Özet: Introduction: Arthroscopic shoulder surgeries can be done under general anaesthesia, regional anaesthesia or a combination of both. In patients undergoing shoulder arthroscopy, pain can persist for more than 48 hours in the postoperative period despite multimodal analgesia, thus making pain control challenging for anesthesiologists. Materials and Methods: Institutional ethics committee approval was sought before commencing this prospective observational study. Patients of American Society of Anaesthesiologists physical status (ASA PS) I or II, aged 19-76 years of either gender scheduled for elective arthroscopic shoulder surgeries (Surgery done in lateral position) under interscalene block using 50 mcg of Dexmedetomidine as adjuvants along with 15 mL of 2% lignocaine and 15 mL of 0.5% bupivacaine were included in the study. Patients who refused to participate, those with neurological deficits, known allergy to local anaesthetics and history of seizures were excluded. Informed consent was obtained from all participants. Consultant anaesthesiologists administered the USG guided interscalene blocks with 15 mL of 2% lignocaine and 15 mL of 0.5% bupivacaine and Dexmedetomidine as adjuvant. Ultrasound guided interscalene block using linear probe and 26G needle without using nerve stimulator.Results: Fifty five male and eight female patients participated in the study. Fifty patients belonged to ASA PS I and 13 patients belonged to ASA PS II. Age, weight and the duration of surgery were comparable between all the patients. Dexmedetomidine as an adjuvant to lignocaine and bupivacaine prolongs ultrasound guided interscalene blockade is more efficaciently in hastening the onset, prolonging sensorimotor blockade and delaying the time for request of rescue analgesia.Conclusion: Dexmedetomidine as an adjuvant to lignocaine and bupivacaine prolongs ultrasound guided interscalene blockade is more efficaciently in hastening the onset, prolonging sensorimotor blockade and delaying the time for request of rescue analgesia. Dexmedetomidine also provides Intraoperative sedation, which is very helpful for conducting the surgery. Keywords: Arthroscopic, Dexmedetomidine, lignocaine, interscalene blockade
