Practice 'safe scans': why ultrasound transducer covers should be considered best practice.
Single-injection, ultrasound-guided nerve block procedures involve puncturing the skin in close proximity to an ultrasound transducer, creating a potential vector for transmission of microbial organisms when skin flora and blood come into contact with the probe. Practice patterns regarding disinfection of the transducer and the use of barrier protection are inconsistent, ranging from sterile sleeve probe covers to no cover at all. ⋯ This position is shared by multiple societies and authorities on ultrasound and acute care medicine. In this Daring Discourse, we outline the arguments supporting the utilisation of single-use sleeve probe covers to ensure patient safety with respect to vector-borne transmission of microbes during single-injection regional anaesthesia procedures.

Randomized Controlled Trial Comparative Study
Ultrasound guided quadratus lumborum block versus interlaminar epidural block for analgesia in pediatric abdominal surgery: a randomized controlled trial.
Although the efficacy and safety of epidural block (EB) are fairly high, complications such as inadvertent dural puncture may limit its use. Ultrasound-guided quadratus lumborum block (QLB) is a relatively new regional technique that provides perioperative somatic and visceral analgesia for pediatric patients. This trial compared the quality of pain relief in pediatric patients undergoing abdominal surgery who received either QLB or EB. ⋯ PACTR202203906027106.

Meta Analysis Comparative Study
Comparison of fascia iliaca block with quadratus lumborum block for hip arthroplasty: A meta-analysis of randomized controlled trials.
The efficacy of fascia iliaca block (FIB) versus quadratus lumborum block (QLB) remains controversial for pain management of hip arthroplasty. We conduct a systematic review and meta-analysis to explore the influence of FIB versus QLB on the postoperative pain intensity of hip arthroplasty. ⋯ FIB may be better than QLB for pain control after hip arthroplasty, as evidenced by the lower pain scores at 2 and 24 hours.

0.25% bupivacaine-1% lidocaine vs 0.5% bupivacaine for ultrasound-guided infraclavicular brachial plexus block: a randomized controlled trial.
In an effort to shorten onset time, a common practice is to add lidocaine to bupivacaine. In the setting of infraclavicular block, it is unclear what the block characteristics of this practice are compared with bupivacaine alone. We hypothesized that bupivacaine alone increases the duration of motor block, sensory block, and postoperative analgesia while resulting in a slower onset time compared with a bupivacaine and lidocaine mixture. ⋯ Compared with mixed bupivacaine-lidocaine, 0.5% bupivacaine significantly prolongs sensorimotor block and postoperative analgesia at the expense of a delayed onset time.

ReviewExtended reality navigation for pain procedures: a narrative review.
Extended reality (XR) technology, encompassing virtual reality, augmented reality, and mixed reality, has been widely studied for procedural navigation in surgical specialties. Similar to how ultrasound transformed regional anesthesia, XR has the potential to reshape how anesthesiologists and pain physicians perform procedures to relieve pain. ⋯ Early randomized controlled trials show potential for XR to improve procedural efficiency, but more comprehensive research is needed to determine if there are significant clinical benefits. Case reports demonstrate XR's utility in generating patient-specific navigation plans when difficult anatomy is encountered. Procedures that facilitate the generation and registration of XR images are most conducive to XR navigation, whereas those that rely on frequent re-imaging will continue to depend on traditional modes of navigation.
