Anxiety
Conditions
Brief summary
Children tend to anxiety and even fear before survey. And this kind of anxiety will not result in the forced induction of anesthesia, but also may increase the incidence of postoperative agitation in children, even lead to postoperative behavior changes.Currently,Oral midazolam or intranasal dexmedetomidine alone is commonly used as a preoperative regimen, but the clinical effects of each single-use are not satisfactory. In the investigators' study，the researchers conducted the current study to investigate whether dexmedetomidine combined with midazolam can increase the rate of satisfactory anesthesia induction in pediatric patients and achieve better sedative effect.
Detailed description
A trained member of the research team obtained a baseline The Modified Yale Preoperative Anxiety Scale(mYPAS) after obtaining consent. And corresponding study medication is administered about 30-40 minutes before the anesthesia induction.Vital signs were measured every 5 min after study medication administration.The sedation scores of the children were recorded with University of Michigan Sedation Scale (UMSS) every 10 minutes.The onset time of satisfactory sedation and parental separation anxiety scale was noted.Then recorded the degree of cooperation during inhalation anesthesia induction and recovery times.Moreover, recorded the pediatric anesthesia emergence delirium scale (PAED) during the recovery period.
Interventions
DRUGMidazolam
oral midazolam 0.5mg.kg-1 approximately 30-40 minutes before surgery using a computer-generated random number table.
DRUGDexmedetomidine
intranasal dexmedetomidine 2µg.kg-1 approximately 30-40 mins before surgery using a computer-generated random number table.
DRUGMidazolam and Dexmedetomidine
oral midazolam 0.5mg.kg-1 and intranasal dexmedetomidine 1ug.kg-1 approximately 30-40 mins before surgery using a computer-generated random number table.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The degree of cooperation during inhalation anesthesia induction | During inhalation anesthesia induction | Induction Compliance Checklist range from 0 through 10,and lower scores indicate the higher degree of cooperation during inhalation anesthesia induction |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The level of sedation | Each 10 minutes during the preoperative period | University of Michigan Sedation Scale: 0 -Awake/Alert 1 -Minimally Sedated: Tired/sleepy, appropriate response to verbal conversation and/or sounds. 2- Moderately Sedated: Somnolent/sleeping, easily aroused with light tactile stimulation. 3 - Deeply Sedated: Deep sleep, arousable only with significant physical stimulation. 4 - Unarousable. higher scores mean a higher levels of sedation. |
| The onset time of satisfactory sedation | During the preoperative period | The onset time of satisfactory sedation, defined as the time from drug administration to the time when the University of Michigan Sedation Scale reached two points. University of Michigan Sedation Scale: 0 -Awake/Alert 1 -Minimally Sedated: Tired/sleepy, appropriate response to verbal conversation and/or sounds. 2- Moderately Sedated: Somnolent/sleeping, easily aroused with light tactile stimulation. 3 - Deeply Sedated: Deep sleep, arousable only with significant physical stimulation. 4 - Unarousable. higher scores mean a higher levels of sedation. |
| Parental separation anxiety scale | During the preoperative period | A four-point parental separation anxiety scale as follows: 1. -Easy separation, 2. -Whimpers, but is easily reassured, not clinging, 3. \- Cries and cannot be easily reassured, but not clinging to parents, 4. \- Crying and clinging to parents. The scores of 1 and 2 signified acceptable separation whereas scores of 3 and 4 were classified as difficult separation. |
| Anxiety before induction of anesthesia | Before preoperative medication | The Modified Yale Preoperative Anxiety Scale: The 22-item measure has five behavioural categories: activity, emotional expressivity, alertness and arousal, vocalizations, and interaction with parents. Total scores range from 23.33 through 100 with higher scores indicating greater anxiety. |
| Pediatric anesthesia emergence delirium | Within up to 15-30 minutes after child's first eye opening in the postoperative period | The pediatric anesthesia emergence delirium scale consists of four items. Each item is scored 0-4 yielding a total between 0 and 20. The degree of emergence delirium increased directly with the total score.pediatric anesthesia emergence delirium scale ≥12 at any time indicates presence of emergence delirium. |
| Number of children with adverse effects | Up to 24 hours including preoperative, intraoperative, and postoperative periods | Number of children with adverse effects 1. Bradycardia and/or hypotension need for hemodynamic support 2. Desaturation is defined as Oxygen desaturation \<90% 3. Salivation 4. Any adverse effects requiring interventions |
| Recovery times | Within up to 30 minutes after child's first eye opening in the postoperative period | The time from discontinuation of sevoflurane to the first open eye of the children and to achieve aldrete≥9 |
