Clinical Trial Summary

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.

Intervention

Procedure:
• scalp nerve block
In the SNB group, bilateral scalp nerve blocks will performed using 20 mL of 0.75% ropivacaine after anesthesia induction. To cover the area of surgical incision and skull clamp, seven scalp nerves including the supratrochlear, supraorbital, zygomaticotemporal, auriculotemporal, lesser occipital and greater occipital nerves, are blocked bilaterally by injecting 1-2 ml of the solution using a 25-gauge needle.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the 15-item QoR score at 24 hours after surgery	The quality of postoperative recovery is assessed by QoR-15 on the first day after operation.	up to day1 after surgery
Secondary	the 15-item QoR score at 72 hours after surgery	The quality of postoperative recovery is assessed by QoR-15 on the third day after operation.	up to day3 after surgery
Secondary	postoperative pain scores	Pain intensity is evaluated with the numerical rating scale (0-10, 0 = no pain, 10 = unbearable pain) at 6 time points: 20 minutes after extubation, discharge from PACU, 6 hours, 12 hours, 24 hours, and 72 hours following surgery. The worst pain score during each interval is recorded.	up to day3 after surgery
Secondary	Riker Sedation-Agitation Scale	Riker Sedation-Agitation Scale is assessed at 2 time points: 20 minutes after extubation and discharge from PACU.	during in PACU, an average of 3 hours
Secondary	nausea and vomiting	Nausea and vomiting is assessed by postoperative nausea and vomiting score (0, no nausea or vomiting; 1, nausea but no vomiting; 2, vomiting once or twice; 3, vomiting on more than two occasions) at 3 time points: discharge from PACU, 24 hours, and 72 hours after operation.	up to day3 after surgery
Secondary	opioids and propofol consumption	Total drug dose of sufentanil, remifentanil and propofol consumption is recorded during operation and in PACU.	during operation and in PACU, an average of 8 hours
Secondary	mean artery pressure and heart rate	Mean artery pressure and heart rate are recorded at 6 time points: before anesthesia induction (T0), after placement of the skull clamp (T1), beginning of surgery (T2), end of surgery (T3), 20 minutes after extubation (T4) , and discharge from PACU (T5).	during operation and in PACU, an average of 8 hours
Secondary	time to critical events	The time to critical events are recorded, including the duration of anesthesia and surgery, time to extubation, PACU duration, postoperative hospital days and so on.	during hospitalization, an average of 10 days
Secondary	adverse events	Adverse events within 72 hours after operation are recorded.	up to day3 after surgery
Secondary	total medical expenses	The total medical expenses is recorded during hospitalization.	during hospitalization, an average of 10 days
