Lumbar plexus block
Inguinal perivascular block (three-in-one block) Perspective The inguinal perivascular block is based on the concept of injecting local anesthetic near the femoral nerve in an amount sufficient to track proximally…
Lateral femoral cutaneous nerve block
Key Points • This block can be used to provide postoperative analgesia following hip surgery, upper lateral thigh skin grafting, and neurolysis for refractory meralgia paresthetica. • Combined with other…
Ultrasound for fascia iliaca and inguinal region blocks
Key Points • A high-frequency linear transducer is preferred for this block. • The fascia iliaca compartmental block (FICB) can be used as an alternative anterior approach to the lumbar…
Sciatic block
Perspective The sciatic nerve is one of the largest nerve trunks in the body, yet few surgical procedures can be performed with sciatic block alone. It is combined most often…
Lower extremity block anatomy
Key points • Unlike the upper extremity, there are two nerve plexuses innervating the lower extremity; the lumbar plexus innervates the ventral aspect, whereas the lumbosacral plexus primarily innervates the…
Intravenous regional block
Key points • Intravenous (IV) regional anesthesia is usually achieved using dilute lidocaine 0.5%; 50 mL of prilocaine has also been used successfully. • The IV regional block is useful…
Distal upper extremity blocks
Key points • Blockade of peripheral nerves of the upper extremity is often accomplished by brachial plexus approaches. However, conditions such as infections to brachial plexus sites, coagulopathy, single nerve…
Axillary block
Perspective Axillary brachial plexus block is most effective for surgical procedures distal to the elbow. Some patients can undergo procedures on the elbow or lower humerus with an axillary technique,…
Infraclavicular block
Perspective Infraclavicular brachial plexus block is useful for both single-injection and continuous infusion techniques. This technique results in a sensory and motor block similar to a traditional axillary approach, albeit…
Supraclavicular block
Perspective Supraclavicular block provides anesthesia of the entire upper extremity in the most consistent, efficient manner of any brachial plexus technique. It is the most effective block for all portions…
