摘要：

松弛婴儿系指出生或婴儿早期即出现肌张力低下的一类婴儿，婴儿松弛综合征临床表现为骨骼肌肌张力低下。肌张力低下由多种原因导致，原发性肌张力低下包括中枢性和周围性肌张力低下或二者兼有导致的混合性肌张力低下。部分婴儿松弛综合征是遗传性疾病或罕见病。本文通过文献梳理，对婴儿松弛综合征的病因、临床表现、辅助检查、诊断与鉴别诊断、治疗、多学科管理进行综述。

Abstract:

The term "floppy infant" is used for describing children presenting with muscle hypotonia at or shortly after birth. The clinical manifestation of floppy infants is skeletal muscle hypotonia, which may be caused by a lot of reasons. Primary hypotonia includes central hypotonia, peripheral hypotonia, or mixed hypotonia of both. Partial floppy infant syndrome is hereditary and rare. This article reviews the literatures, mostly retrospective studies, on etiology, clinical manifestations, auxiliary examinations, differential diagnosis, treatment and multidisciplinary management of floppy infant syndrome.
