Abstract
Supraclavicular brachial plexus block is most important and effective type of upper limb regional anesthesia as it provides excellent anesthesia and post- operative analgesia in comparing with general anesthesia ,and using of nerve stimulator help anesthetist to increase of block success rate and avoids the complications it may be happen . Increasing the duration of local anaesthetic action is often desirable because it prolongs surgical anaesthesia and analgesia. Steroids have powerful anti-inflammatory as well as analgesic property. Perineural injection of steroids is reported to influence post-operative analgesia. This study evaluated the effect of adding dexamethasone as an adjuvant to levobupivacaine on postoperative opioid requirements and its effect on postoperative pain scores after supraclavicular block. We made a comparison between two groups of patients, each group consists of twenty five patients scheduled for forearm and hand orthopedic surgeries and anaesthetized by nerve stimulator-guided supraclavicular nerve block, group L was anaesthetized by injection of levobupivacaine and group LD received levobupivacaine dexamethasone mixture All groups were assessed for efficacy of the block by assessing sensory and motor block onset and duration and , postoperative analgesia were assessed by visual analogue scale Conclusion: there were rapid onset and prolongation of sensory and motor block with prolonged duration of post- operative analgesia and less post-operative analgesic requirement, in group of patients that were received dexamethasone and levobupivacaine than the group of patients were received levobupivacaine only.
