Filter by:The investigators aimed to establish current practice of application and monitoring of vasoactive and inotrope Drugs in non-cardiac surgery patients.
This is an investigator-initiated, single-center, single-arm prospective study to compare non-invasive hemodynamic assessment using transthoracic echocardiography (TTE) and lung ultrasound (LUS) and hemodynamic assessment using PAC. Patients who have been hemodynamically assessed using PAC will be invited to participate. Each patient will undergo TTE and LUS immediately after first invasive assessment, and again daily after PAC assessments.
Interventional Trial to determine the Effect of different PEEP levels on Cardiac output and right-ventricular function in mechanically ventilated children < 5 years of age with congenital heart disease.
Postoperative pain after craniotomy is an important clinical problem as it can lead to hypertension and increased intracranial pressure. Multimodal analgesia methods are performed by anesthesiologists in different ways depending on the anesthetist's preference. In addition, both techniques have been shown in studies to provide intraoperative hemodynamic stabilization in addition to their effects on postoperative pain. Although there are many studies on both techniques, the number of studies comparing scalp block with infiltration technique is very limited. Therefore, postoperative use of scalp block and incisional infiltration for postoperative pain after craniotomy is recommended.
Hemodynamic evaluation during pediatric anesthesia is essential to care management. Intraoperative cardiovascular instability is frequent in major surgeries, and appropriate monitoring is necessary to ensure safe anesthetic conduction and promptly detect changes in blood pressure, cardiac output, blood volume, and organ perfusion. In this context, advanced hemodynamic monitoring, continuous measuring, and estimating various parameters can allow a more specific hemodynamic profile and help identify the causal mechanisms of its variability. Moreover, the reference ranges of hemodynamic values in different pediatric ages and how to best monitor hemodynamic status in pediatrics are still debated. Surgical treatment of craniosynostosis is usually performed at an early age, between 3 and 8 months of age. The operation is burdened by a high risk of hemodynamic instability related mainly, but not only, to potential substantial hemorrhagic losses. This study aims to characterize the hemodynamic events occurring during corrective craniosynostosis surgery, recorded simultaneously with standard monitoring and Pressure Recording Analytic Method (PRAM), and to analyze the paired measurements.
The goal of this prospective observational study is to develop and utilize an Artificial Intelligence (AI) model for the prediction of postoperative sepsis in patients undergoing abdominal surgery. The main questions it aims to answer are: 1. Can a remote AI-driven monitoring system accurately predict sepsis risk in postoperative patients? 2. How effectively can this system integrate and analyze multimodal data for early sepsis detection in the surgical ward? Participants are equipped with non-invasive PPG-based wearable devices to continuously monitor vital signs and collect high-quality clinical data. This data, along with demographic and laboratory information from the Electronic Health Record (EHR) of the hospital, are used for AI model development and validation.
This is an observational study in patients who require clinical anesthesia. The main purpose of this study is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by different types of anesthesia. Subjects who require clinical anesthesia for a clinical MRI and for whom the use of anesthetics for the exam are in clinical equipoise are asked to join the study. All eligible subjects will be asked to provide informed consent before participating in the study.
FAME-n aims to improve perinatal care by introducing new approaches to fetal and neonatal heart assessment. Better identification of high-risk deliveries requiring intervention will reduce perinatal asphyxia-related illness and death. Neonatal hemodynamics may be improved by early detection of instability of the heart and circulation. Innovative use of technology enables characterization of normal and abnormal cardiovascular transition in a significantly larger number of fetuses and newborn infants than what was previously possible. The methods used may have broad generalizability and applicability in perinatal, neonatal and pediatric medicine. In September 2023, the project was expanded with an obstetric arm called Epidural analgesia: Fetal Oxygenation and Maternal Oxygenation (Epi-FOMO). In Epi-FOMO, the relationship between maternal breathing and arterial blood gases during labour, and umbilical cord blood gases and neonatal outcomes (as specified in FAME-n) will be investigated.
Data comparing prilocaine vs bupivacaine in equipotent doses in the elderly are lacking; therefore, the study will compare the effect of prilocaine vs bupivacaine on hemodynamics in spinal anesthesia for geriatric patients undergoing endoscopic urological surgeries
The goal of this interventional study is to check the effectiveness of nebulized Dexmedetomidine in preventing the rise in blood pressure and heart rate in patients undergoing General Anesthesia. The study will be conducted in patients presenting for elective surgery either healthy or having co-existing medical conditions which affect their daily living to a moderate extent. These participants will require general anesthesia for their surgical procedure. General Anesthesia will make the patient unconscious, unable to breath and protect his airway. One way to provide airway and ventilatory support to such patient is by placing endotracheal tube into the patient's windpipe and for that direct laryngoscopy is performed. Direct laryngoscopy is one of the most painful stimulus a person can receive. Therefore like any other thing that causes pain it leads to a rise in blood pressure and heart rate. This can be harmful to the person suffering from cardiac disease. As a result one must blunt this painful response while providing adequate airway support to the patient needing General Anesthesia. There are number of drugs which can be used for this purpose. They can be given Intravenously or directly into the patient upper airway so that they can make the area numb. One of the drugs which is used for this purpose is Dexmedetomidine. In this study Dexmedetomidine will be nebulized and directly deliver to the patient's airway just like an asthmatic receives medication from inhaler devices. After giving sufficient time for drug to work, airway will be secured with endotracheal tube using direct laryngoscopy and the degree of rise in Blood Pressure and Heart rate of the patient will be observed. The results will be compared with a control group receiving a substance which looks like a drug but has no effects.
