Interventions
Induction of general anesthesia will be done by IV propofol 2-2.5 mg / kg and IV fentanyl lug/kg. After IV Cis-atracurium 0.15mg/kg, endotracheal intubation will be done.
The scalp block will target six pairs of sensory nerves that innervate the scalp: the supraorbital nerve, supratrochlear nerve, auriculotemporal nerve, zygomaticotemporal nerve, greater occipital nerve, and lesser occipital nerve. Local anesthetic (2% lidocaine and bupivacaine) will be infiltrated at specific anatomical landmarks corresponding to the course of each nerve.
