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 goal of this clinical trial is to investigate the effectiveness of photoplethysmographic amplitude in assessing the extent of anesthesia in the 8th cervical dermatome in patients undergoing interscalene brachial plexus block (ISBPB). The main question it aims to answer is - Is there any difference in the post-block changes in photoplethysmographic amplitude measured from the ipsilateral 5th finger (supplied by the 8th cervical nerve root) between ISBPBs targeting the C5-to-C6 nerve roots and the C5-to-C8 nerve roots? - Do the changes in photoplethysmographic amplitude represent the extent of anesthesia in the 8th cervical dermatome? Participants will receive either ISBPB targeting the C5-to-C6 nerve roots or the C5-to-C8 nerve roots, and then the changes in photoplethysmographic amplitude will be measured from the 5th finger ipsilateral to ISBPB.
This study compares the analgesic efficacy of supraclavicular brachial plexus nerve block to axillary nerve block techniques in adults undergoing AV fistula creation. Both these techniques will be done under ultrasound guidance, using the same local anesthetic drug. 120 patients will be included in this study, 60 patients for each technique. This study will help us know better regional anesthesia techniques, the additional need for analgesia/anesthesia, and the recovery rate following either of the blocks for AV fistula surgery. An interim analysis will be done after recruiting 50% of cases (30 cases) in both arms.
Brachial plexus block is used for upper limb surgery. Local anesthesia alone for brachial plexus block provides good operative conditions, but have short duration of postoperative analgesia. Hence, various adjuvants to local anaesthetic agents to prolong the duration of peripheral nerve, analgesia. However, results are either inconclusive or associated with side effects. The purpose of this study is to determine whether dexmedetomidine as an adjuvant to ropivacaine in brachial plexus block improve quality of block in terms of duration of post operative analgesia.
The goal of this study is to compare the continuous brachial plexus block with or without intravenous patient controlled analgesia(PCA) in patients undergoing arthroscopic rotator cuff repair, in terms of quality of recovery, postoperative pain score, and adverse event.
A total of 120 patients (American Society of Anesthesiologist Physical Status 1-3) who signed a consent form among patients aged 19-80 years who are scheduled to undergo brachial plexus block and upper extremity surgery under monitored anesthetic care at our hospital were enrolled. Recruited patients are divided into three groups through computer-generated randomization by using the patient identification number assigned during patient recruitment. (40 people in each group) Standard monitoring is performed when the patient arrives at the operating room. Patients receive oxygen at 5-6 L/min using a simple facial mask, and receive a brachial plexus block under ultrasound guidance. After confirming the success of brachial plexus block, administration of propofol, remimazolam, or dexmedetomidine is started according to the assigned group. Assess the patient's level of consciousness through the MOAA/S (modified observer's assessment of alertness/sedation scale) scale. The drug injection ends when the skin suture is started after the main procedure. The time from the end of injection of each drug until MOAA/S becomes 5 points is measured. After the patient is transferred to the recovery room, the Aldrete score is assessed. The recovery profile, perioperative hemodynamic change, desaturation event, block duration, patient movement during surgery, patient satisfaction, and surgeon's satisfaction were investigated and analyzed for comparison.
The study aims to show the effects of interscalene brachial plexus (ISBP) block on intracranial pressure by measuring optic nerve sheath diameter (ONSD) and internal vein collapsibility index (IJV-CI).
Comparative Study Between Ketamine-Bupivacaine Versus Bupivacaine With Intravenous Ketamine Infusion In Supraclavicular Brachial Plexus Block During Upper limb Surgeries The techniques of regional anesthesia have become very popular as they provide several advantages in comparison with general anesthesia and systemic analgesia. They provide perfect pain control, decreased complications and reduced post-anesthesia care unit stay. Regional anesthesia provides more patient safety and better outcomes, which leads to the fact that ultrasound-guided regional anesthesia became more popular. Ultrasound provides clinicians with real-time images which are useful for better identification of the anatomical structures, safe needle placement and adequate local anesthetic spread. Brachial plexus blocks are commonly achieved via an interscalene, supraclavicular, infraclavicular or axillary approach. The supraclavicular level is an ideal site to achieve anesthesia of the entire upper extremity just distal to the shoulder as the plexus remains relatively tightly packed at this level, resulting in a rapid and high-quality block. For this reason, the supraclavicular block is often called the ''spinal of the arm'' Using the local anesthetics alone for supraclavicular brachial plexus block provide good operative conditions but have the disadvantage of shorter duration of postoperative analgesia. Various adjuvants such as opioids, dexmedetomidine, dexamethasone, midazolam, ketamine, etc., were added to local anesthetics in brachial plexus block to achieve quick and prolonged block. Ketamine is a noncompetitive antagonist of the N-methyl-D aspartate receptor(NMDAR). It is used as a premedication, and for sedation, induction and maintenance of general anesthesia. Local anesthetic and analgesic properties have been reported for ketamine. Intravenous administration of low-dose ketamine decreases postoperative opioid use and improves analgesia. Ketamine has been added to bupivacaine to prolong the duration of regional anesthesia and postoperative analgesia.
In this study investigators will compare two different approaches of brachial plexus block ;supraclavicular approach and retroclavicular approach regarding success rate, duration of block, complications
This study aims to assess analgesia efficacy between liposomal bupivacaine single injection interscalene blockade vs. continuous interscalene nerve block for patients undergoing primary total shoulder arthroplasty.
