Abstract:
Electric sympathetic block is the procedure whereby sympathetic nerve fibers are blocked by application of controlled electrical impulses via electrodes placed on the skin. Methods of measuring the extent of sympathetic blockade and a clinical study using bipolar middle frequency currents to achieve electric sympathetic block are presented. Fifteen of 20 (75%) patients who underwent a 1-week series of electric sympathetic blocks reported at least 75% subjective relief from sympathetically mediated pain after completion of the series.

01:28Drugs Acting on Autonomic Ganglia: Blockers
Ganglionic blockers inhibit autonomic activity by blocking nicotinic receptors in the autonomic ganglia, suppressing impulse transmission. These blockers lack selectivity between sympathetic and parasympathetic ganglia and are ineffective as neuromuscular junction antagonists. They can be categorized into two groups:
01:28Depolarizing Blockers: Mechanism of Action
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...
