Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

467
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

678
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

52
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Hemodialysis II: Procedure and Complications

199
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Venous Thrombosis III: Interprofessional Care

64
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Area of Science:

  • Nephrology Nursing
  • Patient Safety in Hemodialysis

Background:

  • Venous needle dislodgement (VND) and access-bloodline separation are serious complications during hemodialysis.
  • The American Nephrology Nurses Association (ANNA) previously addressed VND in 2012.

Purpose of the Study:

  • To update information and resources on VND and access-bloodline dislodgement.
  • To develop new resources and practice recommendations for preventing these complications.

Main Methods:

  • Conducted a comprehensive literature review.
  • Solicited information and experiences from ANNA members.
  • Tested various taping techniques for securement.

Main Results:

  • The literature review identified current evidence on VND and related issues.
  • ANNA member input provided practical insights and challenges.
  • Taping technique testing offered data on effectiveness.

Conclusions:

  • Updated resources and recommendations are available for managing VND and access-bloodline dislodgement.
  • These updates aim to enhance patient safety in hemodialysis settings.
  • Continuous evaluation and resource development are crucial for nephrology nursing practice.
