title: [Renal failure--concepts for drug therapy in intensive care].
abstract: This article describes concepts of drug treatment for patients with severe renal failure (creatinine clearance less than 10 ml/min), especially in intensive care. These subjects often develop multiorgan failure and require special considerations: 1. Not only should the maintenance dose of digoxin be reduced to 0.05-0.1 mg/day, but the loading or digitalizing dose should also be diminished to 0.4-0.6 mg. 2. Penicillins, cephalosporins, quinolones, and other antibiotics with a high therapeutic ratio can be given as recommended by the manufacturer or reference lists according to renal insufficiency. 3. For drugs with a low therapeutic index, such as aminoglycosides, vancomycin, flucytosine, some antiarrhythmic agents, cardiac glycosides, and theophylline, therapeutic drug monitoring is mandatory. 4. Steroids, insulin, atropine, catecholamines, anticoagulants, thrombolytic agents, antihypertensive drugs, and organic nitrates can be given according to their effect. However, nitroprusside should be discontinued after 2 days because its metabolites may be toxic. 5. The dose of H2-receptor antagonists used for the control of gastric acidity and the treatment of peptic ulcers should be reduced to 20-50% of the normal. The administration of aluminum, magnesium, and bismuth compounds should be avoided. 6. Loop diuretics (e.g., furosemide) can be effective at increased doses in patients with chronic renal failure and fluid overload, particularly when used in combination with a thiazide in refractory edema. Thiazides alone are useless, and potassium-sparing diuretics are contraindicated. 7. Colloid-containing solutions should be infused cautiously at a maximal rate of 2 x 500 ml/week only when the plasma volume is contracted.(ABSTRACT TRUNCATED AT 250 WORDS)
