BACKGROUND Unilateral spinal anesthesia is performed to provide restriction of sensory and motor block. OBJECTIVE The aim of this study was to compare unilateral and bilateral spinal anesthesia, with regard to limiting the nerve block exclusively to the area of surgery. METHODS This was a prospective, randomised, double-blind study, conducted in 40 consecutive outpatients scheduled for unil...

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...

BACKGROUND Although local anesthesia is a suitable method for upper limb surgeries, there is debate regarding the effects of appropriate dosing. OBJECTIVES In the current study, we investigated the effects of the concentration and volume of a local anesthetic on the beginning and quality of anesthesia during upper limb orthopedic surgeries. PATIENTS AND METHODS This double-blinded, randomiz...

BACKGROUND Tramadol, a 4-phenyl-piperidine analog of codeine, has a unique action in that it has a central opioidergic, noradrenergic, serotonergic analgesic, and peripheral local anesthetic (LA) effect. Many studies have reported contradictory findings regarding the peripheral analgesic effect of tramadol as an adjuvant to LA in brachial plexus block (BPB). This meta-analysis aimed to evaluate...

BACKGROUND Bicarbonate, as an adjunct increasing the non-ionized form of local anesthetics, can reduce latency and prolong duration of regional nerve block. Warming of local anesthetics decreases pKa and also increases the non-ionized form of local anesthetics. We warmed ropivacaine to body temperature (37℃) and evaluated the sensory block onset time, motor block onset time and analgesic durati...

PURPOSE The aim of this study is to apply combination of axillary plexus block with "selective" injection of nerves and continuous catheter technique, and to compare the anesthetic and postoperative analgesic effects of bupivacaine and levobupivacaine. METHODS In 30 scheduled patients for unilateral hand or forearm surgery, an axillary brachial plexus block with "selective" injection of nerve...

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...

Introduction: There are different methods to perform brachial plexus block. Interscalene and supraclavicular approaches are the most frequently used technique during upper limb surgeries.The aims of this study were to compare the onset and duration of sensory and motor block, hemodynamic parameters, sparing of analgesia in any dermatome and to observe any adverse effect during lower arm, elbow ...

Many techniques and drug regimens, with partial or greater success, have been tried from time to time to eliminate the anxiety component and to prolong the postoperative analgesia during regional anesthesia. α 2 agonists like clonidine, dexmedetomidine are used as adjuvant to local anaesthetics in order to prolong the duration of spinal anaesthesia. They potentiate the effect of local anestheti...
