The first IV infusions
The concept of intravenous (IV) therapy is relatively new, but the idea behind this treatment is centuries old. The first documented attempt at IV therapy was performed in 1492 in Rome. A doctor tried to treat Pope Innocent VIII, who had fallen into a coma, by infusing him with the blood of three young boys. Unfortunately, the treatment was unsuccessful and the practice was abandoned for the next two centuries.
In the 1660s, an English experimentalist attempted the first blood transfusion between two dogs, which was also unsuccessful. However, this marked the beginning of a series of experiments with IV infusions. Sir Christopher Wren, an English architect, created the first successful IV infusion device in the late 1660s. Wren's device was made from a pig's bladder and a quill, and he used it to infuse a liquid mixture of wine, ale, opium, and liver of antimony into a dog's veins.
Over the next 200 years, doctors continued to experiment with animal-to-human transfusions and human-to-human transfusions, as well as improving the durability of IV devices. In the 1930s, Dr. Thomas Latta discovered that injecting saltwater into the bloodstream could help fight cholera, and Dr. James Blundell used transfusions to treat postpartum hemorrhages, finding that the speed of infusion impacted its success.
In the 1940s, nurses were allowed to administer infusions for the first time, speeding up treatment for those injured during World War II. Plastic tubes were also invented during this decade, and by the 1950s, intravenous therapy became a widely used practice in hospitals.

The development of IV therapy
The first documented attempt at IV therapy was recorded in 1492 when a doctor in Rome tried to treat Pope Innocent VIII by infusing him with the blood of three young men. Unfortunately, neither the Pope nor the donors survived, and IV therapy was not attempted again for the next 200 years.
In the 1660s, an English experimentalist, Sir Christopher Wren, created the first successful IV infusion device using a pig's bladder and a quill. With this device, he was able to infuse a mixture of wine, ale, opium, and liver of antimony into a dog's veins. Wren's colleague, Richard Lower, further refined the instruments and performed the first successful transfusion between animals in 1665. Despite these advancements, early attempts at IV therapy in humans were largely unsuccessful due to the limited scientific knowledge of the time.
In the 1930s, IV solutions became commercially available, and plastic tubes were introduced in the 1940s, improving the safety and comfort of IV therapy. During World War II, nurses were allowed to administer infusions, expediting treatment for the injured. By the 1950s, intravenous therapy became widely practised in hospitals, and Dr David Massa developed the first modern disposable IV catheter, known as the "Rochester plastic needle."
The 1960s saw the widespread use of IV treatment devices in American hospitals, with the introduction of IV infusion pumps and the plastic infusion bag. This decade also witnessed the work of Dr John Myers, who pioneered the use of IV therapy to deliver a "cocktail" of vitamins and minerals to patients. These advancements in transfusion and resuscitative therapies were accompanied by improvements in drug infusion technologies, demonstrating the dynamic evolution of IV therapy to enhance patient care. Advancements in IV therapy continue to be made to improve patient outcomes.

World War II and IV treatment
The use of intravenous (IV) therapy as we know it today is a recent development in the history of medicine. The practice of injecting fluids into a vein dates back to the 1600s, but it was not until the 1900s, after the development of techniques for safe and effective use, that IV therapy became widespread.
The devastation of World War II played a significant role in shaping the development and use of IV treatment. The urgency of treating those injured during the war led to a shift in how healthcare professionals utilised IV therapy. In the 1940s, nurses were allowed to administer infusions for the first time, a task previously reserved for doctors, to enhance the speed of treatment for wounded soldiers.
During this period, doctors began experimenting with plastic tubes for fluid delivery. The first plastic IV catheter was demonstrated in 1930, and in the 1940s, plastic tubes were invented, revolutionising IV therapy. These innovations paved the way for safer and more comfortable treatments.
By the 1950s, intravenous therapy had become a widely adopted practice in hospitals. Dr David Massa of the Mayo Clinic in Rochester, Minnesota, developed the "Rochester plastic needle" in 1950. This invention, consisting of a polyvinyl chloride (PVC) tube over a needle, marked a significant milestone as the first modern disposable IV catheter device.
The impact of World War II on IV treatment extended beyond the war years. The challenges of treating war injuries highlighted the importance of efficient fluid administration and prompted the development of more advanced IV devices. In the 1960s, IV infusion pumps became commonplace in hospitals, and the plastic infusion bag was introduced, further enhancing the accessibility and effectiveness of IV therapy.
Today, IV therapy is one of the most widely used treatments in medicine, playing a crucial role in rehydration, nutrient administration, and the delivery of medications and blood products. The evolution of IV treatment from its early beginnings in the 1600s to its widespread application during and after World War II has had a lasting impact on healthcare, saving countless lives and improving patient outcomes.
