目的:探讨连续无创血流动力学监测对新生儿呼吸窘迫综合征(NRDS)使用血管活性药物的指导及疗效.方法:采用随机数字表法,将2020年1月～2020年7月我院收治的50例NRDS患儿分为2组,各25例.两组均予以经鼻持续气道正压通气(NCPAP)及静脉给予血管活性药物治疗,对照组在常规治疗基础上予以心电监护,观察组在对照组基础上予以连续无创血流动力学监测,均治疗5d.对比两组治疗前及治疗12h时血流动力学指标,以及住院时间.结果:治疗12h,观察组心脏每搏输出量(SV)、平均动脉压(MAP)均高于对照组,心“,”Objective:To explore the guidance and efficacy of continuous non - invasive hemodynamic monitoring for the use of vasoactive a-gents in neonatal respiratory distress syndrome ( NRDS). Methods: 50 children with NRDS admitted to our hospital from January 2020 to July 2020 were divided into 2 groups with 25 cases in each group by random number table method. Both groups were treated with nasal continuous positive airway pressure ( NCPAP) and intravenously with vasoactive drugs. The control group was treated with electrocardiogram monitoring on the basis of conventional treatment, and the observation group was treated with continuous non - invasive hemodynamic monitoring on the basis of control group for 5 days. Hemodynamic indexes before treatment and at 12h of treatment and length of hospital stay were compared between the two groups. Results:After 12 hours of treatment, the stroke output ( SV) and mean arterial pressure ( MAP) of the observation group were higher than those of the control group , and the heart rate ( HR) was lower than that of the control group , with statistical significance ( P ＜ 0. 05 ). The hospitalization time of the observation group was shorter than that of the control group, and the difference was statistically significant ( P ＜ 0.05). Conclusion: Continuous non - invasive hemodynamic monitoring can improve the hemodynamic indexes and shorten the hospital stay in NRDS children during the treatment with vasoactive drugs.
