Reinforced endotracheal tubes (ET) are advantageous in preventing tube obstruction and kinking by procedural compression during neurosurgeries. However, the standard reinforced ET contains an embedded stainless steel (SS) helical wire, which produces artifacts and heat during magnetic resonance imaging (MRI). Therefore, MRI is not indicated in the presence of a reinforced ET containing SS. To overcome this challenge, we developed an MRI-compatible titanium (Ti) reinforced ET. A newly developed Ti alloy helical wire was inserted in a reinforced ET. Here, we report our first clinical experience with six patients who underwent neurosurgery intubated with this Ti-alloy-reinforced ET. The Ti-alloy-reinforced ET was used in six patients requiring reinforced ET intubation. It was clearly delineated on radiography, and metal artifacts were small on computed tomography. Patients intubated with the Ti-alloy-reinforced ET could safely undergo MRI under sedation. MR images without remarkable susceptibility artifacts were obtained without noted adverse effects. We invented a novel Ti-alloy-reinforced ET. This device allows clinical use during MRI because it is less susceptible to artifacts in high magnetic fields.
加强型气管插管（ET）在预防神经外科手术过程中因操作压迫导致的导管阻塞和扭结方面具有优势。然而，标准的加强型ET包含一根嵌入式不锈钢（SS）螺旋丝，在磁共振成像（MRI）期间会产生伪影和热量。因此，存在含SS的加强型ET时不建议进行MRI检查。为了克服这一挑战，我们开发了一种与MRI兼容的钛（Ti）加强型ET。将一种新开发的钛合金螺旋丝插入加强型ET中。在此，我们报告了6例使用这种钛合金加强型ET进行神经外科手术插管患者的首次临床经验。钛合金加强型ET用于6例需要加强型ET插管的患者。在X线片上清晰可见，在计算机断层扫描上金属伪影较小。使用钛合金加强型ET插管的患者在镇静下可安全地接受MRI检查。获得了没有明显磁敏感伪影的MR图像，且未观察到不良反应。我们发明了一种新型钛合金加强型ET。该装置在MRI检查期间可用于临床，因为它在高磁场中不易产生伪影。
