ReviewUltrasound-Guided Interventional Procedures: Myofascial Trigger Points With Structured Literature Review.
Ultrasound-guided injections in pain medicine are a common intervention. They have been used to manage myofascial trigger points (MTrPs) in different muscles of the body. The main objectives of this article were to review ultrasound-guided injection techniques used for treating MTrPs. We also summarize the anatomy and sonoanatomy of MTrPs using the upper trapezius muscle as an example.

Randomized Controlled Trial Comparative StudyA Randomized Comparison Between Ultrasound- and Fluoroscopy-Guided Sacral Lateral Branch Blocks.
This randomized trial compared ultrasound (US)- and fluoroscopy-guided sacral lateral branch (SLB) blocks. We hypothesized that US would require a shorter performance time. ⋯ Compared with their fluoroscopic counterparts, US-guided SLB blocks require a shorter performance time as well as fewer needle passes and carry a lower risk of vascular breach.

Comparative StudyAdherence to a Multimodal Analgesic Clinical Pathway: A Within-Group Comparison of Staged Bilateral Knee Arthroplasty Patients.
Multimodal analgesic clinical pathways for joint replacement patients often include perineural catheters, but long-term adherence to these pathways has not yet been investigated. Our primary aim was to determine adherence rate to a knee arthroplasty clinical pathway for patients undergoing staged bilateral procedures. ⋯ For staged bilateral knee arthroplasty patients, 100% clinical pathway adherence including perineural catheters and multimodal analgesia is feasible despite multiple variables. We believe that patient-centered acute pain management requires consistent and reliable delivery of care.

Synergistic Effects of Serotonin or Dopamine Combined With Lidocaine at Producing Nociceptive Block in Rats.
The purpose of this experiment was to investigate the interactions of the local anesthetic lidocaine combined with an agent (serotonin or dopamine) as infiltrative anesthetics. ⋯ The preclinical data showed that serotonin and dopamine produce dose-related cutaneous analgesic effects as an infiltrative anesthetic. Serotonin has a better potency with a much longer duration of action compared with lidocaine at provoking cutaneous analgesia. Serotonin or dopamine as an adjuvant increases the quality of lidocaine in cutaneous analgesia.
