Registration Number
NCT06569953
Lead Sponsor
The Second Affiliated Hospital of Chongqing Medical University
Brief Summary

The goal of this clinical trial is to evaluate the efficacy and safety of liposomal Bupivacaine administered by paravertebral block for the treatment of acute and chronic pain after video-assisted thoracoscopic lobectomy.

Detailed Description

Researchers will compare liposomal bupivacaine to bupivacaine to see if liposomal bupivacaine works better to treat acute and chronic pain after video-assisted thoracoscopic lobectomy.Participants will:1.Received liposomal bupivacaine or bupivacaine paravertebral block before surgery. 2.Keep a diary of their pain scores within 30min after recovery from anesthesia and 6h, 12h, 24h, 48h, 72h and 90d after the beginning of injection of experimental drugs.

Movement-evoked pain score30 minutes after recovery from anesthesia,6 hours, 12hours, 24hours , 48hours and 72 hours after the intervention

Use pain Numeric Rating Scale(NRS) to evaluate the movement-evoked pain score at 30minutes after recovery from anesthesia and at 6 hours, 12hours, 24hours , 48hours and 72 hours after the intervention.(NRS scale 0-10, where 0 was no pain, and 10 was the worst possible pain)

Proportion of participants who did not use rescue analgesiafrom 0-72 hours after the intervention

Proportion of participants who did not use rescue analgesia during 0-12 hours, 12-24 hours, 24-48 hours, 48-72 hours and 0-72 hours after the intervention.

Score of satisfaction with analgesiaAt 72 hours after the intervention

At 72 hours after the intervention,the participants rated the satisfaction with analgesia.Satisfaction rating scale 0-5,where 0 was poor drug effectiveness, and 5 was excellent drug efficacy)

The cumulative dosage of rescue analgesiafrom 0-72 hours after the intervention

The cumulative dosage of rescue analgesia during 0-12 hours, 12-24 hours, 24-48 hours, 48-72hours and 0-72hours after the intervention.

Length of hospital stayFrom date of surgery until the date of first hospital discharge,assessed up to 1 months

Duration of participants from hospital admission to hospital discharge

Chronic pain scorepostoperative day (POD) 90
