ABSTRACT
The repairing effect of glucose on brain cognition functioning, especially attention has been studied widely.Cognitive performance and attention is a vital aspect in nursing practice. Decreased attention and nursing errors may result in substantial mortality, morbidity, and additional health care costs. The aim of this study was to determine the effect of the blood glucose concentration on night work nurses' attention accuracy in military hospitals in Tehran, Iran. A quasi-experimental study was carried out. A convenience sample of 60 nurses working in, two military hospitals in Tehran participated in the study. These nurses were randomly allocated in intervention and control groups. The study was carried out from Sep2009 to April 2010. Data were collected using a demographic data form and attention accuracy was evaluated by Toulouse- Pieron and Bonnardel test. Data collection and intervention was carried out during 4 to 5 am. The blood glucose concentration was measured before intervention, then nurses in intervention group received gr glucose solution, and nurses in control group drank water. One hour after intervention attention accuracy and blood glucose reevaluated in both groups. Data were analyzed by SPSS V. 15 software. The results indicated that glucose consumption improved the attention accuracy of nurses [P<0.001]. Based on the results, glucose consumption or carbohydrate diet in night work nursing effects on brain cognition performance especially accuracy
