Detailed explanation-1: -The most common approach to preventing FNHTR and allergic reactions is to give the patient premedication with an antipyretic such as paracetamol and an anti-histamine such as diphenydramine.
Detailed explanation-2: -Quality control of blood supply and transfusion includes collection, documentation, storage, serological testing, administration and follow-up. The provision of serologically compatible blood requires meticulous monitoring of grouping, screening and crossmatching techniques.
Detailed explanation-3: -Non-immunologic reactions are usually caused by the physical effects of blood components or the transmission of disease. Bacterial contamination, for example, results in septic transfusion reactions and is caused by bacterial and/or endotoxin contamination of a blood product.
Detailed explanation-4: -Help prevent transfusion reaction by: Transfusing blood within 4 hours, and changing blood tubing every 4 hours to minimize the risk of bacterial growth at warm room temperatures.
