Peripheral intravenous catheters (PIVCs)
The history of PIVCs dates back to the Middle Ages, when there were fledgling attempts to exchange blood between people. However, the development of modern PIVCs can be traced back to the 19th century, with the work of pioneers like Philip Syng Physick, who first suggested human-to-human blood transfusions, and Dr. James Blundell, who successfully performed a series of human blood transfusions in the early 1800s.
In the late 19th century, cholera outbreaks in Europe further propelled the evolution of intravenous (IV) therapy. Dr. William Brooke O'Shaughnessy discovered that cholera victims lost large amounts of water and saline from their blood, and Dr. Thomas Latta successfully treated patients with intravenous saline using a syringe and silver tube.
The plastic revolution in the 1950s led to significant changes in medicine, including the development of polyvinyl chloride IV catheters. These plastic catheters became commonplace due to the frequency of IV failures, particularly infiltrations. By the 1960s, IV treatment devices were routinely used in most American hospitals.
Today, PIVCs continue to play a vital role in healthcare, offering a range of therapeutic and diagnostic interventions for both pediatric and adult patients. With advancements in technology, different PIVC configurations have emerged, each with specific characteristics and suitability for particular infusion therapies. Clinicians must carefully select the appropriate PIVC type to ensure optimal patient care and preserve patients' vessel health.

The history of transfusion therapy
The earliest attempts at transfusion therapy date back to the Middle Ages, when doctors attempted to exchange blood between people. The first historical documentation of transfusion therapy was in 1492, when a doctor attempted to treat Pope Innocent VIII in Rome.
In the 17th century, Lower created an apparatus for transfusion that included a tapered silver tube for placement in a blood vessel. This early form of transfusion therapy laid the foundation for the development of modern syringes and needles.
The next significant advancement in transfusion therapy came in the 20th century with the invention of plastic. Polyvinyl chloride was the first plastic used in medical equipment, followed by Teflon and polyurethane. This led to the development of plastic tubes and catheters that could be used for intravenous (IV) therapy.
In 1950, the invention of the Rochester needle by Massa revolutionized IV therapy. This led to the development of 'over-the-needle' catheters, which are now used to deliver almost all IV therapy worldwide. The addition of filters, pumps, electronic infusion devices, and safety features has further revolutionized transfusion therapy and medicine.
Today, peripheral intravenous catheters (PIVCs) play a vital role in infusion therapy, enabling a range of therapeutic and diagnostic interventions in both pediatric and adult care. The evolution of transfusion therapy, from early attempts to exchange blood to the sophisticated plastic devices of today, has transformed medical practice and improved patient care.

The development of polyvinyl chloride IV catheters
Polyvinyl chloride (PVC) is a plastic material widely used for medical products such as blood bags, tubing, examination gloves, and medical trays. The development of polyvinyl chloride IV catheters has played a vital role in revolutionizing infusion therapy, allowing for therapeutic and diagnostic interventions in both paediatric and adult care.
The history of IV therapy is intertwined with the history of blood transfusion attempts, with the first historical documentation of attempted IV therapy dating back to 1492, involving a doctor caring for Pope Innocent VIII in Rome. In the 20th century, medical equipment began to be made of plastics, with polyvinyl chloride being the first plastic used, followed by Teflon and polyurethane. The invention of the Rochester needle in 1950 by Massa led to the development of 'over-the-needle' catheters, which are now used to deliver most IV therapy worldwide.
The plastic revolution dramatically changed the medical field, and the development of polyvinyl chloride IV catheters significantly improved the administration of IV fluid therapy. Peripheral intravenous catheters (PIVCs) are small, flexible tubes placed into peripheral veins to administer intravenous therapy such as medication fluids. They are the most commonly used vascular access in medicine, especially in emergency departments and surgical patients. PIVCs have specific characteristics and suitability for different infusion therapies, and clinicians must carefully select the appropriate type for each patient to ensure vessel health.
While polyvinyl chloride is commonly used as a catheter material for clean intermittent catheterization (CIC), environmental and health concerns have led to the development of PVC-free alternatives. These alternatives, such as the LoFric catheter, are made of polyolefin-based elastomer (POBE) and have been proven safe and comfortable. However, they are continuously being improved to enhance patient comfort and reduce adverse events such as discomfort, pain, bleeding, and burning sensations.
