ObjectiveTo compare the preemptive analgesia efficacy between two cycloxygenase-2 inhibitors, rofecoxib and etoricoxib in the ambulatory uterine evacuation patients.MethodsIn this randomized, double-blinded, placebo-controlled trial 60 patients were randomly divided into three groups and received a single dose of placebo, rofecoxib 50 mg, or etoricoxib 120 mg, respectively, before operation. Patient's visual analogue score (VAS) was rated postoperatively at 15 min, 30 min, 60 min, time-to-discharge, 6 h and 24 h. Fentanyl (in post-anesthesia care unit) and paracetamol (at home) were supplementary analgesics and the dosage was also recorded. Patient's satisfaction score was rated at 24 h postoperatively.ResultsEtoricoxib 120 mg and rofecoxib 50 mg were significantly superior to placebo at 6 h postoperatively (P < 0.05) while there was no significant differences of VAS at other time points. The amounts of Fentanyl used in post-anesthesia care unit were similar in three groups, but paracetamol taken at home was much less in rofecoxib group and etoricoxib group than in placebo group (P < 0.01). Compared to rofecoxib, etoricoxib provided better pain relief after discharge (P < 0.05). The overall pain management satisfaction score was significantly higher in etoricoxib group (96 +/- 7) than in other groups (P < 0.01).ConclusionPreemptive rofecoxib 50 mg and etoricoxib 120 mg may significantly decrease VAS at 6 h postoperatively, and reduce the usage of analgesics in ambulatory uterine evacuation patients. Etoricoxib 120 mg offeres better pain relief at home compared with rofecoxib 50 mg.
