Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | The NRS was used to assess the resting pain intensity score within 72 hours after administration. The area under the curve (AUC0-72h) of the resting pain intensity score for the test drug and the placebo control were compared. | 72 hours | |
| Primary | The NRS was used to assess the resting pain intensity score within 48 hours after administration. The area under the curve (AUC0-48h) of the resting pain intensity score for the test drug and the hydrochloride ropivacaine injection were compared. | 48 hours | |
| Secondary | Compare the area under the time-curves of resting pain intensity scores for the test drug and the placebo control group from 0 to 24 hours and from 0 to 48 hours after administration. | from 0 to 24 hours and from 0 to 48 hours after administration. | |
| Secondary | Compare the area under the time-curves (AUC) of the resting pain intensity scores for the test drug and the hydrochloric acid ropivacaine injection from 0 to 24 hours and from 0 to 72 hours after administration. | from 0 to 24 hours and from 0 to 72 hours after administration. |
