What to do with ischemic renal failure?

The treatment of ischemic renal failure should be approached with caution by all patients. Treatment must be targeted at the cause, and hypertension and acidosis must be corrected. If dehydration occurs, electrolyte imbalance must be corrected in a timely manner, water must be restricted, and weight must be controlled.

1. Treatment methods

① Treatment is targeted at the cause, such as volume expansion to correct pre-renal factors and eliminate post-renal obstructive factors. Severe acute or other glomerulonephritis can be effectively treated with hormone shock. Allergic interstitial nephritis should immediately stop taking the medication and give anti-allergic drugs, etc.

② During the oliguria period, the principle of fluid intake is to keep the amount of fluid out as the amount of fluid in.

③Correct hyperkalemia and acidosis.

④ Start dialysis therapy as early as possible, which has the functions of dehydration, removal of toxins, correction of electrolyte imbalance and acid-base imbalance, and enables patients to overcome the difficulties of the oliguria period. During the polyuria period, water and electrolyte balance should be strictly monitored to prevent death from dehydration and electrolyte imbalance. During the recovery period, it is very important to pay attention to strengthening nutrition, rest and avoiding the use of nephrotoxic drugs.

2. Diet and Health Care

1. Limit water intake: If the amount of urine excreted decreases, the fluid taken in through the mouth will be retained in the body, causing edema, high blood pressure, and even pulmonary edema. At this time, the daily fluid intake must be limited. Usually, the amount of fluid taken in through the mouth is approximately equal to the daily urine output plus 500cc.

2. High-quality low-protein diet: A high-quality protein diet is recommended for patients with chronic renal failure, that is, protein rich in essential amino acids. Such as milk, eggs, lean meat, fish, etc. Protein intake should be adjusted according to the patient's creatinine clearance. The recommended protein intake is generally 0.6 grams per kilogram of body weight. For example, if you weigh 50 kilograms, your daily protein intake should be controlled at 30 grams. At the same time, under strict restrictions on protein intake, protein sources must be carefully selected so that they can be fully utilized by the human body. It is recommended that at least 2/3 of the daily allowance be supplied by high-quality protein. Foods rich in plant protein such as peanuts, beans and their products: tofu, dried tofu, soy milk, bean curd skin, etc. should be used with caution.
