“…It is not the first time that a precision study is carried out with this purpose. Available data, however, result inconclusive, since technical issues were raised [12] and conflicting data currently exist [10]. We found the fifth percentile of diaphragm motion to be 17.7 and 13.5 mm at QB, and 62.6 and 49.6 mm at DB for the male and female population, respectively.…”

Background: Assessing diaphragm mobility is important to detect malfunctions or impending exhaustion and to evaluate the effects of many chest and abdominal conditions on respiratory mechanics. Amongst several imaging methods, ultrasonography represents the only noninvasive, nonionizing imaging technique widely available for the direct assessment of diaphragm excursion. Objectives: the aim of this study is to prospectively assess the supine diaphragmatic motion amplitude, intra- and inter-observer agreement, and anthropometric correlates of diaphragm motion variability, measured through M-mode ultrasonography, in a sample of healthy volunteers. Methods: One-hundred healthy volunteers were considered eligible for the study. Instead of B-mode imaging, the M-mode technique was used to achieve a more accurate measurement of diaphragm motion. To assess intra-observer variability, 3 consecutive measurements (M-mode and B-mode) of the right dome motion were obtained at every session. To test for inter-rater reliability, the subjects were asked to provide 2 more diaphragm motion measurements every week, each performed by 2 experienced operators, and 42 subjects accepted. Results: Diaphragmatic motion was positively correlated with height and weight both at quiet (Spearman’s coefficient = 0.514, p < 0.001 and 0.314, p = 0.038) and deep breathing (Spearman’s coefficient = 0.342, p = 0.001 and 0.225, p = 0.024, respectively) and negatively correlated with age, but only during deep breathing (Spearman’s coefficient = –0.272, p = 0.006). Intra-observer agreement degree on all 3 measurements was excellent during both quiet and deep breathing, with a Cronbach’s alpha of 0.793 and 0.901, respectively, and an intra-class coefficient of 0.797 and 0.900, respectively. Similarly, the degree of inter-observer agreement achieved a Cronbach’s alpha of 0.638 and 0.776, and an inter-class coefficient of 0.632 and 0.778, respectively. Deep breathing was associated with sex only in linear multivariable models (B = –10.14; 95% confidence interval [CI] –17.86, –2.41; p = 0.011), while quiet breathing resulted to be affected by height only (B = 30.05; 95% CI 0.79–59.31; p = 0.044). Conclusions: Diaphragm excursion measurements using the M-mode technique were accurate and could be reproduced also when obtained in recumbent patients. After adjustments, the main predictors of diaphragmatic motion were sex and height, which should be considered to design a specifically tailored study and to develop normality reference equations.

“…The diaphragm and lung movements, which are qualitative and quantitative signs that the lungs are properly ventilated, can be directly and easily documented by US [16]. If the movements of the diaphragm are symmetrical on both sides, and intercostal US scan shows the presence of bilateral lung sliding synchronous with the ventilation, it can be inferred that the endotracheal tube is correctly placed in the trachea [17,18]. In cases of esophageal intubation, assisted ventilation is not followed by lung expansion, but the diaphragm movements may follow the patient's spontaneous breathing if it has not been pharmacologically suppressed.…”

Objectives The aim of this review article is to present the current views and visions of the role of ultrasound (US) in the management of patients with multiple trauma. The article is divided into two parts. Part 1 (US findings and techniques) will mainly deal with the technical aspects of US imaging in trauma patients and is written also for educational purposes. Part 2 (pathophysiology and US imaging in trauma patients) will deal with integration of US in the clinical and pathophysiological management of multiple trauma patients. Methods A non-systematic review of the literature through PubMed search (restricted to the last 10 years) of original articles and review articles. Results 80 publications were selected for Part 1. Of these 80 articles, the author selected 50 according to personal criteria on the basis of their innovative or original contents (48 original articles and 2 literature review articles); 19 articles were furthermore extracted from the references of the selected publications. The information extracted from these 69 publications was organized into sections dealing with different fields of applications of US imaging in multiple trauma patients. Conclusions US imaging in trauma has evolved from the initial use, i.e., early diagnosis of peritoneal effusion (focused abdominal sonography for trauma), to a wider use known as resuscitative ultrasonography, and is today considered as an extension of physical examination to implement a more effective approach to clinical problems and increase the timeliness and safety of interventions. Keywords Trauma Á Ultrasound Á Ultrasound findings Á Ultrasound techniqueRiassunto Obiettivi L'obiettivo di questa ricerca è di presentare la visione e le opinioni correnti sul ruolo dell'ecografia nella gestione del paziente con politrauma. L'articolo è diviso in due parti: nella prima ('Semeiotica ecografica e tecnica di esecuzione dell'esame') verrà data attenzione agli aspetti prevalentemente tecnici dell'ecografia nel trauma, con intento anche didattico; nella seconda (Fisiopatologia e ecografia clinica del trauma) sarà esplorato il tema dell'integrazione dell'ecografia con la clinica e la fisiopatologia nella gestione del politraumatizzato. Metodi Revisione non sistematica della letteratura. Ricerca su PubMed (restrizione agli ultimi 10 anni) di articoli originali e revisioni. Risultati Per la Parte prima sono stati selezionati 80 articoli, tra i quali sono stati scelti con criteri personali quelli ritenuti innovativi o originali nei contenuti (48 articoli originali, 2 revisioni di letteratura). 19 articoli sono stati estratti dalla bibliografia delle pubblicazioni prescelte. I contenuti estratti dai 69 articoli sono stati organizzati in paragrafi intitolati ai singoli ambiti di applicazione dell'ecografia nel politrauma. Conclusioni L'ecografia del trauma è evoluta dalla iniziale applicazione nella diagnosi precoce del versamento peritoneale (Focused Abdominal Sonography for Trauma o FAST) all'accezione più ampia di Resuscitative Ultrasonography (RUS) e v...

“…Besides visualization of the endotracheal tube within the trachea, other studies have confirmed with ultrasound (US) that successful intubation with an ETT had occurred using either the sliding lung sign of visceral-parietal pleural movement [2,3,4] or by diaphragmatic motion along the lateral chest wall [5,6]. …”

Background: The placement of the endotracheal tube (ETT) in neonates is a challenging procedure that currently requires timely confirmation of tip placement by radiographic imaging. Objective: We sought to determine if bedside ultrasound (US) could demonstrate ETT tip location in preterm and term newborns and offer a quick alternative method of ETT positioning. Methods: We conducted a prospective pilot study of 30 newborns admitted to the UC San Diego Medical Center who had their ETT placement confirmed by chest radiographs. After a radiograph, each infant had a US exam with a 13-MHz linear transducer on a portable US machine. To assist localization, gentle longitudinal movement of the ETT of less than 0.5 cm was performed. Measurements from the tip of the ETT tip to the carina were made on chest radiograph and midsagittal US images. Results: Study infants had a mean gestational age of 30.2 ± 4.9 (SD) weeks and mean birth weight of 1,595.2 ± 862 g. US images were taken a mean 2.9 ± 2.2 h after radiographs. Data from 2 infants were excluded for poor radiograph image quality and extreme outlier values. The ETT was visualized by US in all newborns examined. We observed a good correlation between ETT tip-to-carina distance on US and radiograph (r² = 0.68) with minimal bias. Each study took less than 5 min to obtain without any clinical deterioration. Conclusions: Bedside US can visualize the anatomic position of the ETT position in preterm and term infants but further validation is required before routine clinical implementation.

Secondary confirmation of endotracheal tube position by ultrasound image

Abstract: Ultrasound imaging of diaphragm motion is a useful, quick, noninvasive, portable, and direct anatomic method for assessment of ET tube position. We think it should be considered the method of choice for the secondary confirmation of the ET tube position.
