Filter by: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.
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.
Vasoplegic syndrome is characterized clinically by reduced systemic vascular resistance and normal or increased cardiac output. It is principally observed in cardiovascular and orthopedic interventions and is characterized by a systemic inflammatory response with the inability of the vascular endothelial muscles to contract and a resistance to the action of vasoactive drugs. This event extends the length of stay in the critical care area due to the need of vasoactive drugs. The investigators aim to assess the standardized application of midodrine in postoperative patients without sepsis and need of vasoactive drugs in order to reduce the length of stay in critical care area and for extension in hospital.
This study will evaluate if Hydroxocobalamin may be a new and possibly superior treatment for refractory vasoplegic syndrome during liver transplant surgery.
The study team will evaluate the medication Hydroxocobalamin (B12a) for treatment of low blood pressure after cardiac surgery.
Sepsis has been characterised as a dysregulated host response to infection. Adjunctive therapies targeting the inflammatory cascade are being increasingly explored, although to date, have failed to demonstrate consistent benefit, and sepsis continues to manifest poor outcomes. Hospital mortality in patients with septic shock remains as high as 22% in Australia and New Zealand. From a global perspective, 31 million sepsis and 19 million severe sepsis cases are expected to be treated in hospitals all over the world per year. To date, experimental data have reported that both high dose intravenous vitamin C and corticosteroids attenuate the acceleration of the inflammatory cascade and possibly reduce the endothelial injury characteristic of sepsis, enhance the release of endogenous catecholamines and improve vasopressor responsiveness. Therefore, the investigators plan to conduct a feasibility pilot prospective, multi-centre, randomised, open-label, trial in ICU patients with septic shock to test whether the intravenous administration of high dose Vitamin C (6g/d), Thiamine (400mg/d) and Hydrocortisone (200mg/d) leads to a more rapid resolution shock and vasopressor dependence.
This single-institution randomized controlled trial prospective will enrolled 48 patients scheduled for an aortic valve replacement. The objective of the present investigation is to determine the role of Polaramine® on reducing hemodynamic instability after separation from cardiopulmonary bypass (CPB) during cardiac surgery. Our hypothesis is that Polaramine® play an important role reducing dysfunction of the autonomic nervous system and hemodynamic stability after separation from CPB.
After cardiac surgery, vasoplegic syndrome is a hemodynamic state characterized by profound hypotension associated with a decrease in systemic vascular resistance. The care of this disease is based on the intravenous administration of a vasopressor, usually norepinephrine. During the recovery phase, weaning of norepinephrine, is an important step in which any lack of preload (blood volume) initial or secondary can be, and increase tissue malperfusion.
