Serum lactate as mortality and morbidity marker in infants after Jatene's operation.

Objective: To assess the morbidity and mortality after Jatene's operation using lactate as the main marker.

Methods: We performed a historical cohort with infants admitted in a pediatric intensive care unit during 1995 to 2005 who underwent this surgery. We assessed the preoperative, immediate (IPD), third hour (3h), six hour (6h) and first day (POD1) serum lactate as well as other factors such as sepsis, increased bleeding, low cardiac output syndrome, renal insufficiency, pulmonary hypertension, cardiac arrythmias, chylothorax, myocardial ischemia, seizures, presence of other complication, and also information about length of PICU stay and death.
