Filter by:First described in cardiac surgery, the aortic to radial pressure gradient (ATRAP) is the cause of an underestimation of the aortic pressure with a measure assumed with a radial catheter, and he can concert 1 of 3rd patients. The risks factor well known are small height, previous hypertension, long and difficult surgery, radial artery diameter less than 1.8mm. The ATRAP definition is a pressure difference between radial and femoral (same of the aortic pressure) pressure of 25mmHg on the systolic pressure, or a pressure difference on the mean pressure of 10mmHg, both measures realised by arterial canulation, and with a duration superior than 5 minutes. If this gradient appears in pathophysiological specifics situations, there is a risk of inappropriate administration of vasopressors, with more hospitalisation days, more side effect of vasopressors like an augmentation of myocardial work. The ATRAP is documented in septic shock with a prevalence between 21% and 27%. The ATRAP can appear in shocks, moreover with doses of equivalent norepinephrine of 0.5 µg/kg/min who is use for the definition of refractive shock, the difference between the two pressure is higher if the dose of equivalent norepinephrine is higher than 1µg/kg/min. But the prevalence and risks factors are barely unknowns in this situation. Most of the time, a radial arterial catheter is used for hemodynamic monitoring for his simplicity of utilisation and the lows complications associated. Some medical teams in cardiac surgeries, or in intensive care unit (ICU) for the management of shocks used often radial and femoral arterial catheter. It seems there is no at risk for the utilisation of a radial and femoral arterial canulation. Out of the situation of cardiac surgery, there is a lack of information of the ATRAP, the objective of the study is to evaluate the prevalence of the ATRAP in shock, out of the situation of cardiac surgery.
The goal of this observational study is to learn about blood pressure response to the vasopressor drug vasopressin in people with septic shock. The main questions it aims to answer are: - Are the levels of molecules showing communication between cells different between people whose blood pressure improves and people whose blood pressure does not improve when given a vasopressor medication? - Are measurements found on echocardiography (heart ultrasound) different between people whose blood pressure improves and people whose blood pressure does not improve when given a vasopressor medication? Participants will be asked to contribute one or two blood samples. Participants who are ordered the drug vasopressin will contribute two blood samples. Both samples will be about two tablespoons for a total of about four tablespoons. One sample will be drawn before starting vasopressin infusion and the second sample will be drawn between one and six hours after starting the vasopressor drug infusion. At the same time points, advanced echocardiography pictures will be taken. Participants who are not ordered the drug vasopressin and only ordered the drug norepinephrine will contribute only one sample. At the time the sample is collected, advanced echocardiography pictures will be taken. This research also involves analyzing data obtained during the participant's hospital stay.
Arginine-vasopressin (AVP) is a non-catecholaminergic hormone produced in the hypothalamus and released into the circulation via the neurohypophysis. It has different actions depending on the receptors through which it acts: V1 (vasoconstriction, platelet aggregation, efferent arteriole constriction of the renal glomerulus, glycogenolysis); V2 (water reabsorption, release of von Willebrand factor and factor VIII); V3 (increased cortisol and insulin). Septic shock is the most common cause of vasoplegic shock and its management includes control of the focus, early antibiotic therapy, volume resuscitation, vasopressor therapy, support of various organ dysfunctions, as well as monitoring and follow-up. The Surviving Sepsis Campaign (a global initiative to improve sepsis management) recommends noradrenaline as the first line of vasopressor therapy and early addition of AVP as a second line rather than further up-titration of noradrenaline when signs of hypoperfusion persist, through its action primarily on V1. The rationale for its use in septic shock would be: - endogenous vasopressin deficiency present in septic shock; - as a catecholamine-sparing strategy, reducing the side effects of catecholamines; - its potential nephroprotective effect; - its use should be early. The uncertainties surrounding the use of AVP in septic shock and other types of shock are many, hence the need for this registry.
The goal of this randomized controlled trial is to appraise the impact of intra-aortic balloon pump (IABP) in the treatment of early stages of cardiogenic shock, irrespective of etiology. Findings of this randomized trial may enhance clinical decision making regarding the use of MCS in specific subsets of patients in early stages of cardiogenic shock. The main questions it aims to answer are: - What are the effects of IABP on a composite of clinical endpoints representing clinical deterioration at 30-days in patients presenting with SCAI stage B or C cardiogenic shock? - What is the 1-year clinical outcome (including mortality and hospital admissions for cardiovascular causes) of patients treated with vs. without IABP for early cardiogenic shock? - Is there a difference in efficacy of IABP within the treatment of early cardiogenic shock related to Acute Coronary Syndrome versus non-ischemic causes? - Is there a difference in efficacy of IABP within the treatment of SCAI stage B versus stage C cardiogenic shock? Participants will be 1:1 randomized to IABP support or standard of care (a treatment strategy including inotropes and/or vasopressors but no IABP insertion). Patients will be stratified for Acute Coronary Syndrome/non-ischemic etiology and stage B/stage C cardiogenic shock, following stratification to center. Researchers will compare the group who was randomized to IABP to the control group (i.e. standard of care) to see if there is a difference in the primary trial endpoint after 30-days, including 1) all-cause mortality, 2) escalation to invasive mechanical ventilation, 3) escalation of mechanical circulatory support strategy, 4) acute kidney injury and 5) stroke or transient ischemic attack.
BACKGROUND: As the normal functioning of the body is dependent on oxygen, low blood oxygenation is a acute problem that needs immediate attention. Measurement of blood oxygenation is therefore central to monitor patients and is usually done using light technology with a clip on the finger. Philips manufactures a measuring clip that is designed to measure oxygenation in the nasal wing instead of the finger. The advantage of this is that the nose is not affected as much as the fingers by poor blood flow in the skin, for example caused by cold. The nose is also closer to the heart and lungs than the hand, so changes in oxygenation may be detected earlier. This newer meter is an approved CE-marked product that is available for clinical use, but the next step is to investigate it systematically during and after surgery.
Tissue perfusion has been identified as an early prognosis factor in patients admitted to intensive care. However, little is known about the effects of different hemodynamic interventions performed in clinical routine on peripheral tissue perfusion. The aim of this work is to study the kinetics of CRT and local skin blood flow following therapeutic intervention (fluid challenge, vasopressor or inotropic drug).
The main goal of this study is to look at the performance of the neonatal, infant, and pediatric Philips SpO2 sensors with the Philips FAST Pulse Oximetry technology. Oxygen saturation measurements (SpO2) will be obtained via pulse oximetry and invasive arterial oxygen measurements (SaO2) will be obtained via arterial blood samples as part of your clinical care and assessed by co-oximetry. The study will aim to enroll a diverse population to help us understand the impact of skin pigmentation.
Cardiac Intensive Care Units (CICUs) provide care for a diverse patient population. Understanding the clinical characteristics, analysis of treatment modalities, and prognosis of patients hospitalized in the CICU are important to improve cardiovascular care. The purpose of this registry is to determine the demographics, clinical, treatment, and prognosis of patients hospitalized in the Polish CICUs. Data from this multicenter, prospective observational study will provide more robust data to facilitate quantitative characterization of cardiac care in contemporary Polish CICUs and enable the development of infrastructure for clinical trials in CICUs.
The purpose of the trial is to test if a strategy of resuscitation guided by capillary refill time and individualised clinical hemodynamic phenotyping can improve important clinical outcomes within 28 days in septic shock patients compared to usual care.
A randomized, double-blind, placebo-controlled study on the treatment of refractory distributed shock with angiotensin II injection, with a random ratio of 1:1. Assuming a success rate of 25% for the main therapeutic endpoint in the control group and 50% for the experimental group, a total of 214 subjects will be enrolled, including 107 in the experimental group and 107 in the control group.
