Plstico Elstico, un programa de msica y canciones de Pacopepe Gil: Power Pop, Punk, Indie Pop, New Wave, Garage Table 7 summarizes the evidence for clinically important outcomes. Level 2: The literature contains multiple RCTs, but the number of RCTs is not sufficient to conduct a viable meta-analysis for the purpose of these updated guidelines. 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. A complete bibliography used to develop these updated guidelines, arranged alphabetically by author, is available as Supplemental Digital Content 1, http://links.lww.com/ALN/B340.

In adults, evidence comparing fasting with chewing gum was inconsistent with respect to patient-rated hunger92 or thirst92,93 (very low strength of evidence). Placebo-controlled RCTs are equivocal regarding the efficacy of glycopyrrolate to reduce gastric volume or acidity (Category A2-E evidence),83,102 and two nonrandomized placebo-controlled comparative studies report equivocal findings the efficacy of atropine on gastric volume and acidity (Category B1-E evidence).103,104.

Furthermore, it would be necessary to update related policies, printed literature, and wall posters/charts to ensure that patients are receiving consistent messages and instructions from all medical personnel. Throughout these guidelines, the term preoperative should be considered synonymous with preprocedural, as the latter term is often used to describe procedures that are not considered to be operations. For the previous update, an additional survey was sent to the consultants asking them to indicate which, if any, of the evidence linkages would change their clinical practices if the guidelines were instituted. Histamine-2 receptor antagonists: Meta-analysis of blinded placebo-controlled RCTs indicate that orally-administered ranitidine is effective in reducing gastric volume and acidity; the frequency of gastric volume > 25mL; the frequency of gastric pH levels < 2.5; and the risk of aspiration (i.e., gastric volume > 25mL and pH < 2.5) during the perioperative period (Category A1-B evidence).56,6170 Placebo-controlled RCTs of intravenous ranitidine report similar results for gastric pH (Category A2-B evidence) and equivocal findings for gastric volume (Category A2-E evidence).66,7174, Meta-analysis of placebo-controlled RCTs indicate that orally-administered cimetidine is effective in reducing gastric volume and acidity; the frequency of gastric volume > 25mL; the frequency of gastric pH levels < 2.5; and the risk of aspiration (i.e., gastric volume > 25mL and pH < 2.5) during the perioperative period (Category A1-B evidence).58,59,66,7587 Placebo-controlled RCTs of intravenous cimetidine report similar results for gastric pH (Category A2-B evidence), but equivocal findings for gastric volume (Category A2-E evidence).60,66,71,78,88. Category C: Informal Opinion.

Smokeless tobacco causes cancer of the mouth, esophagus, and pancreas. No aspiration was reported after either the fasting or carbohydrate-containing clear liquids groups in 31 randomized controlled trials,2326,29,30,32,33,36,37,39,4244,4764 2 nonrandomized trials,65,66 and 1 case-control study67 (strength of evidence not rated due to lack of events). All protein-containing clear liquids also contained carbohydrates. Mixed treatment comparisons did not support the superiority of complex carbohydrates over simple carbohydrates with respect to residual gastric volume or hunger (network meta-analysis; supplemental figs. Only 2 of the trials randomized participants into 1- and 2-h fasting protocols; the remaining studies were not designed to compare 1- and 2-h fasting; however, they included results from pediatric patients fasted less than 2h. Most children were ASA Physical Status I or II, although one trial enrolling patients with cyanotic congenital heart disease were more likely of higher ASA Physical Status (ASA Physical Status not reported). Smoking and gastric juice volume in outpatients. Third, expert consultants were asked to: (1) participate in opinion surveys on the effectiveness of various preoperative fasting strategies and pharmacologic agents and (2) review and comment on a draft of the guidelines developed by the Task Force. Both the consultants and ASA members disagree that gastrointestinal stimulants 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. Second, original published research studies from peer-reviewed journals relevant to preoperative fasting and pulmonary aspiration were reviewed and evaluated.

When an equal number of categorically distinct responses are obtained, the median value is determined by calculating the arithmetic mean of the two middle values. Gastric residual volume by magnetic ressonance after intake of maltodextrin and glutamine: A randomized double-blind, crossover study. These recommendations may be adopted, modified, or rejected according to clinical needs and constraints, and are not intended to replace local institutional policies. Trial comparator liquids such as water, placebo, broth, black tea, and black coffee are referred to as noncaloric clear liquids.. Premedication with cimetidine and metoclopramide.
