Intravenous Induction Agents & Commonly Used Drugs
IV induction agents rapidly induce unconsciousness. Propofol is first-line for stable patients (antiemetic, rapid recovery). Etomidate is hemodynamically neutral for RSI in shock but causes adrenal suppression. Ketamine supports BP in hypovolemia/asthma but may increase ICP. Thiopental is now largely replaced due to cardiovascular risks.
