Brief Summary
Hysterosalpingography (HSG) is commonly performed during infertility evaluation and may cause pain during cervical manipulation, uterine distension, and contrast-medium injection. This prospective, randomized, three-arm controlled trial will compare three pain-control approaches during HSG: no analgesic premedication, rectal indomethacin administered before the procedure, and paracervical block with lidocaine. Eligible women scheduled for diagnostic HSG will be randomized in a 1:1:1 ratio. The primary outcome will be participant-reported pain during contrast-medium injection measured using an 11-point Numeric Rating Scale (NRS) ranging from 0 to 10. Secondary outcomes will include pain during other procedural stages, immediate and 30-minute post-procedural pain, preprocedural anxiety, anticipated pain, rescue analgesic requirement, participant satisfaction, and adverse events.

Outcome Measures
Primary Outcomes (1)
Pain Intensity During Contrast-Medium Injection Measured Using the Numeric Rating Scale
Participant-reported pain intensity will be measured using an 11-point Numeric Rating Scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
During HSG, immediately after contrast-medium injection
Secondary Outcomes (12)
Pain Intensity During Speculum Insertion
During HSG, immediately after speculum insertion
Pain Intensity During Cervical Grasping
During HSG, immediately after tenaculum application or cervical grasping
Pain Intensity During Cannula or Catheter Placement
During HSG, immediately after cannula or catheter placement
Pain Intensity During Cervical Traction
During HSG, immediately after cervical traction
Immediate Post-Procedural Pain Intensity
Within 5 minutes after completion of HSG
- +7 more secondary outcomes
Study Arms (3)
No Premedication
NO INTERVENTIONParticipants will undergo standard hysterosalpingography without analgesic or local anesthetic premedication.
Rectal Indomethacin
ACTIVE COMPARATORA 50 mg indomethacin suppository will be administered rectally 30 minutes before hysterosalpingography.
Paracervical Block With Lidocaine
ACTIVE COMPARATORA paracervical block will be performed using 2% lidocaine. Five milliliters of 2% lidocaine will be administered at the 4 o'clock position and 5 mL at the 8 o'clock position of the cervix, for a total volume of 10 mL and a total lidocaine dose of 200 mg. Injection depth will be approximately 1.5 to 3 cm. Hysterosalpingography will begin 5 minutes after completion of the paracervical block.
Interventions
A 50 mg indomethacin suppository will be administered rectally 30 minutes before hysterosalpingography.
A paracervical block will be performed using 2% lidocaine. Five milliliters of 2% lidocaine will be administered at the 4 o'clock position and 5 mL at the 8 o'clock position of the cervix, for a total volume of 10 mL and a total lidocaine dose of 200 mg. Injection depth will be approximately 1.5 to 3 cm. Hysterosalpingography will begin 5 minutes after completion of the paracervical block.
