Comparison of curative effects and prognosis between coronary artery bypass grafting with and without cardiopulmonary bypass / 中国医师杂志

ABSTRACT

Objective To investigate the difference of curative effects and prognosis between coronary artery bypass grafting with and without cardiopulmonary bypass.Methods 152 patients who were operated using off-pump coronary artery bypass grafting (OPCABG) and 107 patients who were performed with on-pump coronary artery bypass grafting (CABG) in the authors'department during the period from October 2013 to October 2017 were included in the study.The differences of postoperative recovery and major complications between the two groups were analyzed.Results Compared with CABG group,patients in OPCABG group had shorter intensive care unit (ICU) monitoring time,electrocardio-monitoring time,duration of antibiotic treatment,time of drainage tube intubation,mechanical ventilation time,arterial piezometer tube monitoring time and length of hospital stay (P ＜ 0.05).And postoperative draining fluid volume in patients of OPCABG group was also less than that in CABG group (P ＜ 0.05).Additionally,there was no difference between the two groups in postoperative parameters including renal insufficiency,using intra-aortic balloon pump (IABP) machine,perioperative myocardial infarction,second operation for hemorrhage,the occurrence of postoperative arrhythmias and cerebrovascular accident (P ＞ 0.05).However,the incidence of postoperative pulmonary infection was significantly higher in patients of CABG group than that in OPCABG group (P ＜ 0.05).Conclusions The incidence of postoperative pulmonary infection was significantly decreased in OPCABG group compared with that in CABG group.And the postoperative recovery of patients undergoing off-pump coronary artery bypass grafting was superior to that of patients undergoing onpump coronary artery bypass grafting.
