The animal models are pivotal for understanding the characteristics of acute renal failure (ARF) and development of effective therapy for its optimal management. Since the etiology for induction of renal failure is multifold, therefore, a large number of animal models have been developed to mimic the clinical conditions of renal failure. Glycerol-induced renal failure closely mimics the rhabdomyolysis; ischemia-reperfusion-induced ARF simulate the hemodynamic changes-induced changes in renal functioning; drug-induced such as gentamicin, cisplatin, NSAID, ifosfamide-induced ARF mimics the renal failure due to clinical administration of respective drugs; uranium, potassium dichromate-induced ARF mimics the occupational hazard; S-(1,2-dichlorovinyl)-L-cysteine-induced ARF simulate contaminated water-induced renal dysfunction; sepsis-induced ARF mimics the infection-induced renal failure and radiocontrast-induced ARF mimics renal failure in patients during use of radiocontrast media at the time of cardiac catheterization. Since each animal model has been created with specific methodology, therefore, it is essential to describe the model in detail and consequently interpret the results in the context of a specific model.

Target controlled infusion (TCI) devices are increasingly used in clinical practice. These devices unquestionably aid optimization of drug dosage. ⋯ One has to realize the limitation of this approach: these models may be less accurate when applied to patients in extreme clinical conditions: in intensive care units, with a considerable loss of blood, severe hypothermia or temporary changes in the composition of plasma, e.g., hypoalbuminemia. In the future, data obtained under these "extreme" clinical circumstances, may be used to modify the dosage algorithms of propofol TCI systems to match the clinical scenario.
