Atracurium has many effects, the main ones are as follows: First, the drug is a neuromuscular blocking agent, a medium-acting, non-depolarizing skeletal muscle relaxant that binds to cholinergic receptors on the motor junction plate to antagonize the action of acetylcholine, resulting in a competitive neuromuscular conduction blocking effect. Second, the drug can treat occupational skeletal muscle disorders, used in surgical operations, other operations and intensive care treatment, as an adjunct to general anesthesia acts as a sedative, can relax the skeletal muscle, so that tracheal intubation and mechanical ventilation can be easily carried out. In summary, atracurium has a variety of effects, should be used under the close supervision of anesthesiologists, and should be equipped with equipment for tracheal intubation, artificial respiration, patients with severe cardiovascular disease should be injected slowly in small doses, and must comply with the rules of drug administration.
