背景情况:

  • 外腔室排水 (EVD) 放置是一个关键的神经外科手术程序.
  • 手动EVD放置依赖于可变的解剖学地标,影响准确性.
  • 一个3D打印的培训模型提供了一种新的方法来增强EVD安置技能.

研究的目的:

  • 为了评估3D打印的EVD训练模型的有效性.
  • 评估标准化培训对EVD位置准确性的影响.
  • 为了测量神经外科医生培训后信心水平的变化.

主要方法:

  • 从患者的CT扫描中创建了具有不同心室大小的三维 (3D) 打印头部模型.
  • 25名神经外科医生接受了三轮培训方案 (预培训,神经导航培训,后培训).
  • 使用光学导航系统测量了EVD位置的准确性;通过问卷评估了信心.

主要成果:

  • 静脉内EVD安置的准确性从训练前的55.3%增加到训练后的84.0% (P < .001).
  • 训练后的理想入口和目标点的距离显著改善 (P < .001).
  • 对EVD安置和穿孔方向的信心显著增加,经验丰富的外科医生在培训后表现出与经验较少的外科医生相似的成功率.

结论:

  • 使用3D打印模型的标准化培训协议显著提高了神经外科EVD安置的准确性和信心.
  • 定期培训对于在EVD安置中保持高临床性能至关重要.
  • 对于复杂的病例,建议采用标准化程序和神经导航.
