Overview
Patients with Supratentorial tumor undergoing craniotomy have a higher risk of postoperative pain, which will affect their postoperative quality of recovery (QoR). Although scalp nerve block (SNB) can alleviate postoperative pain, the effect on postoperative QoR in patients with supratentorial tumor undergoing craniotomy is still unclear. This study is aimed to explore the effect of SNB on postoperative QoR in this population. To explore the effect, we design a randomized controlled trial in which 84 patients with supratentorial tumor will be randomly assigned to either the SNB group or control group. The primary outcome is 15-item QoR score at 24 h after surgery. The secondary outcomes include 15-item QoR scores at 72 h after surgery, Riker Sedation-Agitation Scale, nausea and vomiting, intraoperative opioids and propofol consumption, perioperative heart rate and mean artery pressure, the duration of anesthesia and surgery, time to extubation, PACU duration, the length of postoperative days, adverse events within 72h and total medical expenses.
