Outcome Measures
Primary Outcome Measures
- Usage of Morphine, Post Surgery [0 hour to 48 hours after IP administration]
Change in the amount of morphine use (in milligrams) by subjects in each treatment group for a 48 hour period post IP administration
Secondary Outcome Measures
- Usage of Morphine, Post Surgery at other intervals [0 hour to 24 hours after IP administration ;24 hours to 48 hours after IP administration]
Change in the amount of morphine use (in milligrams) by subjects in each treatment group for 0-24 hours after IP administration.Change in the amount of morphine use (in milligrams) by subjects in each treatment group for 4-48 hours after IP administration.
- the Sum of Pain Intensity Differences in Pain Score Over 6、12、24、48 、12-24、24-48 Hours under static condition [48-hours]
Pain intensity will be evaluated using an 11-point (0-10) Numeric Rating Scale (NRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NRS.
- the Sum of Pain Intensity Differences in Pain Score Over 6、12、24、48 、12-24、24-48 Hours under moving condition [48-hours]
Pain intensity will be evaluated using an 11-point (0-10) Numeric Rating Scale (NRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NRS.
- Time to First Dose of Rescue Analgesia [0 hour to 48 hours after IP administration]
Time to first rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
- Frequency of Doses of Rescue Analgesia Utilized Per Subject, total consumption of morphine Rescue Analgesia Utilized Per Subject [0 hour to 24 hours after IP administration ;24 hours to 48 hours after IP administration ;0 hour to 48 hours after IP administration]
Rescue analgesia was available to subjects with inadequately controlled pain upon request.
- Total press times of PCA pump and effective press times of PCA pump [0 hour to 24 hours after IP administration ;24 hours to 48 hours after IP administration ;0 hour to 48 hours after IP administration]
Read and record the press times and effective press times from PCA
- Proportion of subjects who did not receive Rescue Analgesia [0 hour to 24 hours after IP administration ;24 hours to 48 hours after IP administration ;0 hour to 48 hours after IP administration]
Proportion of rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
- Participant ' satisfaction score for analgesia treatment [48-hours]
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.
- Investigator satisfaction score for analgesia treatment [48-hours]
Postoperative analgesia was evaluated by investigators. The scale ranges from 0 to 10, with 0 being dissatisfied and 10 being very satisfied
