Does absolute hypotension increase the risk of postoperative acute kidney injury in adult patients undergoing noncardiac surgery?
Absolute, rather than relative, hypotension is an independent risk factor for postoperative acute kidney injury in adults undergoing noncardiac surgery.
Adult patients undergoing noncardiac surgery demonstrate varying associations with distinct levels of hypotension when stratified by preoperative risk factors. Specific levels of absolute hypotension, but not relative hypotension, are an important independent risk factor for acute kidney injury.
