Anaesthetic drugs in the elderly

Area of Science:

• Geriatric Anesthesia
• Pharmacology
• Surgical Patient Care

Background:

• Surgical outcomes in the elderly are influenced by anesthesiologist expertise.
• Age-related physiological changes significantly impact drug kinetics and dynamics.
• The elderly population's heterogeneity leads to unpredictable drug responses, limiting practice guidelines.

Purpose of the Study:

• To review important physiological and pharmacokinetic changes with aging relevant to anesthesia.
• To discuss specific anesthetic drugs used in the United Kingdom.
• To focus on drugs for induction, maintenance, and neuromuscular blockade.

Main Methods:

• Review of current literature on anesthetic agents and aging.
• Discussion of physiological and pharmacokinetic alterations in elderly patients.
• Focus on intravenous drugs, anesthetic vapors, and neuromuscular blocking agents.

Main Results:

• Significant age-related changes in physiology and pharmacokinetics affect anesthetic drug action.
• Key anesthetic drugs, including vapors and intravenous agents, are discussed in the context of aging.
• Neuromuscular blocking agents are covered, highlighting age-specific considerations.

Conclusions:

• Understanding age-related changes is crucial for effective anesthetic management in the elderly.
• Specific anesthetic drugs and their altered profiles in older patients are essential knowledge for anesthesiologists.
• This review provides a focused overview of major anesthetic drug classes for UK practice in elderly patients.
