A retrospective case record analysis of all perinatal and late neonatal deaths in Iceland in the periods 1976-80 and 1981-85 was done and the causes of death classified according to the extended Aberdeen classification. There was a significant (p less than 0.0001) reduction in number of deaths between the two periods with perinatal mortality rates declining from 10.6/1000 in 1976-80 to 6.8/1000 in 1981-85. In 1976-80 there were 81 (33%) antepartum, 37 (15%) intrapartum and 128 (52%) neonatal deaths compared to 61 (38%) antepartum, 13 (8%) intrapartum and 86 (54%) neonatal deaths in 1981-85. Fetal abnormality was the most common cause of death in both periods followed by the category Low birthweight in 1976-80. In 1981-85 increased morphological detection of infection in infants of very low birthweight by placental examination and autopsies lead to a shift from the category Low birthweight to Maternal Disease, the second most common cause in that period. To achieve lower perinatal mortality rates efforts should be directed towards lowering antepartum losses near term and increasing survival of very low birthweight infants.
对冰岛1976 - 1980年和1981 - 1985年期间所有围产期和晚期新生儿死亡病例记录进行了回顾性分析，并根据扩展的阿伯丁分类法对死亡原因进行了分类。两个时期之间的死亡人数有显著减少（p小于0.0001），围产期死亡率从1976 - 1980年的10.6‰降至1981 - 1985年的6.8‰。1976 - 1980年有81例（33%）产前死亡、37例（15%）产时死亡和128例（52%）新生儿死亡，而1981 - 1985年分别为61例（38%）产前死亡、13例（8%）产时死亡和86例（54%）新生儿死亡。胎儿异常是两个时期最常见的死亡原因，1976 - 1980年其次是低出生体重类别。1981 - 1985年，通过胎盘检查和尸检对极低出生体重婴儿感染的形态学检测增加，导致死亡原因从低出生体重类别转变为母体疾病，母体疾病是该时期第二常见的原因。为了实现更低的围产期死亡率，应努力降低接近足月时的产前死亡，并提高极低出生体重婴儿的存活率。
