NCT04217213

Brief Summary

This project intends to investigate the effects of intercostal nerve block with ropivacaine combined with mecobalamin on chronic post-surgical pain (CPSP) in thoracic postoperative patients. Related clinical characteristics of postoperative chronic pain. The results of the study provide clinicians with a simple and inexpensive new method of preventing CPSP, in order to prevent the occurrence of CPSP and reduce the incidence of CPSP, thereby reducing CPSP to patients and their families, hospitals. And public resources.

Outcome Measures

Primary Outcomes (1)

  • Incidence of chronic pain after chest surgery

    The incidence of chronic pain after chest surgery was measured by NRS(numeric rating scales) at the 3rd month after surgery.For pain evaluation,we used the 11 point numeric rating scale(NRS),where an NRS scores of 0 represented "no pain" and a score of 10 represented "worst pain imaginable".

    At the 3rd month after surgery

Secondary Outcomes (9)

  • The incidence of acute pain after chest surgery

    24 to 72 hours after surgery

  • Incidence of postoperative neuropathic pain

    At the 3rd month after surgery

  • Incidence of other postoperative complications

    At the 3rd month after surgery

  • Incidence of readmission within 30 days after surgery

    At the 30 days after surgery

  • Incidence of death within 30 days after surgery

    At the 30 days after surgery

  • +4 more secondary outcomes

Study Arms (2)

ropivacaine combined with mecobalamine

EXPERIMENTAL

Intercostal nerve block with 0.5% ropivacaine combined with mecobalamine (0.5mg).

Procedure: Intercostal nerve block

ropivacaine

ACTIVE COMPARATOR

Intercostal nerve block with 0.5% ropivacaine alone.

Procedure: Intercostal nerve block

Interventions

In the experimental group, the surgeons used 0.5% ropivacaine combined with mecobalamine (0.5mg) before the operation to perform intercostal nerve block in the operating incision, closed thoracic drainage incision and one intercostal nerve block in each upper and lower costal cavity, and injected 5ml in each intercostal nerve block.In the control group, surgeons used 0.5% ropivacaine alone before the operation to perform intercostal nerve block through the operating incision, closed thoracic drainage incision and one intercostal nerve block in each upper and lower costal cavity. 5ml was injected into each intercostal nerve block.
