Hypertension Clinical Trial
Official title:
The Importance of Preoperative Arterial Stiffness Measurement in Predicting Hemodynamic Changes in Hypertensive and Normotensive Patients Undergoing Spinal Anaesthesia
The aim of this study is to investigate the importance of pulse wave velocity, an indicator of arterial stiffness, in predicting hemodynamic changes in normotensive and hypertensive patients undergoing spinal anesthesia.
The prospective cross-sectional study will be carried out between September 1, 2021 and September 1, 2022 at Aydin Adnan Menderes University Faculty of Medicine. Patients aged eighteen and over who will undergo lower extremity surgery under spinal anesthesia will be included in the study. During the preoperative evaluation, the patient will be asked about age, weight, height, smoking and alcohol use history. At the same time, hypertension disease (if any, drugs used), diabetes (if any, drugs used), hyperlipidemia (if any, drugs used) and other diseases and drugs used will be recorded. Before surgery, hemodynamic data (systolic arterial blood pressure, diastolic arterial blood pressure, mean arterial blood pressure, heart rate and oxygen saturation), arterial stiffness measurement (pulse wave velocity) will be evaluated in the patient preparation room. Arterial stiffness measurement will be made with the oscillometric mobil-o-graph device in the anesthesia department. Hemodynamic data is recorded by the anesthesia device 1.,3.,5.,10.,20. minutes during surgery. Intraoperative hypotension is accepted as a 20% reduction in systolic arterial blood pressure evaluated before anesthesia. Using this data recorded on the monitor, reductions of 20% or more in systolic arterial blood pressure will be recorded as hypotension. ;
