Fatal foreign body ingestion in childhood usually results in sudden and unexpected death from acute upper airway occlusion. The most common age range for such episodes is one to three years. However, a variety of different mechanisms of death due to ingested foreign bodies may occur in children, including hemorrhage, acute cardiac tamponade, arrhythmia, centrally mediated respiratory arrest and sepsis. Sudden death may follow a protracted asymptomatic period and may also be due to foreign bodies impacted in the esophagus. A review of cases has been undertaken (N = 10; age = three and one-half months to seven years; M:F = 9:1), which demonstrates the variety of lethal processes that may occur, the range of materials involved and the different anatomical sites where problems can result.
儿童期致命性异物吞食通常会因急性上呼吸道阻塞导致突然且意外的死亡。此类事件最常见的年龄范围是1至3岁。然而，儿童因吞食异物导致死亡的机制多种多样，包括出血、急性心脏压塞、心律失常、中枢介导的呼吸骤停和败血症。猝死可能发生在一段漫长的无症状期之后，也可能是由于异物嵌顿在食管所致。已对病例进行了回顾（N = 10；年龄 = 三个半月至7岁；男:女 = 9:1），这显示了可能发生的各种致死过程、所涉及物质的范围以及可能出现问题的不同解剖部位。
