SPS-1 (UW solution) is a clear to light yellow,sterile,non-pyrogenic solution for hypothermic flushing , storage and transportation of isolated abdominal organs.
The solution has an osmolality of 310 +or_ 15 mOsm/kg. 29 mEq/l, 125 mEq/l concentration of sodium and potassium respectively and a pH of 7.4 at 20o c.
SPS-1 must be cooled to 2 – 60c prior to use. The solution is flushed into the isolated organ before/after removal of organ. The solution is left in the organ vasculature during the hypothermic storage and transportation. SPS-1 is to be used for cold storage of the organ but not acceptable for continuous machine perfusion.
It can be stored at ambient temperature and cooled to 2 – 6o c prior to use.
