It is a method for the identification of the epidural space, a potential space. As a needle is advanced through the ligamentum flavum, to the epidural space, with constant pressure applied to the piston of a syringe, loss of resistance occurs once the needle enters the epidural space due to the change in pressure.
Odom's indicator is a device used for locating the epidural space in regional anaesthesia. [1] The device works on Dogliotti's principle [2] by finding an area of decreased resistance to injection. It was originally designed on the assumption that the pressure in the epidural space was negative. This device is no-longer popular and alternative ...
Unlike the cranial epidural space, the spinal epidural space contains adipose tissue, the internal vertebral venous plexuses and the spinal nerve roots. [1] The spinal epidural space spans the length of the spinal cord, from the foramen magnum superiorly to the sacral hiatus inferiorly. [6] Epidural space is the smallest at the cervical region ...
In patients who are at high risk of developing caries i.e. patients who have to undergo general anaesthesia for dental treatment due to rampant caries. [24] To protect and restore teeth that may have extensive tooth tissue loss due to erosion, attrition or abrasion. [22] As a support for some dental appliances e.g. space maintainers [22]
The first described placement of a lumbar epidural catheter was performed by Manuel Martínez Curbelo (5 June 1906–1 May 1962) on January 13, 1947. [26] [27] Curbelo, a Cuban anesthesiologist, introduced a 16 gauge Tuohy needle into the left flank of a 40-year-old woman with a large ovarian cyst.
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
Saline (also known as saline solution) is a mixture of sodium chloride (salt) and water. [1] It has a number of uses in medicine including cleaning wounds, removal and storage of contact lenses, and help with dry eyes. [2] By injection into a vein, it is used to treat hypovolemia such as that from gastroenteritis and diabetic ketoacidosis.
Tooth preparation and the associated loss of coronal tissue can risk further insult to the pulp and limit the options for future restoration replacement. [2] An alternative approach is to create the necessary space by reorganising the occlusion by means of an arbitrary increase of the vertical dimension of occlusion, i.e. the use of a dahl ...
