Background: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life-threatening disease process, which may occur in healthy young women undergoing controlled ovarian hyperstimulation for assisted reproduction. As the treatment is largely empirical, prevention forms the mainstay of management. Objective: The present study was aimed to evaluate the effectiveness of intravenous (IV) calcium gluconate infusion in comparison to the dopamine agonist cabergoline (Cb2) in preventing OHSS in high risk patients undergoing assisted reproductive technique cycles. Materials and Methods: It was a comparative study wherein the 202 high risk patients undergoing in vitro-fertilization over a period of 18 months after meeting the strict inclusion and the exclusion criteria, were randomly divided into two groups (98 subjects in Group I and 104 in Group II). Women in Group I were administered IV calcium gluconate while the remaining 104 received the dopamine agonist Cb2. The 104 patients belonging to Group II were started Cb2 0.5 mg/day from the day of ovulation trigger and continued until the next 8 days while the 98 high risk patients from Group I were infused with 10 ml of 10% calcium gluconate solution in 200 ml physiologic saline within 30 min of ovum pick up and continued thereafter on day 1, day 2 and day 3. Results: The occurrence of OHSS was seen in only nine patients (in the calcium infusion group, when compared with 16 patients (9.2% vs. 15.4%) who were administered Cb2, but it was not statistically significant. However, only one had severe OHSS in Group I, whereas two women were diagnosed as severe OHSS belonging to the Cb2 arm. Conclusion: Our results document that calcium infusion can effectively prevent severe OHSS and decreases OHSS occurrence rates when used for high-risk patients, but does not suggest its superiority over Cb2. With comparable success rates, either of them can be employed as a preventive strategy for OHSS.
