The Relationship of Preoperative Fasting With Tricuspid Annular Plane Systolic Movement in Female Patients

Background Fasting for 6 hours is required for the patients regarding the preparation of the operation and preparation for anesthesia. It is already known that this fasting period affects volume. Although Tricuspid Annular Plane Systolic Movement (TAPSE) is an echocardiographic parameter showing Right Ventricular (RV) systolic function, its relationship with volume is discussed in recent years. In the present study, the relationship between TAPSE and volume, and whether there is a change in preoperative fasting and right ventricular functions will be evaluated.Methods The study was started between 21.11.2022 and 21.05.2023 in Aydın Maternity and Child Hospital after approval was received from the Non-Invasive Clinical Research Ethics Committee. A total of 21 patients were planned to be included in this prospective observational study. Transthoracic echocardiography will be performed in patients aged 18-65 years who will undergo elective procedures under anesthesia, and in full patients the day before surgery. Those who are pregnant, patients with known or prospective severe valvular disease, severe pulmonary hypertension, acute myocardial infarction, dilated and hypertrophic cardiomyopathy, and non-sinus rhythm will be excluded from the study. Transthoracic echocardiography will be performed on the patients, and the relationship between TAPSE and volume and whether there is a change in preoperative fasting and right ventricular functions will be evaluated.
