目的探讨重症肺炎并呼吸衰竭患儿中应用动态无创肺动脉压力监测的效果及临床意义。方法将2015年1月—2016年12月在南阳市卧龙区妇幼保健院进行治疗的68例重症肺炎并呼吸衰竭患儿作为研究对象,根据患儿是否有肺动脉高压分成观察组38例(有肺动脉高压)与对照组30例(无肺动脉高压),两组患儿治疗前后均采用彩色多普勒无创动态超声对肺动脉压力进行监测,分别对两组患儿的机械通气情况及治疗前后的肺动脉压力进行统计对比。结果观察组机械通气率、死亡率及通气时间分别为78.9%、18.4%、(8.24±1.91)d,明显高于对照组,差异有统计学意义(P<0.05);治疗前两组患儿的肺动脉压力存在明显的差异,治疗后观察组患儿的肺动脉压力得到明显提升,差异具有统计学意义(P<0.05)。结论动态无创肺动脉压力监测可对重症肺炎并呼吸衰竭患儿的肺动脉压力进行快速检测,还可以很好的反映患儿病情进展,有助于临床治疗指导,改善患儿预后。
Objective To investigate the effect and clinical significance of dynamic noninvasive pulmonary artery pressure monitoring in children with severe pneumonia and respiratory failure. Methods From January 2015 to December 2016, 68 children with severe pneumonia and respiratory failure who were treated in Wolong District Maternal and Child Health Hospital of Nanyang City were enrolled. According to whether the children had pulmonary hypertension, 38 cases were divided into observation group (with pulmonary artery High pressure) and control group (no pulmonary hypertension). Both groups were monitored by color Doppler noninvasive dynamic ultrasound before and after treatment. Mechanical ventilation and pulmonary artery pressure before and after treatment were compared between the two groups Statistical comparison. Results The mechanical ventilation rate, mortality rate and ventilation time in the observation group were 78.9%, 18.4% and 8.24 ± 1.91 d respectively, which were significantly higher than those in the control group (P <0.05) There was a significant difference in pulmonary artery pressure. After treatment, the pulmonary artery pressure of the observation group was significantly improved, with statistical significance (P <0.05). Conclusions Dynamic noninvasive pulmonary artery pressure monitoring can detect pulmonary artery pressure in children with severe pneumonia and respiratory failure. It can also reflect the progress of the disease in children and help to guide clinical treatment and improve the prognosis of children.
