Brief Summary:
Parturients who need combined spinal-epidural analgesia for labour analgesia are randomly assigned to two groups. For the handheld ultrasound-assisted technique group, ultrasound with 3D navigation function is used to determine the needle insertion point and the insertion angle. For the conventional palpation-guided technique group, the interspinous space is detected by palpation. Procedure time, the number of needle passes, the number of needle insertion attempts, success rate, and complications are compared.

Condition or disease Intervention/treatment Phase
Labor Analgesia Device: handheld ultrasound-assisted technique Other: conventional palpation-guided technique Not Applicable

Detailed Description:
This study aims to determine whether handheld ultrasound-guidance can reduce procedural time for labor combined spinal-epidural analgesia compared with conventional surface landmark-guided technique.

  12. Procedural discomfort using 11-point verbal rating scale [ Time Frame: During procedure ]
    Degree of discomfort during the procedure using 11-point verbal rating scale (0=no discomfort, 10=most discomfort imaginable)

  13. Depth by ultrasound [ Time Frame: During procedure ]
    Depth to the ligamentum flavum-dura mater complex (LFD) as determined by ultrasound

  14. Actual needle depth (cm) [ Time Frame: During procedure ]
    Depth of the needle when the epidural space and dural space are found (cm)

  15. Failure of labor analgesia [ Time Frame: Within 2 hours after the procedure ]
    The need to reinsert a new epidural catheter due to lack of sufficient analgesia within 2 hours of the primary insertion

  16. Patient satisfaction using 11-point verbal rating scale [ Time Frame: From the end of the procedure to delivery ]
    Patient satisfaction with the quality of labor analgesia using 11-point verbal rating scale (0=very unsatisfied, 10=very satisfied)
