After severe burn injury, pediatric patients often succumb to complications of respiratory failure. Surfactant has been used to improve pulmonary gas exchange for severe respiratory distress in other pediatric populations but has not been studied in pediatric burn-injured patients. Here, the authors report a case series of seven severely burned pediatric patients who received surfactant for acute respiratory distress and severe hypoxemia. Seven cases were reviewed of pediatric patients who received surfactant for severe acute respiratory distress. Data analyzed included age, TBSA burned, height, weight, mechanism of injury, total intensive care unit days, hospital days, and ventilator days. Modes of ventilation, peak inspiratory pressure, oxygen requirement, arterial blood gas analysis, blood pressure, and heart rate were analyzed before and the day following surfactant therapy. Four patients had reduced oxygen requirements following surfactant administration (FiO(2): 0.66 ± 0.23-0.48 ± 0.025). Three patients showed no reduction in oxygen requirements (FiO(2): 0.95 ± 0.09-0.90 ± 0.0). The remaining four patients who had reduced oxygen requirements received surfactant earlier following their injury (4.8 ± 0.9 days postinjury vs 17.7 ± 8 days postinjury) and had less derangement in oxygenation before surfactant dosing (PaO(2):FiO(2) ratio: 105.2 ± 26.4 vs 64.5 ± 5.2). Surfactant therapy may offer a therapeutic option during acute respiratory distress for severely burned pediatric patients. Surfactant may be useful early in the course of severe hypoxemia and acute respiratory distress but may not be effective as a salvage modality.
严重烧伤后,儿科患者常死于呼吸衰竭并发症。表面活性剂已被用于改善其他儿科人群严重呼吸窘迫时的肺气体交换,但尚未在儿科烧伤患者中进行研究。在此,作者报告了一组7例严重烧伤儿科患者的病例系列,这些患者接受了表面活性剂治疗急性呼吸窘迫和严重低氧血症。回顾了7例接受表面活性剂治疗严重急性呼吸窘迫的儿科患者的病例。分析的数据包括年龄、烧伤总面积、身高、体重、损伤机制、重症监护病房总天数、住院天数和呼吸机使用天数。在表面活性剂治疗前和治疗后一天分析通气模式、吸气峰压、氧需求、动脉血气分析、血压和心率。4例患者在给予表面活性剂后氧需求降低(吸入氧分数:0.66±0.23至0.48±0.025)。3例患者氧需求未降低(吸入氧分数:0.95±0.09至0.90±0.0)。其余4例氧需求降低的患者在受伤后更早接受表面活性剂治疗(受伤后4.8±0.9天与受伤后17.7±8天),且在给予表面活性剂前氧合紊乱程度较轻(动脉血氧分压与吸入氧分数比值:105.2±26.4与64.5±5.2)。表面活性剂治疗可能为严重烧伤儿科患者急性呼吸窘迫期间提供一种治疗选择。表面活性剂在严重低氧血症和急性呼吸窘迫病程早期可能有用,但作为挽救措施可能无效。
