Intranasal Dexmedetomidine Versus Oral Midazolam Premedication for Postoperative Negative Behavior Changes in Children
Intranasal Dexmedetomidine Versus Oral Midazolam Premedication for Postoperative Negative Behavior Changes in Children: A Randomized Controlled Trial
The goal of this clinical trial is to learn the effect of dexmedetomidine premedication in postoperative negative behavior changes in children compared to midazolam premedication. It will also learn about the effect of dexmedetomidine and midazolam in emergence delirium. The main questions are:
- Dose dexmedetomidine lower the incidence of postoperative negative behavior changes compared to midazolam?
- Dose dexmedetomidine lower the incidence of emergence delirium compared to midazolam? Researchers will compare dexmedetomidine to midazolam (a common pediatric premedication) to see if dexmedetomidine works to treat postoperative negative behavior change and emergence delirium.
Participants will:
- Take intranasal dexmedetomidine or oral midazolam or placebo (a look-alike substance that contains no drug) premedication
- Fill in the Post hospitalization behavior questionnaire for ambulatory surgery postoperative 1, 3, 7, and 30

Detailed Description
Due to the fear of being separated from parents, fear of venipuncture, and facing unfamiliar operating room environment, children have different degrees of anxiety before surgery. Preoperative anxiety can lead to strong stress response and increase the incidence of emergence delirium. It can even cause psychological trauma and affect children's physical and mental health growth. The study showed that preoperative anxiety was positively correlated with the incidence of emergence delirium and postoperative negative behavior change, and emergence delirium was a risk factor for postoperative negative behavior in children.
Currently, midazolam is the most commonly used sedative drug to relieve preoperative anxiety in children. Midazolam has anterograde amnesia effect, reducing the occurrence of intraoperative awareness, and alleviating psychological trauma and memory of malignant stimulation in children. Dexmedetomidine is a highly selective α2 adrenergic agonist with anxiolytic, sedative, and analgesic properties. Our previous study found that preoperative administration of dexmedetomidine can reduce the incidence of emergence delirium in children compared with midazolam However, no clinical studies have directly compared the effects of dexmedetomidine and midazolam premedication on postoperative negative behavior change in children.
This prospective randomized controlled trial was conducted to compare the effects of dexmedetomidine and midazolam premedication on preoperative anxiety, the incidence of postoperative delirium, and postoperative negative behavior changes in children to provide a reference for optimizing clinical anesthesia medication regimens.

|
Incidence of emergence delirium
Time Frame: Within 30 min after extubation
|
Emergence delirium will be assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale (defined as a PAED score of ≥10).
|
Within 30 min after extubation
|
Length of postanesthesia care unit stay
Time Frame: Up to 60 minutes postoperatively
|
Length of postanesthesia care unit stay is defined as the time between arrival in the PACU and readiness for discharge from the PACU (defined as a modified Aldrete score of ≥9).
|
Up to 60 minutes postoperatively
|
Emergence time
Time Frame: About up to 30 minutes postoperatively
|
Emergence time is defined as the interval from discontinuation of inhalation anesthetic to eye-opening on verbal command.
|
About up to 30 minutes postoperatively
|
Parental satisfaction
Time Frame: Postoperative day 1
|
Parental satisfaction is self-reported using a five-point Likert scale (5=very satisfied, 4=satisfied, 3=neither satisfied nor dissatisfied, 2=dissatisfied, and 1=very dissatisfied).
|
Postoperative day 1
|
Postoperative pain intensity
Time Frame: After extubation 10, 20, 30 min, and postoperative 1 day
|
Postoperative pain intensity will be measured using the face, legs, activity, cry, and consolability sacle.
|

|
Preoperative anxiety
Time Frame: Before the intervention in holding area
|
Preoperative anxiety will be assessed using the modified Yale preoperative anxiety scale.
Scores range from 23 to 100 with higher scores indicating greater anxiety.
|
Before the intervention in holding area
|
Parental separation anxiety
Time Frame: After intervention 30 minutes
|
Preoperative sedation level will be measured using the parental separation anxiety scale (PSAS).
The PSAS is a 4-point scale as follows: 1=easy separation; 2=whimpers; 3=cries and cannot be easily reassured, but not clinging to parents; and 4=crying and clinging to parents.
A PSAS score of 1 or 2 was considered as "acceptable" separation.
