What is an ultrasound nerve block?

Ultrasound-guided nerve block (UGNB) is an extremely useful technique for emergency physicians as a multimodal approach to the acutely injured patient. In the emergency department, UGNBs are an adjunct for pain management and can be an ideal way for clinicians to reduce the overreliance on systemic opioids.

What are the complications of peripheral nerve block?

Serious complications of peripheral nerve blocks include nerve injury, catheter infection, bleeding, and LAST. Intraneural injection occurs frequently with nerve stimulator or ultrasound-guided techniques. It is rarely associated with nerve injury. Lipid emulsion therapy is effective in treating severe LAST.

How bad do nerve blocks hurt?

Will having a nerve block hurt? The placement of a nerve block is associate with minor discomfort. Most patients report that it is less painful than the placement of a small IV catheter.

What can you do with ultrasound guided nerve blocks?

Here, we investigate the untapped potential of torso-based blocks. Explore the use of non-narcotic anesthesia for rib fractures and abdominal procedures. In this chapter, master the use of ultrasound to perform radial, median, and ulnar nerve blocks, image a shoulder dislocation, and perform an intra-articular shoulder injection.

What kind of ultrasound is used for ankle nerve block?

The equipment recommended for an ankle block is: Ultrasound machine with linear transducer (8–18 MHz), sterile sleeve, and gel. Standard nerve block tray. Three 10-mL syringes containing local anesthetic. A 1.5-inch, 22- to 25-gauge needle with low-volume extension tubing.

What do you need to know about nerve block?

Plunge right in with a series of videos that illustrate nerve identification, explain ultrasound probe management, stress the value of preparation, and discuss local anesthetics. This chapter explores the brachial plexus.

What kind of transducer is used for wrist nerve block?

A linear transducer placed at the level of the wrist crease will show the hyperechoic anterior surface of the ulna with shadowing behind; just lateral to the bone and very superficial will be the triangular or oval hyperechoic ulnar nerve, with the pulsating ulnar artery immediately next to it ( Figures 4 and 5 ).
