  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Heart Rate (HR)   [ Time Frame: Heart rate was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. Heart rate was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU). ]

2.  Primary:   Systolic Blood Pressure (SBP)   [ Time Frame: Systolic blood pressure (SBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. SBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU). ]

3.  Primary:   Diastolic Blood Pressure (DBP)   [ Time Frame: Diastolic blood pressure (DBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. DBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU). ]

4.  Secondary:   Incidence of Emergence Agitation (EA)   [ Time Frame: The highest PAED score for each patient within the first 30 minutes after waking up was recorded. ]
