sub·du·ral space

[TA]
originally thought to be a narrow fluid-filled interval between the dural and arachnoid; now known to be an artificial space created by the separation of the arachnoid from the dura as the result of trauma or some ongoing pathologic process; in the healthy state, the arachnoid is tenuously attached to the dura and a naturally occurring subdural space is not present.

subdural space

Etymology: L, sub, beneath, dura, mater, hard mother, spatium
the potential space between the dura mater and the arachnoid membrane.

sub·dur·al space

(sŭb-dūr'ăl spās) [TA]
An artificial space created by the separation of the arachnoid from the dura as the result of trauma or some pathologic process; in the healthy state, the arachnoid is tenuously attached to the dura and a naturally occurring subdural space is not present.

space

1. a delimited area.
2. an actual or potential cavity of the body.
3. the areas of the universe beyond the earth and its atmosphere.

dead space
1. space remaining in tissues as a result of failure of proper closure of surgical or other wounds, permitting accumulation of blood or serum.
2. the portions of the respiratory tract (passages and space in the alveoli) occupied by gas not concurrently participating in oxygen-carbon dioxide exchange.

8,9,17,18) However, the use of the neurostimulator has been considered useful because a response below 1mA when the localization is in the subdural space gives a diffuse response with the involvement of multiple dermatomes, while if the localization is in the epidural space with stimuli between 1 and 10 mA, the responses obtained will correspond to the dermatome where the needle is placed.
However, disease spread to the subdural space is extremely rare, occurring in less than 1% of patients with metastatic disease.
The subdural space is a narrow potential space between the arachnoid mater and the dura mater containing a minute quantity of serous fluid (10).
The spinal subdural space has greater potential capacity dorsally and laterally (12).
Using electron microscopy, the anatomy of the subdural space was observed by Reina et al (16), wherein the arachnoid mater had an outer compact laminar portion attached to the inside of the dural sac and a separate inner trabeculated portion.
According to their findings, up to 7% of epidural needles may be partly placed in the subdural space during the performance of an epidural block (25).
During subarachnoid anaesthesia the dura mater is intentionally pierced, with the subdural space being traversed before piercing the arachnoid mater.
For the treatment of intractable cervical pain, Mehta and Maher (10) injected local anaesthetic in the subdural space; they rotated the epidural needle through an arc of 180[degrees] along with gentle pressure to enter the subdural space.
Any attempt to inject local anaesthetics at the same intervertebral space may cause deposition in the subdural space (31).
The onset of the block is somewhat intermediate between that of a subarachnoid and epidural block, because the nerves in the subdural space are covered with pia and arachnoid maters, as compared to the subarachnoid space where the nerves are sheathed by pia mater only and the epidural space where arachnoid, pia and dura mater envelop the nerves.
This unexpectedly revealed even larger subdural spaces with clear evidence of subdural bleeds of different ages.
