The Efficacy of Regional Scalp Block Local Anesthesia as Preemptive Analgesia in Craniotomy Surgery
In Brief
A Early Phase 1 clinical trial evaluating nerve block with 0.5% ropivacaine and General anesthesia and opioids (fentanyl, propofol, rocuronium) for Scalp Nerve Block and Craniotomy Surgery. Completed, enrolled 40 participants across 1 site.
Detailed Summary
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.

Interventions
Compared to active comparator arm, the experimental arm received the same procedure except in the analgesia maintenance which was performed by nerve block of the scalp using 0.5% ropivacaine. However, during craniotomy surgery, pain may occur in patients in any arms. This was defined as a sudden rise of heart rate and blood pressure higher than 20% from baseline. In that case, a bolus of fentanyl was administered as rescue analgesia.
