Comparison of different adjuvant analgesia for paravertebral block in video-assisted thoracoscopic surgery: A double-blind randomized controlled trial.

ABSTRACT:

Background

Local anaesthetic adjuvants have been shown to provide better pain relief and extend the duration of analgesia. But little information is available on which adjuvants are more effective in block extension for thoracic paravertebral block (TPVB) during video-assisted thoracoscopic surgery (VATS). This study aimed to compare the analgesic efficacies of different adjuvants with 0.375% ropivacaine in ultrasound-guided TPVB for VATS.

Methods

A total of 120 patients who underwent VATS at the study hospital in 2022-2023 were recruited and randomly divided into four groups, including the control group (Group R), which received 20 ml ropivacaine 0.375% for TPVB, and the intervention groups: Group D (0.375% ropivacaine with 1 µg/kg dexmedetomidine in a total of 20 ml for TP
