Objectives: Dexmedetomidine has been utilized as an adjuvant to prolong single local anaesthetic injection technique in brachial plexus block despite of adverse effects and cost-effectiveness. Morphine, a classic opioid, is also used as an adjuvant in neuraxial and perineural nerve blocks. In this study, we compared the effects of these two different adjuvants to ropivacaine in interscalene bra...

Interscalene brachial plexus block provides effective anesthesia and analgesia for shoulder surgery. One of the disadvantages of this technique is the risk of hemidiaphragmatic paresis, which can occur as a result of phrenic nerve block and can cause a decrease in the pulmonary function, limiting the use of the block in patients with reduced functional residual capacity or a preexisting pulmona...

BACKGROUND AND OBJECTIVES In this study, the aim was to compare postoperative analgesia effects of the administration of ultrasound-guided interscalene brachial plexus block and intra-articular bupivacaine carried out with bupivacaine. METHODS In the first group of patients 20 mL 0.25% bupivacaine and ultrasound-guided interscalene brachial plexus block (ISPB) were applied, while 20 mL 0.25% ...

PURPOSE Change in the landscape of medical education coupled with a paradigm shift toward outcome-based training mandates the trainee to demonstrate specific predefined performance benchmarks in order to progress through training. A valid and reliable assessment tool is a prerequisite for this process. The objective of this study was to characterize ultrasound-guided axillary brachial plexus bl...

Background and objectives The paraneural sheath is a multilayered network of collagen fibers that surround the brachial plexus. Currently, there are no sonographic data on plexus, which this study aimed to evaluate. Methods Ultrasound imaging datasets 100 patients who received costoclavicular plexus block, using high-definition ultrasound imaging, were retrospectively reviewed. Video files, rep...

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...

Anesthesia options for upper extremity surgery include general and regional anesthesia. Brachial plexus blockade has several advantages including decreased hemodynamic instability, avoidance of airway instrumentation, and intra-, as well as post-operative analgesia. Prior to the availability of ultrasound the risks of complications and failure of regional anesthesia made general anesthesia a mo...
