Objective:
Ovarian hyperstimulation syndrome (OHSS) is a rare iatrogenic complication of ovarian stimulation usually occurring during the luteal phase or during the early part of pregnancy. OHSS is a potential complication of ovarian induction by almost every agent used for ovarian stimulation. Today, due to aggressive treatment protocols including the development of in vitro fertilization and cryopreservation with the goal of obtaining sufficient numbers of oocytes and embryos, an increased risk of developing OHSS is present. OHSS is now becoming increasingly more recognized due to the higher number of women undergoing assisted reproductive techniques.
Design:
Review of the literature regarding ovarian hyperstimulation syndrome.
Methods:
A review of the epidemiology, pathophysiology, risk factors, classification, clinical features, and treatment and prevention of OHSS.
Conclusion:
OHSS can be thought of as the loss of control over the hyperstimulation of the ovaries. Although the prevalence of the severe form of OHSS is small, it is important to remember that OHSS is usually an iatrogenic complication of a nonvital treatment that has the potential for a fatal outcome. Therefore, critical care physicians play an integral part in the care of these patients and therefore should be familiar with and recognize the various clinical manifestations and potential outcomes of this entity.
