Filter by:Evaluate the feasibility and quality of automated anesthesia, analgesia and fluid management based on a combination of several physiological variables (bispectral index [BIS], stroke volume [SV], and stroke volume variation [SVV]) using 2 independent physiologic closed-loop systems (PCLS) in patients undergoing high risk vascular surgery
Feasibility trial on the use of a hybrid optical device integrating time-resolved near-infrared spectroscopy (TRS) and diffuse correlation spectroscopy (DCS) for measurement of cerebral oxygen metabolism and blood flow in neonates. The device wil be tested in four settings measuring: 1. Changes in cerebral oxygenation and haemodynamics after birth 2. precision and repeatability 3. The cerebral vaso-reactivity to arterial carbon dioxide 4. Assessment of the user-friendliness and loss of signal in routine care
Since 2011, phenylephrine was recommended as the preferred drug to maintain blood pressure in obstetric anesthesia.Phenylephrine, an α adrenoceptor agonist, can induce peripheral vasoconstriction to maintain blood pressure, while reflexly decrease heart rate and result in cardiac output (CO) reduction.Norepinephrine acts not only as an α adrenoceptor receptor agonist, but also as a weaker β adrenergic receptor agonist. It can elevate blood pressure the same asphenylephrine, meanwhile produce positive inotropic effect including increasing heart rate.Thus, the administration of norepinephrine can maintain blood pressue and avoid the decline of CO. The purpose of this study is to evaluate the effect of norepinephrine and phenylephrine on maternal CO in cesarean section by transesophageal echocardiography.
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.
For patients requiring the heart valve replacement surgery, heart function is injured in different degree.Thus, minimizing the impact of the anesthesia drug on the cardiovascular system has important clinical meanings. Etomidate has slight effect on the cardiovascular system, often used in the induction of anesthesia, however target controlled infusion etomidate in maintenance of anesthesia is less used. So, the trial is designed to observe the application value of TCI etomidate in thoracoscopic mitral valve replacement surgery.
Severe sepsis and septic shock are among the leading causes of morbidity and mortality in patients admitted in the ICU, being responsible for approximately 200000 deaths/year in the USA and 150000 in Europe. Recognizing the early signs of sepsis and the different stages of this condition may lower the associated morbidity and mortality. The hemodynamic profile of the septic shock is characterized by the presence of the distributive shock, on which we can add elements from the hypovolemic and cardiogenic shocks. The objecive of this study is to optimize the volemic resuscitation of the severe septic and of the septic shock patient using two minimally invasive methods of hemdynamic monitoring which both use the same device (Edwards Lifescience). In the same time hemodinamic data will be colected by mesuring the inferior vena cava diameter.
The aim of this study was to investigate the difference in accumulation of AGEs (advanced glycation end-products) in the tissues of individuals who smoke in comparison with individuals who do not as well as of individuals who consume caffeine versus those who do not, and finally to examine the probable differences concerning participants' haemodynamic parameters.
The aim of this study compares hemodynamic and respiratory changes and complications in children who undergoing endoscopy for esophageal balloon dilatation and endoscopy for only control.
During endoscopic sinus surgery (ESS), epinephrine local injection and controlled hypotension is essential in order to increase the visibility in the operative field and reduce the risk. This study is comparing of dexmedetomidine and remifentanil before epinephrine local injection for controlled hypotension during ESS.
This is a Prospective, Double-center, randomized clinical trial. The purpose of the trial is to evaluate the benefit of adding POC US to the management of inpatients admitted to the internal ward with respiratory, cardiovascular or hemodynamic abnormalities.
