MCQ MAHE 2000 Anesthesia Answer 4

The Correct Answer is B

A caudal anesthesia is administered by a catheter inserted through the sacral hiatus. Anesthetic is placed in the catheter, and the anesthetic bathes the sacral nerve roots. The catheter is in the epidural space, and this is where the anesthesia is placed.

The central canal of the spinal cord is a space in the spinal cord through which CSF circulates. The dural sinuses are venous sinuses found in the brain--this is where blood drains from the brain. The subarachnoid space is found under the arachnoid mater; this is the space where the cerebrospinal fluid circulates around the spinal cord. Finally, the subdural space is a space between the dura and arachnoid mater--this is a potential space only!

when a caudal anesthesia is given what happens is the needle is inserted into the sacral hiatus and the injected anesthesia fills up the epidural space and will diffuse up into the nerves which are passing through this space especially the sacral nerves which being distributed to the woman’s perineum, external genitalia, and lower uterus.
