3D打印技术在快速治疗老年股骨转子间骨折医患沟通中的应用

目的　探讨3D打印技术在快速治疗老年股骨转子间骨折医患沟通中的应用效果。 方法　选取2018年7月~2019年4月本院老年髋部中心30例老年股骨转子间骨折拟行PFNA内固定手术治疗的患者。经签署知情同意书，利用随机数表将患者分成实验组和对照组，每组15例。实验组采用3D打印模型进行术前沟通，对照组采用常规术前沟通方法，分别进行术前医患沟通调查问卷信息采集，记录手术时机（入院到手术的间隔天数）、手术时间、出血量等，并进行统计分析。 结果　术前应用3D打印模型进行医患沟通，患者对病情、手术方案、护理等方面的理解有明显优势，患者满意度较高；实验组从入院到手术间隔时间明显较短，为（2.92±1.16）d，对照组（4.36±2.10）d，P<0.05。 结论　3D打印技术在快速治疗老年股骨转子间骨折医患沟通方面有显著效果，缩短术前间隔时间，提高患者满意度。

Application of 3D printing technology in doctor-patient communication for rapid treatment of intertrochanteric fracture of femur in elderly patients

Objective　To explore the clinical effects of 3D printing technology in the rapid treatment of intertrochanteric fracture in elderly patients.　Methods　Thirty patients treated with PFNA (Proximal Femoral Nail Antirotation) surgery were involved in our hospital from July 2018 to April 2019. After signing the informed consent, the patients were randomly divided into an experimental group and a control group, with 15 cases in each group. 3D printing technology was used to communicate before operation for the experimental group, while routine pre-operative communication method was used for the control group. After that, the information from the questionnaire of doctor-patient communication before and after operation were collected for the two groups. At the same time, the operation timing (days between admission and operation), operation time and bleeding volume were recorded and analyzed statistically.　Results　The application of 3D printing technology in the communication between doctors and patients before operation had obvious advantages in the understanding and recognition of patients' condition, operation program and nursing plan. Then patients' satisfaction was higher. At the same time, the experimental group also had better performance in operation timing (2.92±1.16) d, while the operation timing of the control group was (4.36±2.10) d (P<0.05).　Conclusions　3D printing technology has a significant effect on doctor-patient communication in the rapid treatment of intertrochanteric fracture of the femur in the elderly, which can shorten the preoperative interval and improve the patient satisfaction.
