wounds. The aim of this study was to compare the efficacy of topical negative pressure hydrocolloid moist dressing with that of a control group using conventional moist wound dressings in healing of chronic ulcers. MATERIALS AND METHODS This non-randomised controlled trial included 108 patients with chronic wounds, of varying aetiology, admitted in SVRRGGH, Tirupati for a period of one year. The whole sample population was divided into two equal and comparable groups of 54 patients, based on the willingness for undergoing topical negative pressure dressing. Those who were not willing were subjected to conventional moist wound dressings and formed the control group. Selection of patients was done by purposive sampling method. Care was taken so that both the groups had a comparable distribution of patients with regards to age as well as aetiology of the ulcer. RESULTS The mean rate of granulation tissue formation in both the groups were 81.01% (SD= 16.67) of the ulcer surface area for test and 63.96% (SD= 14.58) of ulcer surface area for control. The time to satisfactory healing was also compared and it was 12 days in the test group and 32 days in the control group. The change in the wound surface area was compared and it was 22% in the test group and 9% in the control group. The mean graft take-up in both the groups were 82.57% (SD= 13.78) of ulcer surface area for test and 68.18% (SD= 11.45) of ulcer surface area for control. CONCLUSION In our present study it was concluded that the rate of granulation tissue formation, overall graft survival and patient compliance was better in topical negative pressure dressing group as compared to conventional dressing group. It was also seen that the overall hospital stay and post-operative complications were less in the topical negative pressure dressing group.
