隔膜超声波 (DUS) 在客观测量儿科喘严重程度方面表现有前途. 隔膜厚化 (DT) 和厚化分数 (TF) 的米达克西拉测量与喘严重程度有很好的相关性,并显示出良好的可靠性.
科学领域:
- 儿科急救医学 儿科急救医学
- 肺部病理学 肺部病理学
- 医疗成像医学成像
背景情况:
- 喘恶化是儿童急诊室访问的主要原因.
- 评估儿童喘严重程度的客观工具是有限的.
- 隔膜超声波 (DUS) 是一种评估呼吸困难的新兴技术.
研究的目的:
- 为了研究隔膜超声波 (DUS) 参数 (隔膜外游,隔膜加厚和隔膜加厚分数) 与儿童喘严重程度之间的相关性.
- 评估DUS参数与需要呼吸辅助之间的关系.
- 为了评估儿童喘患者中DUS的评分器间可靠性.
主要方法:
- 一项前性研究招募了5至18岁的患有喘恶化症的儿童.
- 隔膜超声波 (DUS) 是由儿科急诊医学声学家进行的.
- 测量包括肋下隔膜外流 (DE) 和中间骨隔膜厚化 (DT);计算了厚化分数 (TF). 在一个子集上评估了Interrater可靠性.
主要成果:
- 米达克西拉膜加厚 (DT) 和加厚分数 (TF) 在轻度和中度喘严重程度之间显示出显著的差异 (P=0.02).
- 肋下腹膜外流 (DE) 与喘严重程度没有相关性 (P=0.43).
- 对于中轴心DT (皮尔森相关性=0.56) 观察到强烈的interrater可靠性,但对于肋下DE (皮尔森相关性=0.18) 没有.
结论:
- 隔膜超声波 (DUS) 显示出作为评估儿科喘严重程度的客观工具的潜力.
- 测量隔膜厚化 (DT) 和厚化分数 (TF) 的中视图显示了与喘严重程度和最佳interrater可靠性最强的相关性.
- 未来的研究应该集中在儿科喘中用于DT和TF的中轴心DUS方法上.
