NCT05901441

Brief Summary

The purpose of this study is to compare the effects of three different doses of hydromorphone combined with ropivacaine and sufentanil combined with ropivacaine in epidural labor analgesia through prospective clinical trials, so as to explore whether hydromorphone combined with ropivacaine has advantages in epidural labor analgesia, and find out the optimal dose of hydromorphone. Participants will be randomly allocated to four groups: H1 group,H2 group,H3 group and SF group.For those in H1 group: they will be administered with15 ug/ml hydromorphone and 0.08% ropivacaine for epidural labor analgesia, For those in H2 group: they will be administered with17.5 ug/ml hydromorphone and 0.08% ropivacaine for epidural labor analgesia, For those in H3 group: they will be administered with 20 ug/ml hydromorphone and 0.08% ropivacaine for epidural labor analgesia, For those in SF group: they will be administered with 40 ug/ml sufentanil and 0.08% ropivacaine for epidural labor analgesia. The goal of this clinical trial is to provide a new treatment option for pregnant women in epidural labor analgesia, and to provide a basis for hydromorphone combined with ropivacaine in epidural labor analgesia.

Outcome Measures

Primary Outcomes (1)

  • Visual Analogue Scale(VAS)

    VAS will be monitored and recorded at 6 time points, including the time of entering the operating room(Time 0), when the first dose is given for 5 minutes(Time 1), when the first dose is given for 15 minutes(Time 2), when the first dose is given for 30 minutes(Time 3), 30 minutes after delivery (Time 4), and 60 minutes after delivery (Time 5). The VAS consists of a 10 cm line,with two end points representing 0 (no pain) and 10 (pain as bad as it could possibly be).

    30 minutes-1 hour

Secondary Outcomes (7)

  • Heart rate(HR)

    30 minutes-1.5 hours

  • Mean arterial pressure(MAP)

    30 minutes-1.5 hours

  • Pulse oxygen saturation

    30 minutes-1.5 hours

  • Duration of analgesia

    30 minutes-1.5 hours

  • The number of compressions

    30 minutes-1.5 hours

  • +2 more secondary outcomes
