What adjustments are recommended for geriatric or pediatric patients undergoing anesthesia?

• A. Higher starting doses, faster titration, longer monitoring.
• B. Lower starting doses, slower titration, longer monitoring; consider organ function and comorbidity.
• C. No changes in dosing or monitoring.
• D. Avoid considering organ function.

Answer: (B)

Dosing and monitoring must be tailored for age because how drugs behave changes with age. In older patients, organ function often declines—renal clearance and hepatic metabolism slow down—altering drug clearance and prolonging effects. Body composition shifts too, with more fat and less lean mass, which can change how drugs distribute and linger in the body, making them more potent or longer-lasting. There’s also increased sensitivity to central nervous system depressants, and a higher risk of hemodynamic instability and delirium. In pediatric patients, immature organ systems and developing physiology mean drugs can have unpredictable onset and duration. Liver enzymes, kidney function, and protein binding may not be fully mature, and distribution can differ due to higher total body water or varying fat content depending on age. All of this makes careful, incremental dosing essential.

That’s why the recommended approach is to start with lower starting doses, titrate slowly to achieve the desired effect, and monitor the patient longer to detect delayed or cumulative responses. It’s also important to factor in organ function and any existing illnesses that could affect drug handling. Higher starting doses or rapid titration can lead to oversedation or respiratory or cardiovascular complications, and ignoring age-related differences is not safe.
