Local and regional anesthesia

A mesenteric traction syndrome (MTS) is elicited by prostacyclin (PGI2)-induced vasodilation and identified by facial flushing, tachycardia, and hypotension during abdominal surgery. We evaluated whether thoracic epidural anesthesia (TEA) influences the incidence of MTS. ⋯ The incidence of MTS is not prevented by TEA in patients undergoing open esophagectomy. On the contrary, the risk of hypotension is increased in patients exposed to TEA during surgery, and the results suggest that it is advantageous to delay activation of TEA. Also, MTS seems to be associated with a systemic inflammatory response, maybe explaining the aggravated post-operative outcome.

This study aimed to investigate the analgesic efficacy and motor block profile of single-shot transmuscular quadratus lumborum block (QLB) in comparison with those of suprainguinal fascia iliaca block (FIB) in patients undergoing hip arthroplasty. ⋯ The study was registered at clinical trials registry system before enrollment of the first participant (NCT04005326; initial release date, 2 July 2019; https://clinicaltrials.gov/ct2/show/NCT04005326).

Posterior knee pain after total knee arthroplasty (TKA) is common despite multimodal analgesia and regional anesthesia use. This review included randomized controlled trials (RCTs) comparing analgesic outcomes after inclusion of local anesthetic infiltration between the popliteal artery and capsule of the knee (iPACK) block versus pathways without iPACK. Electronic databases (MEDLINE, Cochrane Library, Web of Science, Scopus) were searched from inception to 10/11/2020. ⋯ Studies consistently reported no difference in gait distance (4/4 RCTs) or complications (7/7 RCTs) between treatment arms (high-quality GRADE evidence), although differing effect estimates were observed with resting pain, satisfaction, LOS, and knee ROM. This review provides a foundation of knowledge on iPACK efficacy. While evidence does not currently support widespread inclusion of iPACK within enhanced recovery pathways for TKA, limitations suggest further study is warranted.

Defined in the last decade, erector spinae plane block (ESPB) is one of the more frequently used interfacial plans, and it has been the most discussed block among the recently defined techniques. Lumbar ESPB administered at lumbar levels is relatively novel and is a new horizon for regional anesthesia and pain practice. In this article, we aim to explain and introduce different approaches and explain the possible mechanism of action of lumbar ESPB. ⋯ After a selection of the relevant studies, 59 articles were found eligible and were included in this review. While we believe that lumbar ESPB is reliable and easy, we suggest that its efficacy and indications should be verified with anatomical and clinical studies, and its safety should be confirmed with pharmacokinetic studies. Moreover, the possibility of complications must be considered.

Laparoscopic abdominal surgery has become a mainstay of modern surgical practice. Postoperative analgesia is an integral component of recovery following laparoscopic abdominal surgery and may be improved by regional anesthesia or intravenous lidocaine infusion. ⋯ Aside from the locations of the surgical incisions, it is unclear what other factors should be considered when choosing one regional technique over another or deciding to infuse lidocaine intravenously. We reviewed the current literature in attempt to clarify the roles of various regional anesthesia techniques for patients undergoing laparoscopic abdominal surgery and present one possible approach to evaluating postoperative pain.
