Study Notes
Intravenous Drip
- The purpose of an intravenous drip is to administer fluids and medications directly into a vein.
Fluids Used in Intravenous Drip
- Commonly used crystalloid fluids include isotonic solutions like normal saline (0.9% sodium chloride) and lactated Ringer's solution.
- Crystalloids are solutions that contain dissolved crystalline substances, like salts and sugars.
- Crystalloids are often used for large volume fluid replacement in intravenous drips.
Intravenous Cannulation
- A tourniquet is used in peripheral intravenous cannulation to occlude the vein and make it more prominent for cannulation.
- A tourniquet should be released during peripheral intravenous cannulation after the cannula is advanced into the vein.
- A flexible intravenous cannula that contains a trocar at one end is called a scalp vein set.
- After observing flashback of blood in the cannula during peripheral intravenous cannulation, the cannula should be advanced further into the vein.
Securing the Cannula and Infusion Set
- After withdrawing the needle slightly during peripheral intravenous cannulation, the cannula should be advanced further into the vein.
- After securing the catheter with tape during peripheral intravenous cannulation, the tourniquet should be released.
Infusion Set
- The rubber tube in the infusion set connects the IV bag to the cannula and allows for the flow of fluids.
- The filter in the infusion set is responsible for filtering the solution to remove any particles or contaminants.
Medication Preparation and Administration
- In the medication preparation area, the IV solution should be prepared according to the prescribed medication order.
- At the patient's bedside during intravenous cannulation, the cannula should be inserted into the vein and secured in place.
Comparison of Crystalloids and Colloids
- The main difference between crystalloids and colloids in intravenous solutions is the molecular weight of the dissolved substances.
- A solution of 5% dextrose in water (D5W) would be used in intravenous drips to provide hydration and electrolyte-free fluid replacement.
This quiz covers the definition and use of peripheral intravenous cannulation, including the purpose of a cannula and the administration of intravenous drips for fluid infusion, medication delivery, or blood transfusion.
