Title: The Application of Exchange Between Cardiopulmonary Bypass and Closed Extracorporeal Circulation during Operation on Heart
Abstract: Objective To introduce the method and effect of common cardiopulmonary bypass(CPB) switched to closed extracorporeal circulation by medtronic extracorporeal membrane oxygenation(ECMO) package. Methods From Junuary 2007 to June 2008,common CPB switched to closed extracorporeal circulation by Medtronic ECMO package adding blood reservoir and artery microembolus filtrator was used to 15 patients with grave heart disease to provide CPB support during operation on heart and cardiac function support after operation. The circulation was built through femoral artery-femoral vein-superior vena cava intubation or aorta-right auricle intubation. There were 10 male and 5 female aged from 65-82 years (74.0±9.3 years) and weighed from 63-89 kg (69.0±11.4 kg). There were 11 cases with old myocardial infarction,1 case with acute myocardial infarction,1 case with old myocardial infarction complicated with mitral stenosis and mitral incompetence,and 2 cases re-opened and undergone double valve replacement. Results For all the 15 patients,the closed circulation time was 31-112 min(77.3±21.5 min). The CPB time was 51-84 min(69.7±9.8 min). The postoperative mechanical ventilation time was 4-14 h(8.3±2.9 h). The 24 h-chest drainage was 110-360 ml(227.3±80.4 ml). All patients were cured and discharged successfully with cardiac function classification in grade Ⅰ-Ⅱ. Thirteen cases were followed up. The follow-up time was 4-12 months. Their cardiac function recovered well and no complication occurred. Conclusion This method could provide effective support for heart and lung before operation,during operation and after operation. This method could save material cost. The heparin paintcoat could reduce inflammatory reaction and it is good for patients' recovery.
