Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

395
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacodynamics in Geriatric Patients: Effects of Age

367
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

861
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

General Anesthesia: Overview01:24

General Anesthesia: Overview

1.1K
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

382
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Stages of General Anesthesia01:22

Stages of General Anesthesia

2.6K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Area of Science:

  • Geriatric Medicine
  • Anesthesiology
  • Surgical Care

Context:

  • Elderly surgical patients present unique challenges due to aging variability and chronic conditions.
  • Increased sensitivity to anesthetic agents necessitates specialized anesthetic management.
  • Heterogeneity of the elderly population requires individualized perioperative strategies.

Purpose:

  • To review specific concerns in the perioperative management of elderly surgical patients.
  • To emphasize the importance of tailored anesthetic and surgical care for older adults.
  • To guide clinicians in optimizing outcomes for geriatric surgical cases.

Summary:

  • Elderly patients are a diverse group with varying degrees of aging and chronic illness.
  • Anesthesia administration is complex due to heightened sensitivity to anesthetic drugs.
  • Preoperative evaluation and intraoperative care must account for potential organ dysfunction.

Impact:

  • Improved perioperative outcomes for elderly surgical patients.
  • Enhanced understanding of anesthetic risks and management in geriatric surgery.
  • Development of evidence-based guidelines for the care of aging surgical populations.
