Studies have shown that patient education about the importance of preoperative fasting Patients ( N =105) aged 14 - 60 years, who were scheduled for elective surgery in the morning session (list starting time 07h00), were included in this prospective study. To a woman who has to accept caesarean section, preoperative fasting often is required. This is intended to prevent pulmonary aspiration of stomach contents during general anesthesia. According to the time of preoperative fasting, fasting conditions were divided into 5 groups: A, solid food ≥8 h and clear fluids ≥6 h; B, solid food ≥8 h and clear fluids ≥2 h < 6 h; C, solid food ≥6 h < 8 h and clear fluids < 2 h; D, solid food ≥2 h < 6 h and clear fluids < 2 h; E, solid food < 2 h and clear fluids < 2 h. Test of blood glucose level. There is consensus that solid food should be avoided for prolonged periods to allow clearance from the stomach (ie, six to eight hours or more), because aspiration of food particles can be immediately life threatening.

Prolonged preoperative fasting is one of the concerns of pediatricians and anesthesiologists in pediatric surgery. Conventional preoperative fasting time may aggravate insulin resistance and influence the elevation of glycemia , especially because it is frequently longer than the expected 6-8 h and may be as long as 10-16 h . Thus, NPO after midnight (Latin: Nulla per os; or "nothing by mouth") is a time-honored preoperative order. Background . Co-intervention with other oral substances in the four hours before surgery was of carbohydrate was at least 45g. This suggests that a 1‐h fasting time for water is entirely reasonable 20. Prolonged preoperative fasting times for healthy elective cases have been extrapolated from the aspiration risk of ‘full-stomach’ emergency cases. However, simply prolonging the fasting time does not necessarily produce the desired effect. However, long fasting prior to an elective operation is not only uncomfortable for the patient but has detrimental effects. Gastric emptying of liquids occurs very rapidly because they can pass immediately through the pylorus, whereas solids must first be digested to semi-fluid chyme. Effects of preoperative fasting on morbidity and gastric contents in patients undergoing day-stay surgery. Abola, Ramon E. MD; Gan, Tong J. MD, MHS, FRCA. Preoperative fasting is based on gastric physiology and expert opinion, as there is limited evidence that fasting improves outcomes. Evidence-Based Practice Project. The aim of this study was to assess the impact of preoperative fasting duration on blood glucose and hemodynamics in children. Gastric volume is a surrogate endpoint … De Aguilar-Nascimento, JE, Dock-Nascimento, DB 2010 Reducing preoperative fasting time: a trend based on evidence World Journal of Gastrointestinal Surgery 2 (3) 57 – 60 Google Scholar | Crossref | Medline.

Preoperative fasting is necessary to reduce the risk of regurgitation of gastric contents and pulmonary aspiration in patients undergoing general anaesthetic and procedural sedation. Fasting preoperative night-time “nothing by mouth”, often practiced, does not seem to be the best preparation option for candidates for elective surgery from the metabolic point of view and the patient’s own well-being. To systematically review the effect of different preoperative fasting regimens (duration, type and volume of permitted intake) on perioperative complications and patient wellbeing (including aspiration, regurgitation and related morbidity, thirst, hunger, pain, nausea, vomiting, anxiety) in different adult populations. it difficult coordinating preoperative fasting instruction with the schedule time. The importance of preoperative fasting was not explained for the vast proportion (94.2%) of patients and this probably affected adherence to the instruction. Preoperative Fasting Guidelines. Many methods have been used to assess gastric volume including nasogastric aspiration, isotope labelling, co‐absorption of paracetamol 19, magnetic resonance imaging (MRI) and ultrasound. Compared with the fasting for a long time (groups A and B: solid food > 8 h and clear fluids > 2 h at least), the incidence rate of hypoglycemia and acidosis of neonates in group C displayed a certain decrease (P < 0.05).

Time for anaesthetists to take back control of the preoperative fasting message. food and liquids within the prescribed time and the preoperative fasting intervention has been showed to ensure physiological stability and reduce the intraopera-tive and postoperative complications [8].

The great Sam Cooke once sang, “it’s been a long time coming… a change is gonna come.” The research and technology are here now. Preoperative fasting is intended to lower the amount of gastric contents in order to decrease the incidence of aspiration associated with endotracheal intubation. However, recent studies show that longer fasting time does not reduce aspiration associated complications. Less than full-time training A guide for training programme directors in anaesthesia and intensive care medicine . Of these, only ultrasound is of clinical utility.
