摘要:

目的: 探讨氨甲环酸联合急性等容量血液稀释(ANH)对非体外循环冠脉旁路移植术(OPCABG)患者的影响。方法: 择期OPCABG手术患者60例,ASA II~III 级,年龄45~70岁,BMI 20~23 kg/m2,随机分为3组(n=20):对照组(C组)、氨甲环酸组(T组)、氨甲环酸联合ANH组(T+A组)。C组不做处理;T组于麻醉诱导后30 min内采用静脉注射负荷量20 mg/kg氨甲环酸,然后以10 mg·kg-1·h-1输注至术毕;T+A组采用氨甲环酸和ANH联合应用。依次记录术前和术毕、术后24 h Hb,红细胞压积(Hct),Plt, 凝血酶原时间(PT)和国际标准化比值(INR)等凝血功能指标以及D-二聚体的变化,以及术后6、24 h胸管引流量,记录术后24 h内异体红细胞和新鲜冰冻血浆输注等情况。结果: 与C组比较,T组和T+A组术毕和术后24 h时D-二聚体浓度下降,术后胸管引流量、异体红细胞的使用率和使用量降低(P<0.05);各组间各时点Hb、Hct、Plt和INR差异无统计学意义(P>0.05)。与T组比较,T+A组术后胸管引流量、异体红细胞和血浆使用量降低(P<0.05)。3组未见住院期间死亡和相关并发症的发生。结论: 氨甲环酸联合中度ANH可以产生协同节约用血的效果,对OPCABG手术患者凝血功能无明显影响。

Abstract:

AIM: To investigate the effect of tranexamic acid plus acute normovolemic hemodilution (ANH) in off-pump coronary artery bypass grafting (OPCABG) patients.  METHODS: Sixty ASA physical status II-III patients,aged 45-70 years,with body mass index of 20-23 kg/m2, scheduled for elective undergoing OPCABG were randomly divided into 3 groups (n=20): control group (group C), tranexamic acid group ( group T), tranexamic acid combined with ANH group (group T+A). Group C received no treatment. After induction of anesthesia, tranexamic acid 20 mg/kg was intravenously infused in 30 min followed by continuous infusion at 10 mg·kg-1·h-1 until the end of operation in group T. Tranexamic acid was intravenously infused combined with ANH in group T+A. Coagulation parameters such as Hb, Hct, Plt, PT, INR and D-dimer were recorded before operation, after operation and 24 h after operation, respectively. The volume of chest tube drainage was collected and recorded at 6 h and 24 h after operation. The transfusion of allogeneic red blood cells and fresh frozen plasma within 24 h were also recorded. RESULTS:Compared with group C, the D-dimmer level decreased significantly in group T and group T+A right after the operation and 24 h after the operation, and the volume of chest tube drainage as well as the requirement for transfusion of allogeneic red blood cells were reduced (P<0.05). No significant changes were found in Hb, Hct, Plt and INR at each time point between all groups (P>0.05). Compared with group T, the volume of chest tube drainage and the requirement for transfusion of allogeneic red blood cells were reduced (P<0.05) in group T+A. No development of death and complications during days of hospitalization was observed in the three groups. CONCLUSION: Tranexamic acid combined with ANH exhibit a synergistic effect of blood-saving and has no significant effect on coagulation function of patients undergoing OPCABG surgery.
