研究概览
简要总结
The purpose of this study is to determine the utility of point-of-care lung ultrasound (POC-LUS) in identifying the etiology of acute respiratory failure in pediatric patients admitted to the pediatric intensive care unit.
详细描述
Respiratory failure is one of the most common conditions requiring admission to the pediatric intensive care unit (PICU). As such, chest radiography has emerged as the most commonly utilized tool in the assessment of lung pathology despite evidence that it may not be the most accurate. Since the seminal article by Lichtenstein in 2008, lung ultrasound has emerged as an alternative to chest radiography in the assessment of critically ill adults. Likewise, pediatric lung ultrasound has a growing body of research to support its use in commonly encountered lung pathology including pneumonia, asthma, bronchiolitis, acute chest syndrome, pleural effusions, and pneumothorax. Despite the rapidly growing body evidence, there remains little literature to support its use the diagnosis and management of acute respiratory failure in the PICU.
The proposed study will evaluate whether point-of-care lung ultrasound is accurate in determining the etiology of acute respiratory failure on admission to the PICU.
Specific aims include:
- Aim 1: To determine the sensitivity and specificity of point-of-care lung ultrasound examination in identifying the etiology of acute pediatric respiratory failure on admission to the PICU.
- Aim 2: To determine the inter-observer reliability of point-of-care lung ultrasound examination findings in acute pediatric respiratory failure among trainee and expert sonographers.
- Aim 3: Compare point-of-care lung ultrasound with chest radiography in the rate of detection of consolidation, interstitial edema, pneumothorax, and pleural effusion.
- Aim 4: Describe the POC-LUS findings in patients admitted to the PICU with acute respiratory failure

结局指标
主要结局
Sensitivity of point-of-care lung ultrasound examination in identifying the etiology of acute pediatric respiratory failure on admission to the PICU
时间窗: up to one month
The sensitivity of the lung ultrasound in identifying the etiology of acute pediatric respiratory failure will be determined by comparison with the final criterion or "gold standard" diagnosis generated by a blinded review of the chart after discharge by a study investigator blinded to the case. The hypothesis is that the lung ultrasound performed on admission to the PICU will have a sensitivity of \> 90% in determining the etiology of acute respiratory failure in children (as determined by an independent review of the participant's medical record following hospital discharge).
