Role Of Blood Bag In The Revolution Of Hospital Management
The blood bag may seem like a quite basic piece of storage, but the development of this was a turnabout in our medical history.
Without the possibility of a blood transfusion there are numerous operations which could not be completed and would never have been attempted. We take the concept of a blood transfusion for granted. But actually, a blood transfusion is a somewhat recent improvement.
Initially there was no way to store blood, so a transfusion had to be directly from one vein into another vein. This was of course very limiting. Blood could not be preserved until an appropriate anticoagulant was found. Richard Lewison discovered this in 1915; sodium citrate.
Within just a couple of years blood was being donated and stored for a couple of days at a time. This gave many of those wounded during the last years of the First World War an opportunity to thrive.
The blood was being collected and stored in glass jars. It was already discovered that blood could be divided into its component parts of blood plasma and red blood cells; but this was very risky due to the chance of contamination during the process.
Nonetheless, with the growth by Fenwal Company of the plastic blood bag in 1953 it all changed. This was an easy way to store and transfer blood with minimal contamination risk; suddenly so much more was possible.
The first blood banks were set up in the Soviet Union, United States and Europe in the late 1930s. Although it would take many years to upgrade the glass storage jars, in all places, the process was started and immediately there were more and more uses of blood transfusions and more difficult surgeries were happening with this extra support.
So now the blood could be collected, divided, and stored; but transportation still needed to be conquered. Blood needs to be stored at the right temperature and a constant temperature. Just as the mobile phone has gone from the size and weight of brick to something not much bigger than a credit card; so the transport of blood has progressed.There are now thermal blood carrying bags which allow medics to take blood to where ever it is needed. These are essential for the quick and effective treatment we have all come to expect.
So the little blood bag has revolutionised our planet, and yet many people will never hear the names of the people who are responsible for saving lives every minuet of every day.
