Abstract：Objective To summarize the management of extracorporeal circulation ( ECC) for infants below 10 kilograms un?dergoing open heart operation . Methods There are 80 infants below 10 kg who received the open heart operations in our department from December 2013 to March 2015. Imported oxygenator and ultrafilter were used in all patients. Crystalloid solution and albumin solu?tion were used as the pre-filling solution. ECC was conducted with mild to moderate hypothermia and median to high perfusion flow. The histidine-tryptophan-ketoglutarate solution was applied for myocardial protection through aortic root. Conventional and modified ul?trafiltrations were applied in all cases. Results The cardiopulmonarybypass time was 25-134 (71±29.4) min.The aorta crossclamping time was 20-106 (51.8±21.1) min. Sixty-fourpatients spontaneous resuscitated (94.2%) and electrical defibrillation was used in 4 patients. All children successfully weaned from the bypass machine and was stable during ECC. Conclusion Management of consuma?bles, pre-filling, perfusion and organ protection should be strengthened in the ECC of infants with congenital cardiopathy who were be?low 10 kg in order to reduce the occurence of postoperative complications and the death rate.Reasonable priming perfusion and hemodi?lution,suitable perfusion flow and pressure, management liquid of input-output, and myocardial protection were effective ways in ECC management of infants with congeniml heart disease who have low body weight.
