Introduction: Lactic acid is considered as an early indicator of survival and/or mortality in patients with cardiovascular surgical procedures. Objectives: To determine behavior of lactic acid in arterial blood during pediatric cardiac surgery, and the prognosis of such patients when are discharged of intensive care unit. Material and Methods: We made a prospective, analytical and observational study of 55 pediatric patients undergo extracorporeal circulation in "William Soler" Children Cardiac Center. We took samples of arterial blood at the end of anesthesia induction (initial lactic acid), extracorporeal pre-circulation, and at the end of it. We considered the hyperlactacidemia when the lactic acid value in arterial blood was higher 3 mmol/L during the immediate intra- and postoperative period. Results: Lactic acid quantization in different times of surgical procedure was significant for the initial value of intraoperative period, and that of the extracorporeal circulation, but not for its relation with the value at the end of it. It was possible to demonstrate that the type of cardiopathy was not associated with the discharge status. Conclusions: Perioperative lactacidemia is an early indicator of survival in these patients. Serum lactate values during extracorporeal circulation were higher when it is used lactated ringer in primer solutions. The type of cardiopathy is not a predictor factor of survival.
