The Impact of Preoperative Fasting Period on Cardiac Index Variability After Anesthesia Induction in Pediatric Patients

The Impact of Preoperative Fasting Period on Cardiac Index Variability After Anesthesia Induction in Pediatric Patients

The minimum period of fasting recommended by the 'American Society of Anesthesiologists' for the preoperative period is 6 hours for solid foods and 2 hours for clear liquids. Knowing the effect of preoperative fasting time on intravascular volume status may lead us to determine the amount of fluid to be administered intraoperatively. Cardiac preload static indicators are often insufficient to predict the need for fluid and are often measured by invasive methods. Knowing the adequacy of the preload is important in anesthesia practice; there is no hemodynamic benefit of fluid replacement in non-responsive patients. In this study, the investigators aimed to determine the effect of preoperative fasting period on cardiac index change after anesthesia induction in pediatric patients aged 5-12 years. The primary implication of this study is to determine the fasting period of fluid evacuation by assessing patients' intravascular volume status.
