Renal Support Flashcards
What is ESRD (end stage renal disease)
End stage renal disease/failure (ESRD) – when death is likely without renal replacement therapy i.e eGFR < 15ml/min.
What are some of the symptoms of ESRD?
Symptoms of ESRD – overwhelmingly tired, physically and mentally incapacitated, feelings of guilt and ineptitude at needing rest, difficulty sleeping and difficulty concentrating.
Signs of volume overload, nausea and vomiting, reduced appetite (especially protein), restless legs and cramps, pruritus (severe itching), sexual dysfunction and reduced fertility and increased infections (reduced cellular and humeral immunity).
How does the volume of urine produced in a day change with ESRD and why?
Normally we can pee in the range of 0.5l to 30l in a day. CKD they have a much reduced GFR but still have the same amount of solute that they need to excrete however due to the low filtration rate it becomes increasingly hard to get rid of liquid from the body so this dramatically limits the amount they can pee out to between 1-2L.
What effect does acidosis have on bone disease and muscles?
Acidosis worsens bone disease and can cause muscle wasting.
How do we deal with the acid-base and electrolyte disturbances in ESRD patients?
Generally asymptomatic, can require additional medication such as sodium bicarbonate (makes patients windy) and alteration of medication such as stopping ACE inhibitors.
What effects does the build up of waste products cause?
Contributes to uraemic symptoms, reduced appetite, nausea, vomiting and pruritus.
What is haemodialysis?
Allowing a machine to filter someone’s blood for them, requires a fistula being put into someone’s arm. 4 hours 3 times a week.
What are the advantages and disadvantages of haemodilaysis?
Advantages – less responsibility, days off. disadvantages – travel time/waiting, tied to dialysis times and big restriction on fluid food intake. On average they are on 19 pills
What contraindications are there for haemodialysis?
Failed vascular access, heart failure, coagulopathy
What complications can occur with haemodilaysis?
Lines – infection, thrombosis and venous stenosis, AVFthombosis, bleeding, access failure, steal syndrome, CVS instability, feel chronically unwell and accumulate morbidity (CVS bone etc.)
What is Home/Nocturnal HD?
Home HD/Nocturnal HD are options for haemodialysis. Patients often feel much better as they get more hours and can watch TV or something whilst doing it. Must have carer with you. Often need fewer medications.
What is peritoneum dialysis?
Uses peritoneum as a filter and fill with dialysis liquid then remove liquid later once full of waste products.
What are the advantages and disadvantages of peritoneum dialysis?
Advantages: self-sufficient, generally less fluid/food restriction, fairly easy to travel with CAPD (continuous ambulatory peritoneal dialysis) and renal function may be better preserved initially. Disadvantages – frequent daily exchanges or overnight and responsibility. On average are only on 10 tablets.
What contraindications are there for peritoneum dialysis?
Failure of peritoneal membrane, adhesions, hernia, stoma, patients unable to connect/disconnect, obese or large muscle mass (peritoneal ratio).
What complications are there for peritoneum dialysis?
Peritonitis, exit or tunnel site infections, ultrafiltration failure, leaks (scrotal and diaphragmatic) and development of hernia.
