conduction anesthesia definition: block anesthesia; regional anesthesia in which local anesthetic solution is injected about nerves to inhibit nerve transmission; includes spinal, epidural, nerve block, and field block anesthesia, but not local or topical anesthesia.
Anesthetics, Local definition: Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
local anesthetic definition: drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations; they act on any part of the nervous system and on every type of nerve fiber; their action is completely reversible.
Atrioventricular Block definition: Impaired impulse conduction from HEART ATRIA to HEART VENTRICLES. AV block can mean delayed or completely blocked impulse conduction.
Atrioventricular Block definition: A delay or failure in the conduction of a cardiac impulse from the atria to the ventricles at the level of the atrioventricular node.
Bone Conduction definition: Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.
Heart Conduction System definition: An impulse-conducting system composed of modified cardiac muscle and having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.
heart conduction system definition: impulse conducting system composed of modified cardiac muscle and having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.
Conducting system of heart definition: Conducting tissue of heart which consists of specialized cardiac myocyte in the myocardium.
Neural Conduction definition: The propagation of the NERVE IMPULSE along the nerve away from the site of an excitation stimulus.
neural conduction definition: movement of a nerve impulse along a single nerve.
CATHETER, CONDUCTION, ANESTHETIC definition: An anesthesia conduction catheter is a flexible tubular device used to inject local anesthetics into a patient and to provide continuous regional anesthesia.
Aphasia, Conduction definition: A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication. (From Adams et al., Principles of Neurology, 6th ed, p482; Brain & Bannister, Clinical Neurology, 7th ed, p142; Kandel et al., Principles of Neural Science, 3d ed, p848)
Heart Conduction Disorder definition: A disorder affecting the conduction system that sends electrical signals in the myocardium.
Conduction definition: The transmission or conveying of something through a medium or passage, especially the transmission of heat or electricity or sound.
FILTER, CONDUCTION, ANESTHETIC definition: An anesthesia conduction filter is a microporous filter used while administering to a patient injections of local anesthetics to minimize particulate (foreign material) contamination of the injected fluid.
HEARING-AID, AIR-CONDUCTION definition: A hearing aid is wearable sound-amplifying device that is intended to compensate for impaired hearing. This generic type of device includes the air-conduction hearing aid and the bone-conduction hearing aid, but excludes the group hearing aid or group auditory trainer (Sec. 874.3320), master hearing aid (Sec. 874.3330), and tinnitus masker (Sec. 874.3400).
HEARING-AID, BONE-CONDUCTION definition: A hearing aid is wearable sound-amplifying device that is intended to compensate for impaired hearing. This generic type of device includes the air-conduction hearing aid and the bone-conduction hearing aid, but excludes the group hearing aid or group auditory trainer (Sec. 874.3320), master hearing aid (Sec. 874.3330), and tinnitus masker (Sec. 874.3400).
Bone Conduction Assessment definition: A test of the transmission of sound to the inner ear through the bones of the skull. This testing can measure functionality of the inner ear independent of the functionality of the outer and middle ears.
