Although the erector spinae plane block has been used in various truncal surgical procedures, its clinical benefits in patients undergoing spinal surgery remain controversial. The aim of this meta-analysis was to evaluate the clinical benefits of erector spinae plane block in patients undergoing spinal surgery. ⋯ Erector spinae plane block improves analgesic efficacy among patients undergoing spinal surgery compared with nonblocked controls; however, there is insufficient evidence regarding the benefits of erector spinae plane block for rapid recovery.

The study investigated virtual reality (VR) immersion in alleviating procedure-related pain in patients with chronic pain undergoing fluoroscopy-guided minimally-invasive intervention in a prone position at an outpatient clinic. ⋯ VR immersion can be safely used as a novel adjunct to reduce procedural pain and anxiety during fluoroscopic pain intervention.

Various truncal block techniques with ultrasonography (USG) are becoming widespread to reduce postoperative pain and opioid requirements in video-assisted thoracoscopic surgery (VATS). The primary aim of our study was to determine whether the USG-guided serratus anterior plane block (SAPB) is as effective as the thoracic paravertebral block (TPVB) in VATS. Our secondary aim was to evaluate patient and surgeon satisfaction, block application time, first analgesic time, and length of hospital stay. ⋯ An SAPB that is applied safely and rapidly as a part of multimodal analgesia in patients who undergo VATS is not inferior to the TPVB and can be an alternative to it.

The quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. ⋯ No significant association was found between the quality of SGAs and the studies' characteristics. The quality of the SGAs performed in chronic pain trials was poor. To enhance the quality of SGAs, scholars should consider the developed criteria when designing and conducting trials, particularly those which need to be specified a priori .

The thoracic paravertebral block is an effective analgesic technique for postoperative pain management after breast surgery. The ultrasound-guided retrolaminar block (RLB) is a safer alternative to conventional paravertebral block. Thus, we assessed the analgesic efficacy of ultrasound-guided RLB for postoperative pain management after breast surgery. ⋯ A single injection of ultrasound-guided RLB did not reduce postoperative analgesic requirements following breast surgery.
