plural persufflations

1. medicineThe technique of gently streaming oxygenated air through the blood vessels of a chilled organ for the purpose of organ preservation.

   In a porcine model, gaseous oxygen persufflation prevented primary non-function of livers after extended cold-storage times and improved one week survival of the recipient from 0% to 83%.

   In venous oxygen persufflation, cold, humidified, oxygen-rich gas is supplied at hypothermic termeratures and low controled pressure via the venious system (e.g. in the kidney via the renal vein).

   Although there are some conflicting data, the majority of evidence suggests that persufflation, by enhancing oxygenation, can improve preservation and even rescue organs, including organs with prior warm ischema.
