Anaesthetic Management of a Known Case of Werner Syndrome by Peripheral Nerve Block in the Orthopaedic Surgery of Forearm.

Werner syndrome (WS) is a rare hereditary disease, characterised by the clinical signs and symptoms of premature ageing. Patients with WS usually have difficult airway due to anatomic malformation of the oral cavity. General anaesthesia with endotracheal intubation poses a high risk for these patients.
