BACKGROUND We conducted prospective, randomized, observer-blinded trial to compare two double-injection perivascular (PV) ultrasound-guided techniques of axillary brachial plexus block (BPB). METHODS American Society of Anesthesiologists physical status I-II, 50 patients undergoing surgery of the forearm, wrist or hand were randomly allocated to two groups. For PV12 group, injection was carri...

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...

BACKGROUND Magnesium is a physiologic cation that blocks neuromuscular transmission and does not allow the nerve to be stimulated. OBJECTIVES This study investigates the effect of adding magnesium sulfate to lidocaine to extend the duration of sensory and motor blocks of the axillary plexus in orthopedic surgeries of the upper extremities. PATIENTS AND METHODS This controlled randomized dou...

In this issue, we look at the axillary brachial plexus block and the terminal nerves of the hand. The axillary block is an approach that has maintained its simplicity and effectiveness throughout the years. Most anaesthesiologists will reminiscence this technique being amongst their first experiences in regional anesthesia. With the advent of ultrasound, this block is now more reliable than eve...

Little is known about the learning of the skills needed to perform ultrasound- or nerve stimulator-guided peripheral nerve blocks. The aim of this study was to compare the learning curves of residents trained in ultrasound guidance versus residents trained in nerve stimulation for axillary brachial plexus block. Ten residents with no previous experience with using ultrasound received ultrasound...

BACKGROUND The aim of this study was to compare the efficacy of axillary brachial plexus block using an ultrasound-guided method with the nerve stimulator-guided method. We also compared the efficacy of ultrasound-guided single-injection with those of double-injection for the quality of the block. METHODS Ninety patients scheduled for surgery of the forearm or hand were randomly allocated int...

PURPOSE The purpose of this study is to determine if real time ultrasound guidance improves the success rate of axillary brachial plexus blockade. METHODS Patients undergoing elective hand surgery were randomly assigned to one of three groups. Axillary blocks were performed using three motor response endpoints in the nerve stimulator (NS) Group, real-time ultrasound guidance in the ultrasound...
