Peripheral Nerve Block (Regional Anaesthesia)

A peripheral nerve block, also known as regional anaesthesia, is a technique in which anaesthetic medication is injected around specific nerves to temporarily numb a particular part of the body, such as the shoulder, arm, hand, leg, or foot. It is commonly used for orthopaedic, plastic, and hand surgeries, either alone or in combination with general anaesthesia. By blocking pain signals from reaching the brain, a nerve block provides excellent pain relief during surgery and often for several hours afterwards, reducing the need for strong pain medications. Many nerve blocks are performed using ultrasound guidance, allowing the anaesthesiologist to place the medication accurately and safely. As the anaesthetic wears off, normal sensation and movement gradually return. Your anaesthesiologist will advise you on protecting the numb limb until full feeling and strength have returned, helping ensure a safe and comfortable recovery.
