Introduction: Lignocaine with adrenaline is used with local anaesthetics to improve the onset and increase the duration of nerve block. The present study aimed to evaluate it's effect when used together with ropivacaine. Objective: To evaluate the effect of adding 2% lignocaine with adrenaline to 0.5% ropivacaine, for supraclavicular brachial plexus blockade on the onset and duration of sensory...

BACKGROUND Apha-2 agonists are combined with local anesthetics to extend the duration of regional anesthesia. We evaluated the effect of combining dexmedetomidine with levobupivacine with respect to duration of motor and sensory block and duration of analgesia. METHODS Sixty patients scheduled for elective forearm and hand surgery were divided into two equal groups in a randomized double blin...

PURPOSE To comparatively study the efficacy and maternal and fetal side-effects of two doses of bupivacaine associated with morphine and clonidine, administered by the subarachnoid route for cesarean section. METHODS The study included 66 pregnant women at term, distributed into two groups. GI: bupivacaine 8.0 mg (1.6 mL) + clonidine 75 µg (0.5 mL) + morphine 100 µg (1.0 mL) and GII: bupivaca...

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 Although lidocaine is a cheap and globally available local anesthetic, yet it is not a popular drug for labor analgesia. This is claimed to its higher intensity of motor block, possibility of transient neurological symptoms (TNS) and its placental transfer with probable drawbacks on fetal well-being. However, these effects could be concentration dependent and, the evidence linking th...

Background The aim is to compare the clinical effect of three different concentrations of levobupivacaine (0.25%, 0.125%, and 0.0625%) on the sensory and motor block characteristics and mode of delivery during epidural labor analgesia. We also studied the pharmacokinetic profile of the three concentrations during labor. Materials and Methods Sixty pregnant females undergoing normal vaginal de...

This paper presents the design optimization of axial flux surface mounted Permanent Magnet Brushless DC motor based on genetic algorithm for an electrical vehicle application. The rating of the motor calculated form vehicle dynamics is 250 W, 150 rpm. The axial flux surface mounted Permanent Magnet Brushless DC (PMBLDC) motor was designed to fit in the rim of the wheel. There are several design...

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 randomized clinical trial, 90 patients, candidate...

OBJECTIVES To determine the effect of adding dexmedetomidine to bupivacaine for neuraxial anesthesia. METHODS Sixty-six patients were studied between April and May 2008 in the University of Jordan, Amman Jordan. They were randomly assigned into 3 groups, each receiving spinal bupivacaine 12.5mg combined with normal saline (group N) Dexmedetomidine 5 microg (group D5), or dexmedetomidine 10 mi...

Background: Many researchers have been done to find an ideal adjuvant to ropivacaine in regional anaesthesia that inhibits intra and post-operative pain and prolong the duration of anaesthesia without any side effects. Aim: This study was conducted to evaluate the onset, extent and duration of sensory and motor block and side effects of clonidine or dexmedetomidine when used as an adjuvant to r...
