105 Non-Invasive Measurements of Hemodynamic Transition at Birth

Objective To investigate the hemodynamic changes during transition at birth obtaining non-invasive physiological data in healthy term infants. Methods In 18 newborns (GA 39 weeks (38–39)) born by a caesarian section; arterial oxygen saturation (SaO2) (preductally), heart rate (HR) and non-invasive b...

Description
Summary:Objective To investigate the hemodynamic changes during transition at birth obtaining non-invasive physiological data in healthy term infants. Methods In 18 newborns (GA 39 weeks (38–39)) born by a caesarian section; arterial oxygen saturation (SaO2) (preductally), heart rate (HR) and non-invasive blood pressure (BP) were measured and echocardiography using M-mode and Doppler flow was performed at 2, 5 and 10 minutes after birth. Results Oxygen saturation and HR were within recommended target ranges. Mean BP did not change between measurement intervals (55 mm Hg at 2 min, 54 mm Hg at 5 min. and 54 mm Hg at 10 min) and was similar as BP measured at day 1. Left ventricle output (LVO) significantly increased between 2 min and 5 min (120.3 mL/kg/min (35.1) vs. 167.4 mL/kg/min (67.3); p value
