[Ischemic necrosis of the gluteal area with sciatic nerve damage in newborn infants].

The pathogenesis of dry gluteal necrosis with the involvement of the sciatic nerve as a severe complication of neonatal resuscitation employing umbilical drug administration has been elucidated by angiographic studies. This complication was found to result from a spasm and subsequent thrombosis of the internal iliac artery induced by intraumbilical drug administration. Guidelines for the prevention of this severe complication are offered.
