Document Summary
Nutrition therapy to restore fluid and electrolyte balances and minimize toxic wastes building up in blood. Medications lower doses due to impaired renal function. Protein 0. 8-1. 2 grams per kg body weight/day for patients not treated with dialysis. Higher intakes once kidney function improves or treatment includes dialysis 1. 2-1. 5 g/kg/day. Calories 25 to 35 calories/kg body weight/day. Fluids measure urine output and add 500 ml to account for insensible water losses. Electrolytes sodium (2000-3000 mg), potassium (2000-3000 mg), phosphorus restrictions (8-15 mg per kg/day) and phosphate binders; serum electrolytes monitored. Possible enteral support using appropriate renal formula; parenteral support if needed (parenteral nutrition support used only if patients are severely malnourished or cannot consume food for more than 14 days. ) Indirect calorimetry provides the best estimate of energy needs. Monitor weight daily to help establish whether energy needs being met. Most common causes of htn and dm. Syndrome in which progressive loss of kidney function occurs.
