Benzocaine Versus Placebo Spray for Pain Relief at Hysterosalpingogram

Status Completed

Clinical Trial Summary

The objective of this study is to assess the utility of benzocaine spray versus a placebo spray in alleviating pain during and after hysterosalpingogram (HSG).

Clinical Trial Description

Hysterosalpingography (HSG) is a radiographic evaluation during which a radio-opaque medium is inserted through the cervical canal in order to define the size and shape of the uterine cavity and patency of the fallopian tubes. The utility of HSG is an integral part of the evaluation of infertile women for intrauterine pathology. In some cases, HSG can a painful procedure. Poor pain control can limit the quality of the study due to inability to complete the procedure in cases of extreme discomfort. There is little consensus regarding pain control during HSG, although a number of approaches have been studied. Patients undergoing HSG are typically advised to premedicate with ibuprofen, which is consistent with the current standard of care. This study will assess pain control using a benzocaine spray (in addition to ibuprofen) in patients undergoing routine HSG at the Hospital of the University of Pennsylvania. All patients who present to the Hospital of the University of Pennsylvania for HSG will be eligible for the study. Benzocaine spray versus a placebo spray will be applied to a tenaculum (a surgical hooklike instrument used to grasp and hold the cervix). The tenaculum will then be applied to the cervix prior to HSG and pain relief will be assessed at 3 time intervals: 0, 5, and 30 minutes. The primary outcome is the mean difference in patients pain score and will be measured using the Visual Analogue Scale (VAS) which has been shown to be a valid and reliable scale. The secondary outcome will assess patient satisfaction in each group using a validated patient satisfaction survey. The study design will be prospective, randomized, placebo controlled, and double blinded. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
