Randomized Controlled Trial Comparative Study
Continuous block at the proximal end of the adductor canal provides better analgesia compared to that at the middle of the canal after total knee arthroplasty: a randomized, double-blind, controlled trial.
The optimal position for continuous adductor canal block (ACB) for analgesia after total knee anthroplasty (TKA) remians controversial, mainly due to high variability in the localization of the the adductor canal (AC). Latest neuroanatomy studies show that the nerve to vastus medialis plays an important role in innervating the anteromedial aspect of the knee and dives outside of the exact AC at the proximal end of the AC. Therefore, we hypothesized that continuous ACB at the proximal end of the exact AC could provide a better analgesic effect after TKA compared with that at the middle of the AC (which appeared to only block the saphenous nerve). ⋯ Continuous ACB at the proximal end of the AC has a better opioid-sparing effect without a significant influence on quadriceps motor strength compared to that at the middle of the AC after TKA. These findings indicates that a true ACB may not produce the effective analgesia, instead, the proximal end AC might be a more suitable block to alleviate pain after TKA.

Randomized Controlled Trial
Erector spinae plane block for postoperative pain and recovery in hepatectomy: A randomized controlled trial.
The randomized controlled study aimed to examine the efficacy of preoperative ultrasound-guided erector spinae plane (ESP) block combined with ropivacaine in patients undergoing hepatectomy. ⋯ ESP block combined with ropivacaine treatment effectively reduced early postoperative pain and improved recovery after hepatectomy.

Case Reports
Erector spinae plane block with catheter for management of percutaneous nephrolithotomy: A three case report.
Percutaneous nephrolithotomy is a procedure used for management of refractory renal calculi. Oral and parenteral opioids, along with local anesthetic infiltration, neuraxial anesthesia, and paravertebral blocks are the most common methods of managing intra-operative and post-operative pain for these patients. The erector spinae plane block with catheter (ESPC) is a newer interfascial regional anesthetic technique that can be used to manage peri-operative pain in these patients. ⋯ These patients were compared to 3 prior patients who had undergone percutaneous nephrolithotomy without ESPC. The 3 patients without ESPC placement reported increased VAS scores, had increased opioid/pain medication consumption intraoperatively and postoperatively, and had increased incidence of perioperative nausea when compared to our ESPC patients. Our report shows that ESPC, in combination with a multimodal pain protocol, can be a good option for management of patients undergoing percutaneous nephrolithotomy.

ReviewHas the future arrived? Liposomal bupivacaine versus perineural catheters and additives for interscalene brachial plexus block.
Single injection interscalene block (ISB) provides effective analgesia for shoulder surgery. However, the duration of these is limited. This review summarizes the effectiveness of three potential means of extending the duration of analgesia: perineural infusion of local anesthetic agents, addition of adjuvant drugs to local anesthetics in single-injection nerve block, and utilization of liposomal bupivacaine in the surgical field or in the block itself. ⋯ Interscalene catheters, adjunctive drugs added to local anesthetics in single-injection interscalene brachial plexus blocks, or liposomal bupivacaine may be used to effectively prolong the duration of analgesia for shoulder surgery patients.

ReviewWrong-site nerve blocks: evidence-review and prevention strategies.
There has been increasing attention to wrong site medical procedures over the last 20 years. This review aims to provide a summary of the current understanding and recommendations for the prevention of wrong-site nerve blocks (WSNB). ⋯ Though the evidence is limited, it is recommended that a combination of multiple strategies should be employed to prevent WSNB. These include the use of preprocedural markings, well constructed checklists, time-out/stop-moments, and cognitive/physical aids. Effective implementation requires team education and engagement that empowers all team members to speak up as part of a culture of safety.
