Insights

Seizures during hemodialysis are uncommon in end-stage renal disease patients. While some may experience seizures during dialysis, they typically do not become chronic, suggesting occasional rather than persistent neurological events.

Area of Science:

  • Nephrology
  • Neurology

Background:

  • End-stage renal disease (ESRD) patients undergoing hemodialysis are susceptible to complications.
  • Hemodialysis-associated seizures represent a significant, though infrequent, complication in this population.

Purpose of the Study:

  • To investigate the occurrence and characteristics of seizures in patients with ESRD undergoing dialysis.
  • To determine if seizures in ESRD patients on dialysis tend to become chronic.

Main Methods:

  • Retrospective review of medical histories of 189 patients undergoing dialysis.
  • Selection of five patients with a history of seizures for detailed analysis.
  • Classification of seizure types and timing relative to dialysis sessions.

Main Results:

  • Five ESRD patients experienced seizures during the study period.
  • Seizure types included generalized tonic-clonic, partial with secondary generalization, and unclassified.
  • Three patients had seizures exclusively during dialysis; one experienced convulsive status epilepticus.
  • Two patients had a prior history of seizures before commencing dialysis.

Conclusions:

  • Seizures in patients with renal failure undergoing hemodialysis are generally occasional events.
  • The data suggests that these seizures do not typically develop into a chronic condition.
  • Further research may clarify the specific mechanisms and risk factors for hemodialysis-associated seizures.

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,...

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 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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

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...
