OBJECTIVE American Society of Anesthesiology guidelines recommend preoperative fasts of 6 hours after light snacks and 8 hours after large meals. These guidelines were designed for healthy patients undergoing elective procedures but are often applied to intubated intensive care unit (ICU) patients. ICU patients undergoing routine procedures may be subjected to unnecessary prolonged fasts. This ...

BACKGROUND Preoperative fasting may lead to a fluid deficit of about 1 litre, which may contribute to perioperative discomfort and morbidity. We therefore examined the association between perioperatively administered fluids aiming to correct dehydration and clinical outcome. METHODS Review of randomized, controlled, clinical trials evaluating clinical outcome, in which fluid versus no fluid w...

background: today the use of laparoscopy before laparotomy is an effective method for decision-making in patients with gastric adenocarcinoma. the reliance on ct scans for decision-making purposes is not only unhelpful, yet also misleading . nonetheless, indications for laparoscopy and its application are changing daily. the low quality of diagnostic tools and epidemiological situation in our c...

This guideline aims to provide an overview of the present knowledge on aspects of perioperative fasting with assessment of the quality of the evidence. A systematic search was conducted in electronic databases to identify trials published between 1950 and late 2009 concerned with preoperative fasting, early resumption of oral intake and the effects of oral carbohydrate mixtures on gastric empty...

A study was carried out in which patients were asked questions to assess their knowledge of their condition and treatment, the questions relating particularly to care before siting an intravenous infusion and preoperative care. A high proportion of patients knew little about the procedure they were about to undergo. It is recommended that patients should be told more about matters relating to t...

As is detailed elsewhere in this issue, enhanced recovery pathways integrate evidence-based best practices across the spectrum of perioperative care. Although interventions in the operating room and in the postoperative ward are important for improving postoperative outcomes in enhanced recovery after surgery (ERAS®) pathways, an ERAS® approach for preoperative care is equally important for ach...

while fasting has been practiced for centuries, its beneficial effects was unknown until recently. this review tries to analyze the current literature of how fasting and intermittent fasting (if) could affect clinical pathological parameters, learning, mood and brain plasticity. the effects of different ways of fasting on metabolism and stress were also explored. animal experiments have elucida...

Background: Current researches associate long fasting periods to several adverse consequences. The fasting abbreviation to 2 h to clear liquids associated with the use of drinks containing carbohydrates attenuates endocrinometabolic response to surgical trauma, but often is observed children advised to not intake food from 00:00 h till the scheduled surgical time, regardless of what it is. Ai...

OBJECTIVE To determinate the predictive value of preoperative glucose test of diabetic patients, with age above 40 years, for visual acuity outcome and clinical perioperative complications, in cataract surgery with local anesthesia, in an academical medical center. METHODS Type 2 diabetic patients, above 40 years of age, indicated for cataract surgery between February 10, 2000 and January 10,...

Studies of the effects of preoperative starvation on blood glucose levels in children have produced apparently conflicting results. The study which we conducted, investigated the incidence of hypoglycaemia and hypoglycaemic signs in the children fasted for various periods. It also studied the hemodynamic responses in the perioperative period in relation to the duration of fasting and reliabilit...
