Abstract:
Objective To investigate the blood-saving effect of tranexamic acid in patients undergoing Stanford type A aortic dissection surgery.Methods Fifty-six patients of both sexes with acute Stanford type A aortic dissection, aged 34-58 yr, weighing 62-84 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ , with their left ventricular ejection fraction ＞ 40％, undergoing emergency surgery, were randomly divided into 2 groups: control group (group C, n=26) and tranexamic acid group (group TA, n=30).Tranexamic acid was infused as a bolus of 10 mg/kg over 30 min before skin incision followed by an infusion of 10 mg · kg-1 · h-1 throughout the surgery in group TA.The equal volume of normal saline was given instead in group C.The total volume of drainage at 24 h after operation, the postoperative requirement of allogeneic red blood cells, fresh frozen plasma and platelets, and re-thoracotomy for bleeding were recorded.The postoperative mechanical ventilation time, duration of intensive care unit stay, and complications after operation were also recorded.Results Compared with group C, the total volume of drainage at 24 h after operation, and the requirement of allogeneic red blood cells, fresh frozen plasma and platelets were significantly reduced, the incidence of rethoracotomy for bleeding was decreased, the postoperative mechanical ventilation time, and duration of intensive care unit stay were shortened, and the incidence of postoperative acute lung injury and transient neurological dysfunction were decreased in group TA.Conclusion Tranexamic acid has blood-saving effect and can reduce postoperative bleeding and allogeneic blood transfusion in patients undergoing Stanford type A aortic dissection surgery.
