True or False: Succinylcholine can cause transient muscle twitching before achieving its depolarizing effect.

True or False: Succinylcholine can cause transient muscle twitching before achieving its depolarizing effect.

• A. True
• B. False
• C. Only in certain patients
• D. True, but only at high doses

Answer: (A)

Succinylcholine is a depolarizing neuromuscular blocking agent used to induce muscle relaxation during surgical procedures and intubation. When succinylcholine is administered, it works by mimicking acetylcholine, binding to the nicotinic receptors at the neuromuscular junction, which leads to an initial depolarization of the motor end plate. This depolarization phase often manifests as transient muscle twitching or fasciculations. The twitching occurs because succinylcholine causes persistent stimulation of the muscle fibers, leading to involuntary contractions prior to the sustained paralysis that follows. This initial fasciculation is a notable characteristic of succinylcholine use and reflects its mechanism of action. Therefore, stating that succinylcholine can cause transient muscle twitching before achieving its depolarizing effect is accurate. This understanding is crucial for anticipating the immediate effects of the drug upon administration in clinical settings.
