目的 观察粗盐热疗法对老年2型糖尿病患者胰岛素注射致皮下硬结的效果。方法前期动态观察自制粗盐包经微波炉不同火力加热2 min后温度的变化情况,选用适宜温度。对纳入研究的34例老年2型糖尿病胰岛素注射致皮下硬结患者,在常规教育指导的基础上,采用粗盐包热敷于皮下硬结处,干预2周,比较干预前后患者硬结的直径大小,评价有效率,评价患者粗盐热疗的舒适度。结果 干预后,患者皮下硬结直径（5.36±4.17） mm,小于干预前的（12.78±4.21） mm,差异有统计学意义（t=1.682,P=0.006）;有效率为88.2%（30/34）;患者粗盐热疗过程中感觉舒适者32例（94.1%）,轻度不舒适者2例（5.9%）。结论 采用粗盐热敷包进行局部热疗,取材方便,操作简单,患者舒适,能较好地促进老年2型糖尿病患者胰岛素注射所致的皮下硬结消散。

Objective To observe the effects of crude salt thermotherapy on lipohypertrophy caused by insulin injection in elderly patients with type 2 diabetes.Methods The change of temperature of self-made crude salt package heated by microwave oven for 2 minutes was observed dynamically at first and the appropriate temperature was selected based on the initial observation. The lipohypertrophy caused by insulin injection in 34 elderly patients with type 2 diabetes was identified in the study. On the basis of routine diabetes health education,crude salt thermotherapy was used to alleviate the severity of lipohypertrophy. The duration of the intervention lasted for 2 weeks. The diameter of patient’s lipohypertrophy was measured and analyzed before and after the intervention. Besides,patients’ comfor-table level was also assessed.Results After the thermotherapy,the diameter of lipohypertrophy was（12.78±4.21） mm,which was significantly smaller than that of（5.36±4.17） mm before the intervention（P<0.01）. The total effective rates was 88.2%（30/34）. During the procedure,94.1% of the subjects reported the process of thermotherapy was comfortable while discomfort experience was also received from 5.9% participants.Conclusion The crude salt thermotherapy is convenient and easy. It can improve patients’,comfortable experience and alleviate the size of lipohypertrophy caused by insulin injection in elderly patients with type 2 diabetes.
