Ultrasound emergency lateral-to-medial parasternal pericardiocentesis with high frequency probe in COVID-19: a case report.

Background: The pathological involvement of the heart is frequent in SARS-Coronavirus-2 infection (COVID-19) with various clinical and echocardiographic manifestations during the course of the disease.

Case Summary: A 69-year-old female patient with severe COVID-19-related acute respiratory distress syndrome undergoing mechanical ventilation developed acute left ventricular dysfunction, that successfully improved with vasoactive therapy. After 5 days, she suddenly developed hemodynamic instability due to acute onset of pericardial effusion, which required emergency pericardiocentesis.

The Potential Role of Aerosolized Phosphodiesterase 3 Inhibitor Enoximone in the Management of Coronavirus Disease 2019 Hypoxemia: A Case Report.

Despite the various parenchymal presentation of coronavirus disease 2019 (COVID-19) pneumonia, the involvement of the vascular component, the reduction of perfusion in noninjured part of the lung and secondary right to left shunt play an important role in the genesis of the respiratory insufficiency. We present the case of a 72-year-old woman admitted to Livorno Hospital for severe respiratory insufficiency due to SARS-CoV-2 infection unresponsive to noninvasive in whom administration of nebulized phosphodiesterase 3 (PDE3) inhibitor enoximone was able to improve oxygenation avoiding tracheal intubation. Intravenous infusions of phosphodiesterase inhibitors are commonly used as pulmonary vasodilators in the management of pulmonary hypertension.

Risk factors for ventilator associated pneumonia due to carbapenemase-producing Klebsiella pneumoniae in mechanically ventilated patients with tracheal and rectal colonization.

Background: The aim of this study was to identify the risk factors for ventilator associated pneumonia (VAP) due to Klebsiella pneumoniae carbapenemase-producing K (KPC-Kp) development in ICU patients with documented rectal and tracheal colonization.

Methods: We performed a retrospective, matched case-control study in a medical-surgical ICU (January 2011-December 2013) comparing 30 patients who developed KPC-Kp VAP during the ICU stay to 60 colonized patients not developing KPC-Kp VAP. Analysed risk factors included: age, sex, SAPS II and SOFA scores, comorbidities, type and length of antibiotic therapy, previous non KPC-Kp infections, time between admission to rectal and tracheal colonization.
