Background: Labor epidural analgesia (LEA) effectively relieves labour pain, but it is still not available consistently for multiparous women in many institutions because of their obviously shortened labour length.
Methods: A total of 811 multiprous women were retrospective enrolled and firstly divided into two groups: LEA group or non-LEA group. And then they were divided into seven subgroups and analyzed according to the use of LEA and cervical dilation. The primary outcomes (time intervals, blood loss and Apgar scores) and secondary outcomes (maternal demographic characteristics and birth weight) were collected by checking electronic medical records.
