婴儿猝死综合征(SIDS)由于其病因不清楚,已成为人们日益关注的问题。该病多发生在出生后一月至一岁的婴幼儿,且以三月龄发病率最高。约有2/3患儿于冬季的午后至夜间突然死亡。并常呈俯卧位。多数婴儿可有轻度的非细菌性上呼吸道感染,其中有80%在尸体解剖中可发现气管内瘀点,以上均提示与阻塞性睡眠呼吸暂停有关。由于喉是上呼吸道最狭的部位,组织学显示该部位有大量腺体组织。在对100例婴儿喉部组织学检查后,出生已3月的婴儿喉部的声门部,声门下部和气管上力 Sudden Infant Death Syndrome (SIDS) has become a growing concern because of its unclear etiology. The disease occurs mostly in infants and young children between January and January of life, and has the highest incidence at three months of age.
