Secondary
| Measure | Time frame |
|---|---|
| Heart rate and mean arterial pressure response at 30 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes and 5 minutes after skull pin fixation at 30 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes and 5 minutes after skull pin fixation Mean arterial pressure (MAP) measured using an arterial line (a-line),Duration of scalp block the time required to perform the scalp block time count,Postoperative pain 12 and 24 hours postoperatively the verbal numerical rating scale (vNRS) or the behavioral pain scale (if vNRS cannot be obtained),Cumulative intraoperative propofol consumption intraoperative period data recorded by the infusion pump,Cumulative intraoperative fentanyl consumption intraoperative period data recorded by the infusion pump,Cumulative fentanyl consumption in the first 24 hours postoperatively duration of the first 24 hours postoperatively recorded by the nurse,Scalp block-related postoperative adverse events at 24 hours postoperatively, including: Hypotension (SBP less than 90 mmHg) Bradycardia (HR less than 50 bpm) Facial nerve palsy 24 hours postoperatively observed by the nurse | — |
