NCT06753097
This is a randomized trial (1) investigating whether continuous finger-cuff - compared to intermittent oscillometric - arterial pressure monitoring reduces the amount of intraoperative hypotension (specifically, from the start of induction of general anesthesia until the end of surgery) in low-to-moderate risk patients having elective non-cardiac surgery.
NCT07134530
This is a single center, randomised and controlled clinical triaI whose aim is to predict and treat in advance, intraoperative hypotension episodes. In particular, the aim of the study is to compare the clinical impact of two different hemodynamic strategies based on the use of different monitoring platforms: the Edwards EV1000 equipped with FloTrac sensor and HemoSphere platform equipped with Acumen Hypotension Prediction Index software and Acumen IQ pressure sensor.
NCT06707428
The present study aimed to determine the effects of compression stockings used during cesarean section on intraoperative hypotension.
NCT05940649
Intraoperative hypotension is common in patients having non-cardiac surgery with general anesthesia and is associated with organ injury and death. The timely treatment of intraoperative hypotension is thus important to avoid postoperative complications. About one third of intraoperative hypotension occurs during anesthetic induction - i.e., between the start of anesthetic induction and surgical incision. Hypotension during anesthetic induction is associated with postoperative acute kidney injury. Unmodifiable risk factors for hypotension during anesthetic induction include age, male sex, and a high American Society of Anesthesiologists physical status class. However, hypotension during anesthetic induction is mainly driven by modifiable factors - specifically, anesthetic drugs that cause vasodilation. In most German hospitals, norepinephrine is the first-line vasopressor to treat hypotension during anesthetic induction. Norepinephrine is usually given as repeated manual boluses of 5, 10, or 20 μg. The continuous administration of norepinephrine via a perfusion pump is usually started only later. It remains unknown whether giving norepinephrine continuously - compared to giving it as repeated manual boluses - reduces hypotension during anesthetic induction. We thus propose to investigate whether giving norepinephrine continuously - compared to giving it as repeated manual boluses - reduces hypotension during anesthetic induction in non-cardiac surgery patients.
NCT05011357
The purpose of this research study is to determine how vasopressors affect a measure of how intravenous fluid is administered in people undergoing surgery who have low blood pressure called Pulse Pressure Variability (PPV). This study will recruit human subjects to undergo simulated hypovolemia called Lower Body Negative Pressure (LBNP) and will receive phenylephrine and placebo, while PPV will be measured in both conditions. This research will help anesthesiologists learn more about how to use PPV in patients undergoing surgery and who need vasopressors.
NCT04894045
The investigators propose a pilot trial to (1) proof the concept that defining the intraoperative mean arterial pressure (MAP) intervention threshold based on the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring) results in clinically relevant (mean nighttime MAP ± 10 mmHg) different target values compared with using an absolute population-derived MAP intervention threshold of 65 mmHg (primary endpoint); (2) investigate if a personalized perioperative blood pressure management is feasibly in multi-center studies, especially if the target values can be sufficiently achieved (secondary endpoint); (3) study the impact of personalized perioperative blood pressure management on the incidence of myocardial injury after non-cardiac surgery (MINS) (exploratory endpoint); (4) study the impact of personalized perioperative blood pressure management on the incidence of acute kidney injury within the first three postoperative days according to the KDIGO (Kidney Disease: Improving Global Outcomes) definition without oliguric criteria (exploratory endpoint).
NCT05671783
The underlying causative mechanism that leads to intraoperative hypotension (IOH) may vary depending on the stage of anesthesia and surgery, which determines different IOH types. Naturally, the incidence and severity of IOH types will differ, as will the incidence and severity of postoperative complications.
NCT05557253
This study is a randomized, controlled trial. A total of 72 patients will be randomized to receive remimazolam anesthesia or balanced anesthesia (propofol + desflurane) during extracranial-intracranial bypass surgery.
NCT04872504
A prospective, open-label and single-center study to determine whether the use of Acumen Hypotension Prediction Index software predicts the occurrence of hypotension.
NCT04025086
This study aims at evaluating if a specific protocol, that can be framed in the innovative concept of Perioperative Goal Directed Therapy (PGDT), based on the evaluation of the Stroke Volume Variation (SVV) - a parameter deriving from the adoption of a minimally invasive advanced hemodynamic monitoring technology with a special sensor called FloTrac® (Edwards) or of a non-invasive monitoring system with the Clearsight® sensor (Edwards) - is able to guarantee a greater precision in the intraoperative management of patients undergoing spinal surgery in prone position.
NCT03837535
Acute myocardial infarction (AMI) is a significant complication following non-cardiac surgery. The investigators sought to evaluate incidence of perioperative AMI, its preoperative and intraoperative risk factors and the outcomes after this complication.
