Steps necessary are the identification of the key concepts/phrases to search such as "fasting in the preoperative period" and "ASA guidelines in the preoperative period." After the right key search, proper search strategy of related literature will be made in electronic databases, conference proceedings, and reference lists from relevant articles in the preoperative fasting. Literature must include findings during medical practice in the 90’s and year 2000 and up to determine advances made in the practice of perioperative fasting and to analyze the outcome of both traditional and ASA preoperative fasting guidelines. Google Scholar, PubMed, Medline, and Wiley Online Library contain electronic sources with an array of related journals, studies, and literature that can support the study also with evidence-based nursing practice.
