Revision Flashcards
Kidney functions
Eryropeitin production-produces RBCs Regulating arterial pressure Acid /base balance Water and electrolyte balance Glucose synthesis Excretion - metabolic waste products and foreign chemicals Calcium excretion Production of vit D
Pre renal cause of acute renal failure
Hypovolaemia, decreased BP due to anaesthesia
Intrinsic renal cause for acute renal failure
Poison affecting kidney cells themselves e. G ethylene glycol, lilies, e. Coli pyelonephritis (usually ascending from lower tract)
Post renal acute renal failure
Blockage in ureter (urethral stone), blocked bladder, blocked d urethra, rupture of ureters or urethra
Nutritional management for chronic renal failure
Suitable controlled protein Low phosphorous Palatable food Phosphate binders eg. Ipakitine Anti emetics, vit b, eryhthropoetin, electrolyte supplements usually potassium
Care if obstructive feline lower urinary tract disease
Stabilise with iv fluids no potassium NOT HARTMANNS
Hyperkalaemia is a side effect of glomerular filtration ceasing due to back pressure of urine inside the kidney
Once stable, GA not sedation clip and surgical prep urethral area and vs will catheterise
Diet in congestive heart failure
Moderate sodium restriction
Mild sodium restriction in sever heart failure
High quality protein
Potassium and magnesium can both impact negatively on heart rhythm and contractility when depleted.
Omega three fatty acids can be helpful to modulate effects of cardiac cachexia and may also have an anti arrhythmic effect
Nutrition and kidney disease
Protein and phosphorous restriction
Protein restriction to minimise the load of urea on body that needs to be excreted by kidneys.
Increased blood urea due to poor renal excretion can lead to clinical signs associated with CRF like inapptence and vomiting
