Background andObjectives: This multicenter, randomized trial compared intravenous (IV) and perineural (PN) dexamethasone for ultrasound (US)-guided infraclavicular brachial plexus block. Our research hypothesis was both modalities would result in similar durations of motor block. Methods: One hundred fifty patients undergoing upper limb surgery with US-guided infraclavicular block were randomly...

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...

AIM Comparing the effectivity of prilocaine and prilocaine alkalinized with 8.4% NaHCO3 in terms of sensory and motor block onset and termination durations in RIVA technique considering patients' satisfaction and tolerance with application of tourniquet undergoing hand-wrist surgery. MATERIALS AND METHODS 64 patients were randomised into two groups. First group (Group P) was administered pril...

BACKGROUND AND OBJECTIVES To observe the motor and sensorial block characteristics with different dosage of levobupivacaine during spinal block for the patients undergoing day-case knee arthroscopy. MATERIAL AND METHOD Eighty, 80 ASA physical status I-II patients, undergoing day-case knee arthroscopy received 0.5% levobupivacaine; 7.5 mg in Group I, 10 mg in Group II, 12.5 mg in Group III and...

OBJECTIVE To determine the median effective dose (ED50) for motor block of intrathecally administered different concentrations of bupivacaine in younger patients. METHODS This study was conducted at the Department of Anesthesiology, The First College of Clinical Medical Science, China Three Gorges University, China, on 40 American Society of Anaesthesiologists (ASA) I-II younger patients (18-...

BACKGROUND Sciatic nerve block when combined with femoral nerve block for total knee arthroplasty may provide superior analgesia but can produce footdrop, which may mask surgically induced peroneal nerve injury. In this prospective, randomized, observer-blinded study, we evaluated whether performing a selective tibial nerve block in the popliteal fossa would avoid complete peroneal motor block....

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...

The clinical presentation of a subarachnoid block (SAB) is dependent upon the intrathecal spread of local anesthetic (LA). Intrathecal distribution depends on the chemical and physical characteristics of LA, puncture site, technique used, patient anatomical characteristics and hydrodynamic properties of cerebrospinal fluid. We tried to determine whether a combined glucose/LA solution can render...
