1. The Antecubital Fossa:

The antecubital fossa, located on the inner side of the elbow, is one of the most common sites for IV cannulation. Its prominent veins, such as the median cubital vein, make it easily accessible. However, special care should be taken as this area is prone to venous scarring in patients who frequently receive IV therapy.

2. Dorsal Hand Veins:

If the antecubital fossa is inaccessible or unsuitable, the dorsal hand veins can be an excellent alternative. They are easily visible and palpable, making them suitable for obtaining blood samples and initiating IV therapy. However, caution must be exercised while puncturing these veins, as they are more prone to extravasation due to their small size.
