The use of ultrasound to visualize the diaphragm is well established. Over the last 15 years, certain indices of diaphragm function, namely diaphragm thickness, thickening fraction and excursion have been established for mechanically ventilated patients to track changes in diaphragm size and function over time, to assess and diagnose diaphragmatic dysfunction, and to evaluate if these indices can predict successful liberation from mechanical ventilation. In the last 2 years, three meta-analyses and a systematic review have assessed the usability of diaphragmatic ultrasound to predict successful weaning. Since then, further data have been published on the topic.
The aim of this narrative review is to briefly describe the common methods of diaphragmatic function assessment using ultrasound techniques, before summarizing the major points raised by the recent reviews. A narrative summary of the most recent data will be presented, before concluding with a brief discussion of future research directions in this field.
使用超声可视化膈肌已得到充分证实。在过去15年里，已为机械通气患者确立了某些膈肌功能指标，即膈肌厚度、增厚分数和偏移，以追踪膈肌大小和功能随时间的变化，评估和诊断膈肌功能障碍，并评估这些指标是否能够预测机械通气的成功撤机。在过去两年中，三项荟萃分析和一项系统评价评估了膈肌超声预测成功撤机的可用性。自那时以来，关于该主题又发表了更多数据。
本叙述性综述的目的是在总结近期综述提出的要点之前，简要描述使用超声技术评估膈肌功能的常用方法。将呈现最新数据的叙述性总结，最后简要讨论该领域未来的研究方向。
