normal 0 false false false en-us x-none ar-sa background: regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities . in this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. materials and methods: in this double-blind ra...

conclusions the length of sensory and motor blockade is shorter in chronic opioid abusers. adding 10 µg sufentanil to hyperbaric bupivacaine in opium abusers lengthened the sensory and motor block duration. results the duration of sensory and motor block were significantly less in group c (537.0 ± 40.1 minutes, 479.0 ± 34.8 minutes) and the longest duration of sensory and motor block was observ...

conclusions intrathecal midazolam 2 mg provides significantly longer and effective postoperative analgesia with no side effects. results postoperative analgesia was significantly longer in the midazolam group compared to the control group (201.5 minutes vs. 357.6 minutes). the mean onset times of the sensory and motor blocks were significantly faster (p < 0.01) in the midazolam group compared t...

conclusions the volume of the injected anesthetic accelerated the onset of sensory and motor block without affecting the rate of success in our patients. results the onset of sensory and motor block was significantly shorter in the 1.3% lidocaine group than in the 2% lidocaine group (p ≤ 0.05). the success rate of sensory and motor block was not different. the quality (completeness) of sensory ...

conclusions the findings showed that adding sufentanil or midazolam to bupivacaine shortens the onset of spinal anesthesia and increases the time duration of anesthesia; however it does not change the motor block recovery time. adding sufentanil delays the first request for narcotic analgesics while adding midazolam leads to a decrease in nausea and hypotension. adding sufentanil or midazolam d...

conclusions dexmedetomidine added to bupivacaine in spinal anesthesia is more effective to increase duration of block, providing more appropriate sedation and less postoperative pain scale and post-operative nausea and vomiting (ponv) compared to fentanyl additive. results totally, 84 patients were randomly divided into three groups of 28 patients. onset of sensory block in dex group was signif...

background and aims: infraclavicular nerve block (icnb) is one of the most efficacious peripheral nerve blocks for upper extremity procedures, associated with several potential complications. recently, some authors have recommended ultrasound-guided peripheral nerve block for icnb. the current study is aimed to compare the outcomes of icnb utilizing combined ultrasound guidance and neurostimula...

Background: Alpha-2 agonists are added to local anesthetic agents to extend the duration of peripheral nerve blocks. Objective: We evaluated the effect of combining dexmedetomidine with levobupivacine with respect to duration of motor and sensory block and duration of analgesia. Material and Methods: Sixty patients of ASA grade I or II aged between 18-60 years, posted for elective upper limb su...
