Filter by:In this study, the arterial blood pressure waveform was digitized by snapshots or videos of the patient monitor to further estimate advanced hemodynamic parameters, so as to realize continuous and automatic monitoring of advanced hemodynamics on mobile devices to assist anesthesia, with a view to developing an Android/iOS application for mobile devices and application in patient management.
The aim of this study is to compare the effectiveness and safety of ultrasound- guided IJV and supraclavicular SCV cannulation in infants weighing less than 5 kg.
The purpose of this study is to understand changes in heart function (how the heart pumps blood) and blood flow in people who receive general anesthesia during surgery. The researchers are particularly interested in the heart function and blood flow changes in people who experience low blood pressure (hypotension) after receiving anesthesia.
Multi-center, prospective, open label, single arm post-market study to assess the real-world safety and efficacy of BD NRFit™ Spinal Needles, BD NRFit™ Spinal Introducer Needles, and BD NRFit™ Syringes used in an on-market fashion.
The aim of this study is to compare the diameter of Left internal mammary artery and its blood flow by using the pulsatility index before and after the left stellate ganglion block in patients undergoing coronary artery bypass grafting.
More accurate and earlier identification of people at risk of cardiovascular disease (CVD) and neurodegenerative diseases (memory, cognition, dementia) through the appropriate use of biomarkers could lead to earlier initiation of preventive therapies and potentially avoid sometimes fatal events and complications. Biomarkers are useful for determining the risk of disease, but also for establishing a diagnosis. High inter-individual variability hinders the establishment of general laws that can be- used in predictive medicine. In addition to the lack of validation, other limitations are the low participation rate in screening campaigns (regardless of disease) and the relative difficulty, accuracy, cost and time taken to perform the measurements. The perioperative period is a very good time to screen for cardiovascular and neurodegenerative pathologies for several reasons: - Patients come to their anesthesia consultation and to the operating room because they have a direct visible benefit. - the physiological data collected intraoperatively during systematic monitoring are very "rich" and of very good quality because they are not very noisy - The induction of general anesthesia or the onset of locoregional anesthesia and its maintenance represents a strong and reproducible physiological "test" for the cardiovascular and cerebral systems. - The patients are regularly re-examined postoperatively for the follow-up of their pathology and the possible complications are recorded in their file, allowing a short and medium term follow-up. The project aims to validate a biomarker predictive of cardiovascular complications, the pulse wave velocity, and a biomarker predictive of cognitive disorders, the power of the Alpha wave on the electroencephalogram, from the data usually collected during each anesthesia and during the perioperative period. The objective is to build a predictive model of cardiovascular and neurodegenerative risks, possibly combined, on a survival analysis.
The goal of this randomized controlled single blinded study is to compare the effect of the type of anesthesia on gastrointestinal motility in patients scheduled for laparoscopic sleeve gastrectomy. The main question it aims to answer is how do inhalation anesthesia and total intravenous anesthesia effect the gastrointestinal peristalsis during anastomosis. Participants will be American Society of Anesthesiology (ASA) physical status II and III, between 18- 60 ages. Researchers will compare inhalation anesthesia where desflurane is used with total intravenous anesthesia to see if the gastrointestinal motility differs between the groups.
The brain is a highly active organ that requires a large blood flow to function properly. Normally, blood flow is tightly linked to the brain's energy demands. However, during surgery, anesthesia can affect this relationship in different ways. Some types of anesthesia can decrease blood flow to the brain, while others can increase it. Anesthesiologists need to be careful to maintain adequate blood flow to the brain during surgery, especially when blood pressure drops. Drugs may be used to increase blood pressure, but some of these drugs can also affect blood flow to the brain. It is still unclear how to best maintain blood flow to the brain during surgery and how different types of anesthesia and drugs affect this process. The study aims to assess the clinical utility of a new technique that uses light-based neuromonitoring to measure changes in cerebral blood flow and metabolism. The investigators will recruit 80 adult patients undergoing surgery under general anesthesia and randomize them into one of four groups to evaluate the effects of different anesthetic agents and vasopressors on brain hemodynamics and metabolism. The study will include patients over 18 years of age with no history of neurological conditions, substance abuse, or contraindications to cerebral oximetry devices or specific anesthetic agents. The patients will receive standard anesthesia care and be monitored with our light-based neuromonitoring system. This study aims to demonstrate the device's ability to detect changes in cerebral hemodynamic parameters related to anesthesia induction and systemic hypotension. This study will also evaluate the effects of anesthetic maintenance agents and vasopressors on cerebral hemodynamics and neurovascular coupling.
Despite modern day improvements in pain treatment and availability of different analgesic modalities, suboptimal postoperative pain control remains an issue in cardiac surgical patients. Poorly controlled acute postoperative pain is associated with adverse physiological outcomes that impair the recovery of cardiac surgical patients. It is associated with decreased patient satisfaction, delayed postoperative ambulation, and the development of chronic postsurgical pain (CPSP). Intravenous opioids such as fentanyl and morphine have been the mainstay of perioperative analgesia for cardiac surgery, either by intermittent boluses by healthcare staff or through a patient-controlled device (PCA). The primary problem with this mechanism of delivery is that significant fluctuations in serum opioid concentrations can occur, resulting in effects which range from inadequate analgesia to overdose and respiratory depression. In contrast to intermittent administration of short-acting opioids such as morphine and fentanyl, a single dose administration of methadone can be considered.
In recent years, the world of anesthesiology is questioning one of its great dogmas: Are so many hours of strict fasting necessary in patients who are candidates for elective surgeries? The main objective of our clinical trial will be demonstrate whether preoperative oral loading with hydrocarbonate beverages reduces the time of return of intestinal function in the postoperative period compared to water administration and strict fasting in patients undergoing elective radical cystectomy.
