Split-thickness skin grafting is widely used in the management of leg ulcers but is fraught with suboptimal take especially in less than ideal wound beds. The use of negative pressure dressing to prepare wound beds is an established practice. However, its use to improve graft survival is yet to be a common practice. We aim to compare quantitative and qualitative split thickness skin graft take in leg and foot ulcers using either traditional wound dressing or negative pressure dressing methods. Sixty-two cases were recruited for the study and assigned into two groups of 31 cases each by convenient sampling method. Group A patients had negative pressure dressings in both phases, whereas group B patients had traditional wound dressing in both phases. The percentage skin graft take for both groups, and the pattern of complications were assessed. Results were analyzed using IBM SPSS statistics for windows (version 21.0; IBM Corp, Armonk, NY). Student t-test was used to compare the percentage graft take, whereas Chi-square was used to compare significance of complications in both dressing methods. The negative pressure dressing showed better skin graft take with mean value of 99.2 ± 0.95% compared with traditional dressing with mean take of 89.7 ± 6.44%, which was statistically significant with a P value of <0.001. The complication rate was 12.9% in the negative pressure dressing group and 96.8% in the traditional wound dressing group, showing about 7.5 times more complication in the traditional wound dressing. This is statistically significant with a P value < 0.001. Negative pressure dressing for split-thickness skin graft contributes significantly to improved split-thickness skin graft take with reduced complication rate as compared with conventional wound dressing method.
