Facilitation of the drainage of secretions from dilated bronchi of the LUNGS. The patient lies on an inclined plane, head downwards, and is encouraged to cough up as much secretion from the lungs as possible. The precise position depends on which part of the lungs is affected. It may need to be carried out for up to three hours daily in divided periods. It is of particular value in BRONCHIECTASIS and lung abscess (see LUNGS, DISEASES OF).... postural drainage
an increasingly recognized type of persistent headache in a patient with no history of headaches. Features include headache that is worse on standing and resolves on lying flat. It may be associated with other symptoms, such as dizziness, tinnitus, and (rarely) *diplopia. The commonest cause is a complication of lumbar puncture, but it may occur spontaneously (spontaneous intracranial hypotension) after a dural tear resulting in a leak of cerebrospinal fluid. Treatment is with bed rest and increased intake of fluids; caffeine orally or intravenously is also used. In cases that do not resolve, an epidural blood patch procedure is performed, in which a small quantity of the patient’s blood is slowly injected into the *epidural space to seal the leak.... intracranial hypotension headache
