Abstract:
Objective To identify the risk factors for early postoperative elevation in body temperature in patients undergoing coronary artery bypass grafting (CABG).Methods Nine hundred and forty-one patients of both sexes,aged 14-70 yr,were assigned into hyperthermia (≥ 38 ℃) group or non-hyperthermia (＜ 38 ℃) group according to the bladder temperature at 8h after operation.Factors including age,sex,height,weight,complications (hypertension,hyperlipemia,diabetes),history of smoking and drinking,preoperative blood pressure,heart rate,ejection fraction,routine blood examination,routine urine examination,and respiratory function examination,intraoperative cardiopulmonary bypass (CPB) and hormone,operation time,extubation time,duration of stay in the intensive care unit,and blood pressure,heart rate,ejection fraction,routine blood examination,and routine urine examination at the end of operation,and postoperative analgesia were recorded.The risk factors of which P values were less than 0.05 would enter the multi-factor logistic regression analysis to stratify the risk factors for early postoperative elevation in body temperature after CABG.Results Six hundred and ninety patients developed early postoperative elevation in body temperature (73.3％).Logistic regression analysis showed that preoperative respiratory dysfunction,preoperative ejection fraction ≤ 50％ and CPB were independent risk factors for early postoperative hyperthermia after CABG (P ＜ 0.05).Conclusion Preoperative respiratory dysfunction,preoperative ejection fraction≤ 50％ and CPB are independent risk factors for early postoperative elevation in body temperature in patients undergoing CABG.
