目的:比较老年与中青年外科住院患者入院及出院时的营养状况,判断营养支持合理性。方法:应用NRS2002方法,对南京医科大学第一附属医院167例新入院患者进行调查,以65岁为界将患者分为中青年组和老年组,NRS≥3分为有营养风险,调查住院期间营养支持方式以及预后。结果:1老年患者出院及入院时NRS评分、NRS≥3分患者所占比例均高于中青年患者,两组出院时的营养状况均较入院时差;2中青年组和老年组分别有23例(20%)和12例(22%)获得肠外营养(PN)支持,完全肠外营养(TPN)提供的能量低于机体需要量,能量支持不足比例达60%和67%,热氮比偏低;而在NRS≥3分的患者中,两组分别有12例(24%)和11例(34%)患者获得PN,TPN支持提供的能量不能达到目标能量供给,能量支持不足比例达63%和73%,热氮比亦偏低;3NRS≥3分的患者中老年组与中青年组NRS≥3分的患者相比,住院天数更长。结论:应加强老年患者住院期间的营养支持治疗;应根据NRS评分对有营养风险的患者给予营养支持;TPN提供的能量不能达到目标能量供给,且成分不合理;在PN中,仍存在单氨基酸输注。
OBJECTIVE: To compare the nutritional status of hospitalized and discharged patients in elderly and middle-aged surgical inpatients to determine the nutritional support rationality. Methods: NRS2002 method was used to investigate the 167 newly admitted patients in the First Affiliated Hospital of Nanjing Medical University. Patients aged 65 years were divided into middle-aged and young patients. The NRS≥3 was classified as having nutritional risk. During the hospitalization period Nutritional support and prognosis. Results: 1 Elderly patients discharged at admission and NRS score, NRS≥3 points patients were higher than the proportion of young patients, the nutritional status of the two groups were discharged from the hospital admission time difference; 2 young group and the elderly group were 23 cases Total parenteral nutrition (TPN) provided less energy than required by the body with energy support deficits of 60% and 67%, respectively, with a ratio of heat to nitrogen (PN) of 12 (22% While in patients with NRS≥3, 12 patients (24%) and 11 patients (34%) in both groups received PN. The energy provided by TPN support can not reach the target energy supply, and the energy insufficiency ratio reached 63% and 73% respectively, and the ratio of heat to nitrogen was also low. Patients with 3NRS≥3 had longer days of hospitalization than those with middle-aged and younger patients with NRS≥3. CONCLUSIONS: Nutritional supportive care should be strengthened for elderly patients during hospitalization. Nutritional support should be provided to patients at nutritional risk based on the NRS score. The energy provided by the TPN does not reach the target energy supply and the composition is unreasonable. In PN, there is still a single amino acid Infusion.
