ListOutcomeTime frameDescription
PrimaryExtubation Time After Intranasal Dexmedetomidine Premedication1 daysThe times from stopping anesthetic infusions to adequate ventilation, consciousness and extubation after intranasal dexmedetomidine or placebo administration
SecondaryModified OAA/S Scores of Patients Receiving Intranasal Placebo or Dexmedetomidine1 days
Modified Observer's Assessment of Alertness/Sedation scale (OAA/S) scores and 4 point anxiety score of patients receiving intranasal placebo or dexmedetomidine. Modified Observer's Assessment of Alertness/Sedation Scale: 6 Appears alert and awake, responds readily to name spoken in normal tone 5 Appears asleep but responds readily to name spoken in normal tone 4 Lethargic response to name spoken in normal tone 3 Responds only after name is called loudly or repeatedly 2 Responds only after mild prodding or shaking 1 Does not respond to mild prodding or shaking 0 Does not respond to noxious stimulus.
SecondaryHeart Rate (HR) of Patients Receiving Intranasal Placebo or Dexmedetomidine1 dayHeart rate (HR) of patients receiving intranasal placebo or dexmedetomidine. HR was monitored in the study.
SecondaryNumber of Participants With Anxiety Score >21 day
satisfaction using a 3-point satisfaction score (1 = highly satisfactory, 2 = acceptable, and 3 = unacceptable) anxiety levels using a 4-point anxiety score (1 = combative, 2 = anxious, 3 = calm, and 4 = amiable) were collected before intranasal drugs and at pre-induction. Anxiety score \>2 was considered to be better for the patient.
SecondaryAnxiety Score of Patients Receiving Intranasal Placebo or Dexmedetomidine1 day4-point anxiety score: 1. = combative 2. = anxious 3. = calm 4. = amiable. Anxiety score \>2 was considered to be better for the preoperative patients.
SecondarySystolic Blood Pressure(SBP)of Patients Receiving Intranasal Placebo or Dexmedetomidine1 daySystolic blood pressure(SBP)of Patients Receiving Intranasal Placebo or Dexmedetomidine.
SecondaryNumber of Participants With Satisfaction Score <21 day
Patient satisfaction scores using a 3-point satisfaction score (1 = highly satisfactory, 2 = acceptable, and 3 = unacceptable) were collected when patients were discharged from the post-anesthesia care unit (PACU). Satisfaction score \<2 was considered to be better for the patient
SecondaryPerioperative Bradycardia Episodes1 dayBradycardia was defined as heart rate (HR) \<45 bpm for more than 10 s.
SecondaryPerioperative Tachycardia Episodes1 dayTachycardia was defined as heart rate (HR) \>100 bpm for more than 10 s.
SecondaryPerioperative Hypotension Episodes1 dayHypotension was defined as systolic blood pressure (SBP) decreased more than 30% of the pre-operative value for more than 1 min.
