Lesions of single nerves

2017

The trigeminal nerve exits the brain in its anatomical course in the area of the pons and proceeds to the anterior edge of the petrous bone. There, the nerve forms the trigeminal ganglion – also known as the Gasserian ganglion – which, sheathed by a dural sleeve, gives off three branches (V1–3).

Video-assisted two-stage basilic vein transposition for creation of brachio-basilic arteriovenous fistulae

2012

We report our experience in a mixed minimally-in- vasive technique for the two-stage transposition of basilic vein on a small series of eight patients. The operative tech- nique consisted of a modified endoscopic (1) approach for the two-stage transposition (2). The intervention was performed under Brachial Plexus Block (3).

Efficacy of vertical infraclavicular plexus block vs. modified axillary plexus block: a prospective, randomized, observer-blinded study.

2005

Background:  Despite containing severe risks, infraclavicular approaches to the brachial plexus gained increasing popularity. Likewise, the vertical infraclavicular plexus block improved anesthesia compared to the standard axillary approach but contains the risk of pneumothorax. Therefore we modified the standard axillary technique by inserting a proximal directed catheter, referred to as a high axillary plexus block. We prospectively compared quality and onset of neural blockade after vertical infraclavicular plexus block (VIP) and high axillary plexus block (HAP) in two randomized groups (30 patients in each). Methods:  In group VIP the insulated needle was inserted midway between the ven…

157 Patient satisfaction and safety of sedation using perineurial dexmedetomidine in axillary brachial plexus block for wrist surgery

2021

Background and Aims Dexmedetomidine is known to prolong the duration of regional block while its sedative effect when administered perineurally is unknown.[1] We aim to evaluate the effect of perineural Dexmedetomidine on the systemic sedation in patients after axillary brachial plexus block (ABPB). Methods This prospective randomized control trial includes 78 patients undergoing wrist surgery receiving ABPB. The study was conducted with the approval of Ethics Committee of Riga Stradins University. Patients were randomized into two groups – control (CG) (N=39) and study group (SG) (N=39). Both groups received ABPB with a standard dose of local anaesthetics. The study group also received 100…

Maturation of near-field and far-field somatosensory evoked potentials after median nerve stimulation in children under 4 years of age

2000

Abstract Objectives : The maturation of subcortical SEPs in young children. Methods : Median nerve SEPs were recorded during sleep in 42 subjects aged 0–48 months. Active electrodes were at the ipsilateral Erb's point, the lower and upper dorsal neck, and the frontal and contralateral centroparietal scalp; reference electrodes were at the contralateral Erb's point, the ipsilateral earlobe and the frontal scalp; bandpass was 10–3000 Hz. The peaks were labelled by their latencies in adults. Results : The peak latencies of N9 (brachial plexus potential) decreased exponentially with age during the first year, but increased with height thereafter. The interpeak latencies (IPLs) N9–N11, which mea…

High volume and low concentration of anaesthetic solution in the perivascular interscalene sheath determines quality of block and incidence of compli…

2006

Background and objective: In the perivascular sheath of the brachial plexus, the volume of anaesthetic solution determines the quality of anaesthetic cover. Fibrous septa may divide the perivascular space into compartments, leading to inadequate diffusion of the anaesthetic solution. The aim of our study was to obtain good anaesthesia and less complications using high volume of low concentration anaesthetic solution, overcoming the obstacle of the septa with a double approach to the scalene sheath. Methods: Sixty patients scheduled for shoulder capsuloplasty received both Winnie interscalene brachial plexus block and Pippa proximal cranial needle approach. The patients were randomly assigne…

Ultrasound observation of tissue fluid infiltration causing stridor in a woman undergoing shoulder arthroscopy

2012

Respiratory stridor developed rapidly during an interscalene brachial plexus block for shoulder arthroscopy in an obese woman. Extensive cervicothoracic edema due to tissue diffusion of the arthroscopic fluid was suspected. The outcome of patient after conservative management was satisfactory. We give a brief review of how this complication develops, the ultrasound findings, and briefly discuss similar cases.

Functional outcomes of peripheral nerve repair and regeneration: clinical and experimental study

This study investigated pre- and post-operative evaluation of peripheral nerve injuries and functional outcomes of peripheral nerve regeneration after different type of injuries and different type of treatments. Neuromas/scar neuritis and brachial plexus injuries are specifically addressed; literature and experimental evidence on the outcomes of vascularized nerve grafts are presented.
