Hemodynamic monitoring by pulse-indicated continuous cardiac output analysis during pediatric cardiac surgery

Objective To evaluate the application of pulse-indicated continuous cardiac output(PiCCO) system in pediatric congenital heart disease surgery.Methods Ten patients aged 1-5 years old,underwent heart surgery under cardiopulmonary bypass(CPB) were investigated in the study. Hemodynamic parameters were monitored by PiCCO system before operation (T1), before CPB (T2),at 0.5 h (T3), 1 h (T4) and 24 h after CPB (T5).Catheter-related complications were recorded as well.Results There was no PiCCO catheter-related complication in any patient. There were no significant changes in heart rate between the two groups. The mean arterial pressure and cardiac index were lower at T3 than those at T1 and T2.Intrathoracic blood volume index and global end-diastolic volume index were lower at T4 than those at T1 and T2,while cardiac index of T4 increased significintly(P0.05). Conclusion PiCCO system is a safe, continuous, multiparameter invasive monitoring device for hemodynamic monitoring in pediatric heart surgery.
