KROK 1 2007 – Question 168 · KROK (Medicine) · Pharmacology
A patient with fracture of his lower jaw was admitted to the maxillofacial department. It was decided to fix his bones surgically under anaesthetic. After intravenous introduction of muscle relaxant there arose short fibrillar contractions of the patient’s facial muscles. What muscle relaxant was applied?
- A. Pipecuronium bromide
- B. Tubocurarin chloride
- C. Diazepam
- D. Melictine
- E. Dithylinum
Hint
Brief twitching before paralysis suggests the drug first stimulates the motor end-plate before blocking it; ask which relaxant mechanism produces that sequence.
