Purpose: There is evidence that COVID-19 can have a clinically significant effect on the right ventricle (RV). Our objective was to enhance the efficiency of assessing RV dilation for diagnosing ACP by utilizing both linear measurements and qualitative assessment and its usefulness as an independent predictor of mortality.

Methods: This is an observational, retrospective and single-center study of the Intensive Care Unit of the Sanatorio de Los Arcos in Buenos Aires, Argentina from March 2020 to January 2022.

Purpose: The passive leg raising test (PLR) is a noninvasive method widely adopted to assess fluid responsiveness. We propose to explore if changes in the carotid flow assessed by echo-Doppler can predict fluid responsiveness after a PLR.

Methods: We conducted a performance diagnostic study in two intensive care units from Argentina between February and April 2022.

Background: Real-time ultrasound (US)-guided venipuncture has become the standard of care due to its reduced complications and higher success rate. There are various techniques for US-guided cannulation of the internal jugular vein (IJV); the transversal and longitudinal views are the most widely used. There is a less commonly used technique that combines the benefits of both methods.

Traumatic brain injury (TBI) is a worldwide public health concern given its significant morbidity and mortality, years of potential life lost, reduced quality of life and elevated healthcare costs. The primary injury occurs at the moment of impact, but secondary injuries might develop as a result of brain hemodynamic abnormalities, hypoxia, and hypotension. The cerebral edema and hemorrhage of the injured tissues causes a decrease in cerebral perfusion pressure (CPP), which leads to higher risk of cerebral ischemia, herniation and death.

Mechanical ventilation in prone position is a strategy that increases oxygenation and reduces mortality in severe ARDS. The hemodynamic and cardiovascular assessment of these patients is essential. Transthoracic echocardiography (TTE) is a widely used tool to assess hemodynamics in critical care, but the prone position is thought to limit adequate TTE views and goal-oriented measurements.

Transthoracic echocardiography (TTE) is a fundamental tool for hemodynamic monitoring in critical patients. It allows evaluating the left ventricle's stroke volume based on the measurement of the velocity-time integral (VTI) of the left ventricle outflow tract (LVOT). However, in the intensive care unit obtaining adequate echocardiographic views may present a challenge.

Purpose: The passive leg raising test (PLR) produces a reversible increase in venous return and, if the patient's ventricles are preload dependent, in the cardiac output. As this effect occurs in seconds, the transthoracic echocardiography is optimal for its real time assessment. The utility of the PLR for monitoring fluid responsiveness through the measurement of the left ventricle outflow tract velocity-time integral (LVOT VTI) in an apical 5-chamber view is well stablished.

Purpose: The velocity time integral (VTI) of the left ventricular outflow tract (LVOT) obtained in the apical view by echocardiography can be regarded as a surrogate for the stroke volume. In critically ill patients it is often difficult to obtain an appropriate apical view to assess the VTI. The subcostal view is more accessible, but while it allows a qualitative assessment of the heart, is not adequate for estimating a reliable LVOT VTI, given the inappropriate angle between the Doppler signal and the flow through the LVOT.

Purpose: Severe Covid-19 pneumonia frequently presents with infective complications as bacterial and fungal infections, nosocomial maxillary sinusitis is one of them. We describe the role of ultrasonography in the diagnosis of nosocomial maxillary sinusitis in patients undergoing mechanical ventilation due to severe Covid-19 pneumonia.

Methods: Patients with severe pneumonia due to Covid-19 requiring mechanical ventilation and had maxillary sinus occupation by ultrasonography were retrospectively enrolled at intensive care unit of Sanatorio De los Arcos, Buenos Aires, Argentina, between March 2020 and May 2021.

Background: An extremely elevated erythrosedimentation rate (ESR), defined as equal or higher than 100 mm/h, has been linked to serious underlying conditions, such as infections, connective tissue and oncologic disease.

Aim: To analyze a group of patients in order to determine the underlying diagnosis and the characteristics associated with extremely elevated ESR in our environment.

Methods: Cross-sectional study of adult patients, who presented with at least one ESR equal or higher than 100 mm/h at Hospital Italiano, in Buenos Aires (Buenos Aires, Argentina) between January 2002 and August 2014.
