Disorders of Hemostasis01:24

Disorders of Hemostasis

2.7K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Venous Thrombosis IV: Nursing Management

379
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Pharmacodynamics in Geriatric Patients: Effects of Age

317
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 Distribution

340
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

316
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Drug Dosing: Geriatric Patients

347
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...

  • Hematology
  • Internal Medicine

Background:

  • Advancing age alters the hemostatic balance, increasing thrombosis risk.
  • Age-related physiological changes and comorbidities predispose the elderly to bleeding disorders.
  • Common medications like anticoagulants and NSAIDs exacerbate bleeding risks in older adults.

Purpose of the Study:

  • To discuss the specific challenges of acquired bleeding in the elderly.
  • To highlight the importance of balancing thrombotic and bleeding risks in this population.
  • To review rare acquired bleeding disorders predominantly affecting the elderly.

Main Methods:

  • Review of physiological changes affecting hemostasis in aging.
  • Analysis of medication-induced bleeding risks in the elderly.
  • Discussion of acquired bleeding disorders such as acquired hemophilia and acquired von Willebrand syndrome.

Main Results:

  • Aging promotes a prothrombotic state but also increases bleeding susceptibility.
  • Therapeutic anticoagulation and antiplatelet use in the elderly carry significant bleeding risks.
