Randomized Controlled Trial
A prospective randomized controlled trial comparing negative pressure dressing and conventional dressing methods on split-thickness skin grafts in burned patients.
Split-thickness skin grafting (SSG) is a technique used extensively in the care of burn patients and is fraught with suboptimal graft take when there is a less-than-ideal graft bed and/or grafting conditions. The technique of Negative Pressure Dressing (NPD), initially used for better wound healing has been tried on skin-grafts and has shown to increase the graft take rates. However, comparative studies between the conventional dressing and vacuum assisted closure on skin grafts in burn patients are unavailable. The present study was undertaken to find out if NPD improves graft take as compared to conventional dressing in burns patients. ⋯ Negative pressure dressing improves graft take in burns patients and can particularly be considered when wound bed and grafting conditions seem less-than-ideal. The negative pressure can also be effectively assembled using locally available materials thus significantly reducing the cost of treatment.

Comparative Study
Early depth assessment of local burns by videomicroscopy: 24 h after injury is a critical time point.
Videomicroscopy has simple and prompt operability, and useful in the burn depth assessment in its early phase. A burn wound is, however, a dynamic environment in the first few days and the critical time to assess a burn wound by videomicroscopy has not been investigated. The aim of this study is to investigate the critical time point to assess the burn depth by videomicroscopy. ⋯ Videomicroscopy is effective tool in assessment of early burn depth and the critical time point to assess the burn depth by videomicroscopy is 24 h after injury.

In light of changes in patient demographics together with constant developments in burn care, the predictive accuracy of the Abbreviated Burns Severity Index (ABSI) - first described in 1982 - for estimating the mortality of present day burns patients, may be questionable. We reviewed the records of 2813 burns patients treated between January 1968 and December 2008 in the intensive care unit at our institution, aiming to identify emerging discrepancies between the estimated and calculated outcome, based on each of the ABSI variables and the total burn score. ⋯ Nevertheless, the ABSI for the estimation of mortality in our entire patient collective was highly accurate and could not be optimised by adapting the point distribution to the increase in OR. Our data indicates that despite significant changes in patient demographics and medical advances over the past 30 years, the ABSI scoring system is still an accurate and valuable tool in the prediction of burn patient mortality.

Function of the skin lymphatics as well as blood perfusion of a meshed transplant is crucial for the healing. The lymphatic regeneration and arterial perfusion of skin transplants after severe burns of the extremities had been studied in eight patients by microlymphography, laser doppler perfusion imaging and transcutaneous oxygen pressure measurements 1, 6 and 18 months after transplantation. One month after transplantation, only fragmented as well as many giant lymphatic skin vessels were present in the transplant. ⋯ By contrast, transcutaneous oxygen measurement (TcPO(2)) increased from 44 (21-47) to 55 (50-76) mmHg. In meshed transplants used to cover severely burned skin morphological and functional normal lymphatics develop within 6 months and the initially increased laser flux due to inflammatory reaction normalises. Our results provide important insights into the healing process of skin transplants after burn.
