Filter by:Vasoplegic syndrome after cardiac surgery is common and is associated with increased morbidity and mortality. It is characterized by early and prolonged arterial hypotension, with preserved cardiac output and low systemic vascular resistance. Vasoplegic syndrome therefore shares pathophysiological features with septic shock. There are no data in the literature on the function of the hypothalamic-pituitary-adrenal (HPA) axis during vasoplegic syndrome after cardiac surgery. In situations of acute stress and systemic inflammation, relative adrenal insufficiency has been reported in the most severe patients, particularly those in septic shock. The term ""CIRCI"" (Critical Illness-Related Corticosteroid Insufficiency) is currently defined as an increase in total plasma cortisol of less than 9 µg/dl after stimulation with 250 µg tetracosactide (synthetic ACTH), or a basal total plasma cortisol level of less than 10 µg/dl. However, recent studies have called into question the usefulness of the cosyntropin stimulation test for exploring the HPA axis in intensive care patients. Tandem mass spectrometry (LC-MS/MS) assays can be used to measure steroid metabolites (steroidome), enabling more precise exploration of the corticotropic axis. The aim of this study is to evaluate, on an exploratory basis, the impact of the presence of a post-cardiac surgery vasoplegic syndrome on adrenal function by steroidome mapping (LC-MS/MS).
Several studies have described the use of alternative drugs as methylene blue (MB) (3) other than the standard limited options of the use of vasopressors and systemic corticosteroids (4) especially in the face of increasing incidence of vasoplegic syndrome. Hydroxycobolamin (HCO) has been used for treating cyanide poisoning for more than 40 years. Persistant and significant hypertension occurred as a result of the ability of (HCO) to bind nitric oxide (NO) to form nitrocobalamin. In this prospective randomized controlled trial, we hypothesized that the prophylactic use of HCO in high risk patients after CPB may decrease the incidence of vasoplegia.
We want to measure the amount of a hormone called renin in people's bodies before and after they have major abdominal surgery. We want to see if changes in renin levels are connected to problems with blood flow, unstable blood pressure, and kidney damage after surgery.
This observational study investigates the effect of endotoxinemia on the postoperative incidence of vasoplegia or vasoplegic shock in patients undergoing cardiac surgery with the use of cardiopulmonary bypass.
In postoperative cardiac surgery under extracorporeal circulation, the patient may develop a vasoplegic syndrome, characterized by arterial hypotension (mean arterial pressure (MAP) < 65 mmHg); a decrease in vascular resistance and a cardiac output that may be normal or increased, and increased postoperative mortality/ International recommendations recommend the prescription of noradrenaline as a first-line treatment to reduce morbidity and mortality. However, excess norepinephrine or duration of exposure is also deleterious. The Acumen IQ device (Edwards Lifesciences) allows the calculation of a predictive index of arterial hypotension episodes (predictive hypotension index, HPI). HPI could improve norepinephrine weaning by preventing episodes of arterial hypotension or detecting preload dependence, thus avoiding the transient increase in norepinephrine during hypotension. This is a single-center, prospective, open-label, randomized, controlled, 2-group, parallel, intention-to-treat study. The aim was to evaluate the superiority of a new decision algorithm, based on the HPI delivered by the Acumen IQ device, to reduce the duration of norepinephrine administration in post-cardiac surgery vasoplegic shock. The duration of the interventional protocol is 72 hours. To evaluate the clinical impact of the protocol, the time of the study will be 30 days. Several follow-up visits will be performed (end-of-protocol day, discharge day, and at D30 of inclusion) to collect clinical, biological, and HPI monitoring data.
This study investigates the question of whether there are differences in the plasma concentration of hormones of the RAAS-axis between patients undergoing on-pump cardiac surgery and those receiving off-pump surgery
The incidence of postreperfusion syndrome (PRS) and vasoplegic syndrome (VS) is unknown, and occasionally can be confused since these syndromes share some hemodynamic characteristics. In these cases, monitoring with Swan Ganz catheter may be useful to make the differential diagnosis. The main outcome was to analyze reperfusion syndrome and vasoplegic syndrome in patients receiving vasoactive support during liver transplant surgery, in terms of incidence, risk factors and postoperative complications.
This is a randomized, double blind, multicenter study following surgery with extracorporeal circulation to compare blood pressure optimization with vasopressin versus noradrenaline. It is planned to include 840 patients in order to have 420 patients with vasoplegic syndrome. The primary objective of this study is to determine whether the use of vasopressin to maintain blood pressure following cardiac surgery decreases the number of patients with acute renal failure and/or death compared with the usual use of norepinephrine. Participation in the study involves daily follow-up at D1, D2, and D7 of the onset of the syndrome and then follow-up at D30 and D90.
This study looks for a correlation between microRNAs (miRNAs) and vasoplegic syndrome after on-pump coronary artery bypass surgery.
The aim of this study is to evaluate whether adding angiotensin II to the standard of care is superior compared to the standard of care alone with respect to kidney damage (personalized approach) after cardiac surgery.
