As for FHR, there was no significant difference between pre\u2010 and post\u2010epidural. The mean UtA\u2010PI (pulsatility index), UA\u2010PI, UA\u2010RI (resistance index), and UA\u2010S\/D (systolic\/diastolic ratio) were not significantly modified after EA. Nevertheless, MCA\u2010PI and RI significantly decreased in 15\u2009minutes after initiating EA compared with T0 values (<jats:italic>P<\/jats:italic> &lt; .05), and MCA\u2010PSV (resistance index and peak systolic velocities) was significantly increased compared with T0 at all times (<jats:italic>P<\/jats:italic> &lt; .05).
