Perinatal management of trisomy 18: a survey of obstetricians in Australia, New Zealand and the UK

Abstract

OBJECTIVE: The objective of this study was to explore the attitudes of obstetricians in Australia, New Zealand and the UK towards prenatally diagnosed trisomy 18 (T18). METHOD: Obstetricians were contacted by email and invited to participate in an anonymous electronic survey. RESULTS: Survey responses were obtained from 1018/3717 (27%) practicing obstetricians/gynaecologists. Most (60%) had managed a case of T18 in the last 2 years. Eighty-five per cent believed that T18 was a 'lethal malformation', although 38% expected at least half of liveborn infants to survive for more than 1 week. Twenty-one per cent indicated that a vegetative existence was the best developmental outcome for surviving..
