What this Trial Is About
Surgical pain after operations is a common problem that can affect recovery and treatment quality. Over 20% of patients experience chronic pain following surgery. In China, more than 70 million surgeries occur annually. This trial investigates the effects of a newly developed nerve block needle compared to a standard nerve block needle on managing both acute and chronic postoperative pain, aiming to find better methods for pain relief after surgery. The study compares two types of nerve block needles used under ultrasound guidance: an echogenic needle and a non-echogenic needle. Both procedures involve injecting 20 ml of 0.375% ropivacaine at the needle tip to help control pain. Researchers will evaluate the spread of medication, the duration of nerve blockade, the number of needle punctures, and any related complications. Participants will be randomly assigned to one of these needle groups. Participants will be monitored for acute pain immediately after surgery and up to 24 hours afterward, as well as chronic pain three months post-surgery. Additional assessments include measuring puncture operation time and tracking any complications. The study duration includes time from surgery through follow-up visits at specified intervals. All evaluations aim to understand how these needles impact pain management and patient recovery.
