Post-dural-puncture headache (PDPH) is a complication of puncture of the dura mater (one of the membranes around the brain and spinal cord). [3] The headache is severe and described as "searing and spreading like hot metal", involving the back and front of the head and spreading to the neck and shoulders, sometimes involving neck stiffness .
The signs and symptoms of these may present during a dive, on surfacing, or up to several hours after a dive. The principal conditions are decompression illness (which covers decompression sickness and arterial gas embolism), nitrogen narcosis, high pressure nervous syndrome, oxygen toxicity, and pulmonary barotrauma (burst lung). Although some ...
The epidural syringe is filled with autologous blood and injected in the epidural space in order to close holes in the dura mater. The treatment of choice for this condition is the surgical application of epidural blood patches, [ 27 ] [ 79 ] [ 80 ] which has a higher success rate than conservative treatments of bed rest and hydration.

CT in a person after generalized hypoxia. The brain requires approximately 3.3 ml of oxygen per 100 g of brain tissue per minute. Initially, the body responds to lowered blood oxygen by redirecting blood to the brain and increasing cerebral blood flow. Blood flow may increase up to twice the normal flow but no more.
It is estimated that the likelihood of a dural puncture occurring as a result of epidural catheter placement is 1.5%, with PDPH occurring in as much as 50% of these cases. [6] [3] Dural punctures usually present with a headache or backache within 3 days of the procedure. [13] The headache causes pain over the forehead and the back of the head.
Epidural Subdural Location Between the skull and the inner meningeal layer of the dura mater or between outer endosteal and inner meningeal layer of dura mater: Between the meningeal layers of dura mater and the Arachnoid mater: Involved vessel Temperoparietal locus (most likely) – Middle meningeal artery Frontal locus – anterior ethmoidal ...

Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. [4] When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma .
