BACKGROUND: The effect of interscalene block (ISB) on pulmonary function of obese participants has not been investigated. The goal of this study is to assess the association of obesity (body mass index [BMI] >29 kg/m vs BMI <25 kg/m) and change in forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) after ISB in participants undergoing outpatient shoulder surgery. METHODS: This prospective, observational cohort study compared obese (BMI >29 kg/m) and normal-weight (BMI <25 kg/m) groups undergoing ISB for ambulatory shoulder surgery, on preblock and postblock FVC and FEV1, at 30 minutes postblock and in the postanesthesia care unit (PACU)...

We evaluated whether pre-emptive analgesia with a pre-operative ultrasound-guided infraclavicular brachial plexus block resulted in better postoperative analgesia than an identical block performed postoperatively. Fifty-two patients undergoing fixation of a fractured radius were included. All patients received general anaesthesia with remifentanil and propofol. Patients were randomly allocated into two groups: a pre-operative block or a postoperative block with 0.5 ml.kg(-1) ropivacaine 0.75%. After surgery, all patients received regular paracetamol plus opioids for breakthrough pain...

In our hospital, we introduced a system to measure the collective and individual efficacy of brachial plexus and popliteal nerve blocks with the objective to create transparency as an instrument for monitoring and improvement. Initially, individual results were anonymous, but after 1 year anonymity was lifted within the team of anesthesiologists and results are now discussed quarterly. Collective performance of interscalene, supraclavicular, and popliteal blocks improved significantly over time. Sharing and discussing collective and individual performance has resulted in critical self-appraisal and increased willingness to learn from each other and strengthened the team's ambition for further improvement...

INTRODUCTION: The effect of adding dexmedetomidine (α2-adrenoceptor agonist) to local anaesthetics in brachial plexus blocks has been evaluated, however there has been no consensus regarding the ideal dose of dexmedetomidine. Without ultrasound axillary block has been considered as the safest approach for brachial block. AIM: To evaluate the efficacy of two doses of dexmedetomidine (0.5 μg/kg and 1 μg/kg) as an adjuvant to lignocaine in patients undergoing forearm surgeries under axillary brachial plexus block...

We present the case of a 38-year-old man undergoing surgical repair of his pectoralis major tendon. An interscalene catheter was placed between the middle and lower trunks of the brachial plexus. Postoperatively, ropivacaine 0.2% was infused through postoperative day. The patient had excellent pain control requiring minimal opioid analgesics. A catheter between the middle and lower trunks of the brachial plexus provided excellent postoperative analgesia after pectoralis major tendon reinsertion. Additionally, the block likely protected the surgical repair during emergence from anesthesia and in the early postoperative period by providing a motor block of the pectoralis major muscle...

BACKGROUND: Clonidine, an α-2 agonist, has long been used as a local anesthetic adjunct with proven efficacy to prolong peripheral nerve block duration. Dexmedetomidine, a newer α-2 agonist, has a more favorable pharmacodynamic and safety profile; however, data comparing its efficacy as an adjunct to that of clonidine are inconsistent. We sought to compare the clinical efficacy of these 2 α-2 agonists by examining their effects on peripheral nerve block characteristics for upper extremity surgery...

BACKGROUND: Few studies were performed to compare ultrasound guided brachial plexus block with procedural sedation for reduction of shoulder dislocations in the Emergency Department (ED). This study was done to provide further evidence regarding this comparison. METHODS: This was a randomized clinical trial performed on patients presenting with anterior shoulder dislocations to the emergency department of an academic level 2 trauma center. Exclusion criteria were any contraindications to the drugs used, any patient which may not be potentially assigned into both groups because of an underlying medical condition, presence of neurovascular compromise related to the dislocation, presence of concomitant fractures, and patient refusal to participate in the study...

PURPOSE: This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared to the coracoid approach. METHODS: A total of 100 adult patients who received IBPB block for upper limb surgery were randomized into two groups: a coracoid approach group (group C) and a retroclavicular approach group (group R)...

Background.: The incidence of hemidiaphragmatic paresis with continuous interscalene brachial plexus block (CISB) can approach 100%. We tested the hypothesis that extrafascial placement of the catheter tip reduces the rate of hemidiaphragmatic paresis compared with intrafascial tip placement for CISB while providing effective analgesia. Methods.: Seventy patients undergoing elective major shoulder surgery under general anaesthesia were randomized to receive an ultrasound-guided CISB plexus block for analgesia with the catheter tip placed either within (intrafascial group) or immediately outside (extrafascial group) the brachial plexus sheath midway between the levels of C5 and C6...
