Overview

The goal of this clinical trial is to learn the effects of remimazolam for total intravenous anesthesia on the neurodevelopment of children aged 3-6 years who underwent tonsil/adenoid removal surgery after general anesthesia when compared with propofol. It will also learn about the safety of remimazolam used for children. The main questions it aims to answer are: * Does remimazolam improve the postoperative neurodevelopmental outcomes of the children after general anesthesia compared with propofol? * What medical problems do participants have when receive remimazolam for general anesthesia? Researchers will compare remimazolam to propofol to see if remimazolam improve the postoperative neurodevelopmental outcomes of the children after general anesthesia. Participants will: * Receive remimazolam or propofol for general anesthesia induction and maintenance * At 1-3 years after the surgery, the Wechsler Preschool and Primary Scale of Intelligence - Fourth Edition was used for face-to-face assessment of the children's neurodevelopmental status. * Use scales such as BRIEF-P and CBCL to conduct face-to-face assessments of the patient's cognitive functions in other areas.

Interventions

  • Drug Remimazolam based total intravenous anesthesia
    For patients who aged between 3 and 6 years old undergoing tonsillectomy or/and adenoidectomy, anesthesia induction will performed with remimazolam in a dose of 0.4 - 0.5 mg/kg anesthesia maintenance was administered with remimazolam at a rate of 1.0 - 3.0 mg/kg/h.
  • Drug Propofol based general anesthesia
    For patients who aged between 3 and 6 years old undergoing tonsillectomy or/and adenoidectomy, anesthesia induction will performed with propofol in a dose of 2.0 - 3.5 mg/kg , anesthesia maintenance was administered with propofol at a rate of 4 - 12 mg/kg/h.

Primary outcome measures

  • full-scale intelligence quotient [Time frame: one year after surgery]
Secondary outcome measures (5)
  • Memory and learning ability [Time frame: The first to the third year after the operation]
  • Language and Reading Skills [Time frame: The first to the third year after the operation]
  • Executive Function and Attention [Time frame: The first to third year after operation]
  • Behavior and Emotion Assessment [Time frame: The first to third year after surgery]
  • Motor development [Time frame: The first to third years after surgery]

Eligibility criteria

Exclusion criteria

  • Those who were exposed to general anesthetic drugs during infancy or in the late pregnancy of the mother;
  • Known chromosomal abnormalities or other known acquired or congenital diseases that may affect neural development, such as cerebral palsy, autism spectrum disorder or attention deficit hyperactivity disorder (ADHD), etc.;
  • Patients with severe liver dysfunction (Child-Pugh C grade);
  • Patients with severe kidney dysfunction (requiring dialysis before surgery);
  • Patients with a history of congenital heart disease requiring surgery or drug treatment;
  • Those allergic to the study drugs remimazolam or propofol;
  • Any known neural damage, such as cystic periventricular leukomalacia or grade 3 or 4 intraventricular hemorrhage;
  • Social or geographical factors that may lead to postoperative loss of follow-up;
  • Planned to undergo two surgeries within 7 days after the surgery;
  • Those currently participating in other clinical trials;
  • Those receiving special care or living in social welfare institutions or any other factors that may affect their ability to participate in the study.
