Abstract
INTRODUCTION
Brachial plexus block is an excellent method for attaining optimal operating conditions by producing complete muscular relaxation, maintaining stable intraoperative haemodynamics and the associated sympathetic block. In addition, they provide extended postoperative analgesia with minimal side effects. Different adjuvants have been described in literature to hasten the onset and prolong the duration of block. The present study was conducted to study the effect of adding dexamethasone to levobupivacaine in supraclavicular brachial plexus block.
AIM
To observe the effect of dexamethasone on onset and duration of anaesthesia, when used as an adjuvant to levobupivacaine in supraclavicular brachial plexus block.
MATERIALS AND METHODS
A total of 60 patients in the age group of 18-65 years belonging to ASA physical status I or II were included in the study. They are randomly allocated in two groups and each group included 30 patients. In group 1, patients received 30ml of 0.5% isobaric levobupivacaine with 2ml of isotonic sodium chloride. In group 2 patients received 8mg (2ml) dexamethasone in addition to 30ml of 0.5% isobaric levobupivacaine.
RESULTS
The results showed that the onset of sensory and motor block were faster in group 2(p<0.05). The duration of sensory and motor block were significantly longer in group 2 (p<0.05). VAS score at 12 hours were significantly lower in group 2 (p<0.05). None of the patients had bradycardia, hypotension or any other side effects.
CONCLUSION
Dexamethasone added to levobupivacaine for supraclavicular brachial plexus block reduces the time to onset of sensory and motor blockage and prolongs the duration of analgesia.
