Insights

Coronary artery bypass (CAB) in dialysis patients shows acceptable outcomes. This study found hospital mortality was 5.3% and 5-year survival was 72%, suggesting CAB is a viable option for these patients.

Area of Science:

  • Cardiovascular Surgery
  • Nephrology
  • Oncology

Background:

  • Dialysis patients often have complex cardiovascular disease.
  • Coronary artery bypass surgery (CAB) in this population presents unique challenges.
  • Evaluating operative outcomes is crucial for patient management.

Purpose of the Study:

  • To assess the surgical outcomes of dialysis patients undergoing coronary artery bypass (CAB).
  • To determine the safety and efficacy of CAB in patients with end-stage renal disease.
  • To analyze survival rates and perioperative results in this high-risk group.

Main Methods:

  • Retrospective analysis of 38 dialysis patients who underwent CAB over 6 years.
  • Data collected on patient demographics, operation type, and perioperative management.
  • Assessment of hospital mortality and long-term actuarial survival rates.

Main Results:

  • Hospital mortality was 5.3% among the 38 patients.
  • Actuarial survival rates at 1, 3, and 5 years were 88%, 80%, and 72%, respectively.
  • Internal thoracic artery was used in all cases; 2.8 bypass grafts were average.

Conclusions:

  • Coronary artery bypass can be performed with acceptable mortality and morbidity in dialysis patients.
  • Improvements in perioperative care enhance outcomes.
  • Complete revascularization without cardiopulmonary bypass is ideal but conventional CAB also yields acceptable results.

Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

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...

Hemodialysis II: Procedure and Complications

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,...

Hemodialysis III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this measurement...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...
