Decreasing Blood Wastage During Ex Vivo Lung Perfusion Recovery Through
Utilization of Thermal Control Technology
Abstract
Background The Organ Care System (OCS) is a revolutionary ex
vivo organ perfusion technology that can potentially expand the organ
retrieval range. The OCS Lung device uses packed red blood cells (pRBC)
with a proprietary solution. We report the ability to reduce blood waste
during this procedure by using a thermal packaging solution in
conjunction with the OCS platform. Methods We retrospectively
reviewed all OCS Lung recoveries performed by our recovery team, using
packed red blood cells (pRBC) from May 2019 to January 2021. Initially,
units were stored using passive refrigeration with the Performance
cooler at a temperature range of 1 to 6 °C for 4 hours. Subsequently,
thermal control technology with the ProMed cooler was utilized to
maintain the same temperature range for 72 hours. Results
Twenty-three recoveries were initiated with 63 pRBC. The Performance
cooler was used for eight while the ProMed cooler for thirteen. 37.5%
of pRBC transported with the Performance cooler was used within the
validated time range, while 25.0% were used beyond the validated time
range based on clinical judgment. In addition, 37.5% of pRBC
transported with the Performance cooler were returned to the institution
after canceled recoveries with an estimated loss of $1,800; the ProMed
cooler had no wastage. Conclusions This study showed that using
an advanced thermal packaging solution facilitates proper storage of
pRBC and represents an advancement for extended donor lung preservation.
The elimination of blood wastage in this initial study portends ongoing
benefits for the limited blood supply and reduced cost.
