Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | the difference in average pain scores | 1 year | We will test the difference in average pain scores between the groups in a non-inferiority model. All pain scores obtained during the initial two postoperative hours will be averaged and compared between the groups. The non-inferiority delta will be defined a priori as no worse than 1.5 points in average pain score. Overall alpha will be 0.05. NRS Scale from 0-10, zero is no pain. |
| Primary | the dependent categorical variable of time-to-discharge readiness | 1 year | The secondary analysis will compare the dependent variable of time-to-discharge from postanesthesia care unit (PACU) readiness at 60 mins (yes/no) between the two study groups and will be reported as number (proportions). We will also record the time from arrival until discharge from PACU reported as the median \[interquartile range\] time in each group. Overall alpha will be 0.05. |
| Other | comparison of the average sedation scores 20 minutes after admission to the recovery room | 1 year | We will compare average sedation scores 20 minutes after admission to the recovery room between the groups using a two-sided Student's t-test. We will also compare the proportion of patients who required rescue analgesics (tramadol) in PACU between the two groups, using the Fisher's exact test. |
