Which set is described as Common induction drugs?

• A. Oxygen, Lidocaine, Propofol, Fentanyl, Succinylcholine, and Rocuronium
• B. Propofol, Etomidate, Ketamine, Lidocaine
• C. Sevoflurane and Isoflurane
• D. Morphine and Midazolam

Answer: (A)

Induction drugs aim to rapidly render the patient unconscious, provide analgesia, and achieve muscle relaxation to facilitate airway management. A common induction regimen includes preoxygenation with oxygen, an IV induction agent to quickly depress consciousness, an opioid to blunt the stress response and provide analgesia, and a neuromuscular blocker to enable intubation. Lidocaine is often used as an adjunct to blunt airway reflexes. The set that includes oxygen for preoxygenation, lidocaine as an adjunct, propofol as the induction agent, fentanyl as the analgesic, and either succinylcholine or rocuronium as the muscle relaxant aligns with typical practice for rapid sequence and regular induction. The other options omit one or more essential components (such as the neuromuscular blocker or the combination of an induction agent with adjuncts and a muscle relaxant), making them less representative of common induction regimens.
