Usage

Function of Atracurium Besylate

Atracurium besylate is a skeletal muscle relaxant for general anesthesia, suitable for the treatment of muscle relaxation for endotracheal intubation and for muscle relaxation required for thoracic and abdominal surgery. Like most neuromuscular blocking agents, it can Causes the release of histamine, skin flushing, transient hypotension, and occasionally bronchospasm. Caution should be used in patients with myasthenia gravis, neuromuscular disease, and severe electrolyte disturbances, as it potentiates the effects of other non-depolarizing agents. People with severe cardiovascular disease are more sensitive to the transient hypotensive reaction of this product, so it is recommended to give slow intravenous injection in divided doses.
