Careful consideration of nitrogen load, especially in patients with kidney disease.
Atkins Diet:
Not suitable for individuals with kidney disease due to high protein content.
Can overload the kidneys, making it challenging for them to filter effectively.
Patients with kidney issues may struggle with dietary restrictions.
Fluid restrictions are critical in managing kidney disease:
Replacement of electrolytes based on lab values is essential.
Potassium levels are often elevated; other electrolytes may vary.
Dialysis Overview
Definition and Purpose of Dialysis:
Dialysis serves as a substitute for normal kidney function by filtering blood and eliminating waste, excess fluid, and unwanted substances.
Types of Dialysis:
Hemodialysis: Uses a machine to filter blood outside the body.
Peritoneal Dialysis: Utilizes the peritoneum in the abdomen as a filter.
Hemodialysis
Hemodialysis Process:
Blood is pulled through a fistula into a dialysis machine where it is filtered.
Dialysate (a hypertonic solution) is used to draw out impurities and excess water.
Risks and Complications:
Hypovolemia from pulling off too much fluid can cause symptoms like low blood pressure.
Disequilibrium Syndrome: A condition that occurs due to rapid fluid removal; can induce tachycardia and other symptoms.
Vascular Access:
AV Fistula: A connection created surgically between an artery and vein to facilitate access for dialysis.
Can take time to heal and is monitored for patency using a bruit (auscultation) and thrill (palpation).
Care Considerations:
Ensure distal blood flow is intact to prevent complications following fistula creation.
Typically, patients undergo dialysis three times a week, experiencing fluctuating energy and well-being between sessions.
Peritoneal Dialysis
Peritoneal Dialysis Process:
Dialysate is infused into the peritoneal cavity, where it dwells to allow waste and excess fluid to cross the membrane and be drained afterward.
Risks and Complications:
Prone to infections like peritonitis, especially with contaminated access sites.
Requires careful management of input and output of dialysate to prevent fluid trapping.
Additional Considerations:
Cleaning protocols must be stringent to avoid infections.
Dialysate warming may be utilized to enhance absorption and effluent quality.
Key Assessment and Monitoring
Assessment of Fistula Patency:
Use auscultation to listen for a bruit and palpate for a thrill.
Monitor perfusion distal to the fistula to ensure adequate blood supply to the hand.
Assessment of Patients Undergoing Dialysis:
Take baseline vital signs and monitor fluctuations in blood pressure and heart rate during treatments.
Patient Education:
Discuss dietary restrictions, importance of compliance with treatment, and awareness of complications related to dialysis.
Continuous Renal Replacement Therapy (CRRT)
Description:
A continuous form of dialysis suitable for critically ill patients with unstable conditions.
Employs a machine that continuously removes blood for filtration, managing a slow but steady fluid removal rate.
Important Monitoring:
Vigilance required for blood clots within the filter, as they can lead to significant blood loss if not addressed promptly.
Renal Surgery and Procedures
Overview of Renal Surgical Procedures:
Mention of TURP (Transurethral Resection of Prostate) as a surgical option for BPH (Benign Prostatic Hyperplasia).
Post-Operative Care:
Monitoring for blood loss or infection following surgical interventions.
Continuous Bladder Irrigation (CBI) to manage post-surgical bleeding in the bladder; requires a triple lumen catheter for infusion and drainage.
Diagnostics Related to Renal Function
Important diagnostic tests:
KUB (Kidney, Ureter, Bladder) - a plain abdominal X-ray to check for stones and kidney position.
Intravenous Pyelogram (IVP) - assesses kidney function and structure using contrast dye; requires assessment of allergies and renal function prior to administration.
Key Education Points for Tests:
Patient may experience discomfort and a sensation of urgency post-IVP dye injection but may not be allergic.
