Introduction: There is discordant information on the ability of lactate to predict mortality in paediatric population after cardiac surgery. Objectives: To determine whether the peak serum lactate level measured in the first 24 postoperative hours is a predictive factor for mortality in intensive care in children and adolescents after cardiac surgery at the Instituto Nacional de Salud del Niño San Borja, Lima-Peru, and to calculate the lactate cut-off point with better sensitivity and specificity. Materials and methods: Retrospective cohort study. A Receiver Operating Characteristics (ROC) analysis was performed to determine the predictive capacity of lactate for mortality, then a crude and adjusted Poisson regression model was used. Results: The clinical history of 173 children and adolescents was evaluated, of whom 20 (11.6%) died. An AUC of 0.872 with a cut-off point of 4.95 mmol/L lactate was obtained to predict ICU mortality with a sensitivity of 85% and specificity of 82.4%. Patients who had a peak lactate level greater than 4.95 mmol/L during the first 24 hours post-operatively have 11 times the risk of ICU death. Conclusion: A peak lactate level greater than 4.95 mmol/L measured in the first 24 hours post-operatively has a good predictive value for mortality in children and adolescents post-operated cardiac surgery, so it is considered a recommended test for ruling out mortality in this population.
