phlebotomy

• The needle is inserted into the vein at a 15-30 degree angle, just below the bend of the elbow.
• The patient's arm is placed on an arm board or table, with the palm facing up.
• The needle is inserted into the vein at a 15-30 degree angle.
• A tourniquet is used to apply pressure to the vein and make it easier to locate and access.
• A tourniquet is applied to the upper arm above the elbow joint.
• A tourniquet may be used to increase blood flow to the area being punctured.
• A tourniquet is applied to the upper arm above the site where the blood will be drawn.
• Apply an adhesive bandage to cover the site and prevent infection.
• The tourniquet is tightened until the veins become engorged but not so tightly that it causes discomfort.
• The needle is inserted into the vein at a 20-degree angle.
• If necessary, apply pressure with gauze or cotton balls over the site until bleeding stops.
• After inserting the needle, wait for blood flow to begin before collecting any specimens.
• The tourniquet is inflated until the veins become visible but not so tight as to cause discomfort.
• If there are no visible veins, use ultrasound guidance to locate them.
• The tourniquet is released once the needle has been inserted into the vein.
• If necessary, reapply the tourniquet briefly during the procedure to maintain venous distention.
• The tourniquet is released once the needle has been removed from the vein.
• Remove the needle from the syringe or tube, release the tourniquet, and gently massage the area to encourage blood flow back into the body.
• Remove the tourniquet immediately after drawing the sample, as prolonged use can cause damage to the tissue.
• An alcohol swab is used to cleanse the skin over the vein.
• Dispose of all materials properly according to hospital policy.
• After removing the needle from the patient's skin, gently remove the syringe or collection tube from the needle hub.
• Blood flows from the vein through the needle into the syringe or collection tube.
• Clean hands with soap and water or alcohol-based hand sanitizer.
• After the desired amount of blood has been collected, remove the needle from the vein.
• Remove the tourniquet immediately if there are signs of venous stasis syndrome (blanching).
• Instruct the patient on how to care for the site post-procedure.
• Insert the needle into the vein at a 15-30 degree angle.
• Venipuncture can cause pain, bruising, hematoma formation, nerve damage, arterial puncture, air embolism, and infection.
• A sterile alcohol swab is used to cleanse the skin around the puncture site.
• Potential complications include hemolysis, clotting, lipemia, icterus, and hyperlipidemia.
• Blood collection tubes are filled according to laboratory requirements.
• Wait for blood flow to start before starting collection.
• Apply gentle pressure on the puncture site if needed.
• Avoid applying too much pressure when removing the tourniquet, as this can cause pain and bruising.
• A sterile gauze pad or cotton ball is placed over the puncture site immediately following collection.
• A small amount of blood may be drawn back into the syringe during venipuncture.
• Blood collection tubes must be filled completely within one minute of drawing blood.
• Apply gentle pressure with the gauze/cotton ball for at least one minute to stop bleeding.
• When using an IV catheter, it's important to avoid puncturing the skin more than one time per session.
