Brachial plexus block is a frequently used technique for upper extremity surgery. All present approaches and techniques have certain advantages and disadvantages. It's necessary to develop a new approach to brachial plexus block which 1) provides reliable anesthesia, 2) is easy to perform, 3) isn't restricted by posture, 4) provides extensive sensory distribution, 5) causes as few complications as possible, 6) easily place a secured catheter for post-operative analgesia. The investigators established the retrograde infraclavicular brachial plexus block approach. The investigators compared and verified the feasibility, efficacy and safety of this new approach with other classic approaches to brachial plexus block.
Traditional brachial plexus block approaches have certain limitations. This study evaluated the effectiveness, safety and feasibility of a new retrograde infraclavicular brachial plexus block as compared with interscalene and supraclavicular approaches. 90 patients scheduled for elective upper limb surgery were recruited and randomized into three groups, 30 for each group. Patients of Group A received retrograde infraclavicular block, interscalene (by Winnie) approach for Group B and supraclavicular (by Kulenkampff) approach for Group C. The retrograde infraclavicular block was performed with the insertion point medial to the coracoid process and the needle advanced to ipsilateral interscalene groove. Neurostimulation was used and 40ml of 0.5% ropivacaine were injected. Sensory block, adverse effects and complications were evaluated and recorded every 5 minutes until 30min after local anesthetic injection. The needle insertion depth, angles in coronary and sagittal planes of Group A were also recorded. Success rate of each nerve sensory block, sensory block result, complications, rate of satisfaction, rate of failure and incidence rate of adverse effects are all compared among groups.

This study aims to detect differences in onset time of brachial plexus (i.e., arm) anesthesia using two different nerve block techniques. Using ultrasound guidance, axillary (i.e., at the...
Effective post-operative pain control can reduce patient morbidity and affect the patient outcome. Brachial plexus block is one of them, a popular and widely employed regional nerve block ...
The investigators plan to determine the onset time and incidence of hemidiaphragmatic paresis (HDP) with a double injection supraclavicular nerve block in patients presenting for upper ext...
Brachial plexus blocks have some advantages, but also have some disadvantages as well. As with all nerve blocks, having to wait sometime for an effective block, sometimes failure to achiev...
We propose to compare the effects of local anaesthetic dilution on the characteristics of the ultrasound guided axillary brachial plexus block. Administration of 40ml lidocaine 1% with ep...
Dexmedetomidine, an alpha 2 receptor agonist, prolongs nerve block duration when administered in conjunction with peripheral nerve blocks. We hypothesised that sedation with dexmedetomidine could also...
We recently showed that the novel combination of a superficial cervical plexus block, a suprascapular nerve block, and the lateral sagittal infraclavicular brachial plexus block (LSIB) provides an alt...
Breast innervation consists of intercostal nerves and brachial plexus. Here we propose a technique to execute breast surgery without general anesthesia using erector spinae plane (ESP) block and selec...
To evaluate the effect of dexmedetomidine combined with ropivacaine on brachial plexus block in patients scheduled for elective shoulder arthroscopy.
The perineural administration of alcohol or phenol results in protein denaturation and, consequently, neurolysis. This can produce long-lasting analgesia, with a duration of 3-6 months. Although neuro...
The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.
A syndrome associated with inflammation of the BRACHIAL PLEXUS. Clinical features include severe pain in the shoulder region which may be accompanied by MUSCLE WEAKNESS and loss of sensation in the upper extremity. This condition may be associated with VIRUS DISEASES; IMMUNIZATION; SURGERY; heroin use (see HEROIN DEPENDENCE); and other conditions. The term brachial neuralgia generally refers to pain associated with brachial plexus injury. (From Adams et al., Principles of Neurology, 6th ed, pp1355-6)
A blocking of NEURAL CONDUCTION in the network of nerve fibers innervating the UPPER EXTREMITY.
Diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the BRACHIAL PLEXUS. Clinical manifestations include regional pain, PARESTHESIA; MUSCLE WEAKNESS, and decreased sensation (HYPESTHESIA) in the upper extremity. These disorders may be associated with trauma (including BIRTH INJURIES); THORACIC OUTLET SYNDROME; NEOPLASMS; NEURITIS; RADIOTHERAPY; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp1351-2)
A condition associated with compression of the BRACHIAL PLEXUS; SUBCLAVIAN ARTERY; and SUBCLAVIAN VEIN at the thoracic outlet and caused by a complete or incomplete anomalous CERVICAL RIB or fascial band connecting the tip of a cervical rib with the first thoracic rib. Clinical manifestations may include pain in the neck and shoulder which radiates into the upper extremity, PARESIS or PARALYSIS of brachial plexus innervated muscles; sensory loss; PARESTHESIAS; ISCHEMIA; and EDEMA.

Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
