Paravertebral block via the surgical field versus epidural block for patients undergoing thoracotomy: a randomized clinical trial

Abstract

PVB may replace EP for postoperative pain control because of its technical simplicity and safety.

Noteworthy Literature in Regional Anesthesia 2013

“…VAS scores at 2, 24, and 48 hours for the epidural and paravertebral groups were 23 versus 26, 12 versus 10, and 12 versus 8. 4 Similar results were seen by Dango et al 5 in 80 patients receiving either thoracic epidural or a combination of paravertebral blockade/intrathecal opioid in his prospective, randomized, controlled trial. In this study, postoperative pain scores were statistically lower in the epidural group (3.4 vs 4.6 at rest and 4.4 vs 5.7 with movement) but the clinical courses were felt to be similar.…”

Myofascial Pain Syndrome in the Elderly and Self-Exercise: A Single-Blind, Randomized, Controlled Trial

“…The sample size for the noninferiority trial was calculated. 26 The noninferiority margin was set at 1.5 cm on a 10-cm visual analogue scale (VAS) 27 as the acceptable difference between SEIB and US. The type I error rate was set at 2.5%, with a desired power of 90%.…”

A prospective randomized trial of continuous paravertebral infusion versus intravenous patient-controlled analgesia after thoracoscopic lobectomy for lung cancer

“…In contrast, c-PVI of local anesthetics thorough a catheter below the parietal pleura has been known to reduce side effects of iv-PCA and effectively control postoperative pain (6). Although c-PVI could provide effective pain relief in comparison with iv-PCA with better side-effects profile in patients who underwent open thoracotomy (7)(8)(9)(10)(11), only a few existing studies have compared their analgesic effects after thoracoscopic lobectomy (6,12,13). Therefore, our study aimed to investigate the effectiveness of c-PVI as compared with that of iv-PCA after thoracoscopic lobectomy for lung cancer.…”
