Review Meta AnalysisUltrasound-Guided Interventional Procedures in Pain Medicine: A Review of Anatomy, Sonoanatomy, and Procedures. Part V: Knee Joint.
Ultrasound-guided injection in pain medicine is emerging as a popular technique for pain intervention. It can be applied to the intra-articular injection of the knee joint. The first objective of this review was to describe and summarize the anatomy and sonoanatomy of the knee and associated structures relevant for intra-articular injection. The second objective was to examine the feasibility, accuracy, and effectiveness of injections as well as injection techniques.

Randomized Controlled TrialUltrasound-Guided Continuous Interscalene Block: The Influence of Local Anesthetic Background Delivery Method on Postoperative Analgesia After Shoulder Surgery: A Randomized Trial.
Automated bolus delivery has recently been shown to reduce local anesthetic consumption and improve analgesia, compared with continuous infusion, in continuous sciatic and epidural block. However, there are few data on the influence of local anesthetic delivery method on local anesthetic consumption following interscalene blockade. This randomized, double-blind trial was designed to determine whether hourly automated perineural boluses (4 mL) of local anesthesia delivered with patient-controlled pro re nata (PRN, on demand) boluses would result in a reduction in total local anesthesia consumption during continuous interscalene blockade after shoulder surgery compared with continuous perineural infusion (4 mL/h) plus patient-controlled PRN boluses. ⋯ In continuous interscalene blockade under ultrasound guidance after shoulder surgery, automated boluses of local anesthetic combined with PRN boluses did not provide any reduction in local anesthetic consumption or rescue analgesia, compared with continuous infusion combined with PRN boluses.

Randomized Controlled TrialAdherence to guidelines for the management of local anesthetic systemic toxicity is improved by an electronic decision support tool and designated "reader".
A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated "Reader" role on team performance during an in situ simulation of LAST. ⋯ In a prospective, randomized single-blinded study, a designated Reader with an electronic DST improved adherence to guidelines in the management of an in situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena.
