Abstract：
OBJECTIVE: To test the effectiveness of a novel wire-guided scalpel (Guideblade) to create a precise dermatotomy incision for central venous catheter (CVC) insertion.
METHODS: Prospective, nonrandomized interventional study.
METHODS: Stanford University, single-center teaching hospital.
METHODS: Cardiac and vascular surgical patients (n = 100) with planned CVC insertion for operation.
METHODS: A wire-guided scalpel was used during CVC insertion.
RESULTS: A total of 188 CVCs were performed successfully with a wire-guided scalpel without the need for additional equipment in 100 patients, and 94% of CVCs were accomplished with only a single dermatotomy attempt. \"No bleeding\" or \"minimal bleeding\" at the insertion site was observed in 90% of patients 30 minutes after insertion and 80.7% at the conclusion of surgery.
CONCLUSIONS: The wire-guided scalpel was effective in performing dermatotomy for CVC with a 100% success rate and a very high first-attempt rate. The wire-guided scalpel may decrease bleeding at the CVC insertion site.

摘要：
目的：测试新型导线引导手术刀（Guideblar）的有效性，以创建用于中心静脉导管（CVC）插入的精确皮肤切开术切口。
方法：前瞻性，非随机干预研究。
方法：斯坦福大学，单中心教学医院。
方法：心脏和血管外科患者（n=100）计划插入CVC进行手术。
方法：在CVC插入过程中使用导丝引导手术刀。
结果：在不需要额外设备的情况下，在100例患者中，用钢丝引导的手术刀成功完成了188例CVC，94%的CVC仅通过一次皮肤切开术完成。90％的患者在插入后30分钟观察到插入部位的“无出血”或“最小出血”，在手术结束时观察到80.7％。
结论：导丝引导手术刀可有效进行CVC皮肤切开术，成功率为100％，首次尝试率很高。导线引导的手术刀可以减少CVC插入部位的出血。
