The cause of delayed partial-thickness burns healing after ussing wound covers

Abstract

It was analyzed the terms of healing of partial-thickness burns and the results of 490 microbiological samples from the surface of wounds from 215 patients. All patients underwent tangential necrectomy (dermabrasion) on days 2-3 after the burn. To close the postoperative wound, wound coverage based on hyaluronic acid, n=61, and atraumatic dressings Voskopran, n=154 were used. During bacteriological examination, the degree of microbial contamination, the type of pathogen and sensitivity to antibacterial drugs were determined, special attention was paid to MRSA, MRSE, VRE, FQRPA, CRKP, CRA, CRE. The results are processed statistically. According to the results of the study, it was found that the average healing time for partial-thickness burns was 22,9±1,7 days, in 33,5 % (n=72) of observations, there was a delayed wound healing, more than 21 days. In patients in whose local treatment GBM was used, in 90,2 % (n=55) of cases, burns healed within 21 days, and where AP was used only in 57,1 % (n = 88) of patients, burn wounds healed in the specified terms. In the group of patients with delayed healing of burns, the microorganisms with high growth (CFU> 105 / ml) was 2,5 times higher than in patients with wound healing within 21 days. Comparing the microbial landscape in the groups, it was found that in the group with delayed healing of burns, resistant microorganisms of the ESKAPE group are 4 times more common. The cause of delayed of the healing time of partial-thickness burns are the degree of bacterial contamination of wounds over 105 CFU / ml, and the presence of nosocomial micro flora (ESKAPE group). When used in the treatment of coverage based on hyaluronic acid, impaired wound healing was found four times less often than with the use of AP, UPM with high growth (CFU> 105) and resistant ESCAPEs were found 1,5 times less often than when used AP.
