Which action should be taken with acetylcholinesterase inhibitors prior to anesthesia?

• A. Continue acetylcholinesterase inhibitors as prescribed.
• B. Increase the dose of acetylcholinesterase inhibitors.
• C. Switch to another class of medication.
• D. Hold acetylcholinesterase inhibitors before anesthesia.

Answer: (D)

Holding acetylcholinesterase inhibitors before anesthesia is advised because these drugs raise acetylcholine levels at the neuromuscular junction and at parasympathetic sites. During anesthesia, the combination with anesthetic agents and neuromuscular blockers can make blockades unpredictable and complicate reversal, increasing risks of prolonged weakness, respiratory problems, bradycardia, and hemodynamic instability. Stopping the medication the day of surgery helps achieve more predictable neuromuscular blockade and smoother recovery. Continuing or increasing the dose would heighten cholinergic effects and complicate intraoperative management, while switching classes isn’t the standard approach.
