Acute respiratory distress syndrome (ARDS) is a clinical condition characterized by acute diffuse inflammatory lung injury and severe hypoxemia. In 2017, the Montreux Consensus defined diagnostic criteria for ARDS in the neonatal period. The management of ARDS includes strict adherence to lung-protective ventilation strategies and therapeutic agents to improve gas exchange. We report two similar cases of premature infants with gestational ages of 23 and 24 weeks diagnosed with neonatal ARDS according to the Montreux definition. These patients developed acute worsening of oxygenation on the 30th and 28th day of life, respectively, while they were ventilated on volume-guarantee assist/control mode. Chest X-rays revealed bilateral diffuse opacity, there were no cardiogenic origins for pulmonary edema, and their oxygenation indexes were >8. Both cases fulfilled the neonatal ARDS criteria and the patients' clinical conditions were associated with late onset neonatal sepsis. After lung recruitment maneuver, the infants began HFO volume-guarantee ventilation and received surfactant treatment. Since they showed a poor short-term response, intratracheal surfactant of 100 mg/kg plus budesonide of 0.25 mg/kg were administered and their oxygenation indexes were reduced stepwise. Both patients survived and were discharged home with spontaneous breathing of room air. Neonatal ARDS is generally an underdiagnosed condition associated with sepsis, pneumonia, and meconium aspiration. Impaired surfactant activity and reduced lung compliance play important roles in its pathophysiology. To our knowledge, this is the first case report indicating the possible therapeutic role of budesonide plus surfactant in ARDS treatment. Since ARDS is an entity not recognized in newborns, we want to emphasize neonatal ARDS diagnosis and underline that the combination of budesonide and surfactant may be a novel therapeutic option in the treatment of ARDS.
急性呼吸窘迫综合征(ARDS)是一种以急性弥漫性炎症性肺损伤和严重低氧血症为特征的临床病症。2017年,蒙特勒共识确定了新生儿期ARDS的诊断标准。ARDS的治疗包括严格遵循肺保护性通气策略以及使用改善气体交换的治疗药物。我们报告了两例胎龄分别为23周和24周的早产儿,根据蒙特勒定义诊断为新生儿ARDS。这两名患者分别在出生后第30天和第28天,在容量保证辅助/控制模式通气时出现氧合急性恶化。胸部X线显示双侧弥漫性模糊影,肺水肿无心源性病因,且其氧合指数>8。两例均符合新生儿ARDS标准,且患者的临床状况与晚发性新生儿败血症相关。在进行肺复张手法后,婴儿开始高频振荡通气并接受表面活性剂治疗。由于他们显示出短期反应不佳,给予100mg/kg气管内表面活性剂加0.25mg/kg布地奈德,其氧合指数逐步降低。两名患者均存活并在空气中自主呼吸的情况下出院回家。新生儿ARDS通常是一种诊断不足的病症,与败血症、肺炎和胎粪吸入有关。表面活性剂活性受损和肺顺应性降低在其病理生理学中起重要作用。据我们所知,这是首例表明布地奈德加表面活性剂在ARDS治疗中可能具有治疗作用的病例报告。由于ARDS在新生儿中并非公认的疾病实体,我们想强调新生儿ARDS的诊断,并强调布地奈德和表面活性剂的联合使用可能是治疗ARDS的一种新的治疗选择。
