摘要:

目的 分析无创心排血量监测(NICOM)与有创心排血量监测(Swan Ganz导管)测定的心指数(CI)和心排血量(CO)结果间的相关性,评价NICOM在临床麻醉监测中的应用价值。方法 选取接受不停跳冠状动脉搭桥择期手术患者36例,选取切皮前(T1)、打开胸腔(T2)、取乳内动脉(T3)、切开心包(T4)、吻合前降支(T5)、吻合对角支(T6)、吻合后降支(T7)、缝合心包(T8)和缝合胸腔(T9)9个时间点,分别用NICOM和Swan Ganz监测患者的CI和CO,对测定结果进行相关性分析。结果 在T1、T3、T4时间点,NICOM与 Swan Ganz监测CO的相关系数曲线比较拟合,相关系数分别为0.858、0.850、0.877(P<0.05);CI的相关系数曲线较一致,相关系数分别为0.752、0.819、0.804(P<0.05)。结论 在心脏解剖位置不变的条件下,NICOM与Swan Ganz的相关性较好,可为围术期目标管理提供无创、可靠的参考
依据。

Abstract:

Objective To explore correlation of cardiac output (CO) and cardiac index (CI) measured by noninvasive cardiac output monitoring (NICOM) and thermodilution (Swan Ganz catheter), and to assess clinical value of NICOM. Methods Thirty-six adult patients undergone off pump coronary artery bypass surgery were selected. CO and CI parameters were measured by NICOM and Swan Ganz catheter simultaneously at nine time points: before incision (T1), opening chest (T2), requiring internal mammary artery (T3), opening pericardia (T4), left anterior descending coronary artery bypass graft (T5), diagonal branches (T6), posterior descending branch (T7), closing pericardial (T8), and closing chest (T9). The correlation of CO and CI parameters were evaluated. Results At T1, T3, T4  time points, the coefficient curve was fit in 0.858, 0.850, and 0.877 of CO, 0.752, 0.819, and 0.804 of CI, respectively (P<0.05). Conclusion NICOM may provide accuracy references in perioperative period, which has complete correlation to Swan Ganz catheter.
