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.

Randomized Controlled TrialFemoral artery block (FAB) attenuates thigh tourniquet-induced hypertension: a prospective randomized, double-blind, placebo-controlled trial.
Prolonged tourniquet inflation during surgery frequently leads to tourniquet hypertension (TH), which is thought to arise from compression of A-δ fibers leading to sympathetically mediated C fiber activation. In the lower extremity, C fibers and other sympathetic nerve fibers are carried along the femoral artery. We hypothesized that blockade of these fibers at the femoral artery would decrease the incidence of TH. ⋯ Under these experimental conditions, injection of local anesthetic around the femoral artery reduced the incidence of TH and intraoperative esmolol requirement.

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 Trial
Changes of Opioid Consumption After Lumbar Fusion Using Ultrasound-Guided Lumbar Erector Spinae Plane Block: A Randomized Controlled Trial.
The erector spinae plane block (ESPB) is gaining popularity in lumbar fusion for postoperative pain management. ⋯ Ultrasound-guided lumbar ESPB reduces the amount of analgesics required during and after lumbar fusion and reduces the postoperative Visual Analog Scale pain score.
