Secondary damage in trauma may increase morbidity,mortality and the cost of treatment *** article reviews the literature of 46 relevant articles on this *** hope to provide a better understanding of the various mechanisms that can lead to secondary damage following major trauma and aim to improve the management of such in trauma *** also explore the utility of limited access dressing and its ability to minimize and treat secondary musculoskeletal *** interdependent cellular mechanisms have been described that contribute and perpetuate secondary tissue damage-lysosomal,protein/enzyme denaturation,membrane permeability and *** changes are mainly due to systemic hypoxia and the systemic inflammatory response *** access dressing appears to be an efficient and cost-effective method for the management of secondary damage,as evidenced by the reduced number of debridements,shorter wound coverage time,and reduction in total length of hospital stay while lowering treatment costs and improving quality of care.

Aim:Changes in the pH of chronic wounds can inhibit the optimal activity of various enzymes in the wound environment,thereby delaying wound *** aim of the present study is to monitor the effect of limited access dressing(LAD)on the pH on the surface of chronic ***:A total of 140 patients with chronic wounds of more than 4 weeks duration were divided into two groups by simple randomization:a LAD group(n=64)and a conventional dressing group(n=76).Fifty-six participants(22 in the LAD group and 34 in the conventional dressing group)were lost to follow-up or withdrawn from the ***:In the LAD group(n=42),the mean age was 38.3±10.56 years(range:12-60 years),and the mean wound size at the time of admission was 28 cm^(2)(range:19-40 cm^(2)).In the conventional dressing group(n=42),the mean age was 35.3±14.0 years(range:17-65 years),and the mean wound size at the time of admission was 26 cm^(2)(range:18-39 cm^(2)).Patients treated with LAD showed a significant decrease in the mean±standard deviation pH when compared with the conventional dressing group(0.83±0.52 vs.0.41±0.26,P=0.048).Conclusion:LAD reduces the chronic wound surface pH to a level required for the optimal function of various *** could be a factor that exerts a beneficial effect on wound healing.

Aim:Negative pressure wound therapy(NPWT)has achieved widespread success in the treatment of chronic ***,its effects have been only partially explored,and investigations have generally concentrated on the wound-dressing interface;a detailed histopathological description of the evolution of wounds under NPWT is still *** present study was performed to investigate the effect of a limited access dressing(LAD)which exerts intermittent NPWT in a moist environment on chronic ***:A total of 140 patients were randomized into 2 groups:LAD group(n=64)and conventional dressing group(n=76).By histopathological analysis of the granulation tissue,the amount of inflammatory infiltrate,necrotic tissue,angiogenesis,and extracellular matrix(ECM)deposition was studied and compared to determine healing between the 2 ***:After 10 days of treatment,histopathological analysis showed a significant decrease in necrotic tissue with LAD compared to the conventional dressing group(mean±standard error,11.5±0.48 vs.10.1±0.30,P=0.007),the number of inflammatory cells(12.6±0.60 vs.8.63±0.35,P=0.018),a significant increase in new blood vessels(12.8±0.58 vs.9.3±0.29,P=0.005)and ECM deposit(13.3±0.50 vs.9.6±0.24,P=0.001).Conclusion:LAD exerts its beneficial effects on chronic wound healing by decreasing the amount of necrotic tissue and inflammatory cells while increasing the amount of ECM deposition and angiogenesis.
