From the abstract
Thoracoscopy-guided thoracic paravertebral block (TG-TPVB) is a new analgesia technique; however, the duration of a single TG-TPVB is short. Esketamine combined with local anesthetics can prolong the duration of nerve block.
Reported results
The time to first PCIA demand in the three esketamine groups were longer than in the control group. However, S2 and S3 groups were longer than S1 group. NRS pain scores in the three esketamine groups were lower than in the control group at 6, 12, 24, and 48 h postoperatively.
Authors' conclusions
Esketamine combined with ropivacaine for TG-TPVB prolonged postoperative analgesia, reduce pain scores, reduced analgesic consumption, and facilitated recovery. Esketamine at 0.2 mg/kg seems to show a good balance effect in many aspects.
