Trial Outcomes & Findings for Benzocaine Versus Placebo Spray for Pain Relief at Hysterosalpingogram (NCT NCT01925469)
NCT ID: NCT01925469
Last Updated: 2017-04-28
Results Overview
The primary outcome is the difference in pain score using a validated visual analog scale before the procedure, which is designated as the pre-procedure (or baseline) pain score to the maximum pain during procedure (designated as time 0) These two pain scores will be subtracted and the change in pain score will be reported. The validated visual analog scale allows patients to report pain on a scale of 0 to 100 mm long. At the beginning and at the end, there are two descriptors representing extremes of pain (i.e. no pain = 0 and extreme pain = 100). The patient rated her pain by making a vertical mark on the 100-mm line. The measurement in millimeters was converted to the same number of points ranging from 0 to 100 points. There are no subgroups.
