[摘要] 目的 探讨口服营养补充(ONS)对老年慢性阻塞性肺疾病(COPD)稳定期出院患者营养状态和肺功能的影响。方法 将85例老年COPD稳定期出院患者随机分为对照组和ONS组。对照组给予常规的饮食指导,ONS组在饮食指导的基础上每日增加口服摄入450 kcal的整蛋白肠内营养制剂,持续1个月。观察两组患者出院当天和出院后90 d的NRS-2002评分、体质量指数(BMI)、血清白蛋白等营养相关指标及肺功能的变化。 结果 出院当天两组患者患有营养风险(NRS-2002≥3)的比例相当(P>0.05),同时两组间BMI、血清白蛋白等营养相关指标及呼吸功能亦无明显差异(P>0.05)。出院后通过口服营养补充,与对照组相比,ONS组患有营养风险的比例明显降低,BMI明显增加,血清白蛋白和前白蛋白浓度明显升高,差异具有统计学意义(P<0.05);同時,ONS组的肺功能较对照组明显改善,差异具有统计学意义(P<0.05)。 结论 ONS可改善老年COPD稳定期出院患者的营养状态,增强机体的肺功能。

[Abstract] Objective To investigate the influence of oral nutrition supplement(ONS) on the nutritional status and lung function of elder discharged patients with stable chronic obstructive pulmonary disease(COPD). Methods 85 elder discharged patients with stable COPD were randomized into control group and ONS group. Patients in control group received routine diet direction. Patients in ONS group received additional oral administration of whole protein enteral nutrition prepations for 450 kcal per day and lasted 1 month. The nutrition-related indicators of NRS-2002 score in the day patients were discharged and 90 days thereafter, body mass index(BMI) and serum albumin as well as the changes of lung function were observed. Results The proportions of patients with nutritional risk(NRS-2002≥3) in the day patients were discharged in two groups were similar(P>0.05). There was no significant difference in BMI, serum albumin and lung function between two groups(P>0.05). Through ONS after discharge, compared with control group, the proportion of patients with nutrition risk decreased significantly as well as the BMI and the levels of serum albumin and prealbumin increased significantly(P<0.05). In the meantime, lung function in ONS group improved statistically(P<0.05). Conclusion ONS could improve the nutritional status and lung function of elder discharged patients with stable COPD.

慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)是一种气流受限不完全可逆,并呈进行性加重的慢性肺部疾病[1]。据统计,COPD目前是全球第4大死亡原因,至2020年,COPD将成为全球死亡原因的第3位,位居全球经济负担第5位[2,3]。COPD已成为重要的社会公共卫生问题[4]。如何维护COPD患者肺功能并防治并发症的发生,已成为内科关注的焦点[5]。研究表明,COPD人群营养不良或营养风险的发生率较高,营养不良是COPD患者急性加重、感染、死亡等并发症的重要原因,特别是老年COPD患者营养不良的发生率更高[6-8]。口服营养补充(oral nutritional supplement,ONS)是以增加口服营养摄入为目的,能够给机体提供多种宏量营养素和微量营养素,是一种有效的营养支持方式,目前已成为肠内营养支持的首选[9-12]。然而……
