Review Meta Analysis
Efficacy of erector spinae plane block for analgesia in breast surgery: a systematic review and meta-analysis.
The erector spinae plane block has similar efficacy to paravertebral block for reducing post breast surgery pain, but is inferior to pectoralis nerve block.

Review Meta Analysis
Bilateral Erector Spinae Plane Block for Postoperative Analgesia in Laparoscopic Cholecystectomy: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
Erector spinae plane (ESP) block is a novel regional anesthetic technique. Its application for postoperative analgesia has been increasing since 2016; however, its effectiveness remains uncertain and varies according to the type of surgery. This meta-analysis aimed to assess the analgesic efficacy of ESP block in patients undergoing laparoscopic cholecystectomy. ⋯ This meta-analysis showed that bilateral ultrasound-guided ESP block could be considered as an effective option to reduce opioid consumption and the time to first rescue analgesic and seems to be also a safe technique in adults undergoing laparoscopic cholecystectomy.

Review Meta AnalysisParavertebral block for the prevention of chronic postsurgical pain after breast cancer surgery.
Patients frequently report chronic postsurgical pain (CPSP) after breast cancer surgery (BCS). The paravertebral block (PVB) is an effective technique to reduce acute postoperative pain after BCS, but its efficacy in preventing CPSP is unclear. This meta-analysis evaluates the efficacy of PVB in preventing CPSP after BCS. ⋯ Similar results were obtained at 3 and 12 months (RR 0.78 (95% CI 0.57 to 1.06), RR 0.45 (95% CI 0.14 to 1.41), respectively). Data for the 12-month time point from seven studies (2087 patients) were analyzed and showed that PVB protected against CPSNP, with low quality of evidence (RR 0.51 (95% CI 0.31 to 0.85)). In conclusion, CPSP was not found significantly prevented by PVB after BCS despite the limits in the included studies; nevertheless, PVB could prevent CPSNP by impacting the transition from acute to chronic pain.

Meta AnalysisTransversus abdominis plane block versus thoracic epidural analgesia in colorectal surgery: a systematic review and meta-analysis.
The efficacy of transversus abdominis plane (TAP) block compared with thoracic epidural analgesia (TEA) in abdominal surgery has been controversial. We conducted this systematic review and meta-analysis to assess outcomes of TAP block and TEA in a procedure-specific manner in colorectal surgery. ⋯ Perhaps more germane to minimally invasive procedures, TAP block is equivalent to TEA in terms of postoperative pain control and provides better functional recovery with lower incidence of adverse events in patients undergoing colorectal surgery.

The erector spinae plane (ESP) block is an emerging regional anesthetic technique with significant potential for clinical benefit. Nevertheless, its exact mechanism(s) of action has been much debated. We reviewed the available literature to explore the possible mechanisms of analgesia for the ESP block. ⋯ A systemic effect of local anesthetic is also plausible, but unlikely to be a major contributor to clinical analgesic efficacy. The evidence for significant analgesia due to other proposed mechanisms, such as fascia-mediated analgesia or lymphatic spread, are currently limited and thus remain speculative. Understanding the mechanisms of action could assist clinicians in further investigating and refining ESP block performance, with the ultimate goal of optimizing analgesic efficacy and improving postoperative patient outcomes.
