The anaesthetic management of a patient with tuberous sclerosis undergoing two-stage scoliosis surgery is described. The patient suffered from severe mental retardation, seizures and facial angiofibromas. General anaesthesia using isoflurane and nitrous oxide in oxygen, supplemented with opioid analgesia and hydralazine, and labetalol to induce hypotension, appeared to be satisfactory. Postoperative recovery was delayed and complicated by pleural effusion, sputum retention and mild seizures. Tuberous sclerosis is an autosomal dominant disease well known for its neurocutaneous manifestations. Other organs such as the heart, lungs and kidneys may be involved. The potential problems in the anaesthetic management of a patient with tuberous sclerosis are discussed.
