View clinical trials related to Preoperative Fasting.
Filter by:This study aims to evaluate the permissive amount and time limit of clear fluid intake for preoperative fasting.
The purpose of this study is to investigate whether intermittent fasting before surgery improves insulin resistance around the time of surgery, compared to carbohydrate drinks and standard fasting before surgery.
The investigators evaluate gastric emptying time of common Korean meals (rice, noodles) in healthy volunteers.
Preoperative fasting is mandatory for anesthetic induction. This period of fasting is probably greater due to delays in the surgical theater and changes in daily operation schedules.Investigators want to resarch between the prescribed and the actual preoperative fasting time.
Fasting (according to ASA, ESA or institutional guidelines) is an important strategy to minimize the risk of regurgitation, vomiting and pulmonary aspiration during general anaesthesia; the effect of fasting time for clear fluid on gastric pH in children is goal of this study and can be investigated in children undergoing elective procedures in general anaesthesia and intubation without inconvenience or additional invasive procedure and hence without additional risk Hypotheses: Gastric pH is higher in children that drink clear fluids until premedication before anaesthesia induction than in those that drink until 2 hours before anaesthesia induction
