AIM: Regional anesthesia with ultrasound-guidance is an excellent option for pain control if nerves are adequately visualized. Gender, body mass index (BMI), history of diabetes, neck and forearm circumference may affect echotexture and visualization. This study evaluates patient characteristics for their ability to predict the echogenicity or visibility of upper extremity peripheral nerves. MATERIAL AND METHODS: This is a prospective observational study. A convenience sample of adult emergency department patients were enrolled...

A 72-year-old man with ischemic cardiomyopathy was referred to undergo an implantation of a cardiac implantable electrical device (CIED). A pocket was created subcutaneously on the left anterior chest. After the operation, he complained of severe pain irradiating to his left posterior shoulder. The local anesthetic nerve block by a local infusion of mepivacaine revealed the pain was associated with the supraclavicular nerve. We re-created the pocket and shifted the generator toward the inner side, and the irradiating pain vanished...

BACKGROUND AND OBJECTIVES: 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). METHODS: All patients received an US-guided intermediate cervical plexus block. In the ISB group, US-guided ISB was performed with 20 mL of levobupivacaine 0...

Background: Dexamethasone as an adjuvant to bupivacaine and ropivacaine for supraclavicular brachial plexus (SCBP) block prolongs motor and sensory blockade. However, comparison of effect of dexamethasone (8 mg) when added to these two local anesthetics has not been well studied. This study was conducted to compare analgesic efficacy of dexamethasone as adjuvant to bupivacaine and ropivacaine in SCBP block. Subjects and Methods: Nerve stimulator-guided SCBP block was given to 120 patients, randomly assigned to one of four groups: ( n = 30 in each group) Group B, BD, R, and RD received 30 ml (0...

Background: The supraclavicular approach is considered to be the easiest and most effective approach to block the brachial plexus for upper limb surgeries. The classical approach using the anatomical landmark technique was associated with higher failure rates and complications. Ultrasonography (USG) guidance and peripheral nerve stimulator (PNS) have improved the success rates and safety margin. Aims: The aim of the present study is to compare USG with PNS in supraclavicular brachial plexus block for upper limb surgeries with respect to the onset of motor and sensory blockade, total duration of blockade, procedure time, and complications...

BACKGROUND: Located in the neck beneath the sternocleidomastoid muscle, the cervical plexus comprises a coalition of nerves originating from C1 through C4, which provide input to four cutaneous, seven motor, and three cranial nerves and the sympathetic trunk. Sporadic instances of injury to these superficial nerves have been reported. Nevertheless, this specific anatomical cause of neurogenic pain remains incompletely described and underrecognized. METHODS: Twelve patients presented with pain and were diagnosed with various combinations of injury to the lesser occipital, great auricular, transverse cervical, and supraclavicular nerves...

Plexiform neurofibroma is pathognomonic of neurofibromatosis 1 (NF1). An NF1-associated peripheral neuropathy has been described in a small minority of NF1 patients but its histopathological features are poorly characterized. We report the case of a 46-year-old woman presenting with bilateral supraclavicular painful masses without other stigmata of NF1. MRI showed bilateral plexiform lesions extending from cervical roots to the elbows. Nerve conduction studies documented a sensory motor polyneuropathy. Morphometric analysis of sural nerve biopsy showed a preferential loss of large-caliber myelinated fibers with a g ratio of 0...

A sclerosing perineurioma presents as a single asymptomatic papule or nodule located on the hands of adult patients; approximately 60 cases have been reported in medical literature since 1997. Histologically, it originates from the perineural cells of the peripheral nerves and presents epithelial membrane antigen (EMA) positivity and S100 protein negativity. Here, we present the case of a 58-year-old male admitted to our surgery unit complaining of left supraclavicular swelling of 1-cm in size, having no significant past medical history...

The thesis comprises an overview and four papers, all published or submitted for publication in international peer-reviewed scientific journals.
 
Chronic pain after surgery is a common and debilitating complication after many types of surgery. The cause and pathology behind is still mainly uncovered, though several risk factors have been proposed. One of the strongest risk factors for persistent postsurgical pain is the intensity of the acute pain response though the mechanisms involved remain unsettled...

INTRODUCTION: We describe a new nerve conduction study technique with reference values for the 3 branches of the supraclavicular nerve (SCN) in young healthy subjects and application of it in 2 patients. METHODS: The recording electrode was placed on the posterior border of the sternocleidomastoid muscle, 6-7 cm from the sternoclavicular joint. SCN branches were stimulated below the clavicle, 2.5, 7, and 10.5 cm lateral to the sternoclavicular joint. RESULTS: Twenty healthy volunteers (10 men), 19-38 years, mean 25...

BACKGROUND: The aim of the study was to investigate the difference between intraneural and perineural injection pressures in human cadavers. Targeted nerves included the cervical roots, the supraclavicular and infraclavicular brachial plexus, the sciatic-subgluteal nerve and the common peroneal and tibial nerves. METHODS: Ten readings were obtained for each nerve location. 1mL of 0.9% NaCl was injected over ten seconds - deliberately slower than in clinical practice to eliminate the risk of aberrant readings relating to the speed of injection...

We describe a rare case of an anatomical variant of the supraclavicular nerve in the intra-operative setting of clavicle fixation for a fracture. Intra-operatively it was noted that one of the supraclavicular nerves was passing through a foramen in the clavicle shaft. A 60-year-old gentleman presented with a displaced multifragmentary fracture of the left clavicle after a fall. Plate fixation with a pre-contoured locking plate was performed under general anaesthesia. The clavicle was exposed through an infraclavicular transverse incision...
