SECONDARY outcome

Timeframe: From admission to discharge from PACU, up to 1 hour

Subjects with a Children's Hospital of Eastern Ontario Pain Scale score greater than 8 received rescue morphine doses of 25 ug/kg IV at 10-minute intervals until the score was less than 8. Minimum and Maximum values: minimum score: 4 \& maximum score: 13. The higher the score ( \> 8), the greater the pain appreciated by the patient.

SECONDARY outcome

Timeframe: From admission to PACU until room air saturations greater than or equal to 95% for 5 minutes

The subjects were then transported to the PACU with supplemental oxygen. Oxygen administration was continued after extubation until the patient was awake and could sustain room air saturations greater than 95% for 5 minutes. Duration of oxygen requirement was recorded as the time from tracheal extubation to cessation of oxygen supplementation in the PACU.

SECONDARY outcome

Timeframe: From admission to discharge from PACU, no time limit

Patients were considered ready for discharge from the PACU when they attained an Aldrete score of 9 or more and were free from pain, nausea, and vomiting. Aldrete score ranges form 0 to 10 and patients greater than 8 are deemed satisfactory for discharge from the PACU

SECONDARY outcome

Timeframe: From admission to discharge from PACU, no time limit

Patients in the PACU who were crying, restless, disoriented, unresponsive to the parent's voice, with non-purposeful thrashing movements requiring additional personnel to prevent bodily harm, and inconsolable even after parental presence, rescue analgesia and additional measures of comfort were considered to have emergence agitation.
