Low cardiac index during periods of arterial hypotension and risk of acute kidney injury in cardiac surgery
Listen to this summary
The authors aimed to investigate the relationship between low cardiac index (CI) during periods of arterial hypotension and the risk of acute kidney injury (AKI) in patients undergoing cardiac surgery. Their findings indicate that exposure to joint hypotension and low CI (≤2 L min⁻¹ m⁻²) significantly increases the risk of AKI and length of stay in the ICU and hospital, suggesting a potential need for CI-guided therapy to mitigate these risks.
