| Background | The advent of Dried Plasma | Evolution | The Larger Plasma package | | Serum Albumin | Background:The use of blood transfusion as a treatment for shock was first introduced by the British Third Army troops during World War I. Members of the casualty Clearing Stations realized that hemorrhage was the single most important factor in causing casualty shock, and so plans and measures were made which allowed the most crude of Aid Posts to administer whole blood transfusions to casualties. Major W. Richard Ohler, who had served as a resuscitation officer during WW1 claimed that the amount of hemorrhage suffered determined the amount of shock suffered by a patient, and as a result the need for oxygen-carrying corpuscles, and no other form of saline solution, as had previously been thought. Despite the efforts of the British Third Army during WW1 and the claims by men such as Maj. Ohler, it was not until March 1918 that the US Army Medical Department officially adopted transfusion with citrated blood as the method for combating shock and hemorrhage in hospitals of the American Expeditionary Force. By 1939, both the Allies and Axis forces had seen the benefits of whole blood transfusion during the Spanish Civil War, in which over 9,000 liters of whole blood were collected and administered to casualties with the most severe symptoms of shock. A critical breakthrough was also made during the war, in that it was discovered that initial treatment of shock should include both whole blood and blood plasma, as opposed to earlier thought whole blood and serum. The “Blood for Britain” program, introduced during the 1940 had enjoyed limited success with whole blood, and in August of 1940, the American Red Cross began to collect blood from donors in New York City for export of plasma to Britain.
U.S. Army surgeons in the E.T.O. learned from British experience in the Western Desert, and from early American operations in North Africa and Sicily, that whole blood, while highly perishable and difficult to store and transport, was indispensable for controlling shock in severely wounded soldiers. Blood, administered as far forward as possible in the front lines and in the evacuation chain, saved many lives that plasma alone could not! The American “Blood Bank” program took shape during late 1943 and early 1944, and since no blood bank existed, everything had to be improvised!
Late in May 1944 (eve of D-Day), the Theater Blood Bank began collecting and processing, and its detachments started their first deliveries, i.e. over 1,100 pints to LSTs and British Hospital Carriers, fitting out at English, Scottish, and Welsh ports taking on blood and biologicals for their own use and for supply to the Beachheads the day of the Invasion … | Top |
The supply of whole blood plasma, either as frozen or liquid plasma proved to have limited success, but the need for the correct storage conditions meant that its use in the front line often meant access to refrigeration units, which in many cases were not available. As a result, large biological and pharmaceutical laboratories began to process whole blood into dried plasma. This new technology meant that plasma could be transported and stored by front line medical functions, and administered as and when needed. | Top |
The first 15,000 units of dried plasma were produced by Sharp & Dohme. These units consisted of two glass vials, one containing distilled water and the other, dried plasma. In addition an intravenous needle and rubber tubing were also supplied in the loosely packaged carton. While this equipment did represent the best method of frontline administration and reconstitution, the shape of the vials meant that an impractically large package was needed to supply the equipment to medical personnel in the front line. These original packages could yield a total of 220 cc. of plasma, although this was often less stable because a process of double-processing was required. In addition to their glass vials, both the distilled water and dried (desiccated) plasma were supplied in tin cans, although the packaging was so loose that breakage was considered inevitable. Despite these shortcomings, 25,000 units were ordered, but unsurprisingly, they did not stand up to use. In a meeting held on 19th April, 1941, Dr. Strumia developed a new form of package which was suitable for both dried and frozen plasma, and consisted of the following:
Unlike the earlier glass vials, the bottles in this new package would be placed in tin cans filled with nitrogen, and then sealed under vacuum. It was anticipated by Strumia that with slight modification the package would be acceptable for front line Army use.
At the 18th July, 1941 meeting of the Subcommittee on Blood Substitutes, the equipment and packaging developed by Commander Newhouser and Captain Kendrick, which were slight modifications of the Strumia packaging, were recommended for Army use and with only minor modifications, the packaging was used by the Army throughout the war.
The resultant Standard Army-Navy Package (Item # 1608900) consisted of the following:
Once the distilled water had been mixed with the desiccated plasma, within 3 minutes the plasma was ready for administration and was healthy for use for a further 4/5 hours. | Top |
Testing the Package:

As early as 1941, it had been realized that if a casualty needed plasma, 250 cc. (as supplied by the current Army-Navy Package) was insufficient. As a result the Army began developing larger packages which would yield more plasma, but maintain the practicability of the package. Experimental work had shown that by the use of a 750-cc. bottle, 600 cc. of plasma could be dried to a residual moisture of less than 1 percent. By the use of a 9½-inch can instead of the 7-inch can presently in use, 500 cc. of plasma could be packaged in a box only 2 inches longer than the box presently in use. Eighteen large packages would occupy the same space as 24 small packages but would represent the same quantity of plasma as 36 small packages. Production of this larger package did not begin until July of 1943, and the delay had been caused because it was feared that the change in tooling and dies necessary to produce the larger package would be a difficult process. In spite of this, the changeover was finally made and the larger packages began to find their way overseas. Production of the smaller, 250 cc. package was continued by Parke, Davis & Co., and Ben Venue Laboratories until the end of the war. | Top |
The Development of Serum Albumin:
Towards the end of the war, dried plasma began to be replaced by Serum Albumin, the most abundant plasma protein in human blood. The serum was preferable as it was a standard US Navy item used for the priming of explosives, and thus no delay was necessary in its procurement, unlike the dried human plasma. The development and introduction of this new item meant that another package had to be designed. Once again Commander Newhouser and Colonel Kendrick came up with a solution, as described below:
The versatility and compact nature of the serum package meant that by the Korean War (1950), it had totally replaced dried plasma as the main treatment for shock by front line troops. | Top |
The development of the Blood program in World War 2 was a real landmark, and the increased use of Whole Blood as well as Plasma was fundamental to medical success in saving the lives of wounded men! By the end of the Second World War, the American Red Cross had collected and processed over 6,000,000 standard Army-Navy Plasma Packages. While many of these packages were used during the latter part of the war, especially during “Operation Overlord”, surplus packages were shipped back to the Zone of Interior for use in Army Hospitals and for use by civilians. | Top |
