Aim: This study evaluated use of liposomal bupivacaine (LB) versus standard bupivacaine (SB) alone in quadratus lumborum (QL) blocks for laparoscopic colorectal surgery. Materials & methods: In this prospective, randomized controlled trial, patients received QL1 blocks with either LB (40 ml 0.125% SB plus 20 ml of LB) or SB (60 ml of 0.25% SB) with 30 ml per side. Opioid usage, pain scores, side effects and other medications were recorded. Results: For 78 patients (38 LB; 40 SB), all parameters were similar between groups, except that the LB group had a higher 48 h need for metoclopramide. Conclusion: LB provided no analgesic benefit over SB alone for QL blocks. Clinical Trials registration number: NCT03702621

Background and objectivesThe objective of the study was to determine if injection of local anesthetic into the vastus medialis and sartorius muscles adjacent to the adductor canal produces sensory changes comparable with adductor canal block (ACB). This could result in a technically easier and potentially safer alternative to ACB.MethodsIn this randomized controlled trial, patients received either ACB (n=20) or a simplified adductor canal (SAC) block performed using a new fenestrated nerve block needle (n=20). The time to perform each block as well as the number of attempts to position the needle were evaluated. A non-inferiority test was used to compare pain scores and opioid requirements for the ACB and the SAC block.ResultsThe SAC block was performed more rapidly, with fewer needle passes, and had a higher success rate than the ACB. Three block failures and two vessel punctures were observed in the ACB group, while none of these events occurred in SAC block patients. Analgesia and opioid consumption for patients treated with the SAC block were not inferior to ACB.ConclusionThe SAC block is technically easier to perform and potentially safer than ACB. This procedure can be performed using easily visible ultrasound landmarks and has the potential for use among a wide range of healthcare providers.Trial registration numberNCT02786888.
