Topical, on the surface of the body. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- It`s possible to deduce that, that said, there are times that the use of an anesthetic cream is impractical. For example, if the chemotherapy is being delivered by continuous infusion (eg, >24 hours, >96 hours, etc), using a topical anesthetic would require the therapy to stop for the period of time between removing the old non-coring needle and the time needed for the numbing agent to take effect, which is sometimes 30 to 45 minutes. Continuous infusion is the administration of a fluid into a blood vessel, usually over a prolonged period of time. Chemotherapy, treatment with drugs that kill cancer cells. Infusion is a method of putting fluids, including drugs, into the bloodstream. Also called intravenous infusion.
- It might seem to be apparant that, options for anesthetics, such as topical lidocaine 2.5% and prilocaine 2.5% cream (EMLA cream), should be considered. As a home care nurse, if no anesthetic cream is available, I have successfully used ice to numb the area for a few minutes prior to skin preparation and port access. Port is an implanted device through which blood may be withdrawn and drugs may be infused without repeated needle sticks. Also called port-a-cath. ICE is an abbreviation for a chemotherapy combination that is used to treat non-Hodgkin and Hodgkin lymphomas that have come back and do not respond to other treatments. It includes the drugs ifosfamide, carboplatin, and etoposide phosphate. Also called ICE regimen. Nurse is a health professional trained to care for people who are ill or disabled. Lidocaine is a substance used to relieve pain by blocking signals at the nerve endings in skin. It can also be given intravenously to stop heart arrhythmias. It is a type of local anesthetic and antiarrhythmic.
- It really is clear that, several types of anesthetics are available including topical, injectable, and nonpharmacological methods.
