title: Use of Point-of-Care Ultrasound for the Diagnosis of Ovarian Hyperstimulation Syndrome.
abstract: BACKGROUND
  Ovarian hyperstimulation syndrome (OHSS) occurs when ovaries are overstimulated and enlarged due to fertility treatments resulting in a shift of serum from the intravascular space to the third space, mainly the abdominal cavity. It is the most serious complication of ovarian hyperstimulation for assisted reproduction.
  
  
  METHODS
  We present the case of a 40-year-old woman who presented with abdominal bloating and nausea 2 weeks after undergoing in vitro fertilization (IVF); she was diagnosed by an outside radiology ultrasound as having a ruptured ovarian cyst. A point-of-care emergency ultrasound performed by the emergency physician made the diagnosis of ovarian hyperstimulation syndrome. This led to more expedient management and obstetrical consultation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Abdominal bloating and nausea are common presenting complaints in pregnant women. OHSS is a rare but potentially fatal complication of IVF. Recognition and early diagnosis by the emergency physician can lead to appropriate intervention and consultation.
