Indications And Complications

Peripheral nerve blocks of the upper limb can provide excellent anaesthesia and postoperative analgesia. A variety of well-established traditional approaches to the brachial plexus exist, namely interscalene, supraclavicular, infraclavicular, and axillary techniques. Individual terminal nerves such as the median, radial, ulnar, and other smaller nerves can also be blocked more distally. The traditional and ultrasound-guided approach to each of these nerve blocks is discussed in turn in this chapter, along with specific indications and complications. The introduction of ultrasound guidance has generated significant excitement in this field in the last 10 years and has been demonstrated to improve efficacy and reduce complications. However, a sound knowledge of anatomy of the nerve supply to the upper limb remains essential during any upper limb regional anaesthesia technique.

Ultrasonic Image

A new ‘texturing method’ has been developed for nerve block needles in an attempt to improve the ultrasonic image of the needles. Using a synthetic phantom, these textured needles were compared to currently available needles. The textured needle had improved visibility under ultrasound. This type of needle may assist the anaesthetist perform ultrasound-guided regional anaesthesia.

Life Threatening

There are a number of important emergencies associated with regional anaesthesia that the anaesthetist should be aware of. Life-threatening emergencies, such as local anaesthetic systemic toxicity leading to cardiorespiratory arrest can occur irrespective of the site of local anaesthetic infiltration. Specific procedures including epidural and spinal anaesthesia, eye blocks, and peripheral nerve blocks cause a range of surgical emergencies and severe complications. Neuraxial anaesthesia carries the risk of epidural haematoma and abscess while infiltration or local anaesthetic around the globe carries the risk of both retro-orbital haematoma and globe perforation, all of which may require urgent surgical intervention. Although literature supports the safety of low concentration (1 in 200 000) adrenaline as an additive to digital blocks, inadvertent injection of higher concentrations may have the potential for ischaemic injury. Finally, the assessment and diagnosis of perioperative nerve injuries when associated with a peripheral nerve block present a formidable clinical challenge.
