NCT06815744

Brief Summary

The study subjects consisted of patients who underwent elective total knee arthroplasty (TKA) at Gansu Provincial Hospital of TCM from November 2023 to January 2024. The Pittsburgh Sleep Quality Index Questionnaire (PSQI) was used to assess the overall sleep status of patients over the past month. All patients were divided into normal sleep group (PSQI ≤ 5) and poor sleep group (PSQI score \> 5). Postoperative pain was assessed using a numeric rating scale (NRS), and hydromorphone (HM) consumption, number of rescue analgesia, and quality of recovery QoR-15 scores were recorded 24 hours after surgery. Spearman correlation analysis was used to detect the correlation between each index and preoperative PSQI score. A logistic regression model was used to analyze the relationship between PSQI score, serum BDNF and CB1R concentrations, and the occurrence of moderate to severe pain 24 hours after surgery. Generalized linear regression models combined with restricted cubic spline models were used to analyze the relationship and dose-response relationship between PSQI, BDNF, and CB1R and QoR-15 score and HM consumption at 24 hours after surgery after adjusting for confounders. Serum BDNF and CB1R mediation effects were analyzed by Process plug-in.

Outcome Measures

Primary Outcomes (1)

  • postoperative pain score

    The numerical rating scale (NRS) was used to evaluate the level of postoperative pain in patients. NRS scores were recorded at 2h, 6h, 12h, 24h, and 48h postoperatively, and the incidence of moderate to severe pain at corresponding time points was calculated. On this scale, 0 represents no pain, while 10 represents the worst imaginable pain. Based on the NRS scores, patients were classified into three pain categories: no pain (0), mild pain (1-3/10), and moderate to severe pain (≥4/10)

Biospecimen

Retention: SAMPLES WITHOUT DNA

Before anesthesia, 3 ml of venous blood was collected from the non-infusion side of the patient (on an empty stomach). The whole blood was collected into a blood collection tube containing EDTA sodium salt. After standing at room temperature for 30 minutes, the blood was centrifuged at 3000 rpm for 10 minutes. The supernatant was then placed in a cryopreservation box and stored at -80℃ until use.
