简要总结

In summary, Dexmedetomidine and Ketamine can be effective adjuvants for Scalp Block Anaesthesia, with different profiles of efficacy and side effects. The choice of adjuvant should be based on the specific needs of the patient and the procedure, as well as the cliniciann’~~’~~s experience and comfort with each drug.Since there is no study comparing the effectiveness of Dexmedetomidine versus Ketamine as an adjuvant for Scalp Block in adults, we would like to compare the effectiveness of Dexmedetomidine (1 μg/kg)  with Ketamine (0.5 mg/kg) as an adjuvant to 20 ml 0.5% Ropivacaine  for Scalp Block infiltration in adult population aged 18-65 years undergoing Awake Craniotomy surgery. We hypothesize that addition of Ketamine 0.5 mg/kg is comparable to Dexmedetomidine 1 μg/kg as adjuncts to Ropivacaine 0.5% for prolonging the duration of analgesia post-Scalp Block in patients undergoing Awake Craniotomy surgery.
