New organ preservation solutions

Area of Science:

• Transplantation
• Organ Preservation
• Surgical Innovation

Background:

• The initial intracellular solution for kidney preservation in 1969 led to the development of the University of Wisconsin (UW) solution.
• The UW solution became the accepted standard for hypothermic organ preservation.
• Ongoing research aims to refine and improve upon existing preservation techniques.

Purpose of the Study:

• To review advancements in hypothermic organ preservation solutions beyond the initial UW solution.
• To explore modifications, organ-specific requirements, and novel additives for improved organ viability.
• To assess the efficacy of new preservation strategies, including microperfusion and polyethylene glycol.

Main Methods:

• Review of research on modifications and simplifications of the UW solution.
• Investigation into organ-specific preservation requirements.
• Evaluation of pharmacologic agents, microperfusion, and polyethylene glycol solutions.
• Assessment of terminal rinse solutions to mitigate reperfusion injury.

Main Results:

• Simplifying the UW solution by removing components can enhance preservation.
• Organ-specific solutions are likely more effective than a universal approach.
• Microperfusion and polyethylene glycol show promise, achieving near-perfect 24-hour heart preservation.
• Terminal rinse solutions demonstrate potential for reducing reperfusion injury, pending clinical trials.

Conclusions:

• Hypothermic organ preservation has evolved, with potential for improvement over the standard UW solution.
• Organ-specific preservation strategies and novel additives offer promising avenues for enhanced outcomes.
• Further clinical evaluation is needed for promising techniques like terminal rinsing.
