Insights

Off-pump coronary artery bypass grafting (OPCAB) is safe for hemodialysis (HD)-dependent patients, showing similar perioperative outcomes and improved long-term survival rates compared to non-HD patients.

Area of Science:

  • Cardiovascular Surgery
  • Nephrology
  • Oncology

Background:

  • Coronary artery disease is prevalent in patients requiring hemodialysis.
  • Surgical risk stratification in hemodialysis patients undergoing cardiac surgery is crucial.

Purpose of the Study:

  • To evaluate the safety and efficacy of off-pump coronary artery bypass grafting (OPCAB) in hemodialysis-dependent patients.
  • To compare perioperative and long-term outcomes of OPCAB between hemodialysis (HD) and non-HD patient groups.

Main Methods:

  • Retrospective analysis of isolated OPCAB procedures from 2000 to 2006.
  • Comparison of perioperative data between HD (n=39) and non-HD (n=60) groups.
  • Examination of long-term survival in the HD group.

Main Results:

  • Complete all-arterial revascularization was less frequent in the HD group.
  • Mortality, operative time, ICU stay, hospital stay, and need for transfusions were similar between groups.
  • Actuarial 1- and 5-year survival rates in the HD group were 80% and 70%, respectively.

Conclusions:

  • Off-pump coronary artery bypass grafting (OPCAB) is a safe procedure for hemodialysis-dependent patients.
  • OPCAB demonstrates improved long-term survival in patients requiring hemodialysis.

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...

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...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...

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...

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
