ASA members disagree and the consultants strongly disagree that proton pump inhibitors should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia in patients with no apparent increased risk for pulmonary aspiration. Multiple versus single pharmacologic agents. Although the task force does not recommend delaying surgery in healthy adults who have chewed gum during the fasting period, we urge clinicians to confirm the gum has been removed before anesthetic administration. Practice guidelines aim to improve patient care and patient outcomes by providing up-to-date information for patient care. 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.
