Monopolar electrosurgery is the gold standard for surgical preparation in thoracoscopic spine procedures. However, use of ultrasound scissors could decrease blood loss, accelerate the preparation time and improve patient safety, while minimizing operative costs. This trial compares both preparation techniques for ventral thoracoscopic spondylodesis.
The study design is an open, prospective, randomized, and double-blinded two-armed clinical trial performed in two centres. Forty-one patients with vertebral body fractures from T10 to L2 were included. Primary endpoint: preparation time. Secondary endpoints: blood loss, organ injuries, duration of hospitalization.
Primary and secondary endpoints did not differ significantly between groups (p level 0.05). Increased blood loss (150 ml or more) was eliminated with ultrasound scissors (p = 0.0014).
Primary and secondary endpoints did not differ significantly between the two preparation techniques. The use of either ultrasound scissors or electric scalpel offers safe and effective preparation for thoracoscopic spine surgery.
单极电外科手术是胸腔镜脊柱手术中手术准备的金标准。然而，使用超声刀可能会减少失血、加快准备时间并提高患者安全性，同时将手术成本降至最低。本试验比较了两种用于前路胸腔镜脊柱融合术的准备技术。
本研究设计为一项在两个中心进行的开放性、前瞻性、随机双盲双臂临床试验。纳入了41例T10至L2椎体骨折患者。主要终点：准备时间。次要终点：失血量、器官损伤、住院时间。
两组之间的主要和次要终点无显著差异（p值0.05）。超声刀消除了失血量增加（150毫升或更多）的情况（p = 0.0014）。
两种准备技术之间的主要和次要终点无显著差异。使用超声刀或电刀为胸腔镜脊柱手术提供了安全有效的准备。
