Venipuncture Grasp the patient's arm firmly using your thumb to draw the skin taut and anchor the vein. Background This case report describes a subclavian vein cannulation that inadvertently led to an arterial puncture with the catheter tip radiologically seen at the level of the aorta. 1 Over a 2-year period, Newman reported 12 cases of arterial puncture during blood donation from 410 000 blood donors. 3 Although this is small, cannulation of the cephalic vein is probably one of the most frequent events in routine anaesthesia, so the absolute number of patients who might sustain accidental puncture of a superficial radial artery may be high. In a venipuncture procedure, the cephalic vein is often the vein of choice for many clinicians. Situations That Affect the Quality of the Specimen Accidental Arterial Puncture It is important for phlebotomists to be able to differentiate between veins and arteries. Select a suitable site for venipuncture. Site for Venipuncture or Arterial Puncture. This can cause discomfort and pain and can complicate further collections from that site. accidental arterial puncture • the brachial artery is located near the basilic vein; it is possible for the phlebotomist to puncture this artery accidentally. Patient safety. False aneurysm development following accidental arterial puncture is a rare event but has been well described in the literature. 14. This order of draw should be followed whenever multiple tubes are drawn during a single venipuncture. This is more common in humeral and femoral punctures than radial punctures. However, failure to recognize the arterial puncture can result in subsequent placement of a large-bore catheter into an artery, ranging from 0.1% to 1.0% of attempted CVC placements in reported series. More on accidental arterial cannulation after attempted central venipuncture. 2 From these, 4 developed haematoma, and 1 developed a false aneurysm. if an accidental arterial puncture occurs during the venipuncture procedure? Caused by blood leaking from a blood vessel during or following venipuncture. Capillary procedures may also be safer for patients at risk of developing iatrogenic anemia (anemia induced by diagnostic blood sampling). The radial nerve passes along the thumb side of the arm, from the shoulder down into the wrist area, and is in close proximity to the cephalic vein. This procedure is without complications, which sometime can be fatal. It is critically necessary to release the … Select the site 6. rapidly forming hematoma, rapid filling tube, and bright red blood), discontinue the venipuncture immediately. Soon after venipuncture and after insertion of the micro-guidewire, the intravascular location of the wire and its direction should be checked, using the same linear probe utilized for venipuncture. Confirmation is carried out . A hematoma can result from an injury to any type of blood vessel (artery, vein, or small capillary).

Choose the right equipment. ARTERIAL PUNCTURE Probing and lateral movement of the needle particularly near the basilic vein are the main causes of accidental arterial puncture. Arterial puncture is when the needle in inserted into an artery rather than a vein. Signs of suspected arterial puncture include noting bright red blood with pulsatile flow, blood column moving upwards in the tubing of an infusion set, intense pain and distal ischaemia. Most commonly, hematomas are caused by an injury to the wall of a blood vessel, prompting blood to seep out of the blood vessel into the surrounding tissues. Venipuncture is just that, puncturing the vein. Pain . The sample can be obtained either through a catheter placed in an artery, or by using a needle and syringe to puncture an artery. .

Early and late complications are most often caused by inadequate clinical decision-making at the time of PICC insertion, with examples such as the avoidance of US-guided venipuncture which may increase the risk of accidental arterial puncture, nerve injury, or patient injury; failure to verify correct location of the tip may increase the risk . The patient is asked to make a fist. Complications that can arise from venepuncture include haematoma formation, nerve damage, pain, haemaconcentration . One of the common problems encountered in percutaneous puncture of the IJV is accidental puncture of the surrounding major artery. The blood collector must ask the patient to breathe deeply and slowly. Hematoma: Blood can leak out of a vein and under the skin during venipuncture. 2. Any attempt to repeat a puncture at the same site increases the risk of complications. Swiftly insert the needle through the skin and into the lumen of the vein. Signs and symptoms include a pulsating mass with a palpable thrill and associated bruit.

He said it was fine but that he needed to be laying down. • Hematoma - presence of hematoma indicates that blood has accumulated in the tissue surrounding a vein during or following venipuncture. Next. Properly position the needle within the vein. This is more common in humeral and femoral punctures than radial punctures. The patient should be reassured and made as comfortable as possible. A channel forms between the lacerated vein and artery immediately post- venipuncture or as part of the healing process. Arterial injury may be a potentially lethal problem of serious bleeding or large hematoma. . To avoid arterial puncture or pneumothorax during subclavian venipuncture, needle insertion technique is important.
