Brief Summary
Oculocardiac reflex (OCR) is usually happening in pediatric strabismus surgery and observed just when the surgent pulls the ocular muscles. The reflex is one of the trigemino-vagal reflexes, and causes bradycardia, arrhythmia, and even cardiac arrest during eye surgery. Premedication for relaxation with drugs like hydroxyzine dihydrochloride or midazolam before surgery of the pediatric population is often used in Turkey, although it is not recommended in foreign countries. Some recent studies showed that when midazolam and hydroxyzine dihydrochloride used together not only, they lessen agitation before surgery but also they prevent emergence agitation. The primary aim of this prospective observational study is to show the effect of hydroxyzine dihydrochloride on preventing the pediatric patient from Oculocardiac reflex related to strabismus surgery.

Outcome Measures
Primary Outcomes (4)
Heart Rate-1
The lowest heart rate observed from EKG monitorization at the "time-out" after the anesthesia induction, and just before the surgery starts. Heart rate-1 is a data, not an assessing change, which is recoded during the "time-out". "The time-out" is when the patient's name, the procedure, the surgent name is repeated before the operation starts.
1 minute, at the "time out", through study completion an average of 6 months
Heart Rate-2
The heart rate observed from EKG monitorization at the time operator warns the investigator just before the traction of the orbital muscle. Heart rate-2 is a data, not an assessing change, which is recorded during the operation at the time operator warns. The heart rate observed from EKG monitorization, before every orbital muscle traction at the time the operator's warning before traction.
1 minute, at the strabismus surgery operation, through study completion an average of 6 months
Heart Rate-3
The lowest heart rate observed from EKG monitorization, after every orbital muscle traction within 120 seconds. Heart rate-3 is a data, not an assessing change, which is recorded within 120 seconds after traction applied.
within 120 seconds after the orbital muscle traction, at the strabismus surgery operation, through study completion an average of 6 months
Number of Observed Oculocardiac Reflex(OCR)
The OCR is a heartbeat anomaly(bradycardia, any arrhythmia, or cardiac arrest) associated with traction applied to the extraocular muscles during strabismus surgery. The specific criteria were as follows: the lowest heart rate observed within 120 seconds from EKG monitorization, after every orbital muscle traction, was less than 20% of the heart rate observed directly preceding traction of the orbital muscle. Additionally, any kind of arrhythmia or cardiac arrest occurrence within 120 seconds after orbital muscle traction was also defined as an OCR.
2 minutes, at the strabismus surgery operation after recording Heart Rate-3, through study completion an average of 6 months
Secondary Outcomes (1)
Ramsay Sedation Score
After patient transferred into the operation theatre and before anesthesia induction, through study completion an average of 6 months
Other Outcomes (2)
Number of Orbital Muscles of the Participants With Different Considerations Taken With Respect to the Treatment of OCR
within 5 minutes after defining the OCR occurrence, at the strabismus surgery operation, through study completion an average of 6 months
The Orbital Muscle Name Which OCR Occurred During it's Traction
within 5 minutes after defining the OCR occurrence, at the strabismus surgery operation, through study completion an average of 6 months
Study Arms (3)
Midazolam
Demizolam, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with cherry juice of maximum 5 ml. in Yeditepe University Hospital to the pediatric patients by the anesthesiologists. In all groups patients are not selected to the groups and premedication and doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
Midazolam&Hydroxyzine dihydrochloride1/2
Midazolam and Hydroxyzine dihydrochloride, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with hydroxyzine dihydrochloride (dose of 0.5 mg/kg) in Yeditepe University Hospital to the pediatric patients by the anesthesiologists. In all groups patients are not selected to the groups and premedication doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
Midazolam&Hydroxyzine dihydrochloride
Midazolam and Hydroxyzine dihydrochloride, once on the operation day, usually ordered 15 minutes before strabismus operation by another anesthesiologist who is charged to perform anesthesia who is not related with the trial.The maximum dose of 0.5 mg/kg midazolam is given orally with the maximum dose of 1mg/kg hydroxyzine dihydrochloride in Yeditepe University Hospital to the pediatric patients by the anesthesiologists. In all groups patients are not selected to the groups and premedication doses are not given by the investigator, they grouped according to the premedication given by the anesthesiologists, after the operation retrospectively.
Interventions
Demizolam 15mg/ml ampules, given orally with cherry juice
Atarax 2mg/ml syrup, given orally
