Posted August 14, 20231 yr comment_86348 Is everyone else having a difficult time finding suppliers that still collect CPDA-1 units? Or, is it just us here in Southeastern US? Edited August 14, 20231 yr by Bet'naSBB
August 15, 20231 yr comment_86354 Our Red Cross just informed us that it will discontinue providing CPDA-1 rbc. We primarily used it to provide volume reduced red cells to pediatric patients under 3 years of age. We will volume reduce AS-1 or AS-3 by centrifugation or washing (Terumo 2991) instead. Probably unnecessary for most patients, but this is a long standing practice here, and it doesn't seem worthwhile trying to adjust pediatric practice in this regard. Most patients do not need the additional volume provided by the anticoagulant-preservative in AS-1, etc., and avoiding unnecessary volume is a reasonable goal in many patients. There is no inherent virtue to CPDA-1 vs. AS-1 and similar solutions, and rbc preservation is slightly better in AS-1/AS-3 by in vitro metrics. There is absolutely no factual basis for using CPD-A1 in preference to AS-1, etc. in pediatrics. Purely expert opinion and probably unduly conservative. I've attached a nice presentation by Dr. Saifee at the University of Washington, who createdAdditive solution AS-1 in Children Univ. Washington presentation Dec 2021.pptx it to educate her colleagues about using AS-1 instead of CPDA-1. Additive solution AS-1 in Children Univ.
