Overview
Brief Summary
This research group plans to design a prospective, double-blind, randomized controlled study to explore the effect of taVNS on hs-cTnT in elderly patients undergoing thoracoscopic surgery, and to evaluate the effect on perioperative myocardial injury and postoperative analgesia during thoracoscopic surgery.
Detailed Description
A small number of studies based on transcutaneous auricular vagus nerve stimulation have shown that it has good therapeutic effects on patients with cardiovascular disease, and is simple to operate, with few complications and low risks. However, thoracic surgery is closer to the heart and has a higher incidence of perioperative myocardial injury. , and hs-cTnT has become a biomarker that predicts myocardial injury. This research group plans to design a prospective, double-blind, randomized controlled study to explore the effect of taVNS on hs-cTnT in elderly patients undergoing thoracoscopic surgery, and to evaluate the effect on perioperative myocardial injury and postoperative analgesia during thoracoscopic surgery.

- •ASA score of Ⅰ-Ⅲ
- •Able to communicate with the researcher Communicate and cooperate with patients completing assessment scales.
Exclusion Criteria
- •Patients with congenital heart disease, coronary heart disease, myocardial infarction, severe heart block or implanted cardiac pacemaker
- •Patients with neurological diseases such as cerebral infarction, cerebral hemorrhage or stroke
- •Patients with pain, damage, infection or unhealed ear trauma in the area near the external auricle

Outcomes
Primary Outcomes
high-sensitivity troponin T
Time Frame: The first day after surgery
Trained researchers will draw 3-5ml blood samples before surgery, on the first day after surgery, and on the third day after surgery and store them in vacuum blood collection tubes containing lithium heparin. They will be temporarily stored in a refrigerator at 2-8°C within 24 hours. Sent to laboratory for analysis. All blood samples were analyzed by staff who received professional training in detecting Hs-cTnT using the Roche cobas e411 electrochemiluminescence fully automatic immunoassay analyzer.
Secondary Outcomes
- Myocardial injury after surgery(30 days after surgery)
- high-sensitivity troponin T(the third day after surgery)
- NRS score 24 hours after surgery.(The three day after surgery)
