Abstract:
Objective To observe and evaluate the effects of the deep hypothermic circulatory arrest(DHCA) and regional cerebral perfusion(RCP) in pediatric aortic arch surgery.Methods According to different methods of CPB,70 infants less than 3-month-old with CoA or IAA were undergone corrective surgery with DHCA or RCP.The bypass time,aortic clamp time,DHCA or RCP time,ventilation time,ICU stay time and post-operative complications were recorded and compared between two groups.Results The incidence of neurological complications was significantly higher in DHCA group.The CPB time was significantly longer in the RCP group,and the RCP time was significantly longer than DHCA time.Blocking time,ventilator intubation time,ICU residence time,postoperative renal dysfunction,low cardiac output,puhnonary inflammation and hospital mortality was no significant difference between the two groups.Conclusion RCP is an effective cerebral protection technique.Compared with DHCA,RCP works better in sustained brain cerebral perfusion and is suitable for complex aortic arch operation in children.It has a better effort in protection of the neurological system than DHCA.
