1984年维多利亚出生≥500g的婴儿60,704人,其中死产426例,新生儿死亡339例。围产死亡率为12.6‰,本文目的为了引起对妊娠36周后尸检全部有宫内缺氧的不明原因的胎死宫内的关注。出生体重≥2,500g的252例围产儿死亡中,59例(23.4%)为不明原因的胎死宫内,这是最大一组可避免的死亡,仅次于先天畸形,占围产儿死亡的第二位,通过该类病例的临床资料表明,出生体重>2,500g,围产死亡率下降,不明原因的死胎亦减少,约为1/970例妊娠。该59例中54例(91.5%)为适于胎龄儿,故以超声筛选有一定困难,通过胎
In 1984, there were 60,704 babies born in Victoria ≥ 500g, of whom 426 were stillborn and 339 were neonatal deaths. The perinatal mortality rate was 12.6 ‰. The purpose of this paper was to raise awareness of the unexplained fetal death in utero hypoxemia at postmortem 36 weeks after pregnancy. Of the 252 perinatal deaths with birth weights ≥2,500g, 59 (23.4%) were unexplained fetal deaths, the largest group of avoidable deaths, second only to congenital malformations, accounting for the number of perinatal deaths Second, through the clinical data of such cases showed that birth weight> 2,500 g, decreased perinatal mortality, unexplained stillbirth also decreased, about 1/970 cases of pregnancy. Of the 59 cases, 54 (91.5%) were suitable for gestational age children, so ultrasound screening had some difficulties.
