Comparasion between deep hypothermic circulatory arrest and selective antegrade cerebral perfusion during pediatric aortic arch surgery

Abstract:

Objective：To evaluate the efficacy between deep hypothermic circulatory arrest（DHCA） and selective antegrade cerebral perfusion（SACP） used in pediatric aortic arch surgery. Methods：Sixty cases undergoing repair of coarctation of aorta or interrupted aortic arch complicated with cardiac monstrosity from January 2008 to March 2012 in our hospital were retrospectively reviewed. They were divided into two groups according to the method of cerebral protection：DHCA group（n=23） and SACP group（n=37）. Periopera－tive variables between the two groups were compared. Results：The lowest nasopharyngeal and rectal temperatures were significantly higher，postoperative intubation time was longer and thorax output during postoperative 24 h was larger in SACP group than in DHCA group（P<0.05）. There was no significant difference between two groups in terms of hospital mortality，occurrence of postoperative neurological complication，acute renal failure and low cardiac output syndrome（P >0.05）. Conclusions：Cerebral protective effect of DHCA and SACP in pediatric aortic arch surgery is comparable. SACP has the advantages of better recovery of respiratory function and less postoperative blooding.
