Bedside Washing of Stored Red Blood Cells: A Simple Apparatus Based on Microscale Sedimentation in Normal Gravity
… a short period without any alteration to current blood collection and storage practices. Washing pRBC units prior to transfusion is recommended for hypersensitive patients who have a higher susceptibility towards Allergic Transfusion Reactions (ATR) due to residual plasma proteins. Unfortunately, …
