Objective To improve the management strategy for the infants with low weight and decreased pulmonary artery blood flow undergoing cardiopulmonary bypass( CPB). Methods The clinical data of 38 infants including age,body weight,operation type and CPB conditions including equipment,composition of priming liquids,duration of CPB and clamping time of ascending aorta were retrospectively analyzed,who were less than 5 kg in body weight and underwent CHD operations. The infants aged 20 days to 8 months,weighed 2. 6 ~ 5. 0 kg. All cases used mild hypothermia and moderate hypothermia,Modified ultrafiltration( MUF) and Balanced ultrafiltration( BUF) was used in all patients. Results After cross clamping release,heart beat recovered spontaneously in 34 patients without severe arrhythmia. 38 cases were successfully weaned from CPB without severe complications. Conclusion Appropriate infant bypass,low prime volume,keeping high HCT and colloidal pressure adapted perfusion flow rate matching temperature,myocardial preservation and pulmonary protection during CPB,MUF and BUF can lead to good results.
