Abstract

Introduction: Right diaphragmatic excursion is a reliable and reproducible technique used in intensive care to assess diaphragmatic function. The aim of this study was to investigate the relationship between the appearance of diaphragmatic motion and the etiological diagnosis of patients admitted to the emergency department with acute respiratory failure (ARF).

Materials: A prospective, observational, and multicenter pilot study was conducted. All adult patients admitted in the emergency department with ARF were included. The different visual patterns of diaphragmatic motion were analyzed according to the three main etiologies of ARF encountered in emergency departments.

Results: A total of 39 adult patients were included. We observed a different visual pattern in patients with pneumonia. A sum of plateau times of less than 0.2 s predicted that the main diagnosis was pneumonia, with sensitivity = 89% 95%CI [52%; 100%], specificity = 87% 95%CI [69%; 96%].

Conclusion: Our study seems to show that the shape of diaphragmatic motion in patients with ARF secondary to pneumonia is different from that in patients with exacerbation of chronic obstructive pulmonary disease or acute heart failure.

Trial registration: ClinicalTrials.gov: NCT04591509.

急性呼吸衰竭患者膈肌运动的视觉模式：前瞻性试点研究

介绍：右侧膈肌游离是重症监护中用于评估膈肌功能的一种可靠且可重复的技术。本研究旨在调查急性呼吸衰竭（ARF）急诊科入院患者的膈肌运动外观与病因诊断之间的关系：材料：开展了一项前瞻性、观察性、多中心试验研究。研究对象包括急诊科收治的所有急性呼吸衰竭成人患者。根据急诊科遇到的 ARF 的三种主要病因，分析膈肌运动的不同视觉模式：结果：共纳入 39 名成年患者。我们在肺炎患者中观察到了不同的视觉模式。高原时间总和小于 0.2 秒可预测主要诊断为肺炎，灵敏度 = 89% 95%CI [52%; 100%]，特异性 = 87% 95%CI [69%; 96%]：我们的研究似乎表明，继发于肺炎的 ARF 患者的膈肌运动形状与慢性阻塞性肺病或急性心力衰竭加重期患者的膈肌运动形状不同：试验注册：ClinicalTrials.gov：试验注册：ClinicalTrials.gov：NCT04591509。

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
