Gloves are to be worn during all phlebotomies, and changed between patient collections. 7. Palpation of phlebotomy site may be performed without gloves providing the skin is not broken. 8. A lab coat or gown must be worn during blood collection procedures. 9. Needles and hubs are single use and are disposed of in an appropriate ‘sharps’ container as one unit. 10.

All surfaces are cleaned daily with bleach. 14. In the case of an accidental needlestick, immediately wash the area with an antibacterial soap, express blood from the wound, and contact your supervisor. PROCEDURE 1. Identify the patient, two forms of active identification are required.
2. Reassure the patient that the minimum amount of blood required for testing will be drawn. 3. Verify that any diet or time restrictions have been met. 4. Order of Draw
1. Blood Culture 2. Light Blue Top (plasma): 3.2% sodium citrate. These tubes are used for coagulation tests and need to be completely filled to ensure the proper ratio of blood to anticoagulant. 3. Red Top (serum): Plain and gel. Used for chemistry and reference tests. 4. Green Top (plasma): With and without gel, contains lithium heparin. These tubes are used primarily for chemistry tests. 5. Lavender or Pink Top (plasma): Contains EDTA. Used primarily for hematology and blood bank testing. 6. Gray Top (plasma): Contains sodium fluoride/potassium oxalate. Used by chemistry for glucose testing. 7. Yellow Top (plasma and cells): Contains ACD solution A or B. Used for Genetics testing. NOTE: When using a winged blood collection set for venipuncture and a coagulation tube is the first tube needed, first draw a discard tube (plain red top or light blue top). The discard tube does not need to be filled completely. 1. Assemble the necessary equipment appropriate to the patient’s physical characteristics. 2. Wash hands and put on gloves. 3. Position the patient with the arm extended to form a straight-line form shoulder to wrist. 4. Do not attempt a venipuncture more than twice. Notify your supervisor or patient’s physician if unsuccessful. 5. Select the appropriate vein for venipuncture.
6. Apply the tourniquet 3-4 inches above the collection site.
7. Clean the puncture site by making a smooth circular pass over the site with the 70%
8. Perform the venipuncture 1. Attach the appropriate needle to the hub by removing the plastic cap over the small end of the needle and inserting into the hub, twisting it tight. 2. Remove plastic cap over needle and hold bevel up. 3. Pull the skin tight with your thumb or index finger just below the puncture site. 4. Holding the needle in line with the vein, use a quick, small thrust to penetrate the skin and enter the vein in one smooth motion. 5. Holding the hub securely, insert the first vacutainer tube following proper order of draw into the large end of the hub penetrating the stopper. Blood should flow into the evacuated tube. 6. After blood starts to flow, release the tourniquet and ask the patient to open his or her hand. 7. When blood flow stops, remove the tube by holding the hub securely and pulling the tube off the needle. 8. Gently invert each tube
9. DO NOT SHAKE OR MIX VIGOROUSLY. If multiple tubes are needed, follow the proper order of draw 9. Place a gauze pad over the puncture site and remove the needle. 10. Activate the safety device and properly dispose of the vacutainer holder with needle attached into a sharps container. 11. Immediately apply slight pressure to the gauxe pad over the venipuncture site..
12. Tubes must be positively identified after filling with a firmly attached patient label.
13. Observe special handling requirements
VENIPUNCTURE PROCEDURE USING A SYRINGE: 1. Place a sheathed needle or butterfly on the syringe. 2. Remove the cap and turn the bevel up. 3. Pull the skin tight with your thumb or index finger just below the puncture site. 4. Holding the needle in line with the vein, use a quick, small thrust to penetrate the skin and vein in one motion. 5. Draw the desired amount of blood by pulling back slowly on the syringe stopper. Release the tourniquet. 6. Place a gauze pad over the puncture site and quickly remove the needle. 7. Immediately apply pressure. Ask the patient to apply pressure to the gauze for at least 2 minutes. 8. When bleeding stops, apply a fresh bandage, gauze or tape. 9. Transfer blood drawn into the appropriate tubes as soon as possible using a Blood Transfer Device, as a delay could cause improper coagulation. 10. Gently invert tubes containing an additive 5-8 times. 11. Dispose of the syringe and needle as a unit into an appropriate sharps container. INFANT/CHILD PHLEBOTOMY 1. Confirm the patient’s identification 2. Secure patient to Papoose apparatus for stabilization if child is unable to sit upright on their own. 3. Assemble the required supplies 4. Select the collection site and proceed as routine phlebotomy. If the child is old enough, collect blood as in an adult. TROUBLESHOOTING HINTS FOR BLOOD COLLECTION If a blood sample is not attainable: 1. Reposition the needle. 2. Ensure that the collection tube is completely pushed onto the back of the needle in the hub. 3. Use another tube as vacuum may have been lost. 4. Loosen the tourniquet. 5. Probing is not recommended. In most cases, another puncture in a site below the first site is advised. 6. A patient should never be stuck more than twice unsuccessfully by a phlebotomist. The Supervisor should be called to assess the patient. How long should pressure be applied to a venipuncture site?Apply pressure to venipuncture site, have patient maintain pressure for 3-5 minutes with the arm in a straight position, not bent at the elbow. If bleeding has not yet stopped, have the patient raise their arm and maintain pressure.
How do you prevent a hematoma in venipuncture?To prevent a hematoma:. Puncture only the uppermost wall of the vein.. Remove the tourniquet before removing the needle.. Use the major superficial veins.. Make sure the needle fully penetrates the upper most wall of the vein. ... . Apply pressure to the venipuncture site.. How long is needed to hold pressure on the draw site if it is suspected that an artery was nicked?Pressure is applied to the puncture site for 5 to 10 minutes to stop the bleeding. The site will be checked during this time to make sure the bleeding stops.
How long should a venipuncture site be allowed to air dry?The alcohol must be allowed to air dry for approximately one minute prior to venipuncture to properly disinfect site, prevent hemolysis of the specimen, and avoid discomfort for the patient. Gauze should be used when applying pressure to the venipuncture site immediately after the needle is withdrawn.
