ABSTRACT
BACKGROUND: Some surgeons have adopted the use of video-assisted thoracoscopic surgery (VATS) or robotic surgery to perform resections for lung cancer. VATS is associated with less pain and a decrease in pulmonary complications compared with open thoracotomies. Long-acting liposomal bupivacaine (LB) intercostal nerve blocks are reported to provide superior pain relief compared with epidural catheters in the first 3 d after a thoracotomy. This study examined whether LB improves pain after VATS and if it provides effective analgesia after a thoracotomy. MATERIALS AND METHODS: A retrospective review was performed on 151 consecutive patients undergoing a VATS or thoracotomy who received paravertebral nerve blocks. VATS patients received paravertebral nerve blocks with LB (VATS-LB) or 0.25% bupivacaine with epinephrine (BE; VATS-BE). Thoracotomy patients received paravertebral nerve blocks via LB injections. Pain scores, narcotic utilization, complications, and hospital length of stay were examined. RESULTS: Fifty patients underwent a VATS-LB, 53 underwent a VATS-BE, and 32 underwent a thoracotomy. Thoracotomy and VATS-LB patients had pain scores lower than VATS-BE patients in the first 48 h after surgery (P < 0.004). Opioid use was not significantly different between the thoracotomy and VATS-LB patients throughout the first 2 wk postoperatively. CONCLUSIONS: LB paravertebral blocks significantly improve postoperative pain in comparison with 0.25% BE blocks in VATS patients. LB paravertebral blocks also provide effective analgesia in patients undergoing thoracotomies.
