Abstract
BACKGROUND: Prevention of severe Ovarian Hyperstimulation Syndrome (OHSS), a potentially fatal complication of controlled ovarian hyperstimulation has been the aim of all fertility experts. Various pharmacologic and non-pharmacologic interventions have been instituted but the results have been conflicting. These preventive strategies were administered in isolation or as a combination of few aiming to eliminate this iatrogenic sequel. This study aimed to eliminate severe OHSS by multipronged approach incorporating almost all preventive modalities available in patients at high risk for this dreadful complication. METHODS: It was a prospective observational study wherein 112 high risk patients planned for IVF were studied. The multipronged approach was in the form administering calcium gluconate infusion, cabergoline, albumin infusion, GnRH antagonist in luteal phase in addition to elective cryopreservation of embryos. The primary outcome measure was incidence of severe OHSS in the study group and the rate of hospitalisation. The secondary outcome measure was the number of days required for complete recovery and resolution of signs and symptoms. RESULTS: Out of the 112 high risk patients only one patient (1/112; 0.9%) developed severe OHSS with an overall incidence of 0.095% of severe OHSS in all the cycles. There was no biochemical or haematological derangement in any of the high risk patients. CONCLUSION: Although this is the first study evaluating the multipronged approach in preventing the dreaded complication of severe OHSS, it does add to the knowledge that targeting the various pathophysiological pathways at different time frames will bring about prevention of OHSS but further randomised studies may reveal superiority of one intervention over the other.
