Background: Opioids added to local anesthetics for peripheral nerve blocks may intensify analgesia and prolong analgesic and sensorial block duration. These agents may also cause potentiation and prolongation of motor block. Objective: This study compared the postoperative effects of 30 mL of 0.25% bupivacaine +50 mcg fentanyl and 30 mL of 0.25% bupivaca...

We studied 126 patients undergoing elective hip surgery; they received 20 ml of 0.5%, 0.75%, 1.0% ropivacaine or 0.5% bupivacaine extradurally in a double-blind design. Sensory block (pinprick), motor block (modified Bromage scale), quality of analgesia and neuromuscular block were assessed intermittently. Heart rate and arterial pressure were measured at regular intervals. A total of 115 patie...

aim and background:   intravenous regional anesthesia is easy to administer, reliable, and costeffective methods and materials:   in a randomized, double blinded, clinical trial thirty patients of 18 to 60 findings:   sensory block onset time, motor block onset time, tourniquet pain and analgesic conclusions:   addition of nitroglycerine to lidocaine to intravenous regional anesthesia can

normal 0 false false false en-us x-none ar-sa background: it was aimed to compare the efficacy and adverse effects of levobupivacaine alone and in combination with fentanyl and sufentanil during transurethral resection of the prostate (turp) under spinal anesthesia. materials and methods: in this prospective, randomized, double-blind trial, 60 patients undergoing elective turp under spinal anes...

Background: Various studies have investigated the role of different drugs as adjuncts to SBPB to prolong the duration and quality of analgesia without producing any major adverse effects. We conducted a study to compare the novel alpha 2 agonists (clonidine and dexmedetomidine) with respect to onset, duration of block and postoperative analgesia when added as adjuvants to the local anesthetic 0...

Guillain-Barré syndrome is divided into two major subtypes, acute inflammatory demyelinating polyneuropathy and acute motor axonal neuropathy. The characteristic electrophysiological features of acute motor axonal neuropathy are reduced amplitude or absence of distal compound muscle action potentials indicating axonal degeneration. In contrast, autopsy study results show early nodal changes in ...

BACKGROUND Use of an infraclavicular block is appropriate for surgery of the upper limb. However, it does not consistently block the entire brachial plexus. The aim of this study was to investigate whether increasing the dose of ropivacaine could enhance the success rate, onset time, and efficacy of the sensory and motor block during the use of a vertical infraclavicular block using neurostimul...
