Intravenous albumin administration in high-risk patients for prevention of severe OHSS occurrence.
Severe OHSS occurrence.
Eight eligible randomized controlled trials were identified (n = 1,199 patients) that offered data for statistical pooling. No statistically significant difference in the occurrence of severe OHSS in patients who received intravenous albumin (n = 595) and those who did not (n = 604; odds ratio [OR], 0.80; 95 % confidence interval [CI], 0.52–1.22) was detected. Moreover, no statistically significant differences were present regarding the probability of pregnancy (OR, 0.83; 95 % CI, 0.64–1.07) and first trimester pregnancy loss (OR, 1.44; 95 % CI, 0.73–2.85) between patients who received intravenous albumin and those who did not.
Based on the currently best available evidence, intravenous albumin administration in high-risk patients does not appear to reduce the occurrence of severe OHSS. This finding should be considered when implementing strategies for severe OHSS prevention.
