Bioz.com用于心脏手术围术期监测的临床价值研究(1)
摘要：目的 评价无创血流动力学监测系统(Bioz.com)用于心脏手术患者围手术期心功能评估的准确性及可靠性。方法 选取在2017年12月～2018年6月于承德医学院附属医院行择期心脏手术患者35例，包含瓣膜性疾病23例，冠心病12例。选取“肺动脉漂浮导管”及“超声心动图”作为比较指标，严格按照Bioz.com系统操作规范进行操作，对心排出量(CO)、每搏输出量(SV)、心指数(CI)进行监测，分别记录手术前后患者血流动力学变化情况，并进行相关统计学分析。结果 心脏手术前后，采用 Bioz.com系统及超声心动图两种方法对患者血流动力学参数CO、SV、CI进行监测并比较，差异均无统计学意义(P>0.05)。心脏手术中，采用Bioz.com系统及漂浮导管两种方法对患者血流动力学参数CO、SV、CI进行监测并比较，差异均无统计学意义(P>0.05)。结论 在心脏手术中Bioz.com系统与肺动脉漂浮导管，Bioz.com系统与超声心动图监测的精确度与准确度具有一致性，是一种较为可行的心功能监测方法。

Abstract：Objectives To evaluate the accuracy and reliability of the non-invasive hemodynamic monitoring system (Bioz.com) for perioperative cardiac function assessment in patients undergoing cardiac surgery. Methods From December 2017 to June 2018， 35 patients underwent elective cardiac surgery at the Affiliated Hospital of Chengde Medical College， including 23 patients with valvular disease and 12 patients with coronary heart disease. The "pulmonary artery floating catheter" and "echocardiogram" were selected as comparison indicators， and the operation was carried out in strict accordance with the Bioz.com system operation specification. The cardiac output (CO)， stroke volume (SV)， and heart index (CI) were monitored. The hemodynamic changes of patients before and after surgery were recorded and statistical analysis was performed. Results Before and after cardiac surgery， the hemodynamic parameters CO， SV and CI were monitored and compared by Bioz.com system and echocardiography，the differences were not statistically significant (P>0.05). In the cardiac surgery， the hemodynamic parameters CO， SV and CI were monitored and compared by Bioz.com system and floating catheter，the difference was not statistically significant (P>0.05). Conclusion In the cardiac surgery， the Bioz.com system and the pulmonary artery floating catheter， Bioz.com system and echocardiography monitoring are consistent with the accuracy and accuracy， which is a feasible method for heart function monitoring.

在心臟手术监测血流动力学情况的手段中，Swan-Ganz漂浮导管始终扮演者十分重要的角色，但它具有创伤性、且需要操作者具有一定的技术基础[1]。超声心动图具有一定的准确性与实用性，但是缺乏连续性[2]。Bioz.com是无创血流动力学监测系统技术是近年来新兴的血流动力学监测方法，具有能连续测量、无创伤、能实时监测、费用低、操作简单等特点[3]，其精确度与用有创方法测得的参数具有良好的相关性。但是Bioz.com系统在心脏手术，尤其是在瓣膜置换手术患者围术期的心功能评价方面报道还较少[4]。因此，于2017年12月～2018年6月，本研究就心脏手术前后 Bioz.com与超声心动图及漂浮导管对围手术期中相关血流动力学指标进行监测并比较，以观察Bioz.com系统监测血流动力学相关指标的准确性及可靠性。, 百拇医药(赵悦 董婕 韩晨阳 周国明)
