择期手术糖尿病患者的胰岛素认知调查

目的调查口服药治疗中的2型糖尿病患者对胰岛素的认知状况。方法择期手术的糖尿病患者230人，通过问卷确定胰岛素认知偏差组124人；认知相对客观的对照组106人。结果偏差组占54％，其中的女性、高龄、低教育程度和居住在农村的比例高于对照组，曾经应用过胰岛素的比例低于对照组。偏差组的平均糖化血红蛋白高于对照组，术前血糖准备时间长于对照组，发生低血糖比例的差异无统计学意义。结论口服药物治疗中的糖尿病患者仍有54％的人存在胰岛素认知偏差；他们的血糖控制较差，术前血糖准备的时间较长。

The Survey of Insulin Cognition of Patients with Type 2 Diabetes Mellitus Waiting for Selective Operations

Objective To investigate the insulin cognition of patients with type 2 diabetes mellitus （T2DM） waiting for selective operations. Methods A total of 230 inpatients with type 2 diabetes mellitus were investigated, including 124 patients with improper insulin cognition （Group Improper Cognition, GIC） and 106 patients with proper insulin cognition （Group Proper Cognition, GPC） as control. Results 54% inpatients with type 2 diabetes mellitus treated with oral antidiabetic drugs （OAD） had improper insulin cognition. GIC had higher HbAmc% （8.26±1.56 vs 7.68±1.55, P=0.005）, more time of preoperative preparation [（4.74±1.29） days vs （3.87±1.25） days, P=0.000], higher proportions of female [（85/124） vs （57/106）, P=0.031], aged patients [（70/124） vs （45/106）, P=-0.047], lower educational level [（41/124） vs （20/106）, P=-0.023], rural inhabitant [（55/124） vs （31/106）, P=0.026] and less previous insulin application [（21/124） vs （36/106）, P=-0.005] than those of GPC. T2DM family history [（31/124） vs （34/106）, P=-0.298] and hypoglycemia occurrence [（18/124） vs （7/106）, P=0.087] were not statistically significant between the two groups. Conelmions There were still 54% inpatients with type 2 diabetes mellitus treated with OAD having improper insulin cognition. They were of bad blood glucose control and needed more time to control blood glucose treated with insulin for preoperative preparation.
