多普勒心脏超声在感染性休克患者容量反应性检测中的应用

The application of Doppler echocardiography in the measurement of volume responsiveness in patients with septic shock

目的 研究多普勒心脏超声在感染性休克患者容量反应性检测中的有效性.方法 选择2015—2016年我院收治的感染性休克患者30例作为研究对象,进行被动抬腿试验后,分别进行PICCO检测与多普勒心脏超声检测,比较患者心率、心输出量、中心静脉压、平均动脉压、每搏输出量等指标.结果 30例患者中,被动抬腿试验应答者20例,未应答者10例;应答者被动抬腿试验前、后心率、每搏输出量和心输出量比较,差异有统计学意义（P〈0.05）;未应答与应答者被动抬腿试验前、后,两种方法检测的血流动力学指标无明显差异（P〉0.05）.结论 多普勒心脏超声对感染性休克病人在进行被动抬腿试验后容量扩张反应性有较好的检测作用,值得推广应用.

Objective To explore the effect of Doppler echocardiography in the measurement of volume responsiveness in patients with septic shock. Methods A total of 30 cases of patients with septic shock in our hospital from 2015 to 2016 were selected as research objects. All patients were given the passive leg raising test, and the heart rate, cardiac output, central venous pressure, mean arterial pressure, cardiac stroke volume and other indicators were detected by PICCO and Doppler echocardiography. Results There were 20 respondents and 10 non-responders of the total 30 patients after passive leg raising test. Compared the heart rate, cardiac stroke volume and cardiac output of the respondents before and after passive leg raising test between the two groups, the differences were statistically significant （P〈0.05）. Both of non-responders and respondents, there was no significant difference in hemodynamic parameters between the two detection methods before and after passive leg raising test （P〉0.05）. Conclusion Doppler echocardiography has a good detection effect in the measurement of volume responsiveness in patients with septic after shock passive leg raising test, which is worthy of popularization and application.
