Anaesthesia for shoulder surgery
- 1. Regarding the innervation of the shoulder:
- Shoulder surgery can be carried out using brachial plexus block alone.
- The supraclavicular nerves arise from the lower trunk of the brachial plexus.
- The suprascapular nerve innervates a significant part of the shoulder joint.
- Cutaneous analgesia over the shoulder region is a reliable sign of successful block.
- The axillary nerve is reliably blocked using an axillary brachial plexus block.
- 2. Regarding interscalene block:
- Can be used as the sole anaesthetic technique for shoulder surgery.
- Requires a distal motor response with a peripheral nerve stimulator to provide a successful block.
- May occasionally cause total spinal anaesthesia.
- Will invariably cause hemidiaphragmatic paresis.
- Is suitable for ultrasonic location.
- 3. Regarding shoulder surgery:
- Neurological injuries as a result of surgery are extremely rare.
- The Bezold–Jarisch reflex may cause intraoperative hypertension.
- Brachial plexus bock
