BACKGROUND: Landmark and ultrasound-guided transversus abdominis plane blocks have demonstrated an opioid-sparing effect postoperatively after cesarean delivery. The more posterior quadratus lumborum (QL) might provide superior local anesthetic spread to the thoracolumbar fascia paravertebral space. aim of our study was evaluate efficacy QL block METHODS: A randomized, double-blind, controlled trial performed. Forty parturients undergoing delivery received bilateral with either 2 mg/mL...
Ultrasound guidance is frequently used to perform infraclavicular brachial plexus blocks. In this study, we compared electrical nerve stimulation and ultrasound for the lateral sagittal block.Eighty patients, ASA 1-2, were randomized either (group NS) or ultrasound-guided blocks US). The was anesthetized with 0.6 mL/kg mepivacaine (15 mg/mL) epinephrine (2.5 microg/mL) in both groups. For blocks, local anesthetic injected cranioposterior axillary artery. An observer who blinded method...
The Shamrock technique is a new method for ultrasound-guided lumbar plexus blockade. Data on the optimal local anaesthetic dose are not available.The objective of this study to estimate effective ropivacaine 0.5% block.A prospective dose-finding using Dixon's up-and-down sequential method.University Hospital Orthopaedic Anaesthesia Unit.Shamrock block performance and assessment were scheduled preoperatively. Ropivacaine was titrated with Dixon Massey stepwise change 5 ml in each consecutive...
Inconsistent nomenclature and anatomical descriptions of regional anesthetic techniques hinder scientific communication engender confusion; this in turn has implications for research, education clinical implementation anesthesia. Having produced standardized abdominal wall, paraspinal chest wall techniques, we aimed to similarly do so upper lower limb peripheral nerve blocks.
Infraclavicular techniques are often used to perform brachial plexus blocks. In our volunteer study we magnetic resonance imaging identify the and axillary vessels in a sagittal plane corresponding lateral infraclavicular block. 20 volunteers, all cords were positioned within 2 cm from artery approximately 2/3 of circle. We derived an injection site that was closest cords, cranio-posterior adjacent artery. conclude this knowledge may be useful for performance blocks aided by ultrasound....
( Anesth Analg. 2018;126:559–565) Ultrasound (US)-guided transversus abdominis plane (TAP) blocks, although widely used for postoperative analgesia in inferior abdominal wall incision surgeries, are known to provide when compared neuraxial morphine and other multimodal regimens. A modified quadratus lumborum (QL) block technique, with injection at the posterior border of QL muscle, may better longer lasting US-guided anterior TAP blocks. The authors present study evaluated postcesarean...
In Brief BACKGROUND: Understanding the mechanisms causing variation in current thresholds for electrical nerve stimulation may improve safety and success rate of peripheral blocks. Electrical impedance tissue surrounding a affect response to stimulation. this volunteer study, we investigated relationship between threshold needed obtain neuromuscular response. METHODS: measurements were performed median axilla at elbow 29 volunteers. The needletip was positioned distance 5, 2.5, 0 mm from as...
Background Maxillary nerve blocks are often used as part of a multimodal postoperative pain management regimen for children undergoing cleft palate surgery. It has not been demonstrated yet that ultrasound guidance provides superior local anesthetic distribution and better success rates compared with the landmark-based block technique. The aim study was to compare effect suprazygomatic maxillary on spread pterygopalatine fossa. Methods 20 pediatric patients scheduled repair received...
Electrical nerve stimulation is commonly used to perform peripheral blocks. The purpose of this study was investigate the relation between stimulating currents and distance needle-tip stimulated nerves.In 18 volunteers radial ulnar nerves were in elbow region from opposite directions. Needle-to-nerve distances measured by high-frequency ultrasound when motor responses electrical elicited with 5, 2, 1 0.5 mA impulse widths 0.1 ms. Additionally, current thresholds for identified contact...
Background The Onvision needle tip tracking (NTT) is a new technology consisting of with an ultrasound sensor close to the and console for computerised signal processing. aim study was evaluate NTT during ultrasound‐guided simulated peripheral nerve block procedures in porcine phantom model. Methods Forty anaesthesiologists performed in‐plane out‐of‐plane blocks without guidance. primary outcome measure procedure time. Secondary outcomes were hand movements path length travelled by hands...
Electrical impedance measurements have been used to detect intraneural needle placement, but there is still a lack of precision with this method. The purpose the study was develop method for discrimination nerve tissue from other types based on multiple frequency measurements. Impedance 25 different frequencies between 1.26 and 398 kHz were obtained in eight pigs while placing tip stimulation within sciatic tissues. Various variables measurement tested discrimination. Best by using three...
Summary We evaluated whether pre‐emptive analgesia with a pre‐operative ultrasound‐guided infraclavicular brachial plexus block resulted in better postoperative than an identical performed postoperatively. Fifty‐two patients undergoing fixation of fractured radius were included. All received general anaesthesia remifentanil and propofol. Patients randomly allocated into two groups: or 0.5 ml.kg −1 ropivacaine 0.75%. After surgery, all regular paracetamol plus opioids for breakthrough pain....
