Perinatal coagulopathies complicating fetal blood sampling
In a neonatal postmortem histological study of scalp stabs made with a fetal blood sampling blade the aponeurosis was punctured in up to 38% of cases even when it was more than 2 mm deep. This and other indirect and direct evidence discussed suggest that five of the seven reported cases of major bleeding after fetal blood sampling in labour were due to blood clotting defects and that these should be considered urgently in the management of future cases.
