NCT06281431

Brief Summary

Surgical pain is a common complication after surgery, affecting patient recovery and treatment quality. \>20% of patients suffer from chronic postoperative pain. China has \>70 million surgeries yearly. Nerve block manages postoperative pain, with developing nerve block needles now used in clinics. Developed needles may have better pain management effects than non-developed ones, but their effect on reducing chronic pain remains unclear. This study aims to explore the effect of developed nerve block needles on postoperative pain and compare them to non-developed needles, providing new ideas and methods for pain management.

Outcome Measures

Primary Outcomes (2)

  • Chronic postoperative pain

    Incidence of Chronic pain assessment from 3 months after surgery

    The third month after surgery.

  • Moderate to severe pain

    Pain intensity (assessed by number rating scale, 0 represents no pain, 10 represents intolerable pain) more than 4

    from end of surgery to 24 hours after surgery.

Secondary Outcomes (5)

  • Acute postoperative pain

    From the ending of surgery to leaving the postanesthesia care unit, an average of 30 minutes

  • Acute postoperative pain

    From return to the ward to 12 hours after return to the ward

  • Acute postoperative pain

    From 12 hours after return to the ward to 24 hours after return to the ward

  • Puncture operation time

    From the ending of surgery to leaving the postanesthesia care unit, an average of 30 minutes

  • Number of needle passes

    From the ending of surgery to leaving the postanesthesia care unit, an average of 30 minutes

Study Arms (2)

Echogenic nerve block needle

EXPERIMENTAL

Using a echogenic nerve block needle.

Procedure: Echogenic nerve block needle

Non-echogenic nerve block needle

OTHER

Using a common nerve block needle.

Procedure: Non-echogenic nerve block needle

Interventions

A 22G 8-cm echogenic nerve block needle (LEAPMED, CHINA) is selected for the procedure, administered under ultrasound guidance. Subsequently, a volume of 20 ml 0.375% ropivacaine is injected at the needle's tip for analgesic effect. The spread of the medication will be assessed through short- and long-axis imaging perspectives. Following this, evaluations are conducted to assess acute postoperative pain as well as chronic postoperative pain. Parameters such as the duration of nerve blockade, the incidence of punctures, and any associated complications are all meticulously appraised.

Echogenic nerve block needle

A 22G 8-cm thin wall low bottom nerve block needle (KDL, CHINA) is selected for the procedure, administered under ultrasound guidance. Subsequently, a volume of 20 ml 0.375% ropivacaine is injected at the needle's tip for analgesic effect. The distribution of the medication will be assessed using short- and long-axis imaging perspectives. Following this, evaluations are conducted to assess acute postoperative pain as well as chronic postoperative pain. Parameters such as the duration of nerve blockade, the number of punctures, and any associated complications are all meticulously appraised.
