摘要：

目的评价肺部三维立体虚拟解剖模型在重症医学部护士肺部超声培训中的应用效果。方法便利选取河南省某三级甲等医院重症医学部120名护士作为研究对象,采用随机数字表法分为试验组（n=60）和对照组（n=60）。试验组在对照组基础上,采用肺部三维立体虚拟解剖模型进行培训。通过3D医学影像可视化分析研究平台将肺部病变患者的CT数据转化为立体、虚拟的肺部解剖模型。培训导师佩戴增强现实眼镜将虚拟解剖模型与建模患者完全重合,按照改良床旁肺部超声评估方案,通过超声探头获取各筛查点的超声图像。护士通过显示屏观看在导师操作过程中的超声图像和相应虚拟解剖模型。比较两组理论考试成绩、操作技能成绩、操作耗时及对培训的满意度。结果试验组理论成绩及其中的肺部超声征象识别成绩、操作技能成绩及其中的扫描出“蝙蝠征”成绩、对培训的满意度评分均高于对照组（P<0.05）;试验组操作耗时少于对照组（P<0.05）。结论在培训中应用肺部三维立体虚拟解剖模型有助于护士对肺部超声图像和操作要求的理解,且护士的满意度较高。

Abstract:

Objective To explore the application effects of a three-dimensional virtual anatomical model in lung ultrasound training for nurses in the intensive care department. Methods A total of 120 nurses from the intensive care department in a tertiary hospital in Henan Province were randomly divided into the experimental group and the control group. Besides the training used in the control group,nurses in the experimental group were trained with a three-dimensional virtual anatomical model of lung. Through the 3D medical image visual analysis research platform,the CT data of patients with lung diseases were transformed into lung anatomical models which were three-dimensional and virtual. The mentors wore augmented reality glasses to completely overlap the virtual anatomical model with the modeled patient. According to the improved bedside lung ultrasonic evaluation scheme,the ultrasonic images of each screening point were obtained through the ultrasonic probe. The nurse watched the ultrasonic image and the corresponding virtual anatomical model during the mentor’s operation through the display screen. After the training,the theoretical and operational skills of the two groups of nurses were assessed,the operation time and the course satisfaction was also assessed. Results The theoretical scores,lung ultrasonic sign recognition scores,operation skill scores,bat sign scanning scores and training satisfaction scores of nurses in the experimental group were higher than those in the control group（P<0.05）. The operation time of nurses in the experimental group was shorter than that in the control group（P<0.05）. Conclusion The application of three-dimensional virtual anatomical model is helpful for nurses to understand the ultrasonic image and operation requirements of lung. Nurses are satisfied with the training highly.
