Recently, various methods using scientific investigation have been used at crime scenes, and investigations have been conducted in various ways if a dead body is found at the scene.
Statistics on deaths in recent years show an increase in a lot of people with diabetes and high blood pressure as life expectancy increases. These diseases are associated with chronic renal failure, which in most cases leads to hemodialysis.
Even if kidney transplants are possible due to the matching physical environment with the kidney contributor, it must be dialysis two to three times a week before transplantation, which can be seen as a sign of this in all patients. In this study, we would like to systematize these particular cases and propose new ways to improve the identification of the dead body in the examination. Common scars are usually classified into five categories, as follows: It is classified as skin wrinkles and contorted scars, atrophy scars, skin suture scars and keloids. There are also scars caused by moxibustion or saliva. Blood dialysis patients have a unique scar that distinguishes them from these shaped scars, which are divided into those caused by the introduction of artificial blood vessels needed for dialysis and those caused by sympathetic veins.
In this paper, we found that scars caused by hemodialysis are completely distinguished from ordinary scars and scars caused by saliva or moxibustion, and can be distinguished by the duration of dialysis rather than by gender or age. In particular, there was a phenomenon of prominent scars over dialysis time. The database was collected to convey accurate information knowledge about blood dialysis to the coroners and to improve understanding.
In this study, we surveyed the scar and skin characteristics of hemodialysis patients in detail and organized the method of identifying them. We want to provide accurate information about blood dialysis to medical examiners who have not been trained in hemodialysis, improve understanding, analyze the cause of death of the deceased, and suggest a developmental direction for identifying the cause of death in the future.
