非体外循环冠状动脉旁路移植术围术期输血的术前预测

Preoperative prediction of perioperative transfusion in off-pump coronary artery bypass graft

目的探讨非体外循环冠状动脉旁路移植术(OPCAB)围术期输血的术前预测指标。方法回顾分析了120例行OPCAB患者的临床资料,通过受试者工作曲线(ROC)分析红细胞比容(Hct)体重乘积预测围术期输血的最佳临界值及预测围术期输血发生的灵敏度和特异度。结果 120例病例对照研究的患者术后输血15例,发病率为12.5%,ROC曲线下面积0.836,根据ROC曲线选定22.559为最佳临界值,预测围术期输血的灵敏度为47.38%,特异度95.88%。结论 Hct体重乘积对OPCAB围术期输血有较强的预测意义,Hct体重乘积>22.559的患者OPCAB围术期输血发生率低。

Objective To identifypreoperativeprediction index of perioperative transfusion in off-pump coronary artery bypassgraft.Methods Clinical data was retrospectively collected and analyzed from patients who underwent off-pump coronary artery bypassgraft（OPCAB） between August 2014 and December 2014.Receiver operating characteristic curve（ROC） was used to estimate optimaloperating point（ OOP）, sensitivity and specifility for predicting preoperative transfusion.Results The morbidity of perioperativetransfusion in retrospective clinical data was 12.5%. Area under the curve of ROC was 0.836. Meanwhile, 22.559 was selected as OOPbased on ROC.The sensitivity and specifility of predicting preoperative transfusion were 47.38% and 95.88% respectively.Conclusion Product of hct and weight on the preoperativeprediction of perioperative transfusion in OPCAB is powerful. The morbidity of perioper-ative transfusion in OPCABis lower when Product of hct and weight is more than 22.559.
