Filter by:Oral supplements (OS) containing carbohydrates are being used 2h before anesthesia. The addition of a nitrogen source would improve these drinks designed for the abbreviation of preoperative fasting. The gastric emptying of an oral supplement containing whey protein in addition to carbohydrates was investigated. This is a randomized crossover study including six healthy young volunteers who were submitted to abdominal MRI in 3 phases: 1) after a overnight fast, 2) after drank 200 mL of an OS containing whey protein and carbohydrates (no lipids), and 3) 3h after ingestion of the mentioned OS. The gastric residual volume (GRV) will be evaluate by MRI. The overall findings would allow us to conclude whether the GRV, assessed by MRI, in healthy young volunteers after three hours of the ingestion of 200 ml of an oral supplement containing carbohydrates associated with whey proteins is similar to the GRV found after an overnight fast. This pilot study will add important information to allow future randomized trials including an arm with patients undergoing elective surgical procedures with a 3h fasting after the ingestion of an OS containing whey protein and carbohydrates.
We investigated the relationship between fasting times and delirium in children undergoing MRI under anesthesia. Paediatric Anaesthesia Emergence Delirium (PAED) scale, last oral intake time and type of food (solid-liquid) and fasting time, laryngospasm, desaturation (SpO2 <95%), bradycardia, allergy, nausea and vomiting were recorded.
The goal of this clinical trial was to identify if duration of acute calorie restriction (CR)/fasting or combination CR with cold stimuli have any effects on mental and physical health-related markers, and to clarify if different fasting strategies have any effect on cognitive and motor functioning efficiency in different genders. The main questions it aims to answer were: - Does fasting duration have any effect on fasting evoked responses? - Does cold interventions can modulate fasting evoked responses? - Does sex have any effect on acute fasting evoked responses? For the first part, participants were randomly classified into 4 groups: two experimental groups: 2-days of CR (0 kcal diet) and 6-days of CR (0 kcal diet), and two control groups: 2-days or 6-days usual diet. For the second part, participants were randomly assigned to undergo the following conditions: 2-days of CR with two 10-min whole-body cold-water immersions on separate days, 2-days of CR without cold-water immersion, 2-days without CR with two 10-min whole-body cold-water immersions on separate days, or 2-days of the usual diet without cold-water immersion in a randomized crossover fashion. Changes in anthropometric characteristics, perceived stress, metabolism, overall health (total blood count, sex hormones, etc.), psycho-emotional state, cognitive and motor functions were examined.
It is well evidenced in the literature that fasting aerobic exercise generates a series of metabolic differences when compared to exercise performed in the fed state, including the use of fats predominantly as an energy source. Consequently, increases in adaptations to aerobic training, related to health and physical performance, are observed when sessions are performed in the fasted state. In relation to resistance training, the evidence is limited. There is a lack of data in the literature regarding the effects of fasting on resistance exercises and whether this practice may reflect in losses or improvements in morphological and neuromuscular adaptations related to resistance training. Thus, the aim of the present project is to compare the effects of resistance training performed in the fasted state compared to the fed state during 12 weeks on body composition and physical performance in young adults. Thirty-four eutrophic or overweight individuals, not engaged in regular resistance exercises, aged between 20 and 40 years, will be recruited. They will be put on a standard customized diet and will perform 2 weekly sessions of resistance exercise after overnight fasting (10 to 12 hours) or in the fed state, for 12 weeks. Before, in the middle and after this period, evaluations of body composition, muscle thickness and quality, maximum dynamic strength and maximum power will be analyzed. Comparisons will be performed using Generalized Estimating Equations (GEE), adopting the factors group (2 stratifications) and time (3 stratifications). All results will be expressed as mean and standard deviation and the accepted significance level will be 5%.
Serial gastric ultrasound assessments to assess the effect of fasting for 4 hours on gastric volume in mechanically ventilated patients in the ICU fasted for extubation.
This double-center, prospective, interventional study aims to include 200 gastroscopic procedures and investigate the relationship between fasting time and feeling of subjects. The subjects will all receive examination between 10:30 to 11:30am. In the control group, the subjects are required to start the fast at 10:00pm the day before examination and can not drink water after 8:00am on the day of examination. In the test group, the subjects are required to have customized rice congee before 6:30am on the examination day and can not drink water after 8:00am. All subjects complete questionnaire which include discomfort and willingness to accept the same fasting regimen.
Surgical interventions are not only a physiological trauma, but also a psychological and social trauma because they cause deterioration of the individual's comfort. Comfort is among the most basic human needs and provides a better care output. One of the conditions that cause deterioration of comfort and anxiety in patients is hunger and thirst before surgery. Since 1994, several guides published by professional groups in many countries on pre-operative fasting periods have published that clear liquids can be taken up to 2 hours before the surgery in elective surgeries, and solid foods can be taken up to 6 hours before the surgery. One of the basic principles of ERAS protocols, which include evidence-based care interventions applied at all stages of the surgical process, for the preoperative period is to ensure that the patient takes a carbohydrate drink up to two hours before anesthesia and to shorten the long fasting period. In many countries, the problems experienced by patients as a result of long-term hunger have been identified. When the comfort status of the patients who were given carbohydrate-rich drinks before the surgery was examined, it was observed that the symptoms such as thirst, hunger, insufficiency, fatigue, nausea, pain, anxiety and depression were reduced and oral carbohydrate solutions were recommended. In the literature, it is stated that the prolongation of the fasting period causes an increase in the anxiety of the person and negatively affects his comfort, and it is recommended to drink 800 ml of carbohydrate liquid food until midnight the day before the surgery and 400 ml of liquid carbohydrate food 2-3 hours before the surgery in order to provide metabolic satiety. The nurse, who is one of the health workers responsible for the care of the patient, has to manage the restriction of oral food and liquid intake and the comfort of the patient in the best way before the operation. Accordingly, in our study, the answers were sought whether the oral carbohydrate solution given before hip arthroplasty had an effect on anxiety and patient comfort.
The aim of this trial is to investigate the effects of long-term fasting on size, mass, composition and function of metabolic active tissues in several organs that reexpand possibly rejuvenated after 1-4 months. Additionally, the lipid metabolism is investigated in depth.
Preoperative carbohydrate loading has been shown to reduce pre-operative discomfort and postoperative nausea and vomiting. There is no need for prolonged preoperative fasting of the patients, but the traditional approach still continues especially in thoracic surgery patients. For this purpose, we aimed to evaluate the effect of preoperative carbohydrate loading on postoperative morbidity in the patients.
This study aims to describe the dynamic changes in nutritional biomarkers in the blood during the postprandial period, i.e. the time period from the last meal and into the fasting state. In total 36 healthy, young men and women will be recruited in Bergen, Norway, and after receiving a standardized breakfast meal they will consume only water for the next 24 hours.
