目的 报道1例新生儿单纯疱疹病毒中枢神经系统感染病例,并通过文献回顾和复习,提高临床上对此类少见病的认识,减少该病的误诊、漏诊。方法 回顾性分析1例新生儿单纯疱疹病毒中枢神经系统感染患儿的发病、诊断和治疗过程,结合以往的文献报道,总结该病的临床表现和诊治要点。结果 回顾文献显示:新生儿单纯疱疹病毒中枢神经系统感染非常少见。病死率高,存活者大多存在神经系统不良结局。本例为14天大新生儿,因发热入院,原因未明,入院即予阿昔洛韦抗病毒治疗取得良好疗效,随访至今(3月大),未见神经系统异常表现。提示及早有效的抗病毒治疗是影响预后的关键因素。结论 新生儿单纯疱疹病毒中枢神经系统感染临床无特异性表现,此病少见。尽早、足程的抗病毒治疗,可明显改善患儿的预后。对于不明原因发热的新生儿(特别是社区获得者),早期经验性予以阿昔洛韦抗病毒治疗,利大于弊。

Objective To report a case of herpes simplex virus central nervous system infection in a neonate and to review literatures about this disease, and to improve clinical understanding of this rare disease and reduce misdiagnosis and missed diagnosis. Methods The clinical manifestation,diagnosis and treatment of the patient with herpes simplex virus central nervous system infection were analyzed.The epidemiology,clinical manifestation and key points of diagnosis were summarized from literature review. Results Literature review showed that: neonatal herpes simplex virus central nervous system infection is very rare. The mortality rate is high, and most of the survivors have adverse neurological outcomes. This case is a fourteen days newborn who was admitted to the hospital due to fever for unknown reasons. He was given acyclovir antiviral therapy immediately after admission and achieved good results. Follow-up of 3 months showed no neurological abnormalities. It suggested that early and effective antiviral therapy is a key factor affecting the prognosis. Conclusion Neonatal herpes simplex virus central nervous system infection has no specific clinical manifestations, and this disease is rare. Early, full-course of antiviral therapy can greatly improve the prognosis of children. For newborns with unexplained fever (especially those obtained in the community), early empirical antiviral treatment with acyclovir is more beneficial than harmful.

目的 研究低Apgar评分新生儿外周动脉(非脐动脉,以下同)血pH对新生儿窒息诊断的作用。方法 选取本院出生Apgar评分1min≤7分活产婴儿158例,复苏后1 h内,平均(33±3.9)min,抽取外周动脉血气,分析其pH与Apgar评分及多器官损害关系,以探讨它们之间作为窒息诊断的互补性。结果 复苏后的外周动脉血pH值比脐动脉血pH值高,动脉血pH与Apgar 评分呈正相关。1min Apgar评分4～7分组中pH＞7.25者占67%(109/158),且几乎在5min时Apgar评分转至8分以上,提示可能没酸中毒或窒息。动脉血pH在7.25以下或1min Apgar评分0～3分者发生多器官损害率较高,而4～7分者且pH＞7.25时多器官损害率较低。与目前窒息的诊断标准对比,本组符合率降低,可能与采用复苏后的外周动脉而非脐动脉血pH有关。结论 外周动脉血pH一定程度上可反映窒息情况,低Apgar评分不等同窒息,动脉血pH及多器官损害是判断低Apgar评分新生儿是否窒息的重要互补因素,采用复苏后才抽取的外周动脉血pH判断窒息时,如果仍以pH＜7.20为标准,可能会造成漏诊。
