Deeper Dive into Key Areas of IV Therapy and Peripheral Access

To further enhance your understanding of IV therapy and peripheral access, let's delve deeper into some key areas:

1. Vein Selection

Choosing the right vein for IV access is crucial for patient comfort and successful infusion. Consider the following factors when selecting a vein:

• Location: Start with veins in the non-dominant arm, if possible, and work distally to proximally. This approach preserves more proximal sites for future use.
• Size: Choose a vein that is large enough to accommodate the catheter without causing damage to the vessel wall. Avoid veins that are too small or fragile.
• Condition: Select a vein that is straight, smooth, and free of valves or bifurcations. Avoid veins that are sclerosed, thrombosed, or inflamed.
• Patient Factors: Consider the patient's age, medical history, and skin condition. Avoid veins in areas of injury, infection, or edema.

Common sites for peripheral IV access include the cephalic, basilic, and median cubital veins in the arm, as well as the dorsal metacarpal veins in the hand.

2. Catheter Selection

The choice of catheter depends on several factors, including the patient's age, the type of fluid or medication to be administered, and the duration of therapy. Here are some general guidelines:

• Gauge: The gauge of the catheter refers to its diameter. Smaller gauges (e.g., 22-24 gauge) are suitable for slow infusions and small veins, while larger gauges (e.g., 16-18 gauge) are preferred for rapid infusions and viscous solutions.
• Length: The length of the catheter should be appropriate for the size and depth of the vein. Shorter catheters are generally used for superficial veins, while longer catheters are necessary for deeper veins.
• Material: Catheters are typically made of polyurethane or Teflon. Polyurethane catheters are more flexible and less likely to cause phlebitis, while Teflon catheters are more durable and resistant to kinking.
