Lung transplantation. Hypothermic storage for 24 hours in a colloid hyperosmolar solution. 1978

L H Toledo-Pereyra, and R M Condie

We studied the effects of a colloid hypersomolar solution in perservation of lungs for transplantation in dogs. Fresh allografts were compared to lungs stored (4 to 7 degrees C), in Ringer's lactate for 3 hours and in modified silica gel function (MSGF) for 8, 16, and 24 hours before transplantation. Lungs preserved in Ringer's lactate for 3 hours were significantly damaged, and there were no long-term survivors in recipient dogs (1.2 +/- 0.4) (mean +/- S.E.). In contrast, the recipients of lungs preserved in MSGF for periods of up to 24 hours stored MSGF grafts = 10.5 +/- 3.1 days, survival, mean +/- S.E. Fresh Ringer's lactate grafts = 8.5 +/- 2.3 days, mean +/- S.E.; Fresh MSGF grafts = 13.6 +/- 3.8 days, mean +/- S.E.). Arterial blood gas measurements and chest roentgenograms were good methods of assessting the condition of preserved lung allografts. No significant differences were observed between the fresh and MSGF-preserved grafts. Pneumonia and rejection were the most frequent causes of death for both the fresh and MSGF-preserved allograft recipients. We demonstrate that a calloid hyperosmolar solution (MGSF) is a good method for 24 hours hypothermic storage of lung allografts for transplantation.

D009994	Osmolar Concentration	The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent.

D003102	Colloids	Two-phase systems in which one is uniformly dispersed in another as particles small enough so they cannot be filtered or will not settle out. The dispersing or continuous phase or medium envelops the particles of the discontinuous phase. All three states of matter can form colloids among each other.	Hydrocolloids,Colloid,Hydrocolloid
