The haemorrhagic disorders are particularly frequent in neonatal period. Their causes are varied and their knowledge is capital for their good management. Our purpose was to describe the epidemiological, diagnostic, and common causes of new-bornhaemorrhagic syndrome in paediatric emergency medical department of the Rabat Children's Hospital. We conducted a descriptive study from December 2015 to April 2016, about new-borns admitted to medical emergencies for haemorrhagic syndrome defined by bleeding, exteriorized or not, whatever its importance, severity, causes and the associated clinical and biological disorders. Between December 2015 and April 2016, we identified 30 cases of newborn haemorrhagic syndromes on 594 hospitalizations (5.05%). The sex-ratio (M/F) was 1.5. None of them received vitamin K after birth and all were breastfed. Preterm infants accounted for 10%. The presentation of haemorrhage encountered was dominated by visceral bleeding especially digestive (80%), followed by epistaxis (10%), Haematuria (7%), and skin haemorrhage (3%). Physical examination was normal in most of cases with exception (nine babies had pallor with hypotonia, three babies suffered from hypovolemic shock, respiratory distress(10%), drowsiness, poor sucking and fever. The most common cause of bleeding disorder was haemorrhagic disease of the new-born (80%), disseminated intravascular coagulation (DIC) (10%), esophagitis (6.67%) and isolated thrombocytopenia (3.33%). At the end of our study, given the high frequency of vitamin k deficiency bleeding disease despite the prophylaxis received, a strengthening of the prevention system is necessary.
