This procedure describes the general clinical procedures that need to be undertaken within the Assisted Conception Service (ACS), Glasgow Royal Infirmary (GRI).
OHSS is self-limiting and usually resolves spontaneously within several days. However, it may persist for longer particularly in those women receiving assisted conception treatment. Mild OHSS is common – it occurs in up to 33% of IVF treatment cycles. Moderate to severe OHSS is rare (occurs in 3 to 8% of IVF treatment cycles) but is life threatening. The clinical course is, however, a continuum of scope and severity.
Clinicians should be aware and women informed that pregnancies complicated by OHSS may be at increased risk of pre-eclampsia and preterm delivery. Those most at risk of suffering from OHSS are young women (<30 years of age) with a low BMI undergoing ovarian hyperstimulation treatment. Other predisposing factors include:
- The presence of multiple follicles/oocytes
- Treatment with hCG (to mature oocytes during ovarian hyperstimulation)
- Previous OHSS
In all cases, the Assisted Conception Service team at GRI must be:
- informed of the diagnosis using the proforma
- involved in clinical decisions and supervision of continuing care.
