摘要目的了解胸外科择期手术肿瘤患者术前营养状况，为临床掌握营养支持的合理时机和实施个体化的营养支持方案提供依据。方法采用患者主观营养评估问卷（ PG-SGA ）对2013年6—11月接受择期手术治疗的胸外科肿瘤患者88例术前营养状况进行评估。结果88例胸外科肿瘤患者PG-SGA营养状况评价总体得分P50为8分；无需营养干预者仅占14．8％，需医护人员行药物治疗指导者占12．5％，需营养支持治疗者占26．1％，而急需实施营养干预或改善症状的治疗者占46．6％。食管癌患者营养不良程度高于肺胸部肿瘤患者，差异有统计学意义（χ2＝－3．62，P＜0．01）。结论推广应用肿瘤患者营养评估专用工具PG-SGA对胸外科住院患者进行评价，根据营养风险情况进行营养指导，实施早期营养治疗，可取得最佳营养干预结果。

abstractsObjective To understand the preoperative nutrition status of neoplasms patients in the department of thoracic surgery, in order to provide the basis for mastering the appropriate time of nutritional support and the implementation of individualized nutritional support scheme.Methods Eighty-eight neoplasms patients in the department of thoracic surgery from June 2013 to November 2013 were chosen, and the preoperative nutrition status of patients was evaluated by the scored patient-generated subjective global assessment (PG-SGA).Results The P50 score of PG-SGA was 8.The percent of patients who don’ t need nutritional intervention was 14.8%, and the percent of patients who needed medication guide was 12.5%, and the percent of patients who need nutrition support was 26.1%, and the percent of patients who were in great demand of nutrition intervention was 46.6%.The degree of malnutrition in the esophageal cancer patients was higher than that in the lung/thoracic cancer patients, and the difference was statistically significant (χ2 =-3.62,P <0.01). Conclusions Application of PG-SGA can assess the preoperative nutrition status of neoplasms patients in the department of thoracic surgery, and is worthy of clinical promotion.The nutrition guidance should be carried out according to the risk of nutrition, and the early nutrition treatment should be implemented so as to get the best nutrition intervention.
