The effect of succinylcholine on denervated skeletal muscle. 1981

J R Doyle, and J Semenza, and B Gilling

Succinylcholine, commonly used in anesthesia, paralyzes normal skeletal muscles by blocking transmission at the myoneural junction, but in denervated muscle, it produces sustained muscle contractions lasting several minutes. This denervation hypersensitivity, believed to be due to the progressive enlargement of the receptor area, begins within 2 to 3 weeks and may last for months. Three patients with denervation hypersensitivity were studied: one with isolated denervation of the flexor pollicis longus and two with combined median and ulnar nerve palsy. Within 1 to 2 minutes after administration of succinylcholine, sustained contraction of the denervated muscles occurred and lasted 4 to 5 minutes. Succinylcholine, due to its ability to produce sustained muscle contraction in denervated muscles, may be a useful diagnostic aid in distinguishing loss of function due to nerve injury from tendon disruption.

UI MeSH Term Description Entries
D008297 Male Males
D008475 Median Nerve A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand. Median Nerves,Nerve, Median,Nerves, Median
D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments. Inotropism,Muscular Contraction,Contraction, Muscle,Contraction, Muscular,Contractions, Muscle,Contractions, Muscular,Inotropisms,Muscle Contractions,Muscular Contractions
D009132 Muscles Contractile tissue that produces movement in animals. Muscle Tissue,Muscle,Muscle Tissues,Tissue, Muscle,Tissues, Muscle
D009435 Synaptic Transmission The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.

D010243 Paralysis A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function.
