How long can tourniquet be left on arm for blood draw?
A tourniquet should be left on the arm for no longer than 1-2 minutes for a blood draw. Leaving it on for longer can lead to complications like tissue damage, nerve injury, or blood pooling. It's important to release the tourniquet once the needle is inserted to prevent any adverse effects.
What happens when removing the needle before the tourniquet?
Removing the needle before the tourniquet can lead to several complications, including increased bleeding at the puncture site due to the pressure from the tourniquet being released. It may also cause discomfort or pain for the patient, as the pressure from the tourniquet can help stabilize the vein during needle withdrawal. Additionally, this practice can increase the risk of hematoma formation, as blood may leak into the surrounding tissue once the needle is removed. Proper protocol typically dictates that the tourniquet should be released before or simultaneously with needle withdrawal to minimize these risks.

A tourniquet is applied during phlebotomy to temporarily restrict blood flow in the veins, making them more prominent and easier to locate and puncture. This enhances visibility and access to the veins, facilitating the collection of a blood sample. It also helps to minimize the risk of hemolysis and ensures a more accurate sample by preventing blood dilution from surrounding tissues. The tourniquet should be removed as soon as the needle is inserted to reduce discomfort and potential complications.
