A Comparative Effect of Echogenic Needle for Nerve Block on Acute and Chronic Postoperative Pain
The Second Affiliated Hospital of Chongqing Medical University
1,000 participants
Jun 12, 2023
INTERVENTIONAL
Conditions
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.

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.
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.
