Negative effect of frusemide pretreatment in glycerol induced acute renal failure.
It is commonly assumed that the decrease in the effective circulatory volume (ECV) is the major event in acute renal failure (ARF) and the preferential ischemia of the cortex another major modification. Frusemide has been given to try to prevent this change in glycerol-induced ARF because of its effect in redistributing renal blood flow from medulla to cortex. Isontonic saline was also tried to avoid the ECV depletion. The pretreatment with frusemide not only fails to protect against the ARF but increases its severity. Isotonic saline adminstration and replacement of urinary losses almost prevent glycerol-induced ARF but when both isotonic  saline frusemide are administered together their effect is only a slight increase in the excretion rate of urea and creatinine during the first days of the experiment. The importance of the changes in the ECV or a possible direct action of frusemide on the renin-angiotensin axis are discussed. There is a good correlation between plasma creatinine levels and interstitial oedema. The importance of the oedema in the maintenance of ARF is discussed.
