Anaesthesia · Induction agents: ketamine

Sample item

Which induction agent is especially useful when preservation of spontaneous breathing and bronchodilation are desirable, while recognizing it may increase secretions?

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

The answer and the reasoning

D. Ketamine

Ketamine produces dissociative anesthesia with analgesia and bronchodilation, and it tends to preserve airway reflexes and sympathetic tone better than many other induction agents. Emergence reactions and increased secretions are relevant considerations.

Option by option

  • A. Thiopental

    Thiopental has no analgesic effect and can cause cardiovascular and respiratory depression.

  • B. Propofol

    Propofol commonly causes hypotension and has no analgesia.

  • C. Midazolam

    Midazolam is a sedative-amnesic, not a primary bronchodilating induction agent.

  • D. Ketamine (correct)

    Correct. Ketamine's bronchodilatory and sympathetic properties are useful in selected patients.
