Effect of Epidural Catheter Retention Depth on Labor Analgesia Performed in DPE Combined With PIEB Model

Observations on the Effect of Different Depths of Epidural Catheter Retention on the DPE Technique Combined With the PIEB Mode of Labor Analgesia：a Single-center, Prospective, Randomized Controlled Study

Sponsor

General Hospital of Ningxia Medical University

Enrollment

102 participants

Start Date

Jul 1, 2024

Study Type

INTERVENTIONAL

Conditions

Labor Analgesia

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.

Interventions

PROCEDUREThe indwelling length of epidural catheter is 3 centimeters.

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）

PROCEDUREThe indwelling length of epidural catheter is 5 centimeters.

PROCEDUREThe indwelling length of epidural catheter is 7 centimeters.
