OBJECTIVE To compare axillary brachial plexus block and Bier's block as methods of providing upper limb anaesthesia. METHODS Axillary brachial plexus or Bier's blocks were performed on all patients requiring upper limb anaesthesia in a three month period. For Bier's block, a single cuff tourniquet and 3 mg/kg 0.5% prilocaine were used. For axillary plexus block, 40 ml 1% lignocaine with adren...

To evaluate the effect of adding midazolam to bupivacaine to prolong the analgesia characteristics of brachial plexus block. After preanaesthetic assessment all the patients were premedicated with diazepam 0.1mg/kg orally one hour before the surgery. Patients were randomly divided into group1 & 2. Group -1 patients received supraclavicular brachial plexus block with 30ml of 0.5% bupivacaine & g...

Dr Nair’s letter to the editor regarding the failed nerve blocks mentioned in our paper, “Comparison of the supraclavicular, infraclavicular and axillary approaches for ultrasound-guided brachial plexus block for surgical anesthesia”,1 raised several points that I believe are worth looking at in more detail. We are grateful for Dr Nair’s comments which have contributed to the furthering of scho...

BACKGROUND This prospective, randomized, blinded study tested the hypothesis that ultrasound guidance can shorten the onset time of axillary brachial plexus block as compared with nerve stimulation guidance when using a multiple injection technique. METHODS Sixty American Society of Anesthesiology physical status I-III patients receiving axillary brachial plexus block with 20 ml ropivacaine, ...

BACKGROUND Previous studies have been conducted to evaluate the effect of different adjuvants on brachial plexus block. OBJECTIVES This study investigated the effect of adding magnesium sulfate to lidocaine on postoperative pain in upper limb surgeries by supraclavicular brachial plexus block under ultrasound guidance. METHODS This study was carried out on patients who were candidate for up...

Three methods of blocking the brachial plexus with a supraclavicular approach are presented. The pros and cons of using this technique, as well as its usefulness, are discussed. The four most commonly used drugs for blocks also are examined. A 270% increase in blood flow to the arm is achieved by this block but, with the addition of epinephrine, it can be increased to 430%. The permeability of ...

Background: Several clinical studies have shown that clonidine prolongs sensory motor blockade when used with bupivacaine but ideal doses of clonidine on ropivacaine is not well defined and to evaluate the effect of two doses of clonidine on ropivacaine, for supraclavicular brachial plexus blockade. Methods: In a prospective randomized double blind study supraclavicular brachial plexus blockade...

Comparison of the trans-arterial and Winnie techniques of axillary brachial plexus block was made in two groups of patients. This study did not find any statistical difference between the two techniques.

The use of ultrasound in clinical anaesthesia has largely contributed to the development nerve block technique recent years. In standard ultrasound-guided interscalene brachial plexus block, C5 and C6 roots are directly infiltrated. Hemi diaphragmatic paresis almost usually follows arthroscopic shoulder surgery, despite fact that it offers highly effective postoperative analgesia [1].
