Furosemide Use to Fill the Bladder of Pediatric Females Awaiting Pelvic Ultrasound
Study Details
Study Description
Brief Summary
The purpose of this study is to investigate whether or not furosemide causes the bladder to fill faster than IV fluids alone so that a pelvic ultrasound exam can be performed.

Detailed Description
Trans-abdominal pelvic ultrasound is the standard imaging modality for diagnosis of ovarian torsion in the pediatric population, however this requires that the patient have a full bladder at the time of imaging. This study will investigate whether low dose furosemide in addition to IV fluid boluses may provide a fast, effective, and non-invasive means to fill the bladder of pediatric females awaiting pelvic US. The target population are females age 8 to 18 years seen in the emergency room at Connecticut Children's Medical Center who are undergoing a trans-abdominal pelvic ultrasound to assess for ovarian torsion. Enrolled patients will be randomized to the control (IVF bolus only) group vs. the intervention (IVF bolus + furosemide) group and will undergo point-of-care US (POCUS) and bladder scanner evaluation of the bladder every 30 minutes until the bladder is determined to be full.

Outcome Measures
Primary Outcome Measures
- The time from initiation of the intervention to the time that the bladder reaches large, ovoid shape on POCUS exam [Through study completion, about 3 hours]
Initiation of the intervention is defined as administration of furosemide vs. normal saline flush.
Secondary Outcome Measures
- The correlation between bladder volume as calculated on POCUS exam of a large, ovoid bladder and bladder volume as reported by bladder scanner [Through study completion, about 3 hours]
Measurements will be completed every 30 minutes through study completion
- Number and nature of all reports of adverse events related to furosemide administration [From time of intervention until final disposition, about 6 hours]
Adverse events include signs of severe dehydration, allergic reaction, and electrolyte abnormality
- The time from initiation of the intervention to the time of completion of successful radiology-performed pelvic US [About 3 hours]
- The time from initiation of intervention to the time of admission or discharge order placement [From time of intervention until final disposition, about 6 hours]
