Prolonged intermittent renal replacement therapy in the intensive care unit
Summary
Prolonged intermittent renal replacement therapy (PIRRT) offers an alternative to continuous renal replacement therapy (CRRT) for acute renal failure in critically ill patients. PIRRT provides benefits of CRRT with reduced technical demands and cost implications.
Area of Science:
- Nephrology
- Critical Care Medicine
- Intensive Care Unit (ICU) Management
Background:
- Standard intermittent hemodialysis (IHD) has limitations in treating acute renal failure (ARF) in critically ill patients, including hemodynamic instability and suboptimal solute control.
- Continuous renal replacement therapy (CRRT) offers advantages over IHD but is technically demanding, requires 24-hour supervision, and may necessitate continuous anticoagulation.
- CRRT implementation can increase costs and impact resource availability in intensive care units.
Purpose of the Study:
- To review the application of prolonged intermittent renal replacement therapy (PIRRT) in intensive care patients.
- To explore PIRRT as a potentially cost-effective and less demanding alternative to CRRT for ARF management.
Main Methods:
- Review of articles and abstracts detailing the use of renal replacement therapy.
- Focus on techniques that prolong intermittent therapy duration (PIRRT) for ARF in the ICU.
- PIRRT principles include using modified dialysis machines, diffusion/convection, decreased solute removal intensity, extended treatment (8-12 hours), and online dialysate generation.
Main Results:
- PIRRT aims to mitigate the shortcomings of standard IHD while avoiding the intensive resource requirements of CRRT.
- PIRRT utilizes modified or standard dialysis machines for extended intermittent treatments, offering a balance between efficacy and resource utilization.
- Emerging information suggests PIRRT is being adopted in some Australian ICUs.
Conclusions:
- Prolonged intermittent renal replacement therapy (PIRRT) is an evolving treatment modality for acute renal failure in intensive care.
- PIRRT presents a viable option that combines benefits of intermittent and continuous therapies, addressing limitations of both.
- Critical care professionals should become familiar with the principles and practical application of PIRRT in patient care.

01:30Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
01:26Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

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...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
01:22Acute Kidney Injury I: Introduction
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
