Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the Sum of Pain Intensity Differences in Pain Score Over 24 Hours	Pain intensity will be evaluated using an 11-point (0-10) Numeric Pain Rating Scale (NPRS), with higher numbers indicating a higher pain intensity, administered over 24 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (24 hours) to yield values on the 0-10 NPRS.	24-hours
Secondary	the Sum of Pain Intensity Differences in Pain Score Over 6?12?12-24 Hours	time weighted sum of pain intensity differences (SPID) divided by a constant (6?12?12-24 hours) to yield values on the 0-10 NPRS.	6-hours?12-hours?12-24 hours
Secondary	Time of first use of remedial analgesic medication	The first time to use remedial analgesic medication for injection	24-hours
Secondary	Cumulative use of remedial analgesics from 0h to 24h	Cumulative use of remedial analgesic medication	24-hours
Secondary	Participant ' satisfaction score for analgesia treatment	Participants recalled the postoperative analgesia effect and rated their satisfaction on a scale of 0 to 10, with 0 representing dissatisfied and 10 representing very satisfied.	24-hours
Secondary	Investigator satisfaction score for analgesia treatment	Postoperative analgesia was evaluated by investigators.The scale ranges from 0 to 10, with 0 being dissatisfied and 10 being very satisfied.	24-hours
