non alkalinized and alkalinized 2 chloroprocainevs lidocaine for Intravenous Regional Anesthesia during outpatient hand surgery
Canadian Journal of Anaesthesia-journal Canadien D Anesthesie, 1999Co-Authors: Patrick A Lavin, Cynthia Henderson, Himat VaghadiaAbstract:Purpose Chloroprocaine should be an ideal agent for Intravenous Regional Anesthesia (IVRA) because of its rapid onset and ester hydrolysis. Raising the pH of local anesthetics may increase the speed of onset and the intensity of nerve blocks. We compared plain and alkalinized 2-chloroprocaine 0.5% with lidocaine for IVRA.

tourniquet deflation prior to 20 minutes in upper extremity Intravenous Regional Anesthesia
Hand, 2018Co-Authors: Richard W Gurich, Justin W Langan, Robert J Teasdall, Stephanie L Tanner, John L SandersAbstract:BACKGROUND: Bier blocks, or Intravenous Regional Anesthesia (IVRA), are a method of Anesthesia for upper extremity surgeries. This study reports our experience with tourniquet deflation prior to 20 minutes with upper extremity IVRA. METHODS: This study was designed as a retrospective cohort analysis. Records, including intraoperative and immediate postoperative Anesthesia notes, of 430 patients who underwent IVRA with an upper extremity Bier block and a corresponding tourniquet time of less than 20 minutes were reviewed. Patient demographics, procedure(s) performed, American Society of Anesthesiologists scores, volume of lidocaine used in Bier block, tourniquet time, and any complications were recorded. RESULTS: This cohort consisted of 127 males and 303 females. The 3 most common procedures performed were carpal tunnel release (315), trigger finger release (47), and excision of masses (34). The average tourniquet time for this cohort was 16 minutes (range, 9-19 minutes), and the average volume of lidocaine (0.5% plain) injected was 44 mL (range, 30-70 mL). A tourniquet time of 17 minutes or less was observed in 339 patients, and 170 patients had tourniquet times of 15 minutes or less. Five complications were recorded: intraoperative vomiting, mild postoperative nausea/vomiting, severe postoperative nausea and vomiting, and transient postoperative hypotension that responded to a fluid bolus. CONCLUSIONS: No major complications were observed in our cohort of upper extremity IVRA and tourniquet times of less than 20 minutes. Several variables play a role in the safety of upper extremity IVRA.

a north american survey of Intravenous Regional Anesthesia
Anesthesia & Analgesia, 1997Co-Authors: Cynthia Henderson, Brian C Warriner, James A Mcewen, Pamela M MerrickAbstract:One thousand questionnaires concerning the techniques and complications of Intravenous Regional Anesthesia (IVRA) were sent to 900 American and 100 Canadian anesthesiologists.Of the 321 respondents, 86% perform IVRA regularly. A wide variation in devicerelated and clinical aspects was found, ranging

subcutaneous local Anesthesia versus Intravenous Regional Anesthesia for endoscopic carpal tunnel release a randomized controlled trial
Journal of Neurosurgery, 2011Co-Authors: A Nabhan, W I Steudel, Lutfi Dedeman, Jehad Alkhayat, Basem IshakAbstract:Object This study compares the effectiveness of subcutaneous infiltration of a local anesthetic agent (LA) versus Intravenous Regional Anesthesia (IVRA) during endoscopic carpal tunnel release. Methods Forty-four patients suffering from severe symptoms restricting normal daily activities—such as persistent loss of feeling in the fingers or hand, or no strength in the thumb in spite of prolonged nonsurgical treatment—and with electromyographically proven carpal tunnel syndrome were enrolled in this study. All underwent endoscopic carpal tunnel release. Twenty-two patients had an endoscopic release of the median nerve under LA (LA Group). The other 22 patients underwent the surgery after Intravenous induction of Regional Anesthesia (IVRA Group). The operating room in-out time and tourniquet time were evaluated in both groups. The patients were also asked to evaluate the pain associated with the tourniquet during surgery using a visual analog scale. The Michigan Hand Outcomes Questionnaire was used to assess...

clonidine versus ketamine to prevent tourniquet pain during Intravenous Regional Anesthesia with lidocaine
Regional Anesthesia and Pain Medicine, 2001Co-Authors: N Gorgias, P Maidatsi, Anastasios M Kyriakidis, K Karakoulas, Demetrios N Alvanos, M GialaAbstract:Background and Objectives Both clonidine and ketamine have been found to prolong the action of local anesthetics through a peripheral mechanism. Our study compares the efficacy of a low dose of clonidine or ketamine separately added to Intravenous Regional Anesthesia (IVRA) with lidocaine to prevent tourniquet pain. Methods We conducted a prospective randomized double-blinded study in 45 patients undergoing hand or forearm surgery, with anticipated duration exceeding 1 hour under IVRA. Proximal cuff inflation of a double tourniquet was followed by administration of 40 mL of lidocaine 0.5% and either saline, 1 μg/kg clonidine, or 0.1 mg/kg ketamine. When Anesthesia was established, the inflation of the proximal and distal cuff was interchanged. Thereafter, tourniquet pain was rated on a visual analog scale (VAS) every 10 minutes. Intraoperatively, boluses of 25 μg fentanyl were provided for tourniquet pain treatment when required, and total fentanyl consumption was recorded. Results Patients receiving plain lidocaine persistently reported the highest pain scores among groups (P Conclusions The addition of clonidine 1 μg/kg or ketamine 0.1 mg/kg to lidocaine for IVRA delays the onset of unbearable tourniquet pain and decreases analgesic consumption for tourniquet pain relief, although ketamine has a more potent effect.
