Reliability of the Estimation of the Take of Split Thickness Graft by the Observation Method

In a study conducted from May 2016 to January 2017 involving 72 patients requiring split-thickness skin grafting, it was found that the traditional method of estimating skin graft success (termed as 'take') by observation is generally reliable. The study compared this observational method with the Image J method, a scientific image analysis program, and found no significant difference between the two, except for cellulitic wounds on Day 5 and flap site wounds on Day 14. However, the reliability of the observational method was dependent on the experience of the individuals making the estimation. Factors such as haematoma, shearing movements, inadequate compliance, deficient blood supply, and infection can adversely influence skin graft take. The study concluded that while an objective method like an image analyzer is ideal for estimating graft take, the observational method is also acceptable.
