Summary
Critically ill patients with acute kidney injury (AKI) require specialized nutrition. This review explores nutritional support strategies during continuous renal replacement therapy (CRRT) for better patient outcomes.
Area of Science:
- Critical care medicine
- Nephrology
- Clinical nutrition
Background:
- Nutrition is crucial for critically ill patients, impacting recovery and treatment.
- Acute kidney injury (AKI) presents significant metabolic and nutritional challenges in critical care.
- Renal replacement therapy (RRT), including continuous renal replacement therapy (CRRT), complicates nutritional management due to substrate shifts.
Purpose of the Study:
- To review the complex interactions between nutritional support and CRRT in critically ill patients.
- To highlight the scarcity of evidence and guidelines for nutrition during CRRT.
- To present key considerations for nutritional management in this patient population.
Main Methods:
- Literature review focusing on nutritional support in critically ill patients undergoing CRRT.
- Analysis of the impact of RRT and extracorporeal circuits on metabolic and nutritional status.
- Synthesis of expert opinions and available evidence.
Main Results:
- Nutritional support is fundamental but challenging in critically ill patients with AKI on CRRT.
- CRRT modalities and extracorporeal circuits significantly alter nutrient balance, complicating energy requirement assessments.
- Evidence and clinical guidelines for nutritional support during CRRT are limited, relying heavily on expert opinion.
Conclusions:
- Optimizing nutritional support for critically ill patients on CRRT requires careful consideration of metabolic changes.
- Further research is needed to establish evidence-based guidelines for nutrition during CRRT.
- This review provides milestones to guide nutritional management in this complex patient group.

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...

25
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...

01:25Chronic Kidney Disease I: Introduction
36
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage kidney disease (ESKD). At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate...

25
Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...
