Randomized Controlled TrialPostoperative Analgesic Effect of Ultrasound-Guided Intermediate Cervical Plexus Block on Unipolar Sternocleidomastoid Release With Myectomy in Pediatric Patients With Congenital Muscular Torticollis: A Prospective, Randomized Controlled Trial.
Unipolar sternocleidomastoid release with myectomy (USRM) for correction of congenital muscular torticollis in pediatric patients produces moderate to severe postoperative pain. The objective of this trial was to examine the effect of ultrasound-guided intermediate cervical plexus block on postoperative pain after USRM. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02651311.

Randomized Controlled Trial Comparative StudyPerineural Low-Dose Dexamethasone Prolongs Interscalene Block Analgesia With Bupivacaine Compared With Systemic Dexamethasone: A Randomized Trial.
Perineural dexamethasone and intravenous (IV) dexamethasone have been shown to prolong peripheral nerve block duration. The effects of perineural and IV dexamethasone have only been compared at doses of 4 mg or greater. This triple-blind, randomized trial examined the effect of 1 mg IV versus perineural dexamethasone on interscalene block (ISB) analgesia duration. ⋯ This study was registered at Clinicaltrials.gov, identifier NCT02506660.

Real-Time Ultrasound-Assisted Thoracic Epidural Placement: A Feasibility Study of a Novel Technique.
The placement of thoracic epidural catheters is complicated by the layering of the vertebral lamina. Therefore, traditional blind palpation techniques require insertion of an epidural needle with likely contact of lamina with redirections into the epidural space. ⋯ Successful epidural placement was achieved in every patient. All catheters were found to be effective for use in the postoperative phase.

Randomized Controlled TrialUltrasound-Guided Percutaneous Peripheral Nerve Stimulation: Neuromodulation of the Sciatic Nerve for Postoperative Analgesia Following Ambulatory Foot Surgery, a Proof-of-Concept Study.
Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain the day following knee surgery. However, it remains unknown if this analgesic technique may be used in ambulatory subjects following foot procedures beginning within the recovery room immediately following surgery, and with only short series of patients reported to date, the only available data are derived from strictly observational studies. The purposes of this proof-of-concept study were to demonstrate the feasibility of using percutaneous sciatic nerve PNS to treat postoperative pain following ambulatory foot surgery in the immediate postoperative period and provide the first available data from a randomized controlled study design to provide evidence of analgesic effect. ⋯ This study was registered at Clinicaltrials.gov, identifier NCT02898103.

Randomized Controlled Trial Comparative StudyA Randomized Comparison Between Interscalene and Small-Volume Supraclavicular Blocks for Arthroscopic Shoulder Surgery.
This randomized trial compared ultrasound (US)-guided interscalene block (ISB) and small-volume supraclavicular block (SCB) for arthroscopic shoulder surgery. We hypothesized that SCB would provide equivalent analgesia to ISB 30 minutes after surgery without the risk of hemidiaphragmatic paralysis (HDP). ⋯ This study was registered at ClinicalTrials.gov, identifier NCT03224884.
