NCT06602440

Brief Summary

The purpose of this study is to observe the appropriate indwelling depth of epidural catheter when labor analgesia is performed in the mode of DPE combined with PIEB, and then shorten the onset time of labor analgesia and reduce the occurrence of catheter-related adverse outcomes.

Outcome Measures

Primary Outcomes (2)

  • Time of satisfactory analgesia.

    The time when the NRS score is less than 3 after the first administration during labor analgesia with DPE combined with PIEB mode.

    First dose in the epidural space to NRS score being less than 3.

  • Consumption of ropivacaine per unit time.

    The consumption of ropivacaine per unit time during the entire labor analgesia process.

    First dose in the epidural space to the end of the third stage of labor.

Secondary Outcomes (4)

  • Related adverse outcomes.

    First dose in the epidural space to the end of the third stage of labor.

  • Anesthesia level and lower limb motor block.

    When labor analgesia is satisfactory.

  • Duration of labor.

    From the onset of labor to its end.

  • Changes in fetal heart rate and uterine contraction pressure.

    Before and after labor pain.

Study Arms (3)

3cm group

OTHER

When performing Dural Puncture Epidural technique with Programmed Intermittent Epidural Bolus(PIEB) mode for labor analgesia, the indwelling depth of the epidural catheter is 3 centimeters.

Procedure: The indwelling length of epidural catheter is 3 centimeters.

5cm group

OTHER

When performing Dural Puncture Epidural technique with Programmed Intermittent Epidural Bolus(PIEB) mode for labor analgesia, the indwelling depth of the epidural catheter is 5 centimeters.

Procedure: The indwelling length of epidural catheter is 5 centimeters.

7cm group

OTHER

When performing Dural Puncture Epidural technique with Programmed Intermittent Epidural Bolus(PIEB) mode for labor analgesia, the indwelling depth of the epidural catheter is 7 centimeters.

Procedure: The indwelling length of epidural catheter is 7 centimeters.

Interventions

When performing Dural Puncture Epidural technique with Programmed Intermittent Epidural Bolus(PIEB) mode for labor analgesia, According to different indwelling lengths of epidural catheters as variables, patients are divided into three treatment groups(3cm group 、5cm group and 7cm group)
