Abstract：
UNASSIGNED: To investigate the aetiologies of sudden unexpected death from natural causes in children aged 1-18 years by retrospective examination of autopsy records from a single centre.
UNASSIGNED: The post-mortem findings from 548 children (1996-2015) were examined. Details were entered into an established research database and categorized according to >400 pre-defined criteria.
UNASSIGNED: There were 265 previously apparently healthy children and 283 with pre-existing, potentially life-limiting, conditions. There were more males than females (M:F 1.4:1), and deaths were more frequent in the winter. Infection was commonest accounting for 43% of all deaths. Non-infectious diseases were identified as cause of death in 28%, and 29% of all deaths were unexplained. There was no significant difference in the proportions of deaths in each category between the previously healthy children and those with pre-existing conditions.
UNASSIGNED: Sudden unexpected death is a rare presentation of death in childhood and those with pre-existing conditions may be more at risk. Standardisation of the post-mortem procedure in such cases may result in more ancillary investigations performed as routine and may reduce the number of cases that are \'unexplained\'.

摘要：
UNASSIGNED：通过回顾性检查单个中心的尸检记录，调查1-18岁儿童自然原因猝死的病因。
UNASSIGNED：检查了548名儿童（1996-2015年）的验尸结果。将详细信息输入已建立的研究数据库，并根据>400预定义的标准进行分类。
UNASISIGNED：有265名以前看起来健康的儿童和283名预先存在的儿童，潜在的生命限制，条件。男性多于女性（M：F1.4：1），冬季死亡更为频繁。感染是最常见的，占所有死亡的43％。非传染性疾病被确定为死亡原因的28%，29%的死亡原因不明。先前健康的儿童和先前存在疾病的儿童之间，每个类别的死亡比例没有显着差异。
UNASSIGNED：突然意外死亡是儿童时期罕见的死亡表现，那些有既往疾病的人可能更有风险。在这种情况下，验尸程序的标准化可能会导致例行进行更多的辅助调查，并可能减少“无法解释”的案件数量。
