Brief summary
Neuraxial analgesia is the gold standard to relieve labor pain. A recent Practice guidelines for obstetric anesthesia suggests that neuraxial analgesia should be provided in the early stage of labor (cervical dilation \< 5 cm) or on a individualized basis. The purpose of this randomized controlled trial is to investigate whether neuraxial labor analgesia administered on an individualized basis can improve analgesia quality and maternal satisfaction.
Detailed description
Neuraxial analgesia is the gold standard to relieve labor pain. It also helps to attenuate maternal anxiety and improve maternal satisfaction. A recent Practice guidelines for obstetric anesthesia suggests that neuraxial analgesia should be provided in the early stage of labor (cervical dilation \< 5 cm) or, for some special patients, be provided on a individualized basis. Studies showed that, when compared with late administration, early administration of labor analgesia resulted in equivocal findings for spontaneous, instrumented, and cesarean delivery. The investigators hypothesize that neuraxial labor analgesia provided on an individualized basis will further improve analgesia quality and maternal satisfaction. The purpose of this randomized controlled trial is to investigate whether neuraxial labor analgesia administered on an individualized basis can improve analgesia quality and maternal satisfaction.
Interventions
Epidural analgesia will begin when asked by the parturients (during the first stage of labor) and the numeric rating scale is 5 or higher. Analgesia will be terminated at the end of the third stage of labor.
Epidural analgesia will begin when asked by the parturients (during the first stage of labor) and the cervix is dilated to 1 cm or more. Analgesia will be terminated at the end of the third stage of labor.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The most severe labor pain score during labor | Assessed at 24 hours after delivery | Assessed with numeric rating scale, where 0 indicates no pain and 10 the worst pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Cesarean delivery | At the time of delivery | Incidence of Cesarean delivery |
| Neonatal Apgar score | At 1 and 5 minutes after delivery | Neonatal Apgar score |
| Maternal satisfaction with labor analgesia | Assessed at 24 hours after delivery | Assessed with the Likert scale, where 1=extremely dissatisfaction, 2=dissatisfaction, 3=neither dissatisfaction nor satisfaction, 4=satisfaction, 5=extremely satisfaction. |
| Incidence of instrumental delivery | At the time of delivery | Incidence of instrumental delivery |
| Rate of breast-feeding | At 24 hours and 42 days after delivery | Rate of breast-feeding |
| Incidence of postpartum depression | At 42 days after delivery | Postpartum depression will be diagnosed as Edinburgh postnatal depression scale of 10 or higher. |
| Persistent pain score at 24 hours and 42 days after delivery | At 24 hours and 42 days after delivery | Assessed with numeric rating scale, where 0 indicates no pain and 10 the worst pain. |
