Oral Misoprostol for Cervical Priming Before Hysteroscopy

"Closed and numbered envelopes, containing a capsule with either 200mcg or 400mcg of misoprostol were randomly distributed to the patients. Each envelope was coded randomly and only the pharmaceutical department of the hospital knew the content of these envelopes and kept a list of their codes.~The misoprostol was administered by the floor nurse, per-os to the patient one hour before hysteroscopy with a small amount of water. The number on the envelope was noted by the nurse on the document relative to the patient. Hence, the patient, the physician performing the biopsy, the nurse and the research associate did not know the exact dose of misoprostol that was ingested by the patient."
