BACKGROUND AND OBJECTIVES: Regional anesthesia includes application of local anesthetics (LAs) into the vicinity of peripheral nerves. Prolongation or improvement of nerve blocks with LAs can be accomplished by coapplication with adjuvants, including buprenorphine, ketamine, and clonidine. While the mechanisms mediating prolonged or improved LA-induced effects by adjuvants are poorly understood, we hypothesized that they are likely to increase LA-induced block of voltage-gated Na channels...

BACKGROUND AND OBJECTIVES: The aim of this study was to analyze histological nerve toxicity of perineural dexamethasone administration in combination with ropivacaine on mice. Efficacy of perineural dexamethasone in combination with regional anesthesia is clearly demonstrated. However, the safety of this procedure is still a matter of debate. METHODS: A sciatic nerve block was performed on 90 mice. Five groups, each containing 18 mice assigned randomly, were used in these experiments: the sham group (isotonic saline solution), R group (perineural ropivacaine), D group (perineural dexamethasone), RDPN group (perineural ropivacaine and perineural dexamethasone), and the RDS group (perineural ropivacaine and systemic dexamethasone)...

OBJECTIVE: Our objective was to describe the first reported use of an axillary brachial plexus block to treat the entrapment of a transradial artery catheter due to vasospasm. CASE REPORT: A 42-year-old man undergoing transradial arterial cardiac catheterization suffered arterial vasospasm causing the catheter to become entrapped and refractory to conservative (warm compresses) and standard pharmacologic interventions (intracatheter verapamil, intravenous infusions of nitroglycerin and nicardipine, and subcutaneous lidocaine and topical nitroglycerin)...

BACKGROUND AND OBJECTIVES: While benefits of regional anesthesia in total hip arthroplasty (THA) are well documented, data describing the incidence of complications related to the use of posterior lumbar plexus blockade for THA remain limited. Our primary aim was to evaluate the incidence of infectious, bleeding, and neurological complications related specifically to the use of continuous posterior lumbar plexus block for elective THA. METHODS: We reviewed the electronic medical records of all adult patients who underwent elective THA with continuous posterior lumbar plexus blockade between December 1, 2004, and April 30, 2015, using the Mayo Clinic Total Joint Registry...

BACKGROUND AND OBJECTIVES: The infiltration of local anesthetic is consistently described as painful by patients. Vibration anesthesia has been studied in the dental literature as a promising tool to alleviate the pain from dental nerve blocks. Many of these studies used a specific device, the DentalVibe. To date, there have not been any studies applying this technology to digital blocks of the hand in human subjects. We hypothesized that the use of microvibratory stimulation during digital blocks of the hand would decrease pain reported by patients...

Surgery of the wrist and hand commonly involves regional anesthesia of the median nerve and superficial radial nerve within the forearm. In this sonographic study, the contribution of the lateral cutaneous nerve of forearm (LCNF) to thumb cutaneous sensation was studied. Patients scheduled for thumb suspension arthroplasty (n = 35) were examined by ultrasound, with LCNF, median nerve, and superficial radial nerve identified. A single nerve was then injected with local anesthetic, and the area of cutaneous sensory loss mapped at 15 minutes...

BACKGROUND AND OBJECTIVES: Thoracic epidural anesthesia is a technically challenging procedure with a high failure rate of 24% to 32% nationwide. Residents in anesthesiology have limited opportunities to practice this technique adequately, and there are no training tools available for this purpose. Our objective was to build a low-cost patient-specific thoracic epidural training model. METHODS: We obtained thoracic computed tomography scan data from patients with normal and kyphotic spine...

In this article, we discuss the emerging role of lung point-of-care ultrasonography for regional anesthesiologists and pain management specialists. Lung ultrasonography is a well-established clinical tool that is used on a routine basis in emergency rooms and critical care units internationally to evaluate patients with respiratory distress; however, its benefits to the regional anesthesiologist and pain specialist are not as well known and are practiced less frequently. This review article covers the clinical evidence in support of lung point-of-care ultrasonography as a rapid and superior tool to traditional imaging modalities such as chest radiography and fluoroscopy...

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.

Postoperative pain after bariatric surgery can be significant and yet difficult to manage. These patients frequently have associated obstructive sleep apnea and are at risk of respiratory depression with opioid analgesia. Abdominal wall blocks such as the subcostal transversus abdominis plane block are not of significant benefit, probably in part because they provide only somatic analgesia. The ultrasound-guided erector spinae plane (ESP) block is a recently described regional anesthetic technique for providing thoracic analgesia when performed at the level of the T5 transverse process...
