Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | The Percentage of Patients Requiring at Least One Medical Intervention for Respiratory Events | Time from entering the PACU until the patient leaves,approx 1 hour. | The medical interventions included instrumentation of the airway, bag/mask ventilation, and/or drug administration (succinylcholine, albuterol, or naloxone), which were classified as major medical interventions. The medical interventions also included repositioning of the child's airway, chin lift/jaw thrust maneuvers, and/or escalating to an oxygen mask, which were classified as minor medical interventions. Since oxygen by nasal cannula was delivered to all children recovering from anesthesia, escalating to an oxygen mask implied the patient need but higher concentration of oxygen to maintain SpO2 ≥ 95%. |
| Secondary | The Median Survival Time for CHEOPS Score > 6. | Time from entering the PACU until the patient leaves,approx 1 hour. | Pain was assessed and recorded through the East Ontario children's hospital pain score (CHEOPS).When the CHEOPS\>6,We thought it is painful. Comparing the median survival time (the time corresponding to pain percentage of 50% in two groups) for CHEOPS\>6 in two groups. |
