Randomized Controlled Trial Multicenter Study
Thoracic paravertebral regional anesthesia improves analgesia after breast cancer surgery: a randomized controlled multicentre clinical trial.
The contribution of regional anesthesia with thoracic paravertebral blockade to postoperative analgesia remains unclear. We compared the effect of a combination of paravertebral blockade and propofol general anesthesia (GA) with sevoflurane GA and opioid analgesia on postoperative pain and opioid use for patients undergoing breast cancer surgery. ⋯ Our results were largely consistent with previous much smaller studies. Compared with sevoflurane GA with opioid analgesia, the combination of paravertebral analgesia with propofol GA provides an early clinical analgesic benefit in females having breast cancer surgery. This analysis is a substudy of an ongoing multicentre double-blinded randomized trial ( www.clinicaltrials.gov , NCT00418457) of cancer recurrence.

Randomized Controlled Trial Multicenter Study Clinical Trial
Transcutaneous auricular vagus nerve stimulation for pediatric epilepsy: study protocol for a randomized controlled trial.
Recently, clinical observations reported the potential benefit of vagus nerve stimulation (VNS) for pediatric epilepsy. Transcutaneous auricular vagus nerve stimulation (ta-VNS) is a newer non-invasive VNS, making it more accessible for treating pediatric epilepsy, yet there is limited clinical evidence for its effectiveness. ⋯ Results of this trial will help clarify whether ta-VNS treatment is beneficial for pediatric patients, and will make clear whether the anticonvulsive effect of ta-VNS is correlated with the improvement of sympathovagal imbalance.

Multicenter Study Comparative StudyUsing an International Clinical Registry of Regional Anesthesia to Identify Targets for Quality Improvement.
Despite the widespread use of regional anesthesia, limited information on clinical performance exists. Institutions, therefore, have little knowledge of how they are performing in regard to both safety and effectiveness. In this study, we demonstrate how a medical institution (or physician/physician group) may use data from a multicenter clinical registry of regional anesthesia to inform quality improvement strategies. ⋯ To our knowledge, this is the first large-scale effort to use a clinical registry to provide comparative outcome rates representing the safety and effectiveness of regional anesthesia. These results can be used to help inform quality improvement strategies.

Randomized Controlled Trial Multicenter Study
Effect of reversible intermittent intra-abdominal vagal nerve blockade on morbid obesity: the ReCharge randomized clinical trial.
Although conventional bariatric surgery results in weight loss, it does so with potential short-term and long-term morbidity. ⋯ Among patients with morbid obesity, the use of vagal nerve block therapy compared with a sham control device did not meet either of the prespecified coprimary efficacy objectives, although weight loss in the vagal block group was statistically greater than in the sham device group. The treatment was well tolerated, having met the primary safety objective.

Multicenter Study Observational StudyTransversus Abdominis Plane Block in Children: A Multicenter Safety Analysis of 1994 Cases from the PRAN (Pediatric Regional Anesthesia Network) Database.
Currently, there is not enough evidence to support the safety of the transversus abdominis plane (TAP) block when used to ameliorate postoperative pain in children. Safety concerns have been repeatedly mentioned as a major barrier to performing large randomized trials in children. The main objective of the current investigation was to determine the incidence of overall and specific complications resulting from the performance of the TAP block in children. In addition, we evaluated patterns of local anesthetic dosage selection in the same population. ⋯ The upper incidence of overall complications associated with the TAP block in children was 0.3%. More important, complications were very minor and did not require any additional interventions. In contrast, the large variability of local anesthetic dosage used can not only minimize potential analgesic benefits of the TAP block but also result in local anesthetic toxicity. Safety concerns should not be a major barrier to performing randomized trials to test the efficacy of the TAP block in children as long as appropriate local anesthetic dose regimens are selected.
