Labat's classic approach to the sciatic nerve has not been able to show which motor response of the foot provides a more frequent rate of complete sensory and motor block. In this prospective, randomized, double-blind study, we compared plantar flexion with dorsiflexion with regard to onset time and efficacy of sciatic nerve block using the classic posterior approach. A total of 80 patients und...

BACKGROUND The aim of the study was to determine the median effective dose (ED50) for motor block of various concentrations of intrathecally administered plain bupivacaine. MATERIAL AND METHODS Between 2011 and 2013, 64 patients aged ≥70 years, undergoing transurethral, or lower limb surgery with combined spinal and epidural anesthesia in a single hospital were enrolled. The patients were ran...

Results: Excluding intercostobrachial nerve, the adequate sensory and motor block rates in group AX on the nerves of brachial plexus were found to be 100% and 92%-100%, respectively. Sensory and motor block rates were both found to be 96%-100% in group SC and also 80%-100%, and 88% in group IS, respectively. In terms of sensory and motor block evaluation of all the nerves, there were statistica...

INTRODUCTION Benefits of regional anesthesia can be prolonged by adding adjuvants to local anesthetics. This study was designed to test the efficacy of adding nalbuphine to bupivacaine in supraclavicular brachial plexus blockade using ultrasound (US) guidance. METHODOLOGY This was a prospective, randomized, double-blind study involving sixty patients of either sex undergoing elective orthoped...

OBJECTIVE In this study we aimed to compare the echogenic needles and the nerve stimulation addition to non-echogenic needles in ultrasound guided axillary brachial plexus block for upper extremity surgery. METHODS 90 patients were enrolled to the study. The patients were allocated into three groups randomly: Group E (n=30): ultrasound guided axillary block using echogenic needle, Group N (n=...

Background And Aims: Brachial plexus block is the cornerstone of regional anaesthesia practice. Various adjuncts have been used as adjuvants to ropivacaine in the past. This study was done to see the effect on duration of analgesia using dexmedetomidine as adjuvant to ropivacaine 0.5% in supraclavicular brachial plexus block (SBPB). Method: A total of eighty patients undergoing elective upper l...

The primary mode of action of local anesthetics is through sodium channel and axonal conduction blockade. Local anesthetics have also extensive effects on pre-synaptic calcium channels that must function to stimulate the release of neurotransmitters. Thus, interference with calcium channel conductance may enhance spinal anesthesia with local anesthetics. The present study was designed to invest...
