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 The spinal needle is then withdrawn and the epidural catheter inserted in the standard manner.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.
Radioimmunotherapy (RIT) uses an antibody labeled with a radionuclide to deliver cytotoxic radiation to a target cell. [1] It is a form of unsealed source radiotherapy.In cancer therapy, an antibody with specificity for a tumor-associated antigen is used to deliver a lethal dose of radiation to the tumor cells.
Epidural steroid injection for sciatica and spinal stenosis is of unclear effect. [1] The evidence to support use in the cervical spine is not very good. [3] When medical imaging is not used to determine the proper spot for injection, ESI benefits appear to be of short-term benefit when used in sciatica. [4]
A technique called Intensity Modulated Radiation Therapy may be used to adjust the radiation beam to conform with the shape of the tumor, allowing higher doses to be given to the prostate and seminal vesicles with less damage to the bladder and rectum. External beam radiation therapy is generally given over several weeks, with daily visits to a ...
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin. [1]Brachytherapy can also be used in the treatment of tumours of the brain, eye, head and neck region (lip, floor of mouth, tongue, nasopharynx and oropharynx), [10] respiratory tract (trachea and bronchi), digestive tract (oesophagus, gall ...
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
