Filter by:Septic shock is a subset of sepsis characterized by a decrease in vascular tone, which contributes to impaired regional blood flow distribution, and leads to organic failure. Besides intravenous fluids and adequate antimicrobial therapy, patients with septic shock require vasopressor support, which can lead to many adverse effects, therefore, non-vasopressor agents that can improve hemodynamic status are needed. In this randomized controlled-study, the investigators will address the efficacy and safety of infusion with methylene blue in patients with septic shock.
Several recent studies point to the possibility of the new coronavirus (SARS-Cov2), which currently causes pandemic COVID-19, to infiltrate the central nervous system (CNS) and cause primary damage to neural tissues, increasing the morbidity and mortality of these patients. A pathophysiological hypothesis for insulting the CNS would be the impairment of cerebral compliance (CC), because elevation of intracranial pressure (ICP), but due to the invasive nature of the methods available for ICP evaluation, this hypothesis has so far not been verified. Recently, a noninvasive technique was developed to evaluate CC (B4C sensor), making it possible to analyse CC in patients outside the neurosurgical environment. Therefore, the main objective of this study was to assess the presence of CC impairment in patients with COVID-19, and observe potential influences of this syndrome on cerebral hemodynamics.
The current COVID-19 pandemic, this is especially since the transmission of SARS-CoV-2 is thought to occur mainly through respiratory droplets generated by coughing and sneezing, by direct contact with contaminated surfaces and because in a large number of patients COVID-19 disease may be asymptomatic. As recommended by the CDC medical personnel should be equipped with full personal protective equipment (PPE) for AGP in contact with suspected/confirmed COVID-19 patient. Therefore, it is reasonable to search for the most effective methods of intravascular access in those conditions.
Acute circulatory failure (ACF) is a common cause of admission in intensive care unit (ICU). Echocardiography is a widespread tool nowadays for the initial assessment and the hemodynamic monitoring. An interesting data from this exam is the Left ventricular outflow tract (LVOT) velocity time integral (VTI), reflecting stroke volume, and therefore cardiac output. A new tool for automated recording has been developped on the VENUE GE echograph. This study aims at assessing this automated measurement of LVOT VTI compared with the classic manual method.
The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been declared a public health emergency of international concern. Hospitalized COVID-19-positive patients requiring ICU care is increasing along with the course of epidemic. A large number of these patients developed acute respiratory distress syndrome (ARDS) according to current data. However, the related hemodynamic characteristic has so far been rarely described.
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a temporary mechanical circulatory support that has been increasingly used over the last decade to restore and maintain adequate end-organ perfusion, with data suggesting improvement in outcome for patients with refractory cardiogenic shock. Nevertheless, VA-ECMO weaning should be questioned every day during patient's support. Indeed, studies have shown that the incidence of severe complications related to ECMO is associated with longer circulatory support duration. Inotropes such as dobutamine are currently used to improve myocardial contractility during VA-ECMO support with the aim to enhance left ventricular ejection, aortic valve opening and to shorten ECMO duration. However, many data suggest an increase in mortality related to predisposition to myocardial ischemia and arrythmias. Levosimendan is a calcium sensitizing inotropic agent with systemic, coronary and pulmonary vasodilatory properties and specific cardioprotective effect without increasing myocardial oxygen consumption. The use of levosimendan in patients undergoing VA-ECMO may therefore be of interest both to reduce the duration of mechanical support and to minimize severe complication with few data suggesting a potential benefit of levosimendan for VA-ECMO weaning and survival in post-cardiotomy low cardiac output syndrome with improvement of endothelial function and hemodynamics. Investigators therefore sought to investigate whether the use of levosimendan improves weaning for patients undergoing VA-ECMO support for refractory cardiogenic shock hospitalized in the surgical intensive care unit (ICU).
40 chronic stroke patients with upper limb spasticity will randomly divided into two groups. First group will receive 3 sessions of radial extracorporeal shock wave therapy (rESWT) with one week apart without cessation of current physical therapy, while the second group will continue to receive conventional rehabilitative program. Assessment will be done at baseline, 2 weeks after rESWT and 3 months after rESWT using Modified Ashworth Scale, Fugl Meyer Assessment for hand function and wrist control, motricity index for pinch grip and Hmax/ Mmax amplitude ratio of flexor carpi radialis muscle.
Study design Observational, single centre, prospective cohort study Planned sample size 100 participants Inclusion criteria The study will evaluate a cohort of participants meeting the following inclusion criteria: 1. admission to the Intensive Care Unit (ICU) after elective and emergency cardiac surgery using cardiopulmonary bypass 2. age 18 years and above 3. arterial, central venous and pulmonary arterial catheters have been inserted as part of routine care Study procedures In addition to routine clinical postoperative data and blood collection, serum renin levels will be analysed on admission, 6 and 24 hours after admission to ICU Study duration 6 months
Although norepinephrine is commonly used and is the recommended agent for the treatment of hypotension in volume-resuscitated hyperdynamic septic shock, Low doses of vasopressin may be added to norepinephrine to maintain arterial blood pressure in refractory septic shock and to decrease exposure to norepinephrine. The aim of the work is to compare the effect of norepinephrine alone and Norepinephrine/vasopressin combination on hemodynamics and tissue perfusion in septic shock patients.
International guidelines recommend Methylene Blue (MB) as a second-line drug in the treatment of norepinephrine refractory vasoplegic shock (VS) after Cardiopulmonary Bypass CPB. Macrocirculatory effects of MB in this setting are now well established but microcirculatory effects of MB remain unknown. The purpose of this study is to assess the micro vascular effects of a single administration of methylene blue (1.5 mg/kg over 30 minutes) for norepinephrine-refractory VS post CPB. Microcirculatory effect will be monitored before and one hour after MB infusion through cutaneous refill time, video microscopy measurements of the sublingual microcirculation and tissue oxygen saturation combined with vascular occlusion test (VOT).
