Overview
This study aims to compare dexmedetomidine as an adjuvant to bupivacaine in scalp block versus bupivacaine alone for postoperative pain management in patients undergoing craniotomy.
Detailed description
Scalp block is proposed as a multimodal approach to preventing postoperative pain and hemodynamic responses to previous noxious stimulation during the operation.
The use of adjuvants, such as dexmedetomidine, a highly selective alpha-2 adrenergic receptor agonist, has recently been studied for its analgesic effects. Dexmedetomidine acts additionally to local anesthetics, prolonging their duration of action.
Interventions
- Other Scalp block
Patients will receive a scalp block with bupivacaine alone. - Other Scalp block + Dexmedetomidine
Patients will receive a scalp block with dexmedetomidine as an adjuvant to bupivacaine.
Primary outcome measures
- Cumulative postoperative morphine consumption [Time frame: 24 hours postoperatively]
Secondary outcome measures (5)

- Degree of pain [Time frame: 24 hours postoperatively]
- Time for 1st rescue analgesia [Time frame: 24 hours postoperatively]
- Incidence of complications [Time frame: 24 hours postoperatively]
