摘要 患儿女,第1胎第1产,胎龄39周+6,出生体重3180 g。孕母正规产前检查。患儿出生时羊水Ⅱ度胎粪污染,无窒息。生后8 h,患儿出现进行性加重的呼吸困难,胸部X射线提示肺部渗出影,右侧较左侧显著,外院先后给予经鼻正压通气及气管插管机械通气等治疗,进行血培养等检查,加用抗生素抗感染治疗,病情无好转。于2015年8月10日,生后17 h,在机械通气下由复旦大学附属儿科医院新生儿科转运团队转运至该院新生儿重症监护病房。患儿入院后在常频机械通气的情况下,呼吸困难明显,C-反应蛋白(C-reactive protein,CRP)22 mg/L,血气分析示pH 7.24,氧分压(partial pressure of oxygen,PO2)35.5 mmHg(1 mmHg=0.133 kPa),二氧化碳分压(partial pressure of carbon dioxide,PCO2)40.8 mmHg,碱剩余(base excess,BE)-9.0 mmol/L。入院诊断:新生儿呼吸窘迫综合征,新生儿败血症可疑,肺动脉高压。给予高频机械通气,肺泡表面活性物质治疗,并使用血管活性药物(米力农、多巴胺和肾上腺素)改善循环;一氧化氮吸入降低肺动脉高压。生后21 h,患儿病情进一步恶化,氧合指数为45。经过评估,患儿生后23 h开始动脉-静脉模式的体外膜肺氧合(extracorporeal membrane oxygenation,ECMO)。生后24 h血培养结果回报B族链球菌(group BStreptococcus,GBS)阳性。患儿入院后存在CRP等炎症指标增高,脏器功能障碍(顽固性低血压和低氧血症),组织低灌注(乳酸增高,毛细血管再充盈时间延长),诊断为败血症合并呼吸循环衰竭。
