title: Current practices regarding newborn intracranial haemorrhage and obstetrical care and mode of delivery of pregnant haemophilia carriers: a survey of obstetricians, neonatologists and haematologists in the United States, on behalf of the National Hemophilia Foundation's Medical and Scientific Advisory Council.
abstract: We undertook this survey to determine institutional practices of obstetricians, neonatologists and haematologists regarding care of pregnant haemophilia carriers and newborns with haemophilia and intracranial haemorrhage (ICH). Our purpose was also to determine whether institutions had written guidelines to manage such patients. Questionnaires were sent to 1000 obstetricians and through the Haemophilia Treatment Centres (HTC) to 180 paediatric haematologists and 180 neonatologists, each representing an institution. Twenty-three per cent of obstetricians, 22% of neonatologists and 16% of paediatric haematologists returned completed surveys. Over 94% of the respondents had no written guidelines for management of pregnant haemophilia carriers or their newborns or for neurologic assessment of newborns. For known haemophilia carriers, 57% of the obstetricians routinely preferred vaginal delivery and 11% preferred caesarean section. Availability of perinatal services influenced prenatal management (P < 0.05). In term newborns with documented ICH, only 23% of neonatologists would evaluate for haemophilia, whereas in pre-term newborns with ICH, this number dropped even further to 3%. For all newborns with haemophilia, 40% preferred routine administration of clotting factor concentrates (CFC) immediately following birth to offset the trauma of delivery and 89% of paediatric haematologists favoured early prophylaxis with CFC. Guidelines are needed for management of pregnant haemophilia carriers as well as newborns with haemophilia. Physicians need to be made aware that ICH may be a presenting sign of haemophilia in both term as well as pre-term newborns, so that appropriate therapy can be instituted early in the event of a bleed.
