Abstract

Rapid onset of sensory block and prolonged postoperative analgesia with haemodynamic stability without neuro and cardiotoxicity are important goals in regional anaesthesia. Axillary block is the most distal block performed on the brachial plexus (except for single nerve blocks in the arm and forearm). Because of its distal location, the axillary block have negligible risks of the respiratory compromise secondary to pneumothorax or phrenic nerve blockade. In addition, the peripheral location permits adequate arterial tamponade to be apllied if an advertent puncture occurs. This study was conducted on 80 patients of ASA I & II and were randomly allocated in two groups receiving two different concentrations of ropivacaine through axillary approach. Onset and duration of sensory and motor block was observed, patients with partial or incomplete block were managed accordingly by supplementing sedatives and analgesics. The rate of complete sensory and motor block was higher in both groups at 10, 15 and 20 mins. Onset of sensory bock in group I and II was 18.48±1.52 mins and 18.88±1.45 mins. Onset of motor block in both groups was 19.48±3.84 mins and 20.56±3.78 mins. No significant stastistical differences were observed with different concentrations of ropivacaine, hence it can be concluded that higher concentration does not have additional benefits, both concentrations were found equally good and potent.
