Filter by:The goal of this pragmatic, multi-center, superiority, randomized clinical trial is to compare early treatment with peripheral (through a vein) infused noradrenaline (a natural hormone that increases blood pressure) with fluid only therapy in patients with hypotensive and shock in the Danish Emergency Departments (ED). The main questions it aims to answer are: If early initiated noradrenaline in non-bleeding hypotensive patients presenting in the ED can - Improve time to shock control. - Reduce the need for ICU admittance. - Decrease mortality. Participants will be included by the clinical staff and treated urgently with either noradrenaline or usual treatment during their Emergency Department stay. After completion of the treatment in the Emergency Department, patient data will be extracted from the bed-side measurements, electronic health records and national registers. Patients will be contacted by the research staff 1 year after study inclusion to answer brief questions about their daily physical function and ability to care for themselves. Researchers will compare with patients receiving fluid therapy only, as this is the usual standard of care in Danish Emergency Departments.
Hyperemia with adenosine was an elemental process in FFR examination. Adenosine injection will induce some discomfort, and increase cost expenditure. Nitroglycerine will induce an acute drop of Pd/Pa, and this lowest Pd/Pa was determined as NTG-Pd/Pa. NTG-Pd/Pa has a linear relationship with FFR value and has a good diagnostic accuracy to predict FFR≤0.80 in our recent study. There is only one prospective study report on the relationship between NTG-Pd/Pa and FFR. In this study, we aim to evaluate the safety of NTG-Pd/Pa, the repeatability and dose-response of this novel index. Furthermore, we will investigate the diagnostic accuracy of NTG-Pd/Pa, with FFR≤0.8 and Resting full-cycle ratio≤0.89 as ischemic threshold respectively.
This will be a double-blind randomized study, aiming at investigating a fixed rate phenylephrine infusion versus a fixed rate norepinephrine infusion versus placebo in combination with co-hydration with colloids for the prevention of maternal hypotension in elective cesarean section
The aim of this double-blind randomized study will be to compare a fixed-rate prophylactic noradrenaline infusion to a fixed-rate prophylactic phenylephrine infusion during elective cesarean section under combined spinal-epidural anesthesia
