What nerves do you need to be aware of when taking blood from the antecubital fossa?
The median nerve “runs inside the antecubital fossa and passes through the forearm into the palm of the hand” which can make blood draw in the area of the antecubital fossa challenging. Clinicians should avoid these areas when possible.
What should you do if you hit a nerve during venipuncture?
Unless it becomes infected (worsening pain and redness), ice packs and anti-inflammatory medications, such as Ibuprofen, are recommended. It should clear up in a few days, but if it does not, you might want to see a doctor. A more serious injury from a blood draw is nerve damage.
How do you draw blood from the median cubital vein?
Insert the needle at a 15 to 30-degree angle into the vessel.
- If properly inserted blood should flash into the catheter.
- Attach the needed tubes or syringes to remove the proper volume of blood.
- Remove the needle from the patient’s arm and press down on the vessel with gauze.
Which areas must be avoided for venipuncture?
Certain areas are to be avoided when choosing a site: Extensive scars from burns and surgery – it is difficult to puncture the scar tissue and obtain a specimen. The upper extremity on the side of a previous mastectomy – test results may be affected because of lymphedema. Hematoma – may cause erroneous test results.
Which vein is closest to median nerve?
The median cubital vein passes anterior to the bicipital aponeurosis, below which lie the brachial artery and median nerve. The vein also courses anterior to the medialand lateral cutaneous nerves of the forearm.
Why is the median cubital vein used for venipuncture?
Of these three veins, the preferred one for venipuncture is the median cubital vein because it is larger and has a lower tendency to move or roll when the needle is inserted. There are also fewer nerve endings surrounding this vein making venipuncture less painful at this site.
Can a phlebotomist damage a nerve?
Background. Venipuncture is one of the one of the most commonly performed, minimally-invasive procedures; however, it may lead to peripheral nerve injury.

Why is median cubital vein preferred for venipuncture?
Which vein is preferred by most phlebotomists?
median cubital vein
Of these, the median cubital vein is usually the vein of choice for phlebotomy: It is typically more stable (less likely to roll), it lies more superficially, and the skin overlying it is less sensitive than the skin overlying the other veins. Antecubital veins, right arm. Antecubital veins, left arm.
Which vein in the antecubital area should not be used for phlebotomy?
Which vein in the antecubital area should not be used in phlebotomy? The basic vein because it lies on the inside of the anticubital area and is close to the brachial artery and median nerves.
How do you know if a needle hit a nerve?
Pain is the most frequent symptom of a nerve injury. It is usually described as a severe shooting or burning sensation at the injection site with radiation to the dorsum of the forearm and hand. Patients could also present numbness, paresthesia, hypoesthesia and other sensory disturbance.
How long does nerve damage take to heal after blood draw?
The majority of these injuries are self-limiting and resolve spontaneously. Newman and Waxman found that 70, 90, and 96% of venipuncture-related nerve injuries resolve within 1, 2 and 6 months, respectively. However, chronic disabling deficits have been reported at an incidence of 1 in 1.5 million phlebotomies.
What are four most common problems that occur with a venipuncture?
Serious complications were defined as cellulitis, phlebitis, diaphoresis, hypotension, near syncope, syncope, and seizure activity. Results: Minor bruising and hematoma were fairly common, involving 12.3% of venipunctures, with minor bruising being the most common reaction.
What are 5 complications of venipuncture?
Complications that can arise from venepuncture include haematoma formation, nerve damage, pain, haemaconcentration, extravasation, iatrogenic anaemia, arterial puncture, petechiae, allergies, fear and phobia, infection, syncope and fainting, excessive bleeding, edema and thrombus.
How long can you leave a tourniquet on for venipuncture?
Never leave the tourniquet on for longer than one (1) minute. To do so may result in either hemoconcentration or a variation in blood test values.
Which vein is the first choice for venipuncture?
The median cubital vein is the larger and more stable vein and is preferred for venipuncture. The cephalic and basilic veins have a greater tendency to roll and veinpuncture may be more painful from these sites.
Which vein is the median nerve closest to?
Ohnishi et al.16 reported that the median nerve was located on the ulnar side of the brachial artery at the level of the elbow crease. Moreover, Kimori et al. showed that the lateral antebrachial cutaneous nerve descended along the deep layer of the cephalic vein.
Why is median cubital vein preferred?
What happens if they hit a nerve when drawing blood?
Direct puncture nerve injury usually causes immediate symptoms, including: sharp acute pain at venipuncture site. sharp shooting pain up or down the arm. sensation of pain that changes in severity depending on needle position.

- bleeding has restarted.
- swelling that is large or increasing in size.
- numbness or pins and needles in the arm, hand or fingers.
- severe or worsening pain.
- coldness or paleness of the lower arm, or hand of the affected arm.
Why should a tourniquet be removed within 1/2 minutes?
The phlebotomist should not leave the tourniquet on the patient’s arm for longer than a minute. This increased pressure against the vessel walls allows plasma and small molecules to flow through capillary walls and into the tissue.
What vein is in the antecubital fossa?
The median cubital vein (antecubital vein) is a prominent superficial upper limb vessel. Its location is in the cubital fossa, on the anterior/flexor aspect of the elbow joint. This region of the upper limb is sometimes referred to as the antecubital area.
