During the routine dissection classes for undergraduate students, uncommon variation in relation to the upper subscapular nerve of posterior cord of brachial plexus was observed. Normally upper subscapular nerve takes origin from the posterior cord, but in this case report, it arises in triplet fashion, just above the circumflex scapular artery. All these accessory nerves were supplying upper part of the subscapularis muscle. As per our knowledge, this is a rare variation of brachial plexus. Many variations are encountered in the formation of brachial plexus...

Twenty thoracic limbs of ten Lycalopex gymnocercus were dissected to describe origin and distribution of the nerves forming brachial plexuses. The brachial plexus resulted from the connections between the ventral branches of the last three cervical nerves (C6, C7 and C8) and first thoracic nerve (T1). These branches connected the suprascapular, subscapular, axillary, musculocutaneous, radial, median and ulnar nerves to the intrinsic musculature and connected the brachiocephalic, thoracodorsal, lateral thoracic, long thoracic, cranial pectoral and caudal pectoral nerves to the extrinsic musculature...

BACKGROUND: Ultrasound-guided techniques improve outcomes in regional anesthesia when compared with traditional techniques; however, this assertion has not been studied with novices. The primary objective of this study was to compare sensory and motor block after axillary brachial plexus block when performed by novice trainees allocated to an ultrasound- or nerve-stimulator-guided group. A secondary objective was to compare the rates of skill acquisition between the 2 groups. METHODS: This study was a prospective, randomized, observer-blinded, 2-arm controlled trial...

BACKGROUND: Regional anaesthesia comprising axillary block of the brachial plexus is a common anaesthetic technique for distal upper limb surgery. This is an update of a review first published in 2006 and previously updated in 2011 and 2013. OBJECTIVES: To compare the relative effects (benefits and harms) of three injection techniques (single, double and multiple) of axillary block of the brachial plexus for distal upper extremity surgery. We considered these effects primarily in terms of anaesthetic effectiveness; the complication rate (neurological and vascular); and pain and discomfort caused by performance of the block...

In the axillary fossa, the musculocutaneous nerve (MC) is generally distant from the axillary artery and from the other brachial plexus nerves. In that way, MC requires a specific block. We observed that the location of MC is influenced by the position of the patient's arm and shoulder. Abduction of the shoulder significantly reduced the distance between the MC and the axillary artery. This change in the location of the MC is probably due to the moving of the nerve because of muscle rearrangements and the ability to achieve better proximity of the probe in the axillary fossae...

PURPOSE: Limited data exist regarding the role of perineural blockade of the distal median, ulnar, and radial nerves as a primary anesthetic in patients undergoing hand surgery. We conducted a prospective and randomized pilot study to compare these techniques to brachial plexus blocks as a primary anesthetic in this patient population. METHODS: Sixty patients scheduled for hand surgery were randomized to receive either an ultrasound-guided supraclavicular, infraclavicular, or axillary nerve block (brachial plexus blocks) or ultrasound-guided median, ulnar, and radial nerve blocks performed at the level of the mid to proximal forearm (forearm blocks)...

INTRODUCTION: Variations in the brachial plexus are the rule rather than the exception. This fact is of special interest for the anesthetist when planning axillary block of brachial plexus. MATERIAL AND METHODS: 167 cadaver arms were evaluated for variations in brachial plexus, with focus on the cords of the plexus, the loop of the median nerve, and the course of the median, musculocutaneous, ulnar, axillary and radial nerves. In addition, concomitant arterial variations were recorded...

PURPOSE: To update the gross and sonographic anatomy and propose landmarks to perform ultrasound-guided (US-guided) axillary brachial plexus block (BPB) in rabbits. METHODS: Forty New Zeeland's rabbit (NZR) cadavers were dissected and the nerves were trimmed, identified, measured, and photographed. Additionally, in twenty NZRs, sonographic images of brachial plexus (BP) were performed through a simple-resolution ultrasound device. The US-guided block was achieved through a minimum volume of lidocaine necessary to surround the BP roots...

OBJECTIVE: We hypothesized that ultrasound (US)-guided technique of the supra- and infraclavicular and axillary approaches of brachial plexus block (BPB) will produce a high quality of surgical anesthesia for operations below the shoulder independently of the approach and body mass index (BMI). Intercostobrachial and medial brachial cutaneous nerves will be blocked separately because they are not a part of the brachial plexus. METHODS: This is a prospective randomized observer-blinded study...

BACKGROUND AND OBJECTIVES: The costoclavicular space (CCS), which is located deep and posterior to the midpoint of the clavicle, may be a better site for infraclavicular brachial plexus block than the traditional lateral paracoracoid site. However, currently, there is paucity of data on the anatomy of the brachial plexus at the CCS. We undertook this cadaver anatomic study to define the anatomy of the cords of the brachial plexus at the CCS and thereby establish the anatomic basis for ultrasound-guided infraclavicular brachial plexus block at this proximal site...

The Direct Observation of Procedural Skills (DOPS) form is used as a workplace-based assessment tool in the current Australian and New Zealand College of Anaesthetists curriculum. The objective of this study was to evaluate the reliability of DOPS when used to score trainees performing ultrasound-guided regional anaesthesia. Reliability of an assessment tool is defined as the reproducibility of scores given by different assessors viewing the same trainee. Forty-nine anaesthetists were recruited to score two scripted videos of trainees performing a popliteal sciatic nerve block and an axillary brachial plexus block...

BACKGROUND: Addition of dexmedetomidine to ropivacaine for peripheral nerve blocks has shown to improve the efficacy of ropivacaine by prolonging the duration of analgesia. This study was undertaken to evaluate the effects of ropivacaine alone and in combination with dexmedetomidine in the axillary block. MATERIALS AND METHODS: A total of 80 patients belonging to American Society of Anesthesiologists physical status I, II, and III, scheduled for elective forearm and/or hand surgeries were randomly allocated into one of the two groups to receive either 39 ml of 0...

BACKGROUND: For ages various adjuvants have been tried to prolong axillary brachial plexus block. We compared the effect of adding dexmedetomidine versus clonidine to ropivacaine for axillary brachial plexus blockade. The primary endpoints were the onset and duration of sensory and motor block and duration of analgesia. MATERIALS AND METHODS: A total of 90 patients (20-40 years) posted for ambulatory elective hand surgery under axillary brachial plexus block were divided into two equal groups (groups ropivacaine dexmedetomidine [RD] and ropivacaine clonidine [RC]) in a randomized, double-blind fashion...
