Highlights
Adding adjuvants to local anaesthetics in brachial plexus block is known to enhance the quality and duration of analgesia
Dexmedetomidine as an adjuvant to 0.2% ropivacaine in ultrasound guided interscalene blockade is more efficacious than dexamethasone in hastening the onset, prolonging sensory blockade and delaying the time of request for rescue analgesia
Dexmedetomidine produces mild sedation compared to dexamethasone as an adjuvant
Summary
Adding adjuvants to local anaesthetics in brachial plexus block is known to enhance the quality and duration of analgesia. This study was undertaken to compare 1 μg/kg of dexmedetomidine, or 100 μg/kg of dexamethasone added as adjuvants to 0.2% ropivacaine in ultrasound guided interscalene brachial plexus block for arthroscopic shoulder surgeries. Interscalene brachial plexus block is one of the most widely practiced regional anaesthetic technique for shoulder surgeries and it provides better analgesia, greater satisfaction and fewer side effects. Adjuvants to local anaesthetics improve the quality of analgesia, prolong duration of blockade and reduce the dose of local anaesthetics.[1,2,3,4] In this study we observed and compared the efficacy of two adjuvants – dexmedetomidine and dexamethasone with 0.2% ropivacaine. Aim of the study was to compare the block characteristics with dexmedetomidine and dexamethasone as adjuvants to 0.2% ropivacaine in ultrasound guided (USG) interscalene block for arthroscopic shoulder surgeries. Secondary objectives were to compare the onset, duration of motor blockade, time of request for rescue analgesia and sedation score
