Comparators of interest include, Carbohydrate- and protein-containing clear liquids alone and in combination. Although differences were not detected in thirst, preoperative nausea, or patient satisfaction, the body of evidence is consistent with lower patient ratings of hunger with carbohydrate-containing clear liquids over noncaloric ones. 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. This article is featured in This Month in Anesthesiology, page 1A. The members disclosed relevant relationships (industry and other entities) that might pose a conflict of interest. Smokeless tobacco products consist of tobacco that's chewed, sucked or sniffed, rather than smoked. Up to 400ml of clear liquids is considered an appropriate volume.
