| Description | Aim: The aim of this study was to evaluate the efficiency and effectiveness of two different topical negative pressure devices. In the scientific literature, a number of mechanisms of action associated with NPWT are identified. Secondary effects of NPWT are also accepted for a number of cases and include the reduction of microbial bioburden. However there is currently no explicit evidence available, that this effect can be defined as a major action mode.Thus the question of comparability between different devices and settings is not answered clearly because of the use of different devices as well as differences in application techniques depending on the dressings and wound layers. Method: In the period between January 2008 and December 2012 we observed 70 patients with infected wounds in different locations and indications, who were treated using different NPWT system by a different provider. Data collection was following these defined endpoints.Standard descriptive statistics were applied in the analysis; we used absolute and relative frequencies for categorical variables and median supplemented by 5th and 95th percentile for continuous variables. Results: The length of application of both types of NPWT units – VAC and Vivano – was identical and the results were not statistically significant. No statistically significant differences were found between different treatment regimes. One of the most discussed facts in NPWT using different devices and application systems is the comparability between results attained by using such different systems. According to the results of our retrospective study there is a strong indication that different systems (V.A.C. and Vivano) lead to comparable results. Conclusion: For the treatment of wound healing disorders by different NPWT systems are comparable and there are no statistically significant differences in their effectiveness and efficiency. |
