Abstract
Background and aim:
The repairing effect of glucose on brain cognition functioning, especiallyattention 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.
Materials and Methods:
A quasi-experimental study was carried out. A convenience sample of 60nurses 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
PQ 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.
Findings:
The results indicated that glucose consumption improved the attention accuracy of nurses(P<0.001).
Conclusion
: Based on the results, glucose consumption or carbohydrate diet in night work nursingeffects on brain cognition performance especially accuracy.
