Intravenous (IV) therapy is a medical procedure that involves administering fluids, medications, and nutrients directly into a patient's vein. IV therapy is commonly used in hospitals, especially for paediatric patients, to provide quick access to essential fluids and medications. The process involves inserting a thin, flexible tube, known as a cannula, into a vein, typically in the hand, arm, or foot. This tube is connected to a syringe or external tubing, allowing for the delivery of the required substances. IV therapy is often chosen when oral administration is not feasible or when rapid distribution of medications and fluids throughout the body is necessary. While IV therapy is generally safe, it requires careful placement and monitoring to prevent complications such as infiltration or extravasation.

| Definition | Intravenous therapy (IV) is a medical process that administers fluids, medications, and nutrients directly into a person's vein. |
| Use Cases | IV therapy is used when oral medication is not viable due to nausea, vomiting, or severe diarrhea. It is also used for rehydration, providing nutrients to those who cannot or will not consume food or water by mouth, and administering medications or other medical therapies such as blood products or electrolytes. |
| Administration | A peripheral cannula is the most common intravenous access method. It is usually placed in the arm, specifically the wrist, hand, or median cubital vein at the elbow. A tourniquet may be used to restrict venous drainage and make the vein bulge for easier access. The cannula is then connected to a syringe or an intravenous infusion line. |
| Procedure | A needle pierces the skin and enters a vein, connected to a syringe or external tubing. This tubing is then connected to a bag of fluid or medicine. An infusion pump controls the flow rate and the amount of fluid entering the vein. |
| Risks | Infiltration, or leakage of fluid and medicine into the surrounding area, can cause swelling and discomfort. If the solution is colder than body temperature, it can induce hypothermia. Imbalanced concentrations can cause electrolyte imbalances. |
| Patient Experience | Topical numbing medicine may be applied to the area before placing the IV to reduce pain and anxiety. Parents are usually allowed to stay during the procedure. |

What You'll Learn
IV therapy is used to administer fluids, medication, nutrients, and blood
IV therapy is a medical procedure that involves administering fluids, medication, nutrients, and blood directly into a patient's vein. This method of treatment is often used in hospitals, outpatient care, and pre-hospital settings.
The process typically involves inserting a peripheral cannula, a thin, flexible tube, into a vein in the hand, arm, or foot. This cannula is connected to a syringe or external tubing, allowing for the delivery of the desired therapy. In some cases, a tourniquet may be used to restrict venous drainage and make it easier to locate and access the vein.
IV therapy is particularly useful when oral medication is not a viable option, such as when a patient is experiencing nausea, vomiting, or severe diarrhoea, which can interfere with the absorption of oral medication. It is also the preferred method when rapid administration of medication or fluids is required, as it directly introduces substances into the circulatory system, resulting in quicker distribution throughout the body.
The use of IV therapy ensures that patients receive the necessary fluids, medication, or nutrients directly into their bloodstream. This method is especially beneficial for paediatric patients who may struggle with swallowing medication or require quicker administration of fluids and medicines.
Additionally, IV therapy can be used to administer blood products and correct electrolyte imbalances. It is a versatile treatment option that has been recorded as early as the 1400s, with the practice becoming more widespread in the 1900s due to the development of safer and more effective techniques.

IVs are usually placed in the arm or hand
An IV, or intravenous line, is a soft, flexible tube placed inside a vein, usually in the hand or arm. This is done to administer medicine or fluids directly into the bloodstream.
The IV is placed in the arm or hand as these areas provide easy access to veins. The median cubital vein at the elbow, the wrist, or the back of the hand are common sites for IV placement. These areas provide visible and accessible veins that can accommodate the small tube, or cannula, that delivers fluids or medication.
The process of inserting an IV typically involves cleaning the chosen site, applying topical numbing medication, and using a tourniquet to restrict venous drainage and make the vein bulge. A needle is then inserted into the vein, with the attached IV tube following, before the needle is removed, leaving the tube in place. The tube is then secured with tape, a dressing, or a plastic cover.
The IV site is regularly monitored by nurses to ensure the IV remains in the correct position and to check for any signs of infiltration, which can cause swelling and discomfort. IVs are typically used when oral administration is not feasible or when rapid delivery of fluids or medication is required.
IV placement in the arm or hand is a standard and effective method for administering intravenous therapy, providing quick access to the circulatory system and allowing for efficient distribution of fluids or medication throughout the body.

IVs are small, soft, flexible tubes
An IV, or intravenous line, is a small, soft, flexible tube that is inserted into a vein, usually in the hand, arm, or foot. It is used to administer fluids, medications, and nutrients directly into a person's bloodstream. The use of IVs is particularly common in paediatrics, as children often have difficulty swallowing medication or may be unable to consume fluids orally.
The IV tube is thin and made of plastic, and it is connected to a syringe or external tubing, which allows the desired therapy to be administered. The IV tube is inserted into the vein using a needle, which is then removed, leaving only the soft tube in place. This tube is then taped to the patient's skin to hold it securely, and a plastic cover may be placed over the IV for protection.
The IV tube is connected to a longer, wider tube called a "giving set," which has a plastic spike at the end that connects to an IV bag containing the fluid or medication. This bag is hung on a pole that can be wheeled around, allowing for easy administration of fluids or medication. The IV bag may also be connected to an infusion pump, which controls the flow rate of the fluid and ensures the correct amount is delivered to the patient.
IVs are a safe and effective way to deliver therapy directly into the circulatory system, resulting in quick distribution throughout the body. However, it is important to ensure proper placement and monitoring of IVs to prevent complications such as infiltration, where the IV fluid enters the skin tissue instead of the vein.

IVs can be used to treat severe dehydration
IV, or intravenous therapy, is a medical process that involves administering fluids, medications, and nutrients directly into a person's vein. IVs can be used to treat severe dehydration, which is a contributing factor to many ailments.
IV fluids are specially formulated liquids injected into a vein to prevent or treat dehydration. They are used in people of all ages, from babies to the elderly, who are sick, injured, dehydrated from exercise or heat, or undergoing surgery. Intravenous rehydration is a simple, safe, and common procedure with a low risk of complications. It is particularly useful for those who are severely dehydrated and may be unable to consume fluids orally due to nausea, vomiting, or severe diarrhea.
IV therapy provides rapid rehydration, which can help alleviate symptoms of dehydration such as extreme thirst, lack of urination or dark urine, dry mouth, lips, and eyes, fatigue, and lightheadedness. It is also beneficial when the digestive system isn't working well, allowing for the intake of more fluids than one could consume orally.
IV rehydration therapy can be customized with additional vitamins and medications to address specific needs. For example, anti-nausea medication can be added to the IV if the person is experiencing vomiting, or vitamin B12 can be included for an energy boost.
It is important to note that IV therapy for dehydration should be medically advised and administered by a skilled professional. While it is a generally safe procedure, there are potential risks, including vein collapse, fluid overload, hematoma, infection, and infiltration.

IV therapy is the fastest way to deliver medications
Intravenous (IV) therapy is a medical procedure that delivers fluids, medications, and nutrients directly into a person's bloodstream via a vein. It is a quick and effective method for administering treatments, with the first recorded attempt dating back to 1492 when Pope Innocent VIII received blood from healthy individuals.
The procedure typically involves inserting a soft, flexible tube, known as a cannula, into a vein in the hand, arm, or foot. This tube is connected to a syringe or external tubing, which delivers the desired therapy. In some cases, a tourniquet may be used to restrict venous drainage, making it easier to locate and place the line in the vein. The part of the catheter that remains outside the skin can be connected to an intravenous infusion line or capped with a heplock or saline lock to prevent clotting between uses.
IV therapy is commonly used in hospitals, especially for paediatric patients, as it allows for easy administration of medicine and fluids. It is also employed when a patient is likely to receive multiple interventions in a short period, reducing the risk of trauma to the vein. However, it is important to note that IV therapy can have adverse effects, such as infiltration, which occurs when the cannula exits the vein, causing fluid to enter the skin tissue instead. Therefore, it should only be performed by skilled professionals who can monitor for any signs of complications.

Frequently asked questions
IV stands for Intravenous. It is a medical process that involves inserting a small tube called a catheter into a patient's vein. This tube is used to administer fluids, medications, and nutrients directly into the bloodstream.
An IV is the fastest way to deliver medications and fluids throughout the body as they are directly introduced into the circulatory system. It is also used when a patient is unable to consume food or water by mouth.
First, a tourniquet is tied to restrict venous drainage and make the vein bulge. Then, the area is cleaned and numbing medicine may be applied. Next, a needle connected to the IV tube is inserted into the vein and removed, leaving the tube in place. The tube is then taped to secure it and connected to a bag of fluid or medicine.
One of the most common adverse effects is infiltration, which occurs when the IV fluid goes into the skin tissue instead of the vein. This can cause puffiness, redness, and pain. If the fluid administered is colder than body temperature, it can induce hypothermia.
