Clinical Trial Summary

Prospective, randomized, and controlled trial to compare the postoperative pain management of paravertebral nerve block with liposomal bupivacaine to ropivacaine in patients undergoing elective thoracoscopic surgery.

Description:

The objective of this study is to validate the analgesic efficacy of liposomal bupivacaine (LB) compared with ropivacaine when injected for paravertebral nerve block (PVB) for video-assisted thoracoscopic surgery (VATS).

We hypothesize that LB will be superior to ropivacaine in terms of postoperative pain control following VATS. The primary outcome of this study will be NRS pain scores for resting pain and NRS pain scores for cough pain 24 hours following surgery. Secondary outcomes will include pain scores over the first 120 hours following surgery, opioid consumption, opioid-related adverse events, block-related adverse events, time of first getting out of bed, catheter indwelling time, postoperative hospitalization time, patient satisfaction, and chronic pain at 1, 3, and 6 months after surgery.

Secondary	Hospital Anxiety and Depression Scale, HADS	The Hospital Anxiety and Depression Scale (HADS) is primarily used to screen for anxiety and depression in general hospital patients.

The impact of insomnia on daily functioning, the subject's awareness of the impact of insomnia on themselves, and the level of depression caused by sleep disorders.	day1 before surgery
