Serum lactate and capillary refill time as predictors of acute kidney injury after pediatric cardiovascular surgery: a prospective cohort study

Listen to this summary

The authors aimed to identify early, modifiable predictors of acute kidney injury (AKI) in children undergoing cardiovascular surgery. Their prospective cohort study found that elevated serum lactate levels and prolonged capillary refill time at ICU admission were significant predictors of AKI, highlighting the potential for these accessible measures to aid in early risk stratification and inform kidney protective strategies.
