Comparative studies on perioperative hemodynamics in coronary artery bypass with or without cardiopulmonary bypass / 解放军医学杂志

ABSTRACT

Objective To analyze the hemodynamic changes during coronary artery bypass grafting with or without cardiopulmonary bypass.Methods Thirty patients undergone coronary artery bypass grafting from January to June,2006 were retrospectively analyzed.Among them,12 patients were operated on with cardiopulmonary bypass(CCABG)and 18 without cardiopulmonary bypass(OPCAB).The stabilizator(type Octops III)was used to fix target vessels in OPCAB group.In CCBAG group,the extracorporeal circulation was used routinely,and internal mammary artery and saphenous vein were used to anastomose with target branches of coronary artery.The hemodynamic changes at different time points during and after operation were monitored,and the relevant parameters were also recorded.Results The anaesthesia time,intraoperative blood loss and fluid input,and ventilating time after operation in CCABG group were significantly higher than those in OPCAB group,and the postoperative haematocrit(HCT)was significantly lower in CCABG group than that in OPCAB group(P
