Final answer:
D-tubocurarine is contraindicated for the management of acute Malignant Hyperthermia being treated with dantrolene. Pralidoxime chloride is used to treat nerve agent poisoning.
Step-by-step explanation:
The medication contraindicated for the management of acute Malignant Hyperthermia being treated with dantrolene is d-tubocurarine. D-tubocurarine is a competitive antagonist of acetylcholine that blocks its action at the neuromuscular junction, resulting in muscle relaxation and paralysis. It is important to note that dantrolene is the primary medication used to treat Malignant Hyperthermia, and d-tubocurarine is contraindicated.
Another medication mentioned in the reference is pralidoxime chloride, which is used to treat nerve agent poisoning. It reactivates the poisoned enzyme acetylcholinesterase and works more effectively on nicotinic receptors, while atropine is more effective on muscarinic receptors.
