PiCCO监测技术在小儿支气管肺炎合并心力衰竭容量管理中的应用

Application of PiCCO monitoring technology in capacity management of children with bronchopneumonia complicated with heart failure

目的探讨脉搏指示连续心输出量监测(PiCCO)技术在小儿支气管肺炎合并心力衰竭容量管理中的应用。方法选取本院2019年1—10月收治的支气管肺炎合并心力衰竭患儿60例为研究对象,采用随机数字表法等分为观察组与对照组。观察组在PiCCO监测下行容量管理,对照组在中心静脉压(CVP)指导下行容量管理。比较两组患儿治疗前后心脏指数(CI)、胸腔内血容积指数(ITBVI)和血管外肺水指数(EVLWI),以及PICU住院时间和治疗后28 d病死率。结果治疗后,观察组CI高于对照组(P<0.05),ITBVI和EVLWI低于对照组(P<0.05)。观察组PICU住院时间短于对照组(P<0.05),28 d病死率低于对照组(P<0.05)。结论PiCCO监测下的容量管理应用于支气管肺炎合并心力衰竭患儿,可有效改善其血流动力学指标,降低病死率。

Objective To explore the application of pulse-induced contour cardiac output(PiCCO)monitoring technology in capacity management of children with bronchopneumonia complicated with heart failure.Methods To select 60 cases of children patients with bronchopneumonia and heart failure admitted to our hospital from January to October 2019 as the study subjects.They were divided into an observation group and a control group by random number table method.The observation group performed the capacity management under PiCCO monitoring,and the control group was guided the capacity management by central venous pressure(CVP).The cardiac index(CI),intrathoracic blood volume index(ITBVI)and extravascular lung water index(EVLWI),and the PICU hospital stay and the 28-day mortality after treatment of the two groups of children patients before and after treatment were compared.Results After treatment,the CI in the observation group was higher than that in the control group(P<0.05),and the ITBVI and EVLWI were lower than those in the control group(P<0.05).The PICU hospital stay in the observation group was shorter than that in the control group(P<0.05),and the 28-day mortality was lower than that in the control group(P<0.05).Conclusion The PiCCO monitoring capacity management applied to children patients with bronchopneumonia and heart failure could effectively improve their hemodynamic indicators and reduce mortality.
