The Efficacy of Regional Scalp Block in Craniotomy

The Efficacy of Regional Scalp Block Local Anesthesia as Preemptive Analgesia in Craniotomy Surgery

The objective of this clinical trial is to evaluate the role of scalp nerve block in craniotomy. The primary questions it seeks to answer are: What are the efficacy and safety profiles of scalp nerve block in craniotomy? The anesthesia protocol and monitoring were standardized for all participants. Participants were divided into two groups: the scalp nerve block group and the general anesthesia group. General anesthesia was induced using fentanyl (1-2 mcg/kg), propofol (1-2 mg/kg), and rocuronium (0.6 mg/kg). In the scalp nerve block group, a nerve block was administered using 0.5% ropivacaine.
