[Maternal pulmonary oedema due to the use of atosiban in cases of multiple gestation].

Background: Nifedipine is used as a first choice tocolytic agent in many Dutch hospitals, but its use is discouraged in multiple gestations. Atosiban, a selective oxytocin receptor antagonist that rarely causes systemic side effects, is used as an alternative.

Case Description: A 32-year-old primigravida with spontaneous triplet pregnancy was admitted at 33 3/7 weeks for threatened preterm labour.
