TRIAL DESCRIPTION
Public title Effect of intramuscular hyoscine-N-butyl bromide on tubal spasm and pain perception in infertile women undergoing hysterosalpingography: a randomised controlled trial
Official scientific title Effect of intramuscular hyoscine-N-butyl bromide on tubal spasm and pain perception in infertile women undergoing hysterosalpingography: a randomised controlled trial
Brief summary describing the background and objectives of the trial Infertility is defined as the failure of a couple to conceive ≥12 months of regular unprotected intercourse. It affects 6.6% and 26.4% of reproductive-aged women. Tubal abnormalities account for 30–40% of cases of infertility. Hysterosalpingography is considered the initial diagnostic tool for assessment of tubal patency. Additionally, it can be useful in the diagnosis of intrauterine pathology. The objective of this study is to determine the efficacy of oral hyoscine-N-butyl bromide in relief of tubal spasm and pain perception during hysterosalpingography. This randomised controlled trial is being conducted at the radiology departments and infertility clinics of the Federal Medical Centre, Yenagoa and Niger Delta University Teaching Hospital, Okolobiri, both in Bayelsa State, Nigeria. Three hundred and eighty infertile women undergoing hysterosalpingography will be enrolled in the study. They will be assigned into two groups by computer generated randomisation. Women in Group I will receive intramuscular hyoscine-N-butyl bromide 20 mg (1 ml), while the women in Group II will receive placebo with 1 ml of water for injection. The allocating team and the team performing the hysterosalpingography will be different, to help prevent selection bias. Infertile women referred for hysterosalpingography, and women that gave consent and completely filled the consent/questionnaire form will be included in the study. Exclusion criteria included abnormal uterine/vaginal bleeding before the procedure, on-going menstruation, pregnancy, discharge on inspection of the cervix, cervical stenosis/cervical pathology, evidence of pelvic inflammatory disease, previous history of contrast hypersensitivity, history of allergy to hyoscine-N-butyl bromide, and all patients that declined consent.
