A prospective, randomized, double-blind and placebo-controlled study was
conducted to assess the effectiveness of i.v. administration of 6%
hydroxyethyle starch solution (HES) in preventing moderate and severe
ovarian hyperstimulation syndrome (OHSS) in patients in an in-vitro
fertilization programme. A total of 101 women who had serum oestradiol
concentrations >1500 pg/ml and/or more than 10 follicles on day of human
chorionic gonadotrophin (HCG) administration were recruited into two
groups: HES group (n = 51) received 1000 ml 6% HES; and the placebo group
(n = 50) received 1000 ml of sodium chloride 0.9% solution at the time
shortly after embryo transfer. Follow-up examinations 7 +/- 1 and 14 +/- 1
days after embryo transfer included transvaginal ultrasound (diameters of
each ovary and maximum cysts, number of cysts, ascites), blood tests (serum
oestradiol, progesterone, beta-HCG, C-reactive protein, blood count, plasma
proteins, electrolytes, kidney function tests) and evaluation of abdominal
pain, nausea, diarrhoea, abdominal swelling and weight gain. Only one
moderate OHSS developed in the HES group whereas seven moderate-severe
cases were observed in the placebo group (P = 0.031). Furthermore, serum
oestradiol concentration, leukocyte count, increase in abdominal
circumference and weight gain 14 days after embryo transfer were
significantly higher in the placebo group. There were no differences
between the two groups in terms of age, oestradiol concentration and number
of follicles at time of HCG injection. Administration of 6% HES prevents
the development of moderate-severe OHSS in risk patients.
