Postoperative analgesia is an integral component of recovery following laparoscopic abdominal surgery and may be improved by regional anesthesia or intravenous lidocaine infusion. There is inconsistent evidence supporting the use of interfascial plane blocks, such as transversus abdominis plane (TAP) blocks, for patients undergoing laparoscopic abdominal surgery as evidenced by variable patterns of local anesthetic spread and conflicting results from studies comparing TAP blocks to local anesthetic infiltration of laparoscopic port sites and multimodal analgesia. Quadratus lumborum (QL) and erector spinae plane (ESP) blocks may provide greater areas of somatic analgesia as well as visceral analgesia, which may translate to more significant clinical benefits. 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.</p>","PeriodicalId":18203,"journal":{"name":"Local and Regional Anesthesia","volume":"13 ","pages":"159-169"},"PeriodicalIF":2.9,"publicationDate":"2020-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/LRA.S272694","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38640723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the use of regional anesthesia in these areas has potential benefits regarding access, safety, and cost-effectiveness. Perioperative anesthesia-related mortality is significantly higher in resource-limited countries and every effort should be made to encourage the use of anesthetic techniques in these countries that are safest under the present conditions. Studies from Sub-Saharan Africa, although limited in number, have shown a lower risk of death with regional compared to general anesthesia. Regional anesthesia has the further benefit of decreasing the risk of COVID-19 spread to healthcare providers by avoiding the aerosol-generating procedures that occur during general anesthesia. Neuraxial regional anesthesia is relatively easy to teach and perform and is considered the anesthetic of choice for surgeries below the umbilicus in resource-limited settings due to its safety, efficacy, and low cost. Although regional anesthesia has multiple potential advantages, education and training of anesthetic providers in low-and-middle-income countries (LMIC) are a significant barrier to growth. Anesthesia professionals, especially in Sub-Saharan Africa, are often poorly supported and undervalued, and recruitment and retention of adequate numbers of trained practitioners are a continuing problem. Greater use of regional anesthesia could be one way to safely increase anesthesia access and simultaneously create value and enthusiasm for the field. Deficits in anesthesia infrastructure, equipment, and drugs also limit anesthesia capacity in low-and middle-income countries. Ultrasound-guided regional anesthesia may be helpful in improving access to safe and reliable anesthesia in low-resource countries as it continues to become more user-friendly, durable, and affordable.</p>","PeriodicalId":18203,"journal":{"name":"Local and Regional Anesthesia","volume":"13 ","pages":"147-158"},"PeriodicalIF":1.5,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/22/ff/lra-13-147.PMC7588832.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38640722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although nerve enlargement is characteristic of demyelinating diseases such as CMTD, the use of ultrasonography in the diagnosis of neurological disorders is a developing area for neurologists and anesthesiologists can lack knowledge in this emerging field. Unusual nerve presentation on ultrasonographic images during PNB anesthetic procedures should be recognized as being indicative of underlying neurologic disorders. This case highlights that increased awareness of the diagnosis of underlying neurologic disorders by ultrasonography would assist the general practice of PNB in anesthetic medicine. This is especially important as underlying neurological conditions can have important consequences for patient-appropriate anesthesia and may inform best anesthetic practice.
