Study ObjectiveTo assess whether vaginal misoprostol or oral nonsteroidal anti-inflammatory drugs (NSAIDs) reduce pain during and 30 minutes after hysterosalpingography (HSG).DesignRandomized prospective, controlled, parallel-group study (Canadian Task Force classification I).SettingUniversity teaching hospital.PatientsOne hundred sixty-eight women with primary infertility who underwent HSG for evaluation of infertility.InterventionsPatients were randomly assigned to 1 of 3 groups. Group 1 received 200 μg misoprostol vaginally 6 hours before HSG; group 2, 50 mg diclofenac potassium orally 45 to 60 minutes before HSG; and group 3, no medication. The primary outcome of the study was to evaluate the severity of pain during and 30 minutes after the procedure using a visual analog scale (VAS) ranging from 1 (very favorable) to 10 (very unfavorable). The secondary outcomes were to assess the rate of completion and the vasovagal effects including nausea, vomiting, sweating, weakness, syncope, hypotension, and bradycardia.Measurements And Main ResultsThere was no statistically significant difference in the median (25%-75%) VAS pain scores between women administered vaginal misoprostol (median, 6.7 cm; range, 4.7-9 cm) and the control group (median, 6.7 cm; range, 4.6-8.8 cm) during the HSG. However, women in the NSAID group (median, 5.5 cm; range, 3-7.6 cm) reported less pain than did those in the misoprostol group (p = .009) and the control group (p = .03). At 30 minutes after HSG, there was no significant difference in the median VAS pain scores between patients administered NSAIDs (median, 2.3 cm; range, 1.4-4.2) or misoprostol (median, 2.3 cm; range, 1.2-4.4) and the control group (median, 2.2 cm; range, 1.3-4.4).ConclusionsThere is no benefit in terms of pain reduction with the use of misoprostol during HSG or at 30 minutes after the procedure. However, NSAIDs are associated with pain relief during the HSG procedure.Copyright © 2014 AAGL. Published by Elsevier Inc. All rights reserved.
