Background At present, ovarian hyperstimulation syndrome (OHSS) is an uncommon and potentially life-threatening complication of ovarian stimulation. The ideal colloid solution for the treatment of patients with severe OHSS is still unknown. Human albumin, however, is considered the most 'physiologic' solution for this purpose and commonly used. However, severe life-threatening anaphylaxis has been reported with albumin infusion. The purpose of this study was to compare the efficacy and safety of hypertonic saline 3% for the treatment of severe OHSS rather than albumin. Patients and methods Over a period of 2 years, this randomized prospective study was conducted on 60 patients diagnosed with severe or critical OHSS admitted to Obstetric ICU of Ain-Shams University Hospitals. Patients were randomly allocated into two groups, each containing 30 patients. Group A (n=30) received 100 ml of albumin 20% over 4 h every 12 h plus conventional treatment according to the Ain Shams obstetric ICU protocol. Group N (n=30) received 500 ml of hypertonic saline 3% over 24 h (20 ml/h) plus conventional treatment. The efficacy of the study medications was compared in this study between the two groups in terms of daily urine output, serum creatinitine, percentage of occurrence established renal impairment, need of paracentesis, occurrence of established acute respiratory distress syndrome, and ICU length of stay. Results Significant difference was found regarding daily urine output among the study groups, with a significantly higher value (3350±142.6) in group N compared with group A (2150±133.4) associated with significant reduction in occurrence of established renal impairment in three cases in group A rather than 1 in group N. This is reflected by significant reduction in the length of ICU stay (3.1±1.1) in group N rather than group A (3.7±1.2). Conclusion The use of hypertonic saline 3% as a small-volume resuscitation is comparable to and effective and superior to albumin for the treatment of severe OHSS with regard to urine output, and may have a protective effect against occurrence of acute respiratory distress syndrome in such patients, but further studies are needed to prove that.
