The Influence of Fasting on Selected Hemodynamic Parameters Measured in a

Status Completed

Clinical Trial Summary

Preoperative fasting is considered to be refraining from taking meals for at least 6 hours and clear fluids for at least 2 hours before anesthesia. On the one hand, it is a procedure that reduces the risk of aspiration of chyme and the occurrence of Mendelson's syndrome, and on the other hand, it is one of the causes of water and carbohydrate disturbances in patients undergoing general anesthesia. Most of them experience some degree of dehydration in the preoperative period. It is associated with a worse prognosis. Due to the negative impact of fasting on homeostasis, as well as significant changes in heart rate in participants in the previous study, we decided to measure the hemodynamic parameters during fasting. The development of impedance cardiography techniques enables the measurement of these parameters by a non-invasive method. After obtaining the participant's written consent to participate in the study, the first measurement of body weight, blood pressure using a non-invasive method and hemodynamic parameters using a non-invasive impedance cardiography method using the Niccomo ™ device (Medizinische Messtechnik GmbH) will be performed in the evening. The subject will then be asked to refrain from food for at least 10 hours and fluid for 6 hours before the next measurement. The next morning, another measurement will be made and the participant will be randomly assigned to one of two groups: subjects in the first group will be asked to refrain from eating and drinking for another 2 hours, while subjects in the second group per os will receive 400 milliliters of PreOp® (Nutricia ™ preparation intended for preoperative dietary management in surgical patients, containing carbohydrates and electrolytes). After another two hours, the third measurement of the tested parameters will be performed. The obtained results will be subjected to statistical analysis consisting in comparing the values of hemodynamic parameters between the studied groups at appropriate measurement points.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
