BULLET: Bladder Ultrasound Limits Length (of Time), Expedites Treatment

Brief Summary

Detailed Description

In this study, we will enroll female pediatric emergency department (ED) patients presenting with a diagnosis of abdominal pain who may have a transabdominal pelvic ultrasound ordered by their treating physician (or nurse practitioner). In order to maximize the visualization of organs deep within the pelvis such as the ovaries and uterus, the patient's bladder must be full. The current practice at our institution, as well as numerous others, is to have a bladder catheter placed immediately when a transabdominal pelvic ultrasound is ordered, and then to fill the bladder in a retrograde manner in order to provide enhanced visualization of the pelvic structures. The process of inserting a bladder catheter into a pediatric patient is an invasive procedure which can be traumatic and painful to the patient. Additionally, if the patient's bladder is already full, this procedure may be unnecessary. In this study, a point-of-care bladder ultrasound will be performed, upon enrollment of a patient by a study bedside sonographer (our pediatric emergency department nurse practitioners), to assess degree of bladder fullness. This measurement will then be repeated serially while the patient is receiving hydration and the ultrasound will be performed when the bladder is full. We hypothesize that this work flow will result in an equivalent time to transabdominal pelvic ultrasound completion and will reduce the number of potentially traumatic and painful, invasive urethral bladder catheterizations.

Primary Outcomes

Secondary Outcomes

• Pain of Bladder Ultrasound vs. Pain of Bladder Catheter as Measured by Verbal Numerical Rating Scale (VNRS)(When bladder ultrasound performed OR when urinary catheter placed to time of completion of pelvic ultrasound, up to 180 minutes)
