Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
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 .
A small dose of local anaesthetic (e.g. bupivacaine) is then instilled. An opioid such as fentanyl may also be given if desired. The spinal needle is then withdrawn and the epidural catheter inserted in the standard manner. Alternatively, a two-level approach may be undertaken. The epidural space is first located in the standard manner.
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. [1] It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. The material absorbing the radiation can be human tissue, air, water, or any other substance.
Epidural steroid injection (ESI) is a technique in which corticosteroids and a local anesthetic are injected into the epidural space around the spinal cord in an effort to improve spinal stenosis, spinal disc herniation, or both. It is of benefit with a rare rate of major side effects.
[9] [10] Electron IORT has the advantages of being able to carefully control the depth of radiation penetration while providing a very uniform dose to the tumor bed. Applied with energies in the range of 3 MeV to 12 MeV, electron IORT can treat to depths of up to 4 cm over areas as large as 300 cm² (i.e. a 10 cm diameter circle) and takes only ...
The concept of the rem first appeared in literature in 1945 [17] and was given its first definition in 1947. [18] The definition was refined in 1950 as "that dose of any ionizing radiation which produces a relevant biological effect equal to that produced by one roentgen of high-voltage x-radiation."
Trimix is a combination of three drugs: alprostadil, papaverine, and phentolamine. These medications work in combination to increase blood flow to the penis, resulting in an erection. [1] [2] [3] Alprostadil is a prostaglandin vasodilator that allows more blood to flow into the area by relaxing the smooth muscle in the blood vessels of the penis.
