Sir Lumbar puncture (LP) is an essential medical procedure for several clinical conditions. It is an invasive procedure by which physicians can provide sample of cerebrospinal fluid through a needle inserted into the lower lumbar area for diagnostic purposes (meningitis or subarachnoid hemorrhage). Injection of medications into the cerebrospinal fluid "intrathecally", particularly for spinal an...

The developments of new spinal needles and needle tip designs have reduced the incidence of postdural puncture headache (PDPH). Although it is clear that reducing the loss of CSF leak from dural puncture reduces the headache, there are areas regarding the pathogenesis, treatment, and prevention of PDPH that remain controversial. Air travel by itself may impose physiological alteration in centra...

Postdural puncture headache (PDPH) has been a problem for patients, following dural puncture, since August Bier reported the first case in 1898. His paper discussed the pathophysiology of low-pressure headache resulting from leakage of cerebrospinal fluid (CSF) from the subarachnoid to the epidural space. Clinical and laboratory research over the last 30 years has shown that use of small-gauge ...

A 29-YR-OLD healthy parturient developed positional frontoparietalheadacheafteraccidentalduralpuncture during attempted placement of an epidural catheter. The headache improved with hydration, bed rest, and analgesics. However, it persisted (without postural component) at the 2week interval. Neurologic examination was normal. Magnetic resonance imaging showed the presence of bilateral frontopar...
