Filter by:The purpose of this study is to determine the effects of Angiotension Converting Enzyme Inhibitors (ACE-I) during surgery and in the immediate postoperative period for patients undergoing elective total hip or knee arthroplasty.
Paravertebral analgesia is non-inferior to epidural analgesia for pain control and superior to epidural analgesia in terms of the main complication of hypotension.
The premise of this study is that enteral tranexamic acid will help to maintain small bowel integrity, which is often compromised by critical illness due to inadequate cardiovascular perfusion (i.e., shock), and that maintenance of small bowel integrity will decrease morbidity in critically ill patients.
Orthostatic hypotension is a major complication of hemodialysis and interferes with everyday activities in hemodialysis patients. Since information regarding the use of droxidopa in clinical trials relating to orthostatic hypotension of chronic hemodialysis patients is limited in Taiwan, this study is designed for evaluation the efficacy and safety profile of droxidopa on orthostatic hypotension treatment / prevention in hemodialysis patients.
Induction of general anesthesia induces frequently arterial hypotension. The short term goal of this study is to evaluate if preemptive volume loading prevents such complication.
The HIP trial is a large pragmatic, multinational, randomised trial of two different strategies for the management of hypotension in extremely low gestational age newborns (Standard with dopamine versus a restricted with placebo approach). HYPOTHESIS: A restricted approach to the management of hypotension in extremely low gestational age newborns will result in improved neonatal and long-term developmental outcomes. PRIMARY OBJECTIVE: To determine whether a restricted approach to the management of hypotension compared to using dopamine as first line pressor agent in infants born less than 28 weeks of gestation within the first 72 hrs after birth (transitional period), improves survival without significant brain injury at 36 weeks postmenstrual age (PMA) and improves survival without moderate or severe neurodevelopmental disability at 2 years corrected age.
In hypotensive septic patients with controlled source, an hemodynamic management protocol including hypertonic saline (HS)and terlipressin improves MOD (Multiple Organ Dysfunction) Score by at least 3 points compared to the use of physiologic saline and norepinephrine. The appropriate design for this trial would be factorial. For the time being, will consider de intervention as a whole unit for this pilot study. In the future an appropriately sized factorial multicentric study shall be necessary. Other goals of the pilot study: 1. HS restores preload parameters adequately 2. HS associated with terlipressin normalizes blood pressure in septic shock 3. HS associated with terlipressin maintains plasma sodium levels 130-155mEq/L 4. There is an inverse relationship between plasma sodium and procalcitonin levels 5. HS increases plasma levels of vasopressin (AVP) 6. HS rises levels of cortisol but not of adrenocorticotropic hormone (ACTH)
A subset of patients suffering from chronic fatigue syndrome exhibit symptoms of neurally mediated hypotension. While the underlying pathophysiology of chronic fatigue syndrome is not precisely understood, a dysfunction of the autonomic nervous system is thought to play a role in this subset of patients. In several small studies, subjects within this subset have noted improvement in their chronic fatigue symptoms when treated for their neurally mediated hypotension. As droxidopa acts on the autonomic nervous system and has been shown to ameliorate symptoms of neurally mediated hypotension, it is hypothesized that droxidopa could aid in the treatment of chronic fatigue symptoms. Neurally mediated hypotension has been associated with patients suffering from chronic fatigue syndrome. Droxidopa meanwhile has been approved in Japan for the treatment of the symptoms of neurogenic orthostatic hypotension. As such, it is hypothesized that regulating the autonomic nervous system in patients with Chronic fatigue syndrome may prove to be clinically beneficial.
Aim of this study is to determine the effect of isoflurane versus sevoflurane on blood pressure and systemic vascular resistance.
This study is designed to determine the ED90 for an infusion of phenylephrine to prevent spinal induced low blood pressure in parturients presenting for an elective cesarean delivery. The up-down methodology (UDM) is commonly used study method to determine the dose of a drug that causes the desired effect in over 90% of the subjects to whom it given. For example: the investigators want to know what is the best dose of phenylephrine (from a range of commonly used doses) to prevent a drop in blood pressure during cesarean delivery ninety times out of one hundred when it is given at that dose. The ED90 is the effective dose at which 90% of subjects will have a "positive" response to a phenylephrine infusion, i.e. no drop in blood pressure. The investigators hypothesize that the ED90 will be between 40 - 60 mcg/min. The primary outcome measure is the ED90 for phenylephrine infusions that prevents a drop in blood pressure in women undergoing cesarean delivery.
