动态监测早期休克新生儿左心排量变化及临床意义

The clinical significance and dynamic monitoring of left cardiac output changes of newborns with early shock

目的：研究动态监测早期休克新生儿左心排量变化的临床意义。方法选取我院2013年1月-2014年8月入院治疗的35例早期休克新生儿为观察组，另选取同期出生的新生儿35例为对照组。临床应用超声心排出量监测仪（USCOM）技术无创监测两组新生儿的左心输出量及每搏输出量。观察组患儿应用扩容及多巴胺治疗。对比两组新生儿的左心排量变化及观察组患儿治疗前后的左心排量变化。结果两组患儿治疗前左心排量为（0.38±0.23）L/min vs（0.48±0.16）L/min，差异有统计学意义（P＜0.05）。观察组患儿治疗后左心排量较治疗前升高，治疗前后分别为（0.38±0.23）L/min vs（0.53±0.27）L/min，差异有统计学意义（P＜0.05）。结论动态监测新生儿左心排量变化，可以早期发现并及时治疗新生儿休克。

Objective To analyze and investigate the clinical significance of dynamic monitoring of cardiac output changes of newborn with early neonatal shock. Methods 35 newborns with early neonatal shock admitted in our hospital from January 2013 to August 2014 were selected as an observation group, another 35 cases of newborns born in the same period were selected as a control group. The left cardiac output and stroke volume of newborns between the two groups were technologically noninvasive monitored using ultrasonic cardiac output monitor （USCOM） by clinic. The observation group received treatment of expansion and dopamine. Changes in left ventricular displacement between before and after treatment of the observation group and left cardiac output changes between the two groups were compared. Results The left cardiac output before treatment between the two groups were （0.38±0.23）L / min and （0.48±0.16） L/min, with a statistically significant difference（P 〈 0.05）. The left cardiac output of the observation group after treatment was higher than that before treatment, that after treatment respectively were （0.38±0.23） L/min and （0.53±0.27）L/min, with a statistically significant difference（P 〈 0.05）. Conclusion Neonatal dynamic monitoring changes in left ventricular displacement, is early detection and timely treatment of neonatal shock.
