This study aimed to assess the effect of sitting and lateral positions on the severity of hypotension during the initiation of spinal anesthesia in elective cesarean section. There will be Sitting and Lateral groups in the study.
Our aim in this treatment was to reveal the effects of remifentanil and dexmetomidine, which we used to provide controlled hypotension in septorhinoplasty surgery, on cardiac electrophysiology. We planned to compare the patients by recording preoperative and postoperative ECGs. We also planned to record the patients' intraoperative blood pressure, saturation, and pulse rate, rickeragitation scale, and vas score.
Hypotension prediction index (HPI) was applied in various types of non-cardiac surgery with convincing benefits of preventing hypotensive events and clinical sequelae. Although HPI was validated in cardiac surgery, its clinical benefits are not proven yet. We aim to evaluate its effects on intraoperative hypotension and postoperative adverse events in cardiac surgery. In this randomized, single-blind trial, we will enroll adults scheduled for elective primary cardiac surgery under general anesthesia. Participants will be randomly assigned to intraoperative HPI-guided or non-HPI-guided hemodynamic management. The primary endpoint is the time-weighted average intraoperative hypotension below a mean arterial pressure threshold of 65 mmHg. The secondary endpoints are postoperative complications.
The goal of this observational study is to learn the how to determine the mean arterial pressure(MAP) or blood pressure level to be maintained during non-cardiac surgery for optimal brain health in patients above the age of 60 undergoing major non-cardiac surgery. The main question[s] it aims to answer are: - Is there a way to tailor the blood pressure to be maintained in such patients during surgery for optimal brain health using non-invasive monitors that check the brains electrical activity, the electroencephalogram(EEG) monitor, and the brain's blood oxygen levels, the cerebral oximetry(CO) monitor? - How much does this optimal blood pressure level vary between patients? Participants will be asked to: - Complete a questionnaire at the time they enroll into the study, as well as a daily questionnaire to help determine their level of thinking and brain health. This questionnaire will be administered by a member of the study team. - They will also have an EEG and CO monitoring sticker placed on their foreheads. This will be connected to a monitor that will collect this data just before, during, and after their surgery. The data collected through these monitors will help us with our study goals.
A clinical trial to evaluate the safety and effectiveness of the Aurora Xi Plasmapheresis System with a new plasma collection volume nomogram.
This is a single-center study retrospectively evaluating a local clinical routine to administer norepinephrine in midline catheters, with regard to complications and patient outcomes
The beach chair position is the most commonly used position during shoulder surgery and offers the surgeon numerous advantages over the lateral decubitus position. However, the beach chair position can also lead to hemodynamic changes, including hypotension and cerebral hypoperfusion. It is therefore the anesthesiologist's job to prevent hypotension during the procedure. The Acumen Hypotension Predictor Index or HPI for short is a software program that can predict the occurrence of low blood pressure during surgery shortly before it occurs. Studies have already demonstrated the effectiveness of HPI in various operations, where hypotension is defined as a mean arterial blood pressure < 65mmHg for at least 1 minute. To our knowledge, the low blood pressure prediction index has not yet been investigated for the prevention of low blood pressure in shoulder surgery in the beach chair position. The HPI is built into a monitor that is switched on in addition to the standard monitoring for monitoring blood pressure, pulse, saturation, among other things. The monitor gives a signal when an episode of low blood pressure will occur within 15 minutes. This gives the anesthesiologist the opportunity to anticipate in time so that the occurrence of low blood pressure can be avoided. Goal The aim of this study is to evaluate the efficacy of the HPI in predicting and reducing the incidence of hypotension during shoulder surgery in the beach chair position. Procedure A total of 144 patients will participate in this study. Patients will be randomized to the intervention group or the control group according to a 1:1 allocation. In addition to standard monitoring, the HPI monitor will be turned on for all patients. For patients in the control group, the HPI monitor screen will be blinded and the alarms muted. Patients between 18 and 85 years of age with a BMI ≤ 40 kg/m2 undergoing elective shoulder surgery are eligible for the study.
