Remimazolam with sevoflurane to reduce wake-up agitation in children after neurosurgery.

The Effect of Remimazolam on Emergence Delirium in Pediatrics Undergoing Neurosurgery With Sevoflurane Anesthesia

Phase 4 Interventional Peking University First Hospital · NCT07046364

This trial will test whether adding a single bolus of remimazolam to sevoflurane anesthesia lowers the chance that children ages 1–6 become agitated as they wake up from neurosurgery.

What this trial studies

Children aged 1–6 scheduled for elective neurosurgery lasting more than one hour under sevoflurane anesthesia will be enrolled and receive either a single bolus of remimazolam or a saline placebo in addition to routine anesthetic care. Participants will be followed through recovery to compare the incidence of emergence delirium between the remimazolam and control groups. Standard safety monitoring will be performed during and after anesthesia, and patients with recent sedative use or benzodiazepine allergy will be excluded. The trial builds on prior observations that a remimazolam bolus may reduce postoperative agitation and applies that approach specifically in a pediatric neurosurgery population.

Who should consider this trial

Good fit: Children aged 1–6 years who are scheduled for elective neurosurgery under general anesthesia with an expected duration over one hour and who do not have benzodiazepine allergy are ideal candidates.

Not a fit: Children with benzodiazepine allergy, recent use of other sedatives, ASA class IV or higher, or impairments that prevent emergence delirium assessment are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, adding remimazolam could reduce how often and how severely children experience agitation when waking up after neurosurgery, making recovery smoother.

How similar studies have performed: A prior study reported that a single remimazolam bolus was associated with a lower incidence of postoperative agitation, providing supportive but not definitive evidence for this approach.
