Occipital nerve block is a procedure involving injection of steroids or anesthetics into regions of the greater occipital nerve and the lesser occipital nerve used to treat chronic headaches. These nerves are located in the back of the head near in the suboccipital triangle along the line between the inion and the mastoid process .
Local anesthetic is applied to the back of the neck and a Tuohy needle is advanced towards the location of the greater occipital nerve and lesser occipital nerve under fluoroscopic guidance. [8] [9] [10] When the location is confirmed, a temporary lead is placed through the needle before the needle is carefully removed.
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.

Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
Caudal anaesthesia is a relatively low-risk technique [4] commonly used, either on its own or in combination with sedation or general anaesthesia. [3] [5]Caudal anesthesia may be favored for sub-umbilical region surgeries in the pediatric population, such as inguinal hernia repair, circumcision, hypospadias repair, anal atresia, or to immobilise newborns with hip dysplasia.
Doctors and specialists at the Murdoch Children's Research Institute in Melbourne, Australia, are studying and reprogramming the potential of the blood to treat heart failure in children.
Odom's indicator is a device used for locating the epidural space in regional anaesthesia. [1] The device works on Dogliotti's principle [2] by finding an area of decreased resistance to injection.
