In order to promote rational use of blood and its availability, Union health ministry is planning to monitor 1163 component separation facilities in the country on a monthly basis to ensure consistent availability of blood and blood components to the common man.

This comes as a welcome change as according to a senior health official, the concept of component separation need to be embraced in the current scenario as blood availability through voluntary donation is increasing. Therefore there is an urgent need to maximise the use of every unit of blood procured by blood banks. When separated, a unit of blood will meet the requirements of more than one patient. Many ailments call for the transfusion of only specific components, not whole blood. There are other advantages of separation, such as the extended shelf life of components.

There are over 2760 blood banks across the country. Nearly 80 per cent of the blood collected is transfused as whole blood. One practical way of using blood effectively is to separate its various constituents -red blood concentrates, fresh frozen plasma, cryoprecipitates and platelet concentrates, according to a health official.

In a dengue affected patient, platelet count in the body goes down, weakening immunity. Since there is no medication available to cure the disease, it becomes imperative to improve the platelets level.

Components are to be separated from blood within six hours. Plasma separated from blood can be further fractionated to produce many useful life-saving components such as Factor VIII, fibrinogen, albumin and gamma globulin.

There has been an increase in voluntary blood donation from 38 to 95 per cent between 1997 to 2014. Blood collection has increased from 3. 6 lac units in 1997 to 14.76 lac units in 2014 through a six fold increase in blood donation camps in Maharashtra alone.

Blood bank officials clarify that Maharashtra alone is equipped with 250 component separation facilities attached with the blood banks.

Experts however say that besides the fact that blood banks primarily stock whole blood based on voluntary blood donation drives, there is also a need to strengthen hospital blood banks to aggressively take up component separation to generate packed cells, platelets and plasma on a consistent basis. Simultaneously, there is a need to develop peripheral hospitals in the city on the lines of blood storage centres, experts say.
