Tips for optimizing organ preservation solutions

Abstract

Organ injury during ischemia is one of the clinical problems of today's transplantation. It occurs during warm ischemia time (WIT) when the blood flow is cut off and during cold ischemia when a graft is chilled in situ until the circulation is restored to the recipient organism. Fast cooling of the organ slows metabolism and activates intracellular enzymes, which minimizes the effects of warm ischemia. Unfortunately, hypothermia also results in inhibition of ATP synthesis, cell swelling and intracellular acidity. That is why research is continually being conducted to develop new fluids for rinsing and storing organs as well as to optimize the composition of those that are already in use, which will allow for longer and more effective graft storage and restoration of its optimal functions after transplantation. The article provides current information on rinsing and storage fluids available on the global market. It also discusses the directions of fluid modification with hormones and micronutrients.
