Effect of Perioperative Dexmedetomidine on Chronic Post-Surgical Pain

The goal of this clinical trial is to learn if intranasal dexmedetomidine works to improve sleep quality to treat chronic post-surgical pain (CPSP) in patients undergoing thoracic surgery. It will also learn about the safety of intranasal dexmedetomidine.this clinical trial could include any of the following: Adults aged 18-80 years, Elective surgical patients scheduled for their first thoracoscopic lung resectiony, ASA physical status I-III, and sign the informed consent form. The main questions it aims to answer are: Does intranasal dexmedetomidine reduce the incidence of CPSP in patients undergoing elective thoracic surgery? Does perioperative sleep quality mediates the effect of intranasal dexmedetomidine in improving CPSP outcomes at 3 months post-surgery? What are the safety concerns or medical complications that participants may experience when using intranasal dexmedetomidine perioperatively? Researchers will compare the intervention group receiving intranasal dexmedetomidine to a placebo (a look-alike substance that contains no drug) to assess its impact on perioperative sleep quality and the reduction in CPSP incidence at 3 months post-surgery. Participants will: Take the study drug (intranasal dexmedetomidine) or a placebo (saline) every night between 9:00-9:30 PM, starting the day before surgery and continuing until the day before discharge. After the drug administration, undergo 3 hours of continuous monitoring with ECG and wear a wearable device for ongoing assessment. Cooperate with researchers to assess sedation, pain, sleep, emotional status, medication usage, adverse events, and postoperative recovery quality on postoperative days 1, 2, and 3 You will be contacted by phone at 1, 3, and 6 months by the research team to inquire about sleep, pain, medication use, and overall quality of life after discharge.

Effect of Perioperative Sleep Quality on Chronic Post-Surgical Pain

The goal of this prospective observational cohort study is to assess the impact of perioperative sleep quality on the development of chronic post-surgical pain (CPSP) in adult patients (aged 18-80 years, ASA I-III) undergoing elective video-assisted thoracic surgery (VATS), modified radical mastectomy (MRM), or coronary artery bypass grafting (CABG). The main questions it aims to answer are: Does poor perioperative sleep quality increase the risk of CPSP at 3 months post-surgery? How do subjective and objective sleep parameters (e.g., total sleep duration, deep sleep time) correlate with CPSP and recovery outcomes? Researchers will compare patients with varying perioperative sleep quality levels (assessed via the Richards-Campbell Sleep Questionnaire \[RCSQ\] and wearable device data) to evaluate differences in CPSP incidence, pain and quality of life. Participants will: Wear a Huawei wearable device to collect objective sleep data (e.g., sleep duration, deep sleep time) during hospitalization. Complete questionnaires preoperatively and postoperatively, including RCSQ, Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale (HADS), and Brief Pain Inventory (BPI). Undergo follow-up assessments at 1, 3, and 6 months post-surgery to evaluate pain scores , CPSP status, and quality of life (SF-36).
