Brief 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.

DRUGGeneral anesthesia and opioids (fentanyl, propofol, rocuronium)

Compared to experimental arm, the active comparator arm received the same procedure except in the analgesia maintenance which was performed through continuous fentanyl infusion. 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.

Design outcomes

Primary

MeasureTime frameDescription
Total opioid consumptionFrom enrollment until 24 hours post craniotomy surgery.Opioid used was fentanyl, and it was administered during and post surgery which was measured μg/kg.

Secondary

MeasureTime frameDescription
Pain Scale0 to 24 hours after surgeryPain scale was assessed using the Critical-care Pain Observational Tool (CPOT) every 4 hours
Laboratory MarkersAfter induction of anesthesia, 6 hours after incision, and 24 hours after surgery.Laboratory markers measured were Interleukin (IL)-6 (pg/mL), Tumor Necrosis Factor (TNF)-α (pg/mL), prostaglandin E2 (PGE2) (pg/mL), cortisol level (μg/dL), blood glucose level (mg/dL), neutrophil count (cells/μL), lymphocyte count (cells/μL) and neutrophil-to-lymphocyte ratio (NLR).
The patients with PONV0 to 24 hour after surgeryPostoperative nausea and vomiting
