conclusions preemptive clonidine has many marvelous advantages over midazolam, including better sedation inside the operating room and then in the post-operative care unit, lower fentanyl doses are required during surgery, more stable heart rate and blood pressure are observed during the procedure, and patients report lower post-operative pain scores. objectives to compare the effect of preempt...

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...

Effective brachial plexus blockade requires a thorough understanding of the anatomy of the plexus, as well as an appreciation of anatomic variations that may occur. This review summarizes relevant anatomy of the plexus, along with variations and anomalies that may affect nerve blocks conducted at these levels. The Medline, Cochrane Library, and PubMed electronic databases were searched in order...

introduction: median nerve (mn), one of terminal branches of brachial plexus, is commonly associated with several variations. this research aimed to review the literature related to the variations of mn from axillary region to cubital fossa. methods: we searched google scholar, science direct, springer, and pubmed electronic databases to compile reports related to the variation of mn published ...

Bilateral brachial plexus blocks and regional anesthesia in trauma patients are rarely performed due to potential complications when using these techniques. We illustrate a case in which bilateral infraclavicular nerve blocks were placed as part of a multimodal approach to pain management in a trauma patient. We discuss potential hazards, important considerations, and rationale for attempting t...

atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...

BACKGROUND Current techniques of brachial plexus block are "blind," and nerve localization can be frustrating and time consuming. Previous studies on ultrasound-assisted brachial plexus blocks are mostly performed with scanning probes of 10 MHz or less. The authors tested the usefulness of a state-of-the-art, high-resolution ultrasound probe (up to 12 MHz) in identifying the brachial plexus in ...

STUDY OBJECTIVE To determine if the use of ultrasound guidance (vs non-ultrasound techniques) improves the success rate of nerve blocks. DESIGN Meta-analysis of randomized controlled trials (RCTs) in the published literature. SETTING University medical center. MEASUREMENTS 16 RCTs of patients undergoing elective surgical procedures were studied. Patients underwent ultrasound-guided or non...
