it has been sugeested since long that peripheral nerves possess opiod receptors and this has tempted clinicans in adding narcotics to local anesthetics to prolong the analgesic effects of these solutions. in this regard, we studied 45 patients undergoing surgical procedures on upper extremities. the patients scheduled for surgery were divided in to three groups, each comprising of 15 patients a...

Background: Various drugs are used as adjuvants to improve the quality of supraclavicular block. Objective: This study aimed to investigate the effect of adding dexmedetomidine to lidocaine on the characteristics of supraclavicular block in upper limb surgeries. Methods: This double-blind controlled clinical trial was conducted on patients undergoing upper extremity fracture surgery under a ...

BACKGROUND A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. METHODS One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The infraclavicular brachial plexus ...

Introduction: There are different methods to perform brachial plexus block. Interscalene and supraclavicular approaches are the most frequently used technique during upper limb surgeries.The aims of this study were to compare the onset and duration of sensory and motor block, hemodynamic parameters, sparing of analgesia in any dermatome and to observe any adverse effect during lower arm, elbow ...

UNLABELLED In this prospective study, we assessed the quality, safety, and execution time of supraclavicular block of the brachial plexus using ultrasonic guidance and neurostimulation compared with a supraclavicular technique that used anatomical landmarks and neurostimulation. It was hypothesized that ultrasonic guidance would increase the proportion of successful blocks, decrease block execu...

Ultrasound guided regional anaesthesia is becoming increasingly popular. The supraclavicular block has been transformed by ultrasound guidance into a potentially safe superficial block. We reviewed the techniques of performing supraclavicular block with special focus on ultrasound guidance.

Supraclavicular brachial plexus block is a common anesthetic technique performed for surgery of the upper extremities. We experienced a case of acute hypercapnic respiratory distress with loss of consciousness during creation of an arteriovenous fistula under ultrasound-guided supraclavicular brachial plexus block using 30 mL of 0.75 % ropivacaine. We detected ipsilateral hemidiaphragmatic para...

A comparative study between anatomical landmark and nerve stimulator guided supraclavicular brachial plexus block for neurovascular variations in topographic anatomy of brachial plexus. In the backdrop of our country, nerve stimulator is still not available in many centres and many anesthetists do not yet have the proper expertise and experience in giving nerve stimulator guided brachial plexus...

Objectives: Ultrasound-guided supraclavicular and infraclavicular blocks are commonly used for upper extremity surgery. The primary aims of our study were to compare block success, block onset times and performance times; secondary aims were to compare the number of needle advancements, and incidence of adverse events of ultrasound-guided supraclavicular or infraclavicular blocks. Methods: 110 ...
