What is Known:
• The causes for neonatal thrombocytopenia (NT) are well known.
• The effects of platelet transfusions (PT) and its indications are still a matter of debate and recommendations differ widely.
What is New:
• The duration of NT is positively related to the severity of NT and the number of subsequent PT.
• The mortality rate is not associated with the severity of NT but increases with increasing numbers of PT and in the case of relevant intraventricular hemorrhage (≥ grade II), PT does not influence the mortality rate.
