Background: There are different anesthetic techniques for AVF (Arterio-venous fistula) creation as general anesthesia, regional anesthesia and local anesthetic infiltration. Sympathetic nerve block is produced by regional anesthesia which increases intraoperative venous diameter and vessel flow, both intra-operatively and for several hours post-operatively. Regional anesthesia can maintain adeq...

 Abstract Background: Different adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and elongate the duration and quality of regional blocks. This study was performed to study the effects of one of the adjuvants, verapamil, in supraclavicular block. Methods: In this double blinded clinical trial, we divided 60 ASA class I and II patients who were to under...

BACKGROUND AND OBJECTIVES Success rate of catheter applications is low in supraclavicular block. Thus, bupivacaine and levobupivacaine become important with their long effect time in single injection practices. In this study, we aimed to compare the effectiveness, side effects and complications of bupivacaine and levobupivacaine in supraclavicular block. METHODS Sixty patients aged between 20...

Objectives: Alpha-2-receptor agonist has been used as an additive to local anaesthetics for various regional anaesthetic techniques. We compared clonidine and dexmedetomidine as an adjuvant to local anaesthetic agent in ultrasound guided axillary brachial plexus block with respect to hemodynamic parameters, onset and duration of sensory, motor block and duration of analgesia. Methods: Ultrasoun...

AIM To evaluate the effects of 0.5% levobupivacaine at 37 °C preheated from room temperature, on sensorial block, motor block, and haemodynamics in patients undergoing transurethral prostate resection (TUR-P). MATERIAL AND METHOD The patients were randomly allocated to two groups: Group I patients were injected with 3 mL 0.5% levobupivacaine solution which had been kept at room temperature fo...

OBJECTIVE To determine the dose of hyperbaric bupivacaine 0.5% required for unilateral spinal anesthesia during diagnostic knee arthroscopy. PATIENTS AND METHODS This prospective, randomized, clinical study was performed in 80 patients who were assigned to four groups to receive different doses of intrathecal hyperbaric bupivacaine (5 mg, 7.5 mg, 10 mg and 12.5 mg in Groups 1, 2, 3, and 4 res...

BACKGROUND The median effective dose (ED50) of a drug gives the amount or dose of drug needed to produce effective therapeutic response or desired effect in at least 50% of the population taking it. Our study focused on determining the ED50 required for effective motor block using hyperbaric and plain bupivacaine, and evaluated the influence of baricity on the ED50 required for motor block. MAT...

BACKGROUND A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. METHODS One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The infraclavicular brachial plexus ...
