Pain relief in hysterosalpingography. A comparison of analgesics

Hysterosalpingography provides important information in the evaluation of infertility but is generally considered an uncomfortable and painful procedure. We evaluated various analgesics for decreasing or eliminating the discomfort from this procedure. Two types of analgesia were required to give maximum pain relief during and after the examination in the 180 patients evaluated. The best results were achieved with a combination of naproxen sodium, 550 mg, given orally two hours before the examination, and 20% benzocaine, applied to the cervix.
