Basic Principles of Brachial Plexus Block

  • The brachial plexus is a bundle of nerves that innervates the arm and hand.
  • A brachial plexus block is a regional anesthesia technique that involves injecting a local anesthetic into the brachial plexus to provide anesthesia to the arm and hand.
  • The brachial plexus is located at the base of the neck, and the block can be performed at either the cervical or thoracic level.
  • The brachial plexus block provides temporary relief of shoulder pain.

Axillary Brachial Plexus Block Indications

Axillary brachial plexus block is indicated for persistent pain proximal to the elbow, ipsilateral shoulder, or arm. This block can be performed after an acute axillary brachial plexus block has failed, with only local anesthetics providing relief.

Axillary brachial plexus block is also indicated for recurrent pain after a failed axillary, supraclavicular block. A positive axillary brachial plexus block is variable and may be affected by previous trauma or surgery, injections, local anesthetic potency, and needle placement.

Techniques of Axillary Block

The axillary block is a type of regional anesthesia used to numb the arm and hand. This block is usually performed with a local anesthetic, such as lidocaine or bupivacaine. The axillary block can be achieved with either a needle and syringe or a catheter. The hand and syringe method is used more often as it is less invasive and has a lower risk of complications.

The axillary block is usually performed with the patient lying on their side or sitting up. The area to be purified is cleansed with an antiseptic solution, and a local anesthetic is injected into the tissue surrounding the axillary nerve.

An axillary block is performed to prevent regional pain syndrome in patients with breast cancer and improve postoperative analgesia quality.

The technique of axillary block is performed in the outpatient clinic before the operation or two to seven days after the procedure in patients with breast cancer.

In this case, the block does not cause additional discomfort. The duration of the procedure is 1-2 minutes. There is a slight discomfort in the shoulder during the procedure, developing a minor swelling.

Performance of Axillary Block under Ultrasound Guidance

The ultrasound-guided axillary block is a safe and effective technique for providing regional anesthesia.

This systematic review was undertaken to evaluate the performance of ultrasound-guided axillary blocks in terms of success rates, complications, and other relevant outcomes.

An overall of 25 studies was included in this review, which involved 2,238 patients. The overall success rate for ultrasound-guided axillary blocks was 96.7%. Complications were rare, and most were minor. Ultrasound-guided axillary blocks are a safe and effective technique for providing regional anesthesia.

Axillary block procedure 

Axillary block procedure is a minor surgical procedure used to numb the nerves in the arm. It is typically used as pain relief during medical procedures or childbirth.

An axillary block is a small piece of plastic that is usually less than 3 inches long. It is inserted underneath the skin of the top arm. This block controls pain during specific procedures. There are several different types of blocks.

  • A normal block (nerve block) reduces pain by numbing the nerves traveling from the arm to the hand.
  • A test block (somatic block) numbs the arm and any related muscles. This test block is only used to discover the location of the nerves, and nerves do not control movement.
  • An ultrasound-guided block (ultrasound block) reduces pain during an operation. The block usually lasts more than 24 hours. The numbing medicine is injected using a strong, concentrated dose of ultrasound. This particular type of block is used when other block types are not an option.

A complication of Axillary block

Axillary block complications are relatively rare but can include nerve injury, hematoma formation, and infection. Complications are more familiar with higher-volume blocks and using a catheter.

  • Infection

Infection of the axilla is a rare but well-known complication of an axillary block. It is attributed to contamination of the sterile field with surrounding skin flora, bacteria colonizing the skin, or bacteria growing in the catheter hub or the injection port. The incidence of infection has been estimated at 0.4% of axillary block cases. The presumed pathophysiology is similar to that of catheter-related infection of other sites. The infection leads to inflammation, abscess formation, and drainage into the axilla or onto the skin surface.

  • Bleeding or hematoma formation

An axillary block is a common regional anesthesia technique used to anesthetize the upper limb for surgical procedures. Blood loss during axillary block is a rare but potential complication. When a significant vessel is lacerated, the artery may bleed profusely and is prone to hematoma formation. Patients who are elderly, diabetic, or anti-coagulated are at higher risk of bleeding.

  • Accidental intravascular injection

An accidental intravascular injection is a complication of an axillary block. The incidence of this complication is between 1% and 10% of the total blocks. It results from an injection of the local anesthetic agent into a blood vessel rather than a nerve. It is caused by the inherent difficulty in identifying anatomy in the axillary region. The most typical site of injection is the axillary artery. A local anesthetic agent injected into a vessel may cause unwanted cardiovascular, neurological, or cutaneous symptoms.

  • Local anesthetic systemic toxicity

Local anesthetic systemic toxicity (LAST) is an infrequent but severe adverse reaction of local anesthesia. It is characterized by the rapid onset of symptoms related to the central nervous system after regional anesthesia with single or multiple local anesthetics.

How do you test an axillary block?

The axillary block is a regional anesthesia technique used to numb the arm and hand. The axillary block injects a local anesthetic into the space between the shoulder and the arm.

An axillary block is an anesthesia technique for carrying surgery that blocks the nerves that supply your arm. With a simple injection of local anesthetic, the surgeon can block the nerves that supply your arm, which is needed for certain surgeries.

The test of an axillary block is the “5-5-5” test. To perform the “5-5-5” test, the surgeon must create a block in your arm. The surgeon must inject the administrator in five different spots at five different levels in your arm. The surgeon must wait one minute after each injection.

Disadvantages of Axillary Block

  • The block is not easily reproducible.
  • The block is difficult to place in obese or non-cooperative patients or patients with brachial plexus injury.
  • The block is limited to the axilla.

What are the risks of an Axillary Brachial Plexus Block?

A first axillary brachial plexus block has a low risk (1%), but subsequent blocks carry a slightly higher risk (3-4%). Complications may include bleeding, infection, or nerve damage (paralysis) at the injection site.

The axillary plexus block is an anesthetic technique that involves injecting a local anesthetic and a steroid medication into the axillary space (the armpit). The local anesthetic blocks the pain receptors in the shoulder, arm, and hand, rendering them numb. Because steroids weaken the inflammation, they reduce the swelling.

The risks of the axillary plexus block include:

  • allergic reactions to the local anesthetic or steroid medication
  • infection at the injection site
  • nerve damage to the shoulder, arm, or hand
  • damage to nearby structures, such as arteries or nerves
  • bleeding at the injection site
  • damage to the axillary nerve, which supplies feeling to the armpit
  • injury to surrounding tissue or nerves
  • numbness and tingling in the upper extremity
  • temporary or permanent nerve damage in the shoulder, arm, or hand
  • loss of feeling in the shoulder, arm, or hand

How long does it take to recover from an Axillary Brachial Plexus block?

How long does it take to recover from an Axillary Brachial Plexus block

How long does it take to recover from an Axillary Brachial Plexus block

This depends on the individual, but typically it takes anywhere from a few days to a week for most of the numbness and tingling to dissipate. However, some may experience residual numbness and weakness for several weeks or months.

Most medical professionals feel that it takes about 4-6 weeks to recover from an Axillary Brachial Plexus Block fully. Usually just over four weeks.

FAQ

Which nerves are blocked in an axillary block?

An axillary block is pain relief of the upper limb. Block is usually performed on the axillary nerve.

For what procedures is an axillary brachial plexus block best suited?

An axillary brachial plexus block is best suited for procedures that require anesthesia or analgesia of the arm, such as surgery or certain types of pain management.

How long do axillary blocks last?

It depends on some factors, including the type of axillary block used, the individual’s response to the block, and the reason for the block in the first place. In general, however, most axillary blocks last for several hours, with some lasting for a full day or even longer.

How do you test an Axillary Brachial Plexus Block?

The axillary brachial plexus block is tested by using a rapid injection of local anesthetic through two needles inserted on either side of the clavicle into the axilla and brachial plexus. A loss of motor or sensory function of the arm indicates a successful block.

Does brachial plexus block require imaging?

Yes. A brachial plexus block usually requires imaging to ensure the needle is in the correct location. If the block is unsuccessful, imaging can help determine why.

How do you assess a brachial plexus block?

The most appropriate way to assess if a patient has had a brachial plexus block is to palpate the radial nerve. If a patient has no radial sensation, the block is likely incomplete. A normal radial nerve should be well innervated.

What does an Axillary Brachial Plexus Block cover?

Axillary brachial plexus blocks are surgical procedures performed on patients with a painful shoulder and arm conditions. Specifically, blocks are used for the shoulder, elbow, wrist, forearm, and fingers.

Any axillary nerve procedure is considered an axillary brachial plexus block. Axillary brachial plexus blocks are performed by placing a needle in close proximity to the nerve.

How do you put in axillary blocks?

An axillary block is a local anesthetic injection around the shoulder region. You first need to locate the person’s shoulder to put it in. Next, you can move your arms back behind your back. Next, you place the syringe in the armpit.

When the arm returns to its normal position, you push the syringe down to push the local anesthetic down into the shoulder joint.
