DIAGNOSTIC OF PANCREATIC INJURY USING INFRARED THERMOMETRY.

Abstract

Aim: the study of the dynamics of changes in the temperature indicators of the injured pancreatic tissues in various types of mechanical trauma, depending on the time elapsed since the injury and the time of death.

Material and methods: The material of the study was the pancreatic tissue of 256 individuals, both male and female, aged 20 to 60, who died with a known time of injury and time of death, with or without the presence of alcohol in the blood.

Results: The article analyzes the issue of diagnostics, determining the time of injury and time of death. In the course of the conducted studies, statistically reliable dynamics of temperature decrease was revealed in both injured and intact pancreatic tissues in individuals who died from injuries, which can be used as one of the criteria for determining the time of injury. The study revealed that higher quantitative temperature indicators are observed directly in the area of pancreatic damage in comparison with uninjured pancreatic tissues with an average difference of 1.5-3ºC (±0.17). It was established that the sex of a person (male or female) does not significantly influence the temperature indicators of the pancreas.

Conclusions: Based on the results of the study, a regression model was proposed for using to determine the time of death. This model takes into account the temperature indicators of the parenchymal organs of the abdominal cavity and retroperitoneal space in combination (liver, pancreas, spleen, kidneys) in dynamics at both positive and negative temperatures, using a modern method of infrared thermometry.
