摘要:
ObjectiveTo investigate the effect of tranexamic acid on inflammatory response in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods Sixty ASA Ⅰ -Ⅲ and NYHA Ⅰ -Ⅲ patients of both sexes,aged 45-64 yr,with body mass index 16-22 kg/m2,undergoing elective OPCABG,were randomly divided into 2 groups ( n =30 each):control group (group C) and tranexamic acid group (group T).Anesthesia was induced with iv injection of midazolam,fentanyl and pipecuronium.The patients were tracheal intubated and mechanically ventilated.PETCO2 was maintained at 35-45 mm Hg.Tranexamic acid 1 g was infused intravenously over 30 min after induction followed by continuous infusion at 400 mg/h until the end of operation in group T.While equal volume of normal saline was given in gtoup C.Anesthesia was maintained with inhalation of isoflurane and intermittent (i)v boluses of fentanyl and pipecuroninm.Venous blood samples were taken before induction,at the end of operation and 24 h after operation for determination of Hb,platelet count,prothrombin time,international normalized ratio and plasma D-dimer and IL-6 concentrations.The volume of chest tube drainage was collected and recorded at 6 and 24 h after operation.The requirement for transfusion of allogeneic red blood cells and fresh frozen plasma was recorded.The complications during hospital stay were also recorded.ResultsCompared with group C,the plasma concentrations of D-dimer and IL-6 were significantly decreased at the end of operation and 24 h after operation,and the volume of chest tube drainage and the requirement for transfusion of allogeneic red blood cells and fresh frozen plasma were significantly decreased after operation in group T ( P ＜ 0.05 or 0.01).There was no significant difference in Hb,platelet count,prothrombin time and international normalized ratio between the two groups (P ＞ 0.05).No complications occurred during hospital stay in the two groups.ConclusionTranexamic acid can reduce inflammatory response in patients undergoing OPCABG.
