Exploring the utility of assistive artificial intelligence for ultrasound scanning in regional anesthesia.
Ultrasound-guided regional anesthesia (UGRA) involves the acquisition and interpretation of ultrasound images to delineate sonoanatomy. This study explores the utility of a novel artificial intelligence (AI) device designed to assist in this task (ScanNav Anatomy Peripheral Nerve Block; ScanNav), which applies a color overlay on real-time ultrasound to highlight key anatomical structures. ⋯ ScanNav shows potential to support non-experts in training and clinical practice, and experts in teaching UGRA. Such technology may aid the uptake and generalizability of UGRA.

Review Meta Analysis
Analgesic efficacy of erector spinae plane block in lumbar spine surgery: A systematic review and meta-analysis.
Erector spinae plane block (ESPB) has gained popularity for perioperative analgesia in various surgeries. However, its efficacy in lumbar surgery remains unclear. This review aimed to determine whether ESPB could improve analgesic efficacy in lumbar spine surgery. ⋯ ESPB provided effective postoperative analgesia resulting in better patient satisfaction and recovery with decreased postoperative nausea and vomiting in patients undergoing lumbar surgery compared to the control. However, the low-grade quality of evidence compromised the findings, therefore further high-quality of evidence is required. PROSPERO registration number: CRD42021233362.

Randomized Controlled TrialBilateral lumbar ultrasound-guided erector spinae plane block versus local anaesthetic infiltration for perioperative analgesia in lumbar spine surgery: a randomized controlled trial.
Lumbar spinal surgery is associated with severe postoperative pain. We examined the analgesic efficacy of bilateral lumbar ultrasound-guided erector spinae plane block (ESPB) with ropivacaine compared with local infiltration. ⋯ Bilateral ultrasound-guided ESPB offers improved postoperative analgesia compared with local infiltration in patients undergoing lumbar spinal surgery.

Randomized Controlled TrialEffect of Lidocaine 2% Versus Bupivacaine 0.5% and 1 Versus 2 Dual Separate Injections on Onset and Duration of Ultrasound-Guided Wrist Blocks: A Blinded 2 × 2 Factorial Randomized Clinical Trial.
Local anesthetics are often selected or mixed to accomplish faster onset of anesthesia. However, with ultrasound guidance, local anesthetics are delivered with greater precision, which may shorten the onset time with all classes of local anesthetics. In this study, we compared onset time and duration of ultrasound-guided wrist blocks with a fast onset versus a longer lasting local anesthetic administered via single or dual (spatially separate) injections at the level of the midforearm. ⋯ No significant effect was found for onset time between lidocaine 2% and bupivacaine 0.5% used in ultrasound-guided wrist blocks. Dual injections did not shorten onset time. Since mean nerve block duration was longer with bupivacaine 0.5%, our results suggest that the selection of local anesthetic for the median and ulnar nerves at the level of the midforearm should be based on the desired duration of the block and not on its speed of onset.
