Insights

The COVID-19 infection rate in hemodialysis patients was high, with a 30.2% cumulative incidence. Strict biosafety measures are crucial for preventing outbreaks in dialysis units.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Epidemiology

Background:

  • Controlling SARS-CoV-2 in hemodialysis (HD) units presents significant challenges.
  • Patients with chronic kidney disease (CKD) on HD are a vulnerable population for severe COVID-19 outcomes.

Purpose of the Study:

  • To characterize the clinical presentation and outcomes of COVID-19 in CKD patients undergoing HD.
  • To determine the incidence, prevalence, and case-fatality rates of SARS-CoV-2 infection in a Colombian HD unit.

Main Methods:

  • Prospective observational study conducted from March 2020 to January 2021.
  • Screening included RT-PCR and anti-SARS-CoV-2 IgG/IgM antibody testing for all patients and staff.
  • Epidemiological metrics such as incidence, prevalence, and case-fatality rates were calculated.

Main Results:

  • Identified 55 COVID-19 cases in patients and 9 in health personnel.
  • The cumulative incidence of infection was 30.2%, with a population seroprevalence of 24.9%.
  • The case-fatality rate among infected patients was 9.1%; common symptoms included fever, cough, and myalgia.

Conclusions:

  • The study revealed a high incidence of SARS-CoV-2 infection within the hemodialysis unit.
  • Emphasizes the critical need for stringent biosafety protocols to mitigate outbreaks in HD settings.

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...

Dialysis01:27

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...

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 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...

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
