ABSTRACT
Intraaortic balloon pump (IABP) is one of the short-term circulatory mechanical support technique. This technique can increase the blood flow of the coronary arteries to improve the blood and oxy-gen supply to myocardium,reduce the cardiac afterload,increase cardiac output. This technique was first used on adult in 1967 and till 1980 doctor Pollock used it on children successfully. After that there were several reports of pediatric patients using IABP,most of them are patients with congenital heart disease who had low cardiac output syndrome postoperatively,others were cardiomyopathy,myocarditis and children waiting for a heart transplant, total survival rate was 25%-100%. For children who can′t wean from cardiopulmonary bypass,bridge to the use of ventricular assist or extracorporeal membrane oxygenation and heart transplant, left ventricle failure leads to low cardiac output,IABP can be used to improve cardiac output and reduce mor-tality. However,with maturing of extracorporeal membrane oxygenation and ventricular assist device,whether IABP is the best choice for early cardiac assistance needs to be further studied.
ABSTRACT
48 h) in the IABP Group (14/19) was significantly higher than that in the Control Group (19/45) ( ? 2=4 110, P =0 043). Conclusions In the absence of prophylactic IABP, OPCAB can be safely operated on in patients with low ejection fraction.
