Multicenter Study Observational StudyWaddell (Nonorganic) Signs and Their Association With Interventional Treatment Outcomes for Low Back Pain.
The rising use of injections to treat low back pain (LBP) has led to efforts to improve selection. Nonorganic (Waddell) signs have been shown to portend treatment failure for surgery and other therapies but have not been studied for minimally invasive interventions. ⋯ Whereas this study found no consistent relationship between Waddell signs and decreased mean pain scores, a significant relationship between the number of Waddell signs and treatment failure was observed.

Meta Analysis
Analgesic effects of erector spinae plane block for patients after breast surgery: a systematic review and meta-analysis.
This meta-analysis investigated the analgesic effects of erector spinae plane block (ESPB) in patients undergoing breast surgery. ⋯ ESPB significantly alleviated pain and reduced opioid consumption after breast surgery. Further research is needed to expand its clinical application.PROSPERO registration number CRD42020167900.

ReviewUltrasound-guided subparaneural popliteal sciatic nerve block: there is more to it than meets the eyes.
The popliteal sciatic nerve block is routinely used for anesthesia and analgesia during foot and ankle surgery. This article reviews our current understanding of the anatomy of the sciatic nerve and discusses how fascial tissue layers associated with the nerve may affect block outcomes. ⋯ The tibial and common peroneal nerves within the sciatic nerve trunk appear to be centrally separated by the Compton-Cruveilhier septum and encompassed by their own paraneural sheaths. This unique internal architecture of the sciatic nerve appears to promote proximal spread of local anesthetic to the internal aspect of the sciatic nerve trunk after a subparaneural injection at or below the divergence of the tibial and common peroneal nerves.

Randomized Controlled TrialUltrasound-Guided Pecto-Intercostal Fascial Block for Postoperative Pain Management in Cardiac Surgery: A Prospective, Randomized, Placebo-Controlled Trial.
To explore the effect of pecto-intercostal fascial plane block (PIFB) on postoperative opioid requirements, pain scores, lengths of intensive care unit and hospital stays and incidence of postoperative delirium in cardiac surgical patients. ⋯ Patients who received PIFB with bupivacaine showed a decline in cumulative opioid consumption postoperatively, but this difference between the groups was not statistically significant. Low incidence of complications and improvement in visual analog scale pain scores suggested that the PIFB can be performed safely in this population and warrants additional studies with a larger sample size.

Randomized Controlled Trial
Analgesic efficacy of the serratus anterior plane block in rib fractures pain: A randomized controlled trial.
Serratus anterior plane block (SAPB) was evaluated that in patients with the complaint of rib fracture pain in terms of total analgesic consumption and pain scores. ⋯ This study demonstrated that SAPB, as part of multimodal analgesia in pain management due to rib fractures, is safe and effective in reducing acute pain.
