Abstract
Shock in the critically ill patient is common and associated with poor outcomes. Categories include distributive, hypovolemic, obstructive, and cardiogenic, of which distributive (and usually septic distributive) shock is by far the most common. Clinical history, physical examination, and hemodynamic assessments & monitoring help differentiate these states. Specific management necessitates interventions to correct the triggering etiology as well as ongoing resuscitation to maintain physiologic milieu. One shock state may convert to another and may have an undifferentiated presentation; therefore, continual re-assessment is essential. This review provides guidance for intensivists for management of all shock states based on available scientific evidence.

Abstract
Purpose The aims of this study were to prospectively assess the diagnostic accuracy of a bespoke multiorgan point-of-care ultrasound approach for suspected pulmonary embolism and evaluate if this model allows reduced referral to further radiation diagnostics while maintaining safety standards. Materials and Methods Patients with suspected pulmonary embolism referred for CT pulmonary angiography or ventilation/perfusion scintigraphy were included as a convenience sample. All patients were subject to blinded ultrasound investigation with cardiac, lung, and deep venous ultrasound. The sensitivity and specificity of applied ultrasound signs and the hypothetical reduction in the need for further diagnostic workup were calculated. Results 75 patients were prospectively enrolled. The Wells score was below 2 in 48 patients, between 2 and 6 in 24 patients, and above 6 in 3 patients. The prevalence of pulmonary embolism was 28%. The most notable ultrasound signs were presence of a deep venous thrombus, at least two hypoechoic pleural-based lesions, the D-sign, the 60/60-sign, and a visible right ventricular thrombus which all had a specificity of 100%. Additionally, a multiorgan ultrasound investigation with no findings compatible with pulmonary embolism yielded a sensitivity of 95.2% (95%CI: 76.2-99.9). CT or scintigraphy could be safely avoided in 70% of cases (95%CI: 63.0-83.1%). Conclusion The findings of our study suggest that implementation of a multiorgan ultrasound assessment in patients with suspected pulmonary embolism may safely reduce the need for CT or scintigraphy by confirming or dismissing the suspicion.

Abstract
Pulmonary hypertension (PHT) is an emerging issue. The prognosis in PHT is usually poor, independently from the etiology, with progressive right ventricle failure. Despite right Heart Catheterism is the gold standard for diagnosis of PHT, echocardiography provides important information about prognosis and is helpful in both follow-up and first evaluation of PHT patients, showing a good correlation with invasively measured parameters by right heart catheterization. However, it is important to understand the limits of this method, particularly in some settings, where transthoracic echocardiography has shown a lack of accuracy. In this case report we documented a case of rapid onset (3 months) idiopathic PHT and we provided a critical analysis of echocardiographic role in PHT.

Abstract
McConnell’s sign may be an early sign of acute RV strain in amniotic fluid embolus. TTE could be considered to facilitate timely diagnosis of amniotic fluid embolus. The presence of RV dysfunction on TTE may help guide hemodynamic therapies.

Abstract
The POCUS-CA (Point-of-care ultrasound in cardiac arrest) is a diagnostic tool in the Intensive Care Unit and Emergency Department setting. The literature indicates that in the patient in a cardiorespiratory arrest it can provide information of the etiology of the arrest in patients with non-defibrillable rhythms, assess the quality of compressions during cardiopulmonary resuscitation (CPR), and define prognosis of survival according to specific findings and, thus, assist the clinician in decision-making during resuscitation. This narrative review of the literature aims to expose the usefulness of ultrasound in the setting of cardiorespiratory arrest as a tool that allows making a rapid diagnosis and making decisions about reversible causes of this entity. More studies are needed to support the evidence to make ultrasound part of the resuscitation algorithms. Teamwork during cardiopulmonary resuscitation and the inclusion of ultrasound in a multidisciplinary approach is important to achieve a favorable clinical outcome.

Clinical Method Applied to Focused Ultrasound: The Case of Wells' Score and Echocardiography in the Emergency Department: A Systematic Review and a Meta-Analysis. MEDICINA (KAUNAS, LITHUANIA) 2021; 57:766.

Abstract
Background and Objectives: bedside cardiac ultrasound is a widely adopted method in Emergency Departments (ED) for extending physical examination and refining clinical diagnosis. However, in the setting of hemodynamically-stable pulmonary embolism, the diagnostic role of echocardiography is still the subject of debate. In light of its high specificity and low sensitivity, some authors suggest that echocardiographic signs of right ventricle overload could be used to rule-in pulmonary embolism. In this study, we aimed to clarify the diagnostic role of echocardiographic signs of right ventricle overload in the setting of hemodynamically-stable pulmonary embolism in the ED. Materials and Methods: we performed a systematic review of literature in PubMed, Web of Science and Cochrane databases, considering the echocardiographic signs for the diagnosis of pulmonary embolism in the ED. Studies considering unstable or shocked patients were excluded. Papers enrolling hemodynamically stable subjects were selected. We performed a diagnostic test accuracy meta-analysis for each sign, and then performed a critical evaluation according to pretest probability, assessed with Wells' score for pulmonary embolism. Results: 10 studies were finally included. We observed a good specificity and a low sensitivity of each echocardiographic sign of right ventricle overload. However, once stratified by the Wells' score, the post-test probability only increased among high-risk patients. Conclusions: signs of echocardiographic right ventricle overload should not be used to modify the clinical behavior in low- and intermediate- risk patients according to Wells' score classification. Among high-risk patients, however, echocardiographic signs could help a physician in detecting patients with the highest probability of pulmonary embolism, necessitating a confirmation by computed tomography with pulmonary angiography. However, a focused cardiac and thoracic ultrasound investigation is useful for the differential diagnosis of dyspnea and chest pain in the ED.

Abstract
Transoesophageal echocardiography (TEE) has become a fundamental tool in modern cardiothoracic anaesthesia. It has an indisputable role in coronary valve surgery and revascularisations with severe impairment of ventricle function. It helps in making diagnoses that can optimise the surgical strategy and to minimal invasively dynamically monitor volaemia and cardiac function during the post-operative period, detecting complications unobservable by other methods. The McConnell sign, visualised using TEE as an akinesis of the right ventricular free wall, with a normal apex motility and enlargement of the right cavities, is characteristic of right ventricular (RV) dysfunction. This sign has a 77% sensitivity and 94% specificity for the diagnosis of acute pulmonary embolism (APE). The case is presented of a 53-year-old man scheduled for aortic valve and ascending aorta replacement surgery, with a history of severe valve aortic stenosis, aortic root and arch aneurysm, and with normal coronary arteries. Post-cardiopulmonary bypass (CBP), the patient presented with haemodynamic instability, with the TEE showing a typical image of the McConnell sign, with no pulmonary hypertension. This enabled making an early diagnosis of acute RV ischaemia, that led to a change in the surgical plan, the performing of coronary revascularisation surgery. As a result, the McConnell sign, which describes the characteristics of RV dysfunction, led to making a differential diagnosis between APE, RV infarction and acute myocardial ischaemia.
