A 55-year-old male with chronic obstructive pulmonary disease (COPD) and hypertension is scheduled for elective hernia repair under general anesthesia. Which of the following induction agents is MOST appropriate for this patient?

Explanation

## Induction Agent Selection in High-Risk Patients **Etomidate** is the most appropriate choice for this patient with COPD and hypertension. ### Why Etomidate? - **Minimal respiratory depression**: Maintains spontaneous ventilation and airway reflexes better than other agents - **Cardiovascular stability**: Maintains blood pressure and heart rate, crucial in a hypertensive patient - **Rapid onset**: Allows quick airway control if needed - **Preserved airway reflexes**: Important in COPD patients at risk of aspiration ### Why Other Agents Are Suboptimal: | Agent | Drawback in This Patient | |-------|-------------------------| | **Propofol** | Severe cardiovascular depression (↓BP, ↓HR), respiratory depression; contraindicated in COPD | | **Thiopental** | Profound respiratory depression, cardiovascular depression; outdated for routine use | | **Methohexital** | Similar to thiopental; respiratory and CV depression; rarely used now | **Key Point:** In patients with COPD and hypertension, etomidate's unique combination of hemodynamic stability and minimal respiratory depression makes it the gold standard induction agent, despite the caveat of adrenal suppression with single doses (though clinically insignificant). **High-Yield Fact:** Etomidate maintains cerebral perfusion pressure and is also preferred in critically ill and septic patients for the same reason.
