The IV cannulas of 14g, 16g, 18g, and 20g are available in various types. Each of these types caters to divergent medical utilization. The intraosseous cannulas consist of a needle with a plastic sheath, which is also known as a canula. Moreover, the most common types of IV cannulas include regular, butterfly, and fetal intrauterine blood transfusion cannulas.
The regular IV cannulas are used for intravenous fluid therapy and drug delivery. That is why they are the most commonly used. These are also available in various gauges. The intrauterine fetal blood transfusion canulas are destined to be used in pregnant patients for blood transfusion to the fetus. On the other hand, the butterfly IV cannula is a short-term use idea. It is commonly used for drawing blood.
Regular IV cannulas are made from various materials, including metals and plastics. Steel needles are the most common material used to make the needles themselves. Plastic materials are to manufacture the cannula body portion due to the need for sterility and disposability; other materials used in its construction include rubber and silicone. The butterfly IV cannula consists of a plastic body and metal wings. That makes butterflies easy to grip and provides stability when inserted. An intrauterine fetal blood transfusion IV cannula is made of flexible PVC plastic. Hence, it is durable and non-toxic. Intraosseous IV cannulas are most commonly made from titanium alloys. They also consist of biocompatible materials that are not toxic to the human body.
IV cannulas are primarily used in hospitals, clinics, and other healthcare settings for the administration of fluids, medications, and blood products. They are commonly employed in emergency situations, surgeries, and critical care settings to ensure timely and effective treatment.
Manufacturers and suppliers distribute IV cannulas to healthcare facilities, ensuring an adequate stock for medical procedures. They also collocate the cannulas with safety features like needle shields and valves to reduce the risk of needlestick injuries to healthcare workers.
IV cannulas of varying gauges are recommended for distinct medical procedures. While the larger gauges, like 14g and 16g, are suitable for high-volume fluid resuscitation, the smaller ones, such as 20g and 22g, are ideal for routine medication administration.
The monitoring of patients frequently involves the use of IV cannulas. In critical conditions, healthcare professionals can keep the cannula patent to continuously administer fluids and medications. The durability and flexibility of the intrauterine cannulas make it possible to perform invasive prenatal procedures like amniocentesis.
IV cannulas are indispensable in blood transfusions and organ transplants. In such uses, maintaining sterility and safety is paramount. In emergencies, intraosseous cannulas are vital when IV access is challenging. This makes it a lifesaving alternative to administer fluids and medications directly into the bone marrow.
In veterinary medicine, IV cannulas are used for fluid therapy and medication administration in animals. The cannulas used on animals share several similarities with those employed in human medicine. However, they are specifically designed to accommodate the anatomical differences of various animal species.
The IV cannula is made from non-toxic, medical-grade PVC to provide maximum flexibility and safety. These cannulas are impervious to gamma radiation, protecting them from sterility. PVC is a biocompatible material that ensures the IV cannula will not react with the body tissues or fluids. Thus, it is good for extended use. The IV cannula's sharp steel needle ensures precise and smooth insertion, minimizing discomfort for the IV fluid administration procedure. The needles are coated with a thin layer of silicone. It facilitates effortless insertion and enhances the patient's comfort. The steel needles are strong enough to pierce tissues without bending or breaking.
The IV canulas 14g, 16g, 18g, and 20g are manufactured in sterile environments. They are individually packaged and sterilized using ethylene oxide gas. EO sterilization is a standard method to ensure the sterilization of medical devices. It is effective against a large spectrum of microorganisms.IV ca1nulas should be stored in cool, dry, ventilated areas, free from direct sunlight or heat, at normal temperatures. They should remain sealed in their original packaging until ready for use.
The gauges of IV canulas range from 14 to 20, with increasing size in the number of gauges, thus increasing in thickness and flow rate. Larger gauge 14- and 16-g canulas are ideal for high-flow situations, including blood transfusions or thick fluid administrations, while 18g and 20g canulas are more suited for routine IV therapies, including medication administration and fluids. Extended period use can be realized through the use of gleaming urethan lining of lumens. This enhances patency and minimizes thrombus formation. Furthermore, the cannula has a retractable safety cap that protects against needlestick injuries after use.
A. The IV cannula is used to administer fluids, medications, and blood, provide oxygenation, and achieve electrophysiological recordings during cardiovascular procedures.
A. The most common types of IV cannulas are 14g, 16g, 18g, and 20g. They are used for general procedures, including hydration and blood transfusions.
A. The IV cannula is gauged by the inner diameter it offers. Hence, a 14-g canula has a larger diameter than a 20-g canula. Thus, a 14-g cannula will be better for rapid infusion.
A. An IV cannula is designed to last between 72 and 96 hours under ideal conditions. These conditions include good patient compliance and the absence of complications like infection.
A. Ideally, the IV cannula should be replaced every 72 to 96 hours. However, if the IV site is compromised before the due time, the IV cannula should be taken out and replaced.
