This is an applied, mono-blind, trial clinical study performed to assess the effectiveness of pethidine hydrochloride and diclofenac sodium on pain relief after cesarean in Shahid Mostafa Khomaini hospital of Ilam (in 2006). During the trial, 100 women undergoing cesarean (50 women in pethidine group and 50 women in diclofenac group) were observed and assessed. While the patient had pain, intra muscular analgesic (in accordance with the group) was injected for her, then she was assessed by Visual Analog Scale, V.A.S, and compared. The data was analyzed by chi- square, Mann-Whitney, ranked- regression and Tstudent tests.

According to results, Mann-Whitney test showed that pain severity in diclofenac sodium was lower than that in pethidine group. There was a singnificant decrease of pain, statistically, in the second and third 20 minutes and 120 minutes after the intervention (p<0.001).

Considering the findings of this research, diclofenac sodium (non-narcotic analgesic) is more effective than pethidine hydrochloride (narcotic analgesic) to relieve the pain after surgical operations amony patients.
