Filter by:COVID-19 may cause severe pneumonitis that require ventilatory support in some patients, the ICU mortality is as high as 62%. Hospitals do not have enough ICU beds to handle the demand and to date there is no effective cure. We explore a treatment administered in a randomized clinical trial that could prevent ICU admission and reduce mortality. The overall hypothesis to be evaluated is that HBO reduce mortality, increase hypoxia tolerance and prevent organ failure in patients with COVID19 pneumonitis by attenuating the inflammatory response.
COVID-19 infection is overwhelming Italian healthcare. There is an urgent need for a solution to the lack of ICU beds and increasing deaths day after day. A recent retrospective Chinese paper (JAMA Intern Med, online March 13, 2020) showed impressive positive effect of methylprednisolone (MP) on survival of SARS-CoV-2 critically ill patients. Moreover, the Italian Infectious Disease leading institution guidelines for COVID-19 clinical management included as an option for patients with "incipient worsening of respiratory functions" methylprednisolone treatment at an approximate dose of 80mg. The main objective of this multi-centre observational trial is to analyse the association of low dose prolonged infusion of methylprednisolone (MP) for patients with severe acute respiratory syndrome with composite primary end-point (ICU referral, need for intubation, in-hospital death at day 28).
In this prospective study of 60patients, we tested the hypothesis That markedly elevated levels of plasma von Willebrand factor (VWF) a marker of endothelial cell injury might predict the development of acute respiratory distress syndrome (A.R.D.S) in risky patients. We compared our result to IL.6 as control biomarker for A.R.D.S development. Acute lung injury was quantified on two -point scoring system (Berlin definition of ARDS and Murray score of acute lung injury). Plasma levels of both vWF and IL.6 were be measured on T=0 i.e. (at start of the study once the patient considered to be risky for A.R.D.S development to obtain their baseline levels), T=48 (after 48 hours), and T=72 (after 72 hours).
The outbreak of Covid-19 started several clinical trials and treatment experiments all over the world in the first months of 2020. This study investigates reports of adverse events related to used molecules, including but not limited to protease inhibitors (lopinavir/ritonavir), chloroquine, azithromycin, remdesivir and interferon beta-1a. Analyses of reports also include the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).
A advisory will be activated in the ICUs patient data management system. The trial will be conducted as observational cohort trial. During the first six month all patients with a LIPS ≥ 4 will be included in the control group. No change of care is needed. In a second phase during the next six months, all patients with a LIPS ≥ 4 will be included into the advisory group where advisories will be shown in the patient data management system. To create this advisory, a clinical advisory rule is executed every 4 hours and the appropriate advisory text is calculated. If the defined threshold values (driving pressure ≥ 15mbar) are reached, then the advisory displays a recommendation to rethink the patient's ventilation strategy. Furthermore, permissive hypercapnia and oxygen saturating limits considered as safe will be given. (paCO2: 55mmHg, pH: 7.25, paO2: 80 mmHg, SaO2: 92%)
Diagnosis and treatment of the hypoxic respiratory failure induced by severe atelectasis with the background of acute lung injury is challenging for the intensive care physicians. Mechanical ventilation commenced with grave hypoxemia is one of the most common organ support therapies applied in the critically ill. However, respiratory therapy can improve gas exchange until the elimination of the damaging pathomechanism and the regeneration of the lung tissue, mechanical ventilation is a double edge sword. Mechanical ventilation induced volu- and barotrauma with the cyclic shearing forces can evoke further lung injury on its own. Computer tomography (CT) of the chest is still the gold standard in the diagnostic protocols of the hypoxemic respiratory failure. However, CT can reveal scans not just about the whole bilateral lung parenchyma but also about the mediastinal organs, it requires the transportation of the critically ill and exposes the patient to extra radiation. At the same time the reproducibility of the CT is poor and it offers just a snapshot about the ongoing progression of the disease. On the contrary electric impedance tomography (EIT) provides a real time, dynamic and easily reproducible information about one lung segment at the bed side. At the same time these picture imaging techniques are supplemented by the pressure parameters and lung mechanical properties assigned and displayed by the ventilator. The latter can be ameliorated by the measurement of the intrapleural pressure. Through with this extra information transpulmonary pressure can be estimated what directly effects the alveoli. Unfortunately, parameters measured by the respirator provide only a global status about the state of the lungs. On the contrary acute lung injury is characterized by focal injuries of the lung parenchyma where undamaged alveoli take part in the gas exchange next to the impaired ones. EIT can aim the identification of these lesions by the assessment of the focal mechanical properties when parameters measured by the ventilator are also involved. The latter one can not just take a role in the diagnosis but with the support of it the effectivity of the alveolar recruitment can be estimated and optimal ventilator parameters can be determined preventing further damage caused by the mechanical stress.
Intracranial hemorrhage is is a rare, but critical incident in patients with acute lung failure undergoing ECMO therapy. Predictors of intracranial hemorrhage are yet to be defined to identify patients at (high) risk. This retrospective analysis investigates the predictive value and validity of parameters and specific risk factors of critically ill ARDS patients treated with ECMO.
According to the anatomical proximity of the heart temporarily elevated intrathoracic pressures may have direct and indirect effects on the cardiovascular system. Undesirable hemodynamic effects of a recruitment maneuver primarily arise from the transiently increased airway pressure, manifesting in decreased right heart filling, increased pulmonary vascular resistance, a drop in left ventricular systolic transmural pressure, right and left heart ventricular interactions and subsequent changes in cardiac index. These effects can be more pronounced in patients suffering from ARDS, a condition commonly accompanied by hemodynamic instability. The complex pathophysiological changes account for why routine intensive care monitoring, such as invasive arterial blood pressure or central venous pressure monitoring is insufficient to follow hemodynamic changes under recruitment maneuver. Previous studies by the same research team confirmed that the alveolar recruitment maneuver improves oxygenation in patients with moderate-to-severe hypoxemic respiratory failure under pressure supported ventilation. Following recruitment maneuver, arterial oxygenation increased in 74 % of all patients. However, there is lack of information regarding the actual degree of changes in transpulmonary pressure and the consequent hemodynamic alterations. The primary aim of the study is to evaluate precisely the transpulmonary pressure changes during recruitment in patients with severe hypoxemic respiratory failure ventilated in pressure support mode following insertion of a balloon-catheter into the esophagus. In the meantime, hemodynamic changes are monitored by PiCCO and transthoracic echocardiography, and lung field aeration by electric impedance tomography.
It is hypothesized that instillation of Liothyronine Sodium (T3) into the airspace will be safe, well tolerated, and will increase alveolar fluid clearance and decrease inflammation in patients with ARDS, reflected in improved oxygenation index (OI) and oxygenation saturation index (OSI).
This study is an observational study. Investigate the relationship of oxgenation and lung regional ventilation and perfusion assessed by the indicator based-EIT method in the critically ill patients in ICU
