Title:SURGERY NURSES' KNOWLEDGE AND PRACTICE ABOUT PREOPERATIVE FASTING Title:SURGERY NURSES' KNOWLEDGE AND PRACTICE ABOUT PREOPERATIVE FASTING  A surgical initiative is an important life experience that creates stress on the individual. In the pre-operative period, the preparation of the individual in a physical, psychological and legal way is of great importance. One of the applications included in the framework of pre-operative physiological preparation is the limitation of the patient's oral intake of nutrients and fluids.  Despite the abundance of evidence on the negative aspects of leaving patients hungry after midnight, this application is continued to be routine in many hospitals. This research was carried out with the aim of evaluating the practices and level of knowledge of nurses regarding pre-operative hunger that is being implemented in a university hospital.   means and methods. The universe of research was formed by nurses working in the surgical units of a university hospital. The aim was to reach the entire universe (250) and the sample of the research was made by 56% (140) nurses. For the conduct of the research, a written permission was obtained from the Ethics Board of the University of Ege Nursing Faculty, the hospital where the research was carried out and the nurses to participate in the research. The data was collected between 15 January and 15 March 2014. The data was obtained by the "Nursing Information Form". The findings and the result. The study found that the average age of nurses is 36.94 (min:23 max:56), 130 (%92.9) women, 111 (%79.3) graduates, and the average year of work as nurses is 14.87 (min:1, max:33) years.  All the nurses who participated in the study said that in the clinics where they worked, they were routine pre-operative patients with fluid/food restrictions after 24:00 in the night. The study found that 88.6 percent of the nurses involved did not read scientific publications on nutrient/fluid restrictions. The study found that the nurses who participated in the study were unknown of evidence-based guidelines on the limitation of nutrients/fluids and they applied the traditional approach. To reflect evidence-based practices related to pre-operative hunger in the clinical area, it is recommended that the applicability in the clinic is reviewed by the surgical team by reviewing the protocols related to pre-operative hunger.  Abstract of: Aim. Surgical intervention is an important life experience that creates stress on the individual. Physical, psychological and legal preparation of the individual is of great importance in the preoperative period. One of the applications in preoperative period physiological preparations is the restriction of oral intake of nutrients and fluids for the patient. There were many evidence about the hunger patient during the night before the operation was not necessary but this procedure was going on in many centers. This study was carried out to evaluate nurses knowledge and practice preoperative fasting in a university hospital. Materials and Methods. The research population consisted of nurses who work in surgical units a University Hospital. The objective was to reach the entire universe (250), but the sample of the research consisted of 56% (140) nurses. Written permission was taken from the Ege University Faculty of Nursing Ethics Committee, the Ege University Medical Faculty Hospital Administration and nurses. Data were collected between the dates of 15 January - 15 April 2014. The data for this research was collected by Nurse Information Form. Results and Conclusions.   It was determined that the nurses assigned to research were the average age was 36.94 (min:23 max:56), 92. 9% (130) of them were female, 79.3% (111) of them were graduate degree, were an average of 14.87 years working as a nurse (min:1, max:33). All of the nurses participating in the study stated that the clinics routinely performed liquid / nutrient restriction after midnight on the day of surgery. It was determined that the nurses assigned to research 88.6% did not read scientific publications about nutrient / fluid restriction. Nurses participating in the study were found not to be aware of the evidence-based guidelines for nutrient/fluid restriction and to apply the traditional approach. It is suggested to review the protocols related to preoperative fasting and to make clinical feasibility with the surgical team for the reflection of clinically relevant evidence-based practices on preoperative fasting.
