Predictors of Paracentesis in Women with Severe Ovarian Hyperstimulation Syndrome: A Retrospective Cohort Study

Background: To identify predictors of paracentesis in women with severe ovarian hyperstimulation syndrome (OHSS). Methods: In a retrospective cohort study, we assessed patient characteristics and outcome measures of women with severe OHSS Golan grade II/III from 1996 to 2010 using univariate and multivariate analyses with the number of paracenteses as the main outcome. Results: Three hundred ninety four women with OHSS Golan grade II (n = 40) and grade III (n = 354) were included in the study. Paracentesis was performed in 108/394 (27%) of these women. One paracentesis was performed in 63 (16%), 2 paracenteses in 26 (6%), and ≥3 paracenteses 19 (5%) women, respectively. No thrombotic or cerebrovascular morbidity occurred. The mortality of the cohort was 0/394 (0%). In a univariate analysis, late onset OHSS (p = 0.02), pregnancy (p Conclusion: Alanine aminotransferase and hematocrit at initial presentation are independent predictors of paracentesis.
