探讨骨折合并2型糖尿病患者术前营养状况指标对预后的影响。方法 123例接受手术治疗的2型糖尿病骨折患者按年龄分组后，对其术前血红蛋白、总蛋白、白蛋白、前白蛋白和淋巴细胞计数，以及总住院时间、术前准备时间、术后恢复时间、住院费用等指标进行分析。结果 中青年组的营养状况好于老年组；有营养风险的患者总住院时间及术前准备时间长于营养状况正常的患者；血糖控制良好者术前准备时间及术后并发症发生率低于控制不良者。结论 营养状况及血糖的控制情况关系到骨折合并2型糖尿病住院患者的预后，应采取个体化的营养支持，调整营养状态，以改善预后。

Objective To investigate the effect of preoperative indicators of changes in nutritional status on the clinical outcome of cases of fracture with type 2 diabetes.  Methods A retrospective analysis was conducted of 123 cases of type 2 diabetes fracture who received surgical treatment to find out about their preoperative hemoglobin, total protein, albumin, prealbumin, and lymphocyte count, the total length of stay, preoperative hospitalization time, postoperative hospital stay and hospitalization costs.Results Nutritional status of the young was better than that of the elders. The total length of stay, preoperative hospitalization time of normal nutrition status patients were better than abnormal. There was no significant difference in postoperative complications. The preoperative hospitalization time and postoperative complications of normal glucose control patients were better than those of the abnormal.  Conclusion Nutrition is related to the prognosis of fracture type 2 diabetes patients.
