- Primary Outcome Measures
Name Time Method Average of sum of the pain difference During hospitalization (around 48 hours post surgical procedure) The primary endpoint of the study is the average sum of the pain difference after study medication compared to the baseline by visual analogic scale from 0 to 10 cm, where 0 = no pain, and 10 = the worst imaginable pain)
- Secondary Outcome Measures
Name Time Method Average of visual analogic scale score During hospitalization (around 48 hours post surgical procedure) The average visual analogic scale score (visual analogic scale from 0 to 10 cm, where 0 = no pain and 10 = the worst imaginable pain) measured at rest and during handling in subsequent medication.
VRS (verbal scale and relief assessment pain) During hospitalization (around 48 hours post surgical procedure) VRS (verbal scale and relief assessment pain) where 0 = no pain relief, 1 = mild pain relief, 2 = moderate pain relief, 3 = good pain relief and 4 = excellent pain relief)
Assessment of complete pain relief by verbal scale and relief assessment pain (VRS) During hospitalization (around 48 hours post surgical procedure) Assessment of complete pain relief by verbal scale assessment of pain relief (VRS where 0 = no pain relief, 1 = mild pain relief, 2 = moderate pain relief, 3 = good pain relief, and 4 = excellent pain relief).
Need for medication of rescue During hospitalization (around 48 hours post surgical procedure) Number of patients who need medication of rescue (Patients who did not experience adequate pain relief with study medication who use additional analgesics, ie, rescue medication).
Assessment of satisfaction with treatment by the participant 14 days Assessment of satisfaction with treatment by the participant using a standard categorical rating scale: Patient-reported global evaluation of Eficacy (PGE) scale of 5-points where 0=poor, 1=fair, 2=good , 3=very good, and 5=excellent response to therapy).
Presence of adverse events 14 days
