A Comparative Analysis of Combined Superficial Cervical Plexus and Supraorbital Blocks Compared to Scalp Blocks During Craniotomy: a Review of Opioid Consumption and The Suppression of Hemodynamic Responses

The combined anaesthesia technique involves the use of general anaesthesia and regional block in the superficial cervical plexus and supraorbital areas, with 6 ml of 0.25% bupivacaine injected into the superficial cervical plexus area and 2 ml into the supraorbital area.

A combination anaesthesia technique is used that involves general anaesthesia and scalp block. Scalp block using 0.25% bupivacaine in the supraorbital area (2 ml), supratrochlear (2 ml), zygomaticotemporal (2 ml), auriculotemporal (2 ml), major occipital (2 ml) and minor occipital (2 ml).
