What is the recommended angle for inserting a peripheral IV catheter?

The recommended angle for inserting a peripheral IV catheter is between 15 to 30 degrees. This angle is optimal because it allows for easier access to the vein while reducing the risk of puncturing through the vessel or causing unnecessary trauma to the surrounding tissue. When the angle is too shallow (like 5 to 10 degrees), it may not provide enough penetration to enter the vein and could cause the catheter to slide out if not properly positioned. On the other hand, too steep of an angle (such as 30 to 45 degrees or higher) increases the risk of puncturing through the vein wall or missing the vein altogether, leading to infiltration or extravasation. Therefore, maintaining an insertion angle of 15 to 30 degrees strikes the right balance, aiding in successful catheter placement and minimizing complications.
