新生児硬膜外出血—2症例と文献的考察

Epidural Hemorrhage in the Newborn: Report of Two Cases

Ⅰ．はじめに

　頭蓋内出血は周産期死亡の重要な原因の1つであるがasphyxia，atelectasisについで二義的と考えられる傾向にあった．

　最近，新生児の呼吸管理をはじめとする養護が改善され，またエコーグラム，右逆行性腕動脈撮影，CT scan等の検査が積極的に行なわれるようになり血腫の部位的診断も正確となって手術を行う機会が多くなった．

We have experienced 2 newborn infants with epidural hemorrhage, one of whom was operated with success.

Case 1 was a newborn male who was delivered after 37 weeks gestation by the application of obstetrical forceps. Resuscitation, such as artificial respiration and oxygen inhalation, were administered to the patient who had been asphyxiated for 25 minutes after birth. The latent period lasted 6 hours, during which time the patient did well. Then the baby's cry began to weaken. Twenty-four hours after birth, grunttng, cyanosis and convulsion occurred. He showed swellings of the scalp in the bitemporal areas. Reflexes were hyperactive.
