Answer

The mortality rate in patients with ATN is probably related more to the severity of the underlying disease than to ATN itself. For example, the mortality rate in patients with ATN after sepsis or severe trauma is much higher (about 60%) than the mortality rate in patients with ATN that is nephrotoxin related (about 30%). The mortality rate is as high as 60-70% with patients in a surgical setting. If multiorgan failure is present, especially severe hypotension or acute respiratory distress syndrome, the mortality rate ranges from 50 to 80%.
