In recent years, the USG-guided brachial plexus block has revolutionized regional anesthesia practices. The term USG stands for Ultrasound Guidance, providing unparalleled precision and safety in anesthetic procedures. This technique primarily targets the brachial plexus, a crucial network of nerves responsible for motor and sensory functions in the upper limb.

Understanding the Brachial Plexus

Before delving into the specifics of an Ultrasound-guided brachial plexus block, it is essential to comprehend the anatomy of the brachial plexus.

• The brachial plexus consists of roots, trunks, divisions, cords, and branches.
• Located in the neck and shoulder region, it innervates the arm, forearm, and hand.

Why Opt for an Ultrasound-guided Brachial Plexus Block?

There are several advantages of using USG for brachial plexus blocks:

1. Increased Precision: Real-time imaging allows for accurate placement of the needle.
2. Reduced Complications: Lower risk of damaging surrounding structures such as blood vessels and lungs.
3. Enhanced Patient Comfort: The precise administration of anesthesia ensures effective nerve block with minimal discomfort.

Techniques in Ultrasound-guided Brachial Plexus Block

Different approaches to the USG-guided brachial plexus block can be employed depending on the surgical site and patient anatomy. The common techniques include:

1. Interscalene Block

This technique targets the roots/trunks of the brachial plexus, ideal for shoulder surgeries.

2. Supraclavicular Block

Perfect for surgeries involving the distal arm, this approach blocks the brachial plexus primarily at the level of trunks/divisions.

3. Infraclavicular Block

Used for elbow, forearm, and hand surgeries, targeting the cords of the brachial plexus.

4. Axillary Block

Administered around the terminal branches, suitable for procedures on the forearm and hand.
