We conducted a prospective, observational study to investigate the relationship between the respiratory variation in aortic blood flow peak velocity (ΔVPeak) measured by echocardiography in the proximal ascending aorta from the suprasternal notch window and the ΔVPeak measured at the level of the aortic annulus from the classical apical five-chamber view. We studied children aged from 1 to 10 years referred for surgery under general anesthesia with positive pressure ventilation, after induction of general anesthesia. Twenty-two children (mean age = 5 ± 3 years) were recruited. There was a significant relationship between the ΔVPeak recorded via the suprasternal notch view and the ΔVPeak recorded via the apical five-chamber view (r = 0.62 [95% confidence interval 0.25-0.84], P = 0.003). The ΔVPeak measured using the suprasternal notch route could be considered to predict fluid responsiveness in children under mechanical ventilation, notably when the access to the chest wall is limited during surgery.
我们进行了一项前瞻性观察性研究，以探讨通过胸骨上切迹窗在升主动脉近端用超声心动图测量的主动脉血流峰值速度呼吸变异（ΔVPeak）与通过经典心尖五腔视图在主动脉瓣环水平测量的ΔVPeak之间的关系。我们研究了1至10岁在全身麻醉诱导后接受正压通气下手术的儿童。招募了22名儿童（平均年龄 = 5 ± 3岁）。通过胸骨上切迹视图记录的ΔVPeak与通过心尖五腔视图记录的ΔVPeak之间存在显著关系（r = 0.62 [95%置信区间0.25 - 0.84]，P = 0.003）。使用胸骨上切迹途径测量的ΔVPeak可被认为能预测机械通气下儿童的液体反应性，尤其是在手术期间胸壁入路受限的情况下。
