Post lumbar puncture headache: diagnosis and management.

Lumbar puncture is a frequently performed procedure in medical emergencies and anaesthesia. Headache after lumbar puncture is a common occurrence (32%) and carries a considerable morbidity, with symptoms lasting for several days, at times severe enough to immobilize the patient. If untreated, it can result in serious complications such as subdural haematoma and seizures, which could be fatal. Certain factors contribute to the development of headache after lumbar puncture. If these factors are taken into consideration, the incidence of headache could be markedly reduced. It is therefore important that the doctors are aware of the methods available for reducing the incidence of headaches after lumbar puncture. On the other hand, there are several misconceptions that are thought to decrease the incidence of headaches with no scientific basis. This article reviews the scientific literature and highlights the practical issues involved in the diagnosis and management of headaches after lumbar puncture, including the epidural blood patch treatment.
