Filter by:The primary objective of the present investigation is to determine the accuracy of a non-invasive non-oscillometric blood pressure wristband device when compared to invasive intra-arterial blood pressure monitors. In an intensive care unit patients who already have an intra-arterial blood pressure monitor in place, this wristband device will be applied and blood pressure readings compared for approximately 15 minutes. Blood pressure readings will be gathered and compared.
Acute renal injury (AKI) is a common complication after cardiac surgery and is associated with worse outcomes. It is now realized that intraoperative hypotension is an important risk factor for the development of AKI. In a recent randomized controlled trial of patients undergoing major noncardiac surgery, intraoperative individualized blood-pressure management reduced the incidence of postoperative organ dysfunction. The investigators hypothesize that, for patients undergoing off-pump CABG, targeted blood-pressure management during surgery may also reduce the incidence of postoperative AKI.
The objective is to compare efficacy of prophylactic norepinephrine bolus versus Infusion in prevention of hypotension which occurs frequently after spinal anesthesia for caesarean section. The authors hypothesize that prophylactic norepinephrine bolus is as effective as infusion in Prevention of hypotension after spinal anesthesia in caesarean section
The purpose of this study is to evaluate the effect of sub anesthetic dose of ketamine on vasopressor (Ephedrine) requirement to prevent maternal hypotension after spinal anesthesia in caesarean section.
The objective of this study is to evaluate the effect of LJPC-501 infusion on mean arterial pressure (MAP) as assessed by standard of care vasopressor dose reduction in pediatric patients with catecholamine-resistant hypotension (CRH). In addition, this study will evaluate the safety and tolerability of LJPC-501 in pediatric patients, evaluate changes in catecholamine and other vasopressor doses over time, evaluate the change in MAP over time, and the change in Pediatric Logistic Organ Dysfunction-2 (PELOD-2) scores.
Maternal hypotension during spinal anaesthesia for Caesarean delivery may bring various adverse effects. It is therefore important to closely monitor hypotension during spinal anaesthesia, however current technology does not allow the blood pressure monitoring to respond in timely manner should there be any occurrence of hypotension. The investigators developed an advanced double-intravenous vasopressor automated system (ADIVA) so as to tackle this issue via novel algorithm to control blood pressure more rigorously with more stable haemodynamic profiles.
Design: Single-center randomized comparison of invasive arterial pressure monitoring vs. arterial pressure monitoring combined with Acumen Hypotension Prediction Index (HPI) software guidance on intraoperative hypotension duration and severity. Aim: To determine whether use of Acumen HPI software guidance to guide intraoperative hemodynamic management in the non-cardiac surgery reduces the duration and severity of hypotension. Primary hypothesis: Our primary hypothesis is that adding Acumen HPI software guidance to the information provided by the invasive arterial pressure monitoring during moderate- to high-risk noncardiac surgery reduces time-weighted average (TWA) intraoperative hypotension below a threshold of 65 mmHg.
The goal of this study is to determine the efficacy of the drug Droxidopa (Northera) in increasing blood pressure in subject with hypotension, low blood pressure, which is classified as blood pressure less than 110/70 in males and 100/70 in females. The first aim is to determine the proportion of subject with Spinal Cord Injury (SCI) who have a normotensive response to Droxidopa. The second is to determine the proportion of subject with SCI who express a hypertensive response to Droxidopa. A Normal blood pressure ranges from 111-139 in males and 101-139 in females and a hypertensive blood pressure is anything higher than 140 in males and females. The study would take place in James J. Peters VA Medical Center (JJPVAMC) and The Icahn School of Medicine at Mount Sinai (ISMMS) in Manhattan, New York.
This study is to assess the blood pressure lowering effect of rice vinegar when consumed over a 12-week period by healthy adults ages 30-65 years old with prehypertension. Study subjects will be recruited online via ClaimIt software platform and randomized to receive either the active rice vinegar-based drink or placebo and will visit the Endothelix research study site in Houston, Texas, 6 times during the study (Week -2, 0, 4, 8, 12 and 16). Here, subjects will undergo blood pressure monitoring, endothelial function, and laboratory assessments.
