title: Maternal hemodynamic influence on uteroplacental oxygen distribution during cesarean section.
abstract: This study investigated maternal hemodynamic influence on uteroplacental oxygen distribution and neonatal outcome during cesarean section (CS). CS was performed on 80 parturients using two anaesthetic techniques: spinal anaesthesia (SA) and general balanced anaesthesia (GBA). Indications for CS were exclusively obstetric related. Monitored maternal parameters were: ECG, heart rate (HR), non-invasive blood pressure (NIBP), saturation (SaO2). Gas parameters in umbilical artery, vein, and neonatal capillary blood were sampled. Vitality was assessed by the Apgar scoring, first breath-taking time and the first breastfeeding attempt. Hypotension was the most common finding after SA induction. GBA group presented changes such as QT inversion (12.5%), tachycardia (55%), and bradycardia (2.5%). SA group experienced higher rates of sinus tachycardia (45%) and ventricular dysrhythmias (2.5%). Neonatal oxygenation was significantly higher in SA group. Higher quality of early neonatal adaptation in the SA group confirms it as the technique with the least neonatal risk during CS.
