Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intercostobrachial nerve block will be performed with 5 ml solution (study drug which is either 1% lignocaine or saline as placebo). At 5 minutes after the intercostobrachial nerve block with the study drug, the sensation on the medial site of the forearm will be checked with ice. Then,axillary brachial plexus block will be performed with 20 ml of local anaesthetics (10 ml of 2% lignocaine and 10 ml of 0.75% ropivacaine).
A tourniquet will be inflated just before starting the surgery.
The pain score will be assessed every 5 minutes after the tourniquet is inflated.
