Outcomes
Primary Outcome Measures
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".
Secondary Outcome Measures
The incidence of acute pain after chest surgery
An NRS score was performed 24 to 72 hours after surgery to determine the incidence of acute pain after thoracic 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".
Incidence of postoperative neuropathic pain
The incidence of neuropathic pain was measured by DN4 scale at the 3rd month after surgery.Douleur Neuropathique 4 (DN4) is a screening questionnaire to help identify neuropathic pain (NP) in clinical practice and research,where a DN4 scores greater than or equal to 4 represented the patients had "postoperative neuropathic pain".
Incidence of other postoperative complications
Postoperative complications included that pulmonary complications, delirium, intestinal obstruction, pulmonary embolism, acute respiratory failure, acute renal failure, incision infection, cerebrovascular accident and other complications related to surgery.
Incidence of readmission within 30 days after surgery
The incidence and the reason of readmission within 30 days after surgery was obtained through postoperative follow-up.
Incidence of death within 30 days after surgery
The incidence and the reason of death within 30 days after surgery was obtained through postoperative follow-up
Length of stay
The total length of hospital stay.
Cost of stay
The total cost of hospital stay.
icu length of stay
The number of hours of postoperative stay in ICU.
Incidence of secondary operation
Whether the patient has a second operation and the reason and the incidence of this operation.

5. Study Description
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.

Intervention Type
Procedure
Intervention Name(s)
Intercostal nerve block
Intervention Description
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.
