A Clinical Comparative Study Between 0.5% Ropivacaine And 0.5% Ropivacaine And Dexamethasone 8mg In Supra Clavicular Brachial Plexus Block For Upper Limb Surgeries
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 10
Abstract
BACKGROUND AND AIMS: It has been reported that dexamethasone when used as an additive in a dose of 8mg to 0.5% ropivacaine in adults increases the duration of brachial plexus block. Hence this study was conducted to evaluate the efficacy of dexamethasone in supraclavicular brachial plexus block and to compare it without dexamethasone when added to ropivacaine 0.5% Materials and methods: Our study was conducted in 60 ASA grade I and II patients aged between20 – 60 years of either sex posted for hand, fore arm and elbow surgeries by using peripheral nerve stimulator guided supraclavicular brachial plexus block after obtaining written informed consent and permission from institutional ethical committee. These patients were divided into two groups. Group R (n = 30 ) received 25 ml of 0.5% ropivacaine plus 2ml of normal saline . Group D ( n = 30 ) received 25ml of 0.5% ropivacaine plus 2ml of dexamethasone ( 8mg ). Onset of sensory block, motor block, time to peak sensory and motor block, total duration of sensory block were recorded. Results: The two groups were comparable in demographic data. Group ‘D’ showed early onset of sensory and motor block (p<0.001)which was highly significant. Duration of sensory and motor block were significantly prolonged in Group ‘D’ (p< 0.001) which is highly significant. Conclusions: In our study we found that 8mgof dexamethasone as an adjuvant to 0.5% ropivacaine significantly prolongs the duration of brachial plexus block when compared to 0.5% ropivacaine alone.
