目的 分析添加鱼油的肠外营养在胃肠肿瘤术后患者中的应用效果。方法 选取接受手术治疗的60例胃肠肿瘤术后患者随机分为观察组（30例,添加鱼油的肠外营养）和对照组（30例,常规肠外营养）,对比两组效果。结果 经干预,两组血清TP、ALB、PA、TF含量提高（P<0.05）,且观察组含量显著高于对照组（P<0.05）;两组血清IL-6、CRP含量,并发症发生率降低（P<0.05）,观察组降低更显著（P<0.05）。结论 添加鱼油的肠外营养可更好地为胃肠肿瘤术后患者提供营养支持,降低术后炎性反应及并发症,值得推广。

Objective To investigate the effect of parenteral nutrition with fish oil on patients after gastrointestinal tumor surgery. Methods Sixty patients after gastrointestinal tumor surgery were randomly divided into an observation group (n=30, who received parenteral nutrition with fish oil) and a control group (n=30, who received conventional parenteral nutrition). The effects of the two groups were compared. Results After designed intervention, serum TP, ALB, PA, and TF in both groups were elevated, and the levels in the observation group were significantly higher than those in the control group (P<0.05); serum IL-6 and CRP and the incidence rate of complications in both groups were decreased, and the declines were steeper in the observation group than those in the control group (P<0.05). Conclusion Parenteral nutrition with fish oil not only provides better nutritional support for patients after gastrointestinal tumor surgery, but also reduces postoperative inflammatory reaction and complications, which is worthy of clinical promotion.
