The procedure is most often used to relieve PDPH following an epidural injection or lumbar puncture. Diagram of epidural catheter placement.

Factors such as pregnancy ...

The test involves removing 30–50 ml of CSF through a lumbar puncture, after which motor and cognitive function is clinically reassessed. [1] The name "Fisher test" is after C. Miller Fisher , a Canadian neurologist working in Boston, Massachusetts, who described the test.
Caudal anaesthesia is a relatively low-risk technique [4] commonly used, either on its own or in combination with sedation or general anaesthesia. [3] [5]Caudal anesthesia may be favored for sub-umbilical region surgeries in the pediatric population, such as inguinal hernia repair, circumcision, hypospadias repair, anal atresia, or to immobilise newborns with hip dysplasia.
It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra. The dura is pierced with a needle during a lumbar puncture (spinal tap).
Ultrasound-guided lumbar puncture is a medical procedure used in some emergency departments to obtain cerebrospinal fluid for diagnostic purposes. In contrast to standard lumbar puncture by palpation , the use of ultrasound imaging may reduce the number of failed punctures, needle insertions, and needle redirections. [ 1 ]
A lumbar puncture can give the symptom of a post-dural-puncture headache. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. [5] A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak.
