Perioperative acute kidney injury - cloaked and hidden - know your enemy

Surgery and anaesthesia come with adverse effects. As obvious as it is, not all of them are considered frequently enough. It may seem reasonable because some of them kill instantly. But others can kill too, simply silently and in a prolonged period. Acute kidney injury may seem to be a dull subject. Especially, when it does not lead to instantaneous complete loss of function. A disease that is a little bit intangible, with no pill that can directly treat it. Nevertheless, deterioration of kidney function may have a tremendous impact on patients' life. Even when it does not lead to renal replacement therapy. That is why we should be interested in recognising it and giving our patients as much as we can to neutralise its consequences. Do you know enough about this complication? When to expect creatinine to start rising? Diuresis - do you know how much is not much enough? Let us dive together into this trite, yet important subject.
