Perfusate Requirements for OCS Lung
Three units of leukocyte-reduced pRBC are transported and used as EVLP
perfusate (Figure 1). These pRBC units are Cytomegalovirus (CMV)
seronegative when indicated (both recipient and donor CMV seronegative).
With adequate time for recipient type & screen and ABO verification,
the primary preference is to utilize pRBC units released by the blood
bank at our institution. These units are ABO compatible with the donor
and cross-match compatible with the recipient. If cross-matched blood is
unavailable before the departure of the recovery team, our secondary
preference is to ask the donor site to provide pRBC units. In that case,
the organ procurement organization coordinator can provide leukoreduced,
pRBC units typed and screened against the donor in the donor operating
room (OR). If this second option is unavailable, our tertiary preference
is to utilize three of our institution’s pRBC units: emergency-release
leukoreduced group O+.
