To report a novel technique ("paper rail") to facilitate inserting the tail of a microguidewire into the tip of a low-profile device during endovascular procedures.
A sterilized nonwoven fabric tape with a smooth glossy paper backing is used. The tape has several linear folds ideal for a paper rail. Holding each piece of equipment about 5 cm from its respective tip, both the tail of the guidewire and the tip of the catheter are navigated at a 30° angle toward each other in the crease until the guidewire enters the catheter. The paper rail technique was compared with the conventional freehand method under varying luminosities found in an operating room. The paper rail technique was most effective in suboptimal lighting, where the mean time was reduced from 83 seconds with the conventional method to 20 seconds with the paper rail maneuver. The times required to insert the wire with the paper rail method were comparable (~22 seconds) at all light levels.
The paper rail method may help improve the speed and accurate insertion of the tail of a microguidewire into the tip of low-profile devices during endovascular procedures. It may be particularly useful for physicians in a low-light environment or trainees.
报告一种新的技术（“纸轨”），以方便在血管内手术中将微导丝的尾部插入小口径器械的尖端。
使用带有光滑光泽纸衬背的消毒无纺胶带。该胶带具有几条理想的线性折叠，适合用作纸轨。将每种设备的末端保持在离各自尖端约 5 厘米的位置，将导丝的尾部和导管的尖端以 30°角向彼此的折痕处导航，直到导丝进入导管。在手术室中不同亮度下，将纸轨技术与传统的徒手方法进行比较。在照明条件不佳的情况下，纸轨技术最为有效，使用传统方法的平均时间从 83 秒减少到使用纸轨操作的 20 秒。使用纸轨方法插入导丝所需的时间在所有光照水平下都相当（~22 秒）。
纸轨方法可能有助于提高血管内手术中将微导丝的尾部准确插入小口径器械尖端的速度。对于低光照环境中的医生或培训医师来说，它可能特别有用。
