Application of NRS 2002 in nutritional screening of patients underwent thoracic surgery and study on nutritional nursing intervention

Objective: To explore application of Nutritional Risk Screening 2002 (NRS2002) scale in nutritional screening for thoracic surgery, and to analyze the nutritional nursing methods. Methods: Totally 98 patients with thoracic surgery in our hospital from March 2013 to March 2017 were randomly divided into control group and observation group, 49 cases in each group. The control group received routine nutrition nursing, the observation group evaluated by NRS 2002 scale were given specific nutritional nursing by regulating diets according to different nutritional status, until two groups were discharged from hospital. The conditions of nutritional risk were analyzed after 2 weeks of intervention, the changes of transferrin (TRF) and hemoglobin (Hb), prealbumin (PA), albumin (ALB) level and physical status were compared, the incidences of complications were compared. Results: The incidence of nutritional risk in the observation group was significantly lower than that of the control group (6.12% vs. 20.41%; χ2=4.346, P<0.05); there were significant differences in the ALB, PA, Hb, TRF of the observation group before and after intervention (P<0.05); the ALB, PA and TRF of the observation group after intervention were significantly higher than those of the control group (P<0.05); the upper arm muscle circumference, upper arm circumference and triceps skinfold thickness of two groups were higher than those before intervention, and the observation group after intervention were significantly higher than those of the control group (P<0.05); the hypoxemia and pulmonary infection in the observation group were significantly lower than those in the control group (4.08%, 2.04% vs. 16.33%, 12.24%; χ2=4.009, 4.405, P<0.05). Conclusion: NRS 2002 scale can identify the nutritional status of patients with open chest surgery and give targeted nursing guidance, it is worthy of clinical promotion.
