Anaesthesia · Neuromuscular blockade: rocuronium reversal

Sample item

At the end of surgery, which drug can rapidly reverse a rocuronium-induced neuromuscular block by encapsulating the blocker?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Sugammadex

Sugammadex selectively binds steroidal neuromuscular blockers such as rocuronium, reducing free drug concentration and reversing paralysis. Its use should be guided by block depth and local practice.

Option by option

  • A. Dantrolene

    Dantrolene treats malignant hyperthermia.

  • B. Sugammadex (correct)

    Correct. Sugammadex encapsulates rocuronium molecules.

  • C. Naloxone

    Naloxone reverses opioid effects.

  • D. Atropine

    Atropine is an antimuscarinic used for bradycardia or with neostigmine in some contexts.
