Trial Outcomes & Findings for Tramadol Versus Placebo in the Management of Postoperative Pain Following Bunionectomy (NCT NCT03290378)

NCT ID: NCT03290378

Last Updated: 2020-03-19

Results Overview

Pain intensity was recorded using the Numerical Pain Rating Scale (NPRS) from 0 to 10, where 0 was no pain and 10 was the worst pain imaginable at hrs: .5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48. As higher pain scores indicate worse pain, a negative Pain Intensity Difference (PID) indicates less pain (improvement from baseline). Thus, SPID scores are expected to be negative if a patient's pain decreases over time, with the lower SPID values indicating greater reduction in pain intensity.

PRIMARY outcome

Timeframe: 48 hours post first dose

Population: One patient was randomized to tramadol 25 mg but received tramadol 50 mg in error.

Pain intensity was recorded using the Numerical Pain Rating Scale (NPRS) from 0 to 10, where 0 was no pain and 10 was the worst pain imaginable at hrs: .5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48. As higher pain scores indicate worse pain, a negative Pain Intensity Difference (PID) indicates less pain (improvement from baseline). Thus, SPID scores are expected to be negative if a patient's pain decreases over time, with the lower SPID values indicating greater reduction in pain intensity.
