A great role in the pathogenesis of traumas in newborns is assigned to hypoxia and hypoxic hemorrhages, and also to mechanical impacts during deliveries. This is associated with objective difficulties in diagnosis of traumas of organs of the abdominal cavity and of the retroperitoneal space in newborns. Aim. To present and analyze clinical cases of trauma of parenchymal organs of the abdominal cavity and of the retroperitoneal space in newborns. In clinics of childrens surgery seven children with pathology of adrenals, three with trauma of the liver and one with rupture of spleen have been observed within the recent 10 years. No damages to the stomach, pancreas, duodenum, small and large intestine, kidneys and urinary bladder were recorded. In the article clinical cases of trauma of adrenals, liver and spleen are presented. Conclusion. Damages to parenchymal organs of the abdominal cavity and of the retroperitoneal space in newborns are very rare. More commonly adrenals are affected, less commonly liver and spleen. The diagnosis of a parenchymal organ in newborns is a reason for immediate transferal of the child to a surgical hospital.
