Analysis of Interactions Between Components of Selected Solution for Organ Perfusion and Preservation

BACKGROUND

In the literature there is a great deal of information about the activity of liquid preservatives and the solutions used to modify them; however, there is no information about the possibility of interactions between them during multiorgan retrieval. The aim of the study was to analyze the possibility of reactions between the components of Biolasol and histidine-tryptophan-ketoglutarate (HTK). Biolasol is the first Polish liquid preservative intended for rinsing kidneys, livers, and pancreases by simple hypothermia. HTK is a cardioplegic fluid used in organ preservation of hearts, livers, kidneys, pancreases, and lungs.

METHODS

Biolasol and HTK solution were used for the tests. The preservatives were mixed together at 1:1, 0.25:0.75, and 0.75:0.25 ratios. The volume of mixtures to be analyzed was 500 mL. The prepared systems were stored in a refrigerator (4°C) protecting against light. The systems were subjected to physicochemical analysis involving pH, density, viscosity, buffer capacity, osmolarity, and absorbance measurements as well as visual and microscopic assessment at time intervals: immediately after mixing (t = 0) and after 12, 24, 48, and 72 hours.

RESULTS

The analysis suggests that interactions between solution components can occur and have a positive effect on storage time and effectiveness of organ rinsing.

CONCLUSIONS

The use of Biolasol and HTK in multiorgan retrieval is safe.

Swine model in transplant research: Review of anaesthesia and perioperative management

Pigs are one of most common animal species to be used in biomedical models due to their many anatomical visceral similarities with humans, particularly with regards to transplantation. Despite this use, in many of the researches in which pigs are selected for transplantation, the anaesthesia used is an adaptation of human anaesthesia and presents some limitations such as a reduced analgesia a limited control in perioperative period. In this review we show some of the most important conditions in the preanaesthetic management and of swine as well as we review of anaesthetic protocols for the most common types of swine model of transplantation.
