Title: Management of cardiopulmonary bypass in infant with tetralogy of Fallot
Abstract: Objective To disccus the cardiopulmonary bypass in infants with tetralogy of Fallot(TOF) in open heart surgery.Methods 71 cases of the cardiopulmonary bypass within 10kg in infants with TOF were summarized.Moderate hypothermia and profound hypothermia low flow perfusion CPB were performed according different procedures.Heart arrest were by 4:1 cold blood fluid through aortic root,paralleled and modified ultrafiltration were executed after rewarming.Results 16 cases were operated with moderate hypothermia and 54 cases with profound hypothermia low flow perfusion during the TOF surgical procedures.CPB time was 59-243min.Clamped time was 39-126min.One case was performed with TOF surgical procedures with 5 min hypothermia arrest and 114 min CPB,which clamped time was 56min.68 cases(95.8%) recovered heart beating automaticly after clamp removed,6 cases retied CPB formidable.The mortalities of infants was 2.8%(2/71).Conclusion Reasonable priming,high quality of membrance oxygenator during CPB,proportionate hemodilution,profound hypothermia low flow perfusion CPB and modified ultrafiltration were crucial factors to improve CPB for TOF procedures in infants.
