新生儿侵袭性真菌感染67例临床分析

目的 探讨新生儿侵袭性真菌感染的临床特点.方法 选取2009年1月至2010年12月收治的67例侵袭性真菌感染新生儿病例,分析其病原、高危因素、临床特点、实验室检查及转归情况.结果 67例患儿均为念珠菌属感染,以白色念珠菌感染最为常见,占47.7%,其次为光滑假丝酵母菌,占43.3%;早产儿占所有病例的91.0%,其中50%以上的早产儿胎龄≤ 32周,9例存在先天性消化道畸形,11例合并有巨细胞病毒感染;25例患儿真菌感染前经外周中心静脉插管(PICC)置管时间≥ 14 d,16例气管插管机械通气治疗时间＞ 7 d;35例(52.2%)患儿白细胞计数＜ 10 × 109 /L,46例(68.7%)患儿有血小板下降,其中33例持续≥ 7 d;24例患儿伴有器官受累,包括中枢神经系统、眼及关节;47例(70.1%)经抗真菌治疗后病情好转或治愈,15例(22.4%)患儿死亡.结论 新生儿侵袭性真菌感染的病原主要为念珠菌属,尤以白色念珠菌及光滑假丝酵母菌为多见.中枢神经系统、眼及关节为常见受累器官.侵袭性真菌感染的发生、严重程度及转归与患儿的机体状态、原发病及并发症密切相关.
