What medication would be ineffective when attempting to accommodate a cough reflex during bronchoscopy?

Anectine, known generically as succinylcholine, is a neuromuscular blocker that induces muscle paralysis. It works by binding to nicotinic acetylcholine receptors at the neuromuscular junction, preventing muscle contractions. During a procedure like bronchoscopy, which involves visualizing and performing interventions in the airways, it's essential that the cough reflex remains intact to protect the airway from aspiration and other complications.

By using a neuromuscular blocker like Anectine, the cough reflex would be suppressed, making it ineffective for accommodating the cough reflex during bronchoscopy. This is critical because maintaining an active cough reflex can help clear secretions and prevent complications during the procedure. In contrast, local anesthetics like lidocaine and aprocaine would numb the mucosal surfaces without affecting the patient's ability to cough, preserving the protective airway reflexes needed during bronchoscopy.
