Fasting duration is often substantially longer than recommended irrespective of a 1- or 2-h clear liquid fasting policy.107112 Prolonged fasting influences patient-related outcomes (preoperative thirst, hunger, anxiety, nausea and vomiting, pain, and reduced feeling of well-being) and clinical outcomes (dehydration, electrolyte imbalance, and hypotension at induction of general anesthesia).113,114 Due to low-quality evidence, the task force was unable to make a recommendation for reducing the clear liquid fasting duration to 1h in the pediatric population.

Compared with water, residual gastric volume increased in patients chewing gum (very low strength of evidence) in one crossover study.98. Conditional recommendations are those where most, but not all, would choose the action or approach.20,21 When the task force judged the body of evidence inappropriate to rate the strength of evidence but judged a recommendation important, a best practice statement was considered.22. For example, a rapid-sequence induction/endotracheal intubation technique or awake endotracheal intubation technique may be useful to prevent this problem during the delivery of anesthesia care. Black or white coffee before anaesthesia? Supplemental tables 1 to 4 (https://links.lww.com/ALN/C934) detail the strength-of-evidence ratings.

The history, examination, and interview should include assessment of ASA physical status, age, sex, type of surgery, and potential for difficult airway management as well as consideration of gastroesophageal reflux disease,* dysphagia symptoms, other gastrointestinal motility and metabolic disorders (e.g., diabetes mellitus) that may increase the risk of regurgitation and pulmonary aspiration. 1 Clear liquids include water, tea, black coffee, pulp-free juice, and carbohydrate-rich drinks.

The literature relating to seven evidence linkages contained enough studies with well-defined experimental designs and statistical information to conduct formal meta-analyses. Preoperative oral carbohydrate treatment attenuates immediate postoperative insulin resistance. Inadequate literature cannot be used to assess relationships among clinical interventions and outcomes because a clear interpretation of findings is not obtained due to methodological concerns (e.g., confounding of study design or implementation) or the study does not meet the criteria for content as defined in the Focus of the guidelines. chewing tobacco | Student Doctor Network Oral rehydration with 10% carbohydrate drink for preventing postoperative nausea and vomiting (PONV) after low dose of spinal morphine.
