Filter by:The aim of the study is to investigate how the combination of ropivacaine (a slow onset, long duration local anesthetic) with lidocaine (a rapid onset, shorter duration local anesthetic) affects the onset and duration of a lateral infraclavicular plexus brachialis (LIC) block in patients undergoing non-acute hand surgery.
The aim of this study was to compare the efficacy of caudal block and sacral espb used as a postoperative analgesia method in urogenital pediatric surgery cases.
Background and rationale: Ultrasound-guided regional anesthesia is a widely used pain control method today. A critical aspect of the procedure is accurate visualization of anatomical structures on ultrasound to precisely define target areas. Distinguishing surrounding tissues with an imaging model that automatically recognizes sonoanatomy in ultrasound images will reduce unintended intraneural injections or injury to other anatomical structures in close proximity and increase patient safety. Research question; How can we improve the ultrasound images we frequently use in regional blocks by integrating them with artificial intelligence to reduce complications and improve applications? And what is the accuracy of the developed artificial intelligence support during imaging? Research purpose; This work; We aim to further increase the safety of different regional block positions, minimize the risk of complications, and improve ultrasound visualization by developing an artificial intelligence model (AI Model-Artificial Intelligence) that automatically identifies and segments anatomical landmarks, provides visual guidance for inexperienced colleagues, and improves the performance of the developed model during application. aims to demonstrate its accuracy. Hypothesis; Numerous studies have shown that the use of ultrasound and neurostimulators in practice increases the success, onset and quality of nerve blocks, but due to the low incidence of major complications and the absence of comparable randomized studies, no definitive statement can be made as to whether ultrasound reduces the overall rate of nerve damage. An imaging model that automatically marks sonoanatomy with artificial intelligence in ultrasound images can reduce unintended intraneural injections or injury to other anatomical structures in close proximity and improve patient safety.
Suprascapular nerve block is an injection method that has been shown to be effective in shoulder rehabilitation in diseases such as adhesive capsulitis and stroke .. Applying the block under USG guidance instead of blinding increases the effectiveness and reduces complications.
The goal of this randomized, double-blind, placebo-controlled, crossover study is to test the effectiveness of 10 kilohertz (kHz) high-frequency transcutaneous stimulation for tremor in people with Parkinson's disease. The main questions it aims to answer are: - Compare the effectiveness between sham stimulation and real stimulation (10kHz) for different types of tremors [rest tremor, postural tremor, kinetic tremor], fine motor skills, and maximal isometric handgrip strength. - Register adverse events, the blinding success of participants and evaluator, and subjective perception of tremor improvement. Participants will perform the following tasks in an "off" state (without levodopa and dopamine agonists medication). All of them were performed on the upper limb with more tremor. - Rest Tremor: Forearm on the armrest, count backward from 100 to 0 as fast as possible for 1 minute and 30 seconds. - Postural Tremor: Extend the arm parallel to the floor (90º shoulder flexion with the forearm extended) for 30 seconds. - Kinetic Tremor: Hold a cup by the handle, raise it close to the mouth for 3 seconds, then return to the initial position. - Fine Motor Skills: Complete the nine-hole peg test, placing pegs into holes as quickly as possible. - Handgrip Strength: Squeeze the device as strongly as possible for 3 seconds, then rest for 15 seconds.
Ultrasound-guided regional anesthesia/analgesia techniques (or simply, 'regional blocks') have gained popularity as they can reduce, and sometimes even eliminate, the need for opiate analgesics (and, consequently, their side effects), thereby improving patient safety, reducing length of hospital stay and medical costs, and improving patient satisfaction. However, a major barrier to mainstream uptake of such techniques relates to training. These techniques require the acquisition of new skills under expert guidance, which is often not possible given the daily demands placed upon anesthesiologists. As a result, many opportunities for providing regional blocks may be missed. The purpose of this study is to implement a new real-time 'near remote' guidance method in which trainees who are to perform regional blocks can do so via tele-mentoring under expert guidance. This will be done using a novel technology whereby the ultrasound image is concurrently displayed on an iPad screen (for the block operator/trainee) as well as on the (near remotely supervising) expert mentor's smartphone. Trainees and mentors will use this method to perform various standard of care regional blocks, either in the perioperative or emergency department settings. Participants' opinions of the novel teaching and learning method will be assessed.
Shoulder surgery can be very painful surgery after which the use of opioids is often required. The well-known side-effects of opioids (e.g. respiratory depression, somnolence, nausea, vomiting, and pruritus) limit their use in so called 'fast track' surgery and anaesthesia programmes. the study aimed to compare the effect of sub omohyoid suprascapular nerve block versus interscalene nerve block in preventing postoperative pain and decreasing analgesic consumption in patients scheduled for shoulder surgery
Ultrasound-guided suprazygomatic maxillary nerve block (SMNB) will be performed in paediatric patients with or without the aid of ultrasound guidance. Magnetic resonance imaging (MRI) is used to visualize the spread of the local anaesthetic (LA) spread after suprazygomatic injection and to verify LA contact with the maxillary nerve in the pterygopalatine fossa (PPF).
The patients were divided into two groups by random number method: GroupRD1 group and GroupRD2 group were given general anesthesia and intercostal nerve block.The drug for intercostal nerve block was 0.33% ropivacaine +2.333mg compound betamethasone (1.667mg betamethasone dipropionate + 0.667mg betamethasone sodium phosphate) to 15ml.
After thoracoscopic surgery, patients still face moderate to severe pain. How to effectively control pain and promote postoperative recovery of patients is a challenging problem. Thoracic paraspinal block is effective in controlling pain after thoracoscopic surgery, but it also carries the risk of difficulty in operation and puncture of the pleura. In recent years, erector spinal plane block and serratus anterior plane block have been used for postoperative analgesia after thoracoscopic surgery. The purpose of this study was to explore whether erector spinal plane combined with serratus anterior plane block can replace thoracic paravertebral block and provide a more complete analgesia after thoracoscopic surgery. Therefore, this study is of great clinical significance.
