“…US can show (1) alignment of the immobile vocal cords compared to the midline to assess any possible superior or inferior misalignment, and (2) lateromedial and supero-inferior movements during phonation to appreciate a possible discrepancy in the mobility of the vocal cords secondary to an imminent or known paresis [11]. US has also been used for detecting neoplastic masses or vocal cord inflammation [11][12][13]. Assessment of correct endotracheal tube placement US can show the presence of the endotracheal tube in the trachea [14] either directly or after increasing the echogenicity (by gently moving a stylet inside it or by inflation of the tube cuff using fluid or air bubbles) [15].…”

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...

Context:The scope of ultrasound is emerging in medical science, particularly outside traditional areas of radiology practice.Aims:We designed this study to evaluate feasibility of bedside sonography as a tool for airway assessment and to describe sonographic anatomy of airway.Settings and Design:A prospective, clinical study.Materials and Methods:We included 100 adult, healthy volunteers of either sex to undergo airway imaging systemically starting from floor of the mouth to the sternal notch in anterior aspect of neck by sonography.Results:We could visualize mandible and hyoid bone as a bright hyperechoic structure with hypoechoic acoustic shadow underneath. Epiglottis, thyroid cartilage, cricoid cartilage, and tracheal rings appeared hypoechoic. Vocal cords were visualized through thyroid cartilage. Interface between air and mucosa lining the airway produced a bright hyperechoic linear appearance. Artifacts created by intraluminal air prevented visualization of posterior pharynx, posterior commissure, and posterior wall of trachea.Conclusions:Ultrasound is safe, quick, noninvasive, repeatable, and bedside tool to assess the airway and can provide real-time dynamic images relevant for several aspects of airway management.

“…Preliminary results of bedside ultrasonography show that it is a safe and effective tool to diagnose acute epiglottitis. In two recent studies, Hung et al [43] visualized the "P sign" in a longitudinal view through the thyrohyoid membrane. Ko et al [44] found a significant difference in the anteroposterior diameter of the epiglottis in acute epiglottitis patients.…”

Ultrasound is a safe, portable, relatively inexpensive, and easily accessible imaging modality, making it a useful diagnostic and monitoring tool in medicine. Anesthesiologists encounter a variety of emergent situations and may benefit from the application of such a rapid and accurate diagnostic tool in their routine practice. This paper reviews current and potential applications of ultrasound in anesthesiology in order to encourage anesthesiologists to learn and use this useful tool as an adjunct to physical examination. Ultrasound-guided peripheral nerve blockade and vascular access represent the most popular ultrasound applications in anesthesiology. Ultrasound has recently started to substitute for CT scans and fluoroscopy in many pain treatment procedures. Although the application of airway ultrasound is still limited, it has a promising future. Lung ultrasound is a well-established field in point-of-care medicine, and it could have a great impact if utilized in our ORs, as it may help in rapid and accurate diagnosis in many emergent situations. Optic nerve sheath diameter (ONSD) measurement and transcranial color coded duplex (TCCD) are relatively new neuroimaging modalities, which assess intracranial pressure and cerebral blood flow. Gastric ultrasound can be used for assessment of gastric content and diagnosis of full stomach. Focused transthoracic (TTE) and transesophageal (TEE) echocardiography facilitate the assessment of left and right ventricular function, cardiac valve abnormalities, and volume status as well as guiding cardiac resuscitation. Thus, there are multiple potential areas where ultrasound can play a significant role in guiding otherwise blind and invasive interventions, diagnosing critical conditions, and assessing for possible anatomic variations that may lead to plan modification. We suggest that ultrasound training should be part of any anesthesiology training program curriculum.
