TRIAL DESCRIPTION
Public title Comparison of diclofenac and paracervical block for pain relief during and after hysterosalpingography in women with infertility in South-South Nigeria: a randomised controlled trial
Official scientific title Comparison of diclofenac and paracervical block for pain relief during and after hysterosalpingography in women with infertility in South-South Nigeria: a randomised controlled trial
Brief summary describing the background and objectives of the trial Actual observations from our clinical practice in Nigeria indicate that infertility is a major burden on clinical service delivery, and the most frequent reason for gynaecological consultations in Nigeria is infertility. Hysterosalpingography is the primary investigative modality of choice for the evaluation of the uterine cavity, fallopian tubes, and adjacent peritoneal cavity. It is easy, has minimal complications, affordable, readily available, reliable, and does not require anesthesia. Its major shortcoming is pain. Many women experience mild to severe pain during and after hysterosalpingography. The objective of this randomised controlled trial was to compare the effectiveness of diclofenac and paracervical block with 2% lignocaine in pain reduction when undergoing hysterosalpingography in Bayelsa State, South-South Nigeria. This randomised controlled trial will be conducted at the radiology departments and infertility clinics of the Federal Medical Centre, Yenagoa and Niger Delta University Teaching Hospital, Okolobiri. 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 have intramuscular diclofenac 75 mg (3 ml), while the women in Group II will have paracervical block with 2% lignocaine. Following adequate counseling, written informed consent will be obtained from all the women. 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 diclofenac and lignocaine.

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Control Group Group I 75 mg of intramuscular diclofenac Stat/single dose 30 minutes before the procedure 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 have a combination of intramuscular diclofenac 75 mg (3 ml) and paracervical block with 3 ml of water for injection (placebo). Following adequate counseling, written informed consent will be obtained from all the women. The allocating team and the team performing the hysterosalpingography will be different, to help prevent selection bias. 260 Active-Treatment of Control Group
Experimental Group Group II Paracervical block with 2% lignocaine five minutes before grasping the anterior lip of the cervix. Stat/single dose 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 II will have 3 ml of intramuscular water for injection and paracervical block with 2% lignocaine.
