Braquial plexus

The brachial plexus block can be performed through several approaches. The recently described ultrasound-guided costoclavicular block at the costoclavicular space has gained popularity, presenting promising results for upper limb anaesthesia and postoperative analgesia. This block comes as an alternative to the traditional infraclavicular approach, with results suggesting improved block quality and reduced risk of complications. This article presents a narrative review of the literature and the current evidence available...

The costoclavicular brachial plexus block (CBPB) has been receiving increasing attention as an effective technique for upper arm surgery conducted without phrenic paralysis. However, studies in children are lacking. CBPB was applied to a 10 year-old girl undergoing scheduled radial and ulnar osteotomy due to multiple cartilaginous exostoses and ulnar lengthening. CBPB was performed with a bolus administration of 10 mL of 0.25% levobupivacaine, and the catheter was sequentially replaced in the right costoclavicular space...

INTRODUCTION: Shoulder dystocia is a nonpreventable obstetric emergency that causes severe complications, such as obstetric brachial plexus palsy. The objective of the study was to determine the incidence of obstetric brachial plexus palsy and other neonatal complications associated with shoulder dystocia in deliveries managed in a university hospital after the implementation of a simulation-based training that was offered to all the labour and delivery staff on a voluntary basis. MATERIAL AND METHODS: Retrospective observational study including all cases of shoulder dystocia and associated complications (mainly obstetric brachial plexus palsy) documented between January 2017 and December 2020, after the implementation of the training...

BACKGROUND: The cervical rib can be a rare finding in asymptomatic subjects. When it produces compression, it affects variably the vasculo-nervous structures of the brachial plexus; the clinical history is progressive. The imaging studies indicate the site of osteo-neuro-vascular conflict and electrophysiological studies indicate the degree of neural involvement. CASE REPORT: We present a patient with an eight-month history of paresis and right dysesthesias, with an image of bilateral cervical ribs with different anatomical characteristics...

The roadside hawk (Rupornis magnirostris) is a free-living bird that commonly has wing injuries caused by man-made obstacles when flying. Studies that describe the topographic anatomy of the wings of this species are necessary to assist in the treatment of possible wing lesions. For this reason, the present work aimed to describe the origin and insertion of the nerves that constitute the brachial plexus in roadside hawks. Five roadside hawk carcasses donated to the Animal Anatomy Laboratory of the São Judas University Center, UNIMONTE campus, by CEPTAS (Center for Research and Screening of Wild Animals) were used for the study...

Anesthetic management using costoclavicular brachial plexus block with patient-controlled analgesia in pediatrics: a case report Abstract The costoclavicular brachial plexus block (CBPB) has been receiving increasing attention as an effective technique for upper arm surgery conducted without phrenic paralysis. However, studies in children are lacking. CBPB was applied to a 10 year-old girl undergoing scheduled radial and ulnar osteotomy due to multiple cartilaginous exostoses and ulnar lengthening. CBPB was performed with a bolo administration of 10 mL of 0...

BACKGROUND: Brachial plexus block has become one of the most widely-used anaesthetic techniques in the world for upper limb anaesthesia. There are three different brachial blocks techniques: supraclavicular, infraclavicular and axillary block. However, its execution is not exempt from possible clinical complications, and it is not clear which of these is associated with a lower complication rate and greater anaesthetic success. MATERIALS AND METHODS: Systematic review and meta-analysis following the Cochrane and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to identify controlled clinical trials reporting the three techniques...

Brachial plexus lesions can significantly affect patient function. The type of management will depend on the severity of the injury as well as the anatomical location. Tendon transfers around the shoulder have emerged as an effective treatment alternative, and therefore we should consider them when faced with patients who might require it. There are various transfer techniques, within which the most frequently used are upper trapezium, latissimus dorsi and lower trapezium transfers, each with its specific indications and objectives depending on the type of patient...

BACKGROUND AND OBJECTIVES: In shoulder arthroscopy, on an outpatient basis, the patient needs a good control of the postoperative pain that can be achieved through regional blocks. Perineural dexamethasone may prolong the effect of these blocks. The aim of this study was to evaluate the effect of perineural dexamethasone on the prolongation of the sensory block in the postoperative period for arthroscopic shoulder surgery in outpatient setting. METHODS: After approval by the Research Ethics Committee and informed consent, patients undergoing arthroscopic shoulder surgery under general anesthesia and ultrasound-guided interscalene brachial plexus block were randomized into Group D – blockade performed with 30 mL of 0...

INTRODUCTION: Respiratory muscle function in the postoperative period is a key to whether a patient develops Postoperative Respiratory Failure (PRF) or not. PRF occurs when the gas exchange does not meet metabolic needs. Ipsilateral paralysis of the hemidiaphragm after interscalenic brachial plexus block (ISB) causes an acute reduction of respiratory muscle function. This reduction does not cause PRF when the contralateral hemidiaphragm generates enough gas exchange to meet metabolic demands...

OBJECTIVE: To evaluate the efficacy and safety of one single-session of radiofrequency ablation (RFA) performed in thyroid benign and predominantly solid nodules. PATIENTS AND METHOD: Unicentric retrospective study in usual clinical setting that included patients with solid and benign thyroid nodules treated with one single session of RFA and with folllow-up of at at least 6 months after the procedure. RFA was performed as an alternative to surgery in cases of pressure symptoms or nodular growth evidence...

The independent neurovascular anatomy of the long head of the triceps brachii and its suitability as a free muscle transfer have been extensively studied. Instead muscle transposition of the long head of the triceps brachii to enhance elbow flexion has been rarely described. We describe in this paper two cases of injury of brachial plexus sequel in which transposition was performed only on the long head of the triceps. The elbow flexion was improved, the extension was preserved.

Before diaphragm ultrasonography, assessment of diaphragm function was very difficult due to the complex nature of its exploration. The use of this new technique has shed light on diagnostic problems and treatment with an improvement in final outcomes for critically ill patients, in whom the incidence of diaphragm weakness or dysfunction has been underestimated. Better knowledge of diaphragm function enables us earlier diagnosis by quantification of diaphragm contractile activity or evaluation of functional status after delivery of plexus block anaesthesia, facilitating therapeutic decisions...

The authors report the clinical case of a 29 year-old caucasian male, previously healthy, victim of traffic accident with head and chest trauma, resulting in a prolonged stay (around 60 days) in an intensive care unit. After hospital discharge, the patient noticed a slow growing of a left supraclavicular pulsatile mass, associated with pain, both local and irradiating to the left arm. The diagnostic investigation revealed a complex false aneurysm with associated arterio-venous fistulae, dissecting cervical muscle planes and involving the braquial plexus...

INTRODUCTION: The nerve conduction studies, F-waves and dermatosomal and lor somatosensory evoked potential have a low level of sensitivity for Thoracic Outlet Compression Syndrome (TOCS) diagnosis. A standard negative electrodiagnostic study does not exclude the presence of TOCS. OBJECTIVE: The purpose of this neurophysiological note is that the Wright's hyperabduction, costoclavicular compression and Adson's scalenus tests important in making a clinical diagnosis of TOCS can be used as neurophysiological provocative maneuvers to determine the effect of braquial position on electrodiagnostic parameters...
