Aerothermotherapy with a Leister hot air coagulator was tested in a simulated operation field followed by a prospective double-blind animal pilot study to examine hemostasis and tissue reactions. Two symmetrical incisions were made on the back of 5 rabbits. One of the two wounds was randomised to aerothermotherapy. The temperature rise in the wound was registered by thermistors. No wound complications were observed. Five days postoperatively all wounds were excised for histological examination. A superficial muscular cell necrosis was observed in 3 of the 5 hot-air-coagulated back wounds. Liver resection was performed in 2 of the rabbits. The bleeding from the resection surface was stopped effectively by aerothermotherapy. Combination of the hot air temperature, the distance to the tissue and the application time was crucial for avoiding burns. If these factors are observed, the hot air coagulator may be used as a supplement to conventional methods of hemostasis.
使用莱斯特热空气凝固器进行空气热疗法,首先在模拟手术区域进行测试,然后进行前瞻性双盲动物初步研究,以检查止血效果和组织反应。在5只兔子的背部制作两个对称切口。两个伤口中的一个随机接受空气热疗法。伤口温度上升由热敏电阻记录。未观察到伤口并发症。术后5天,切除所有伤口进行组织学检查。在5个热空气凝固的背部伤口中,有3个观察到浅表肌细胞坏死。对2只兔子进行了肝切除术。空气热疗法有效止住了切除表面的出血。热空气温度、与组织的距离和应用时间的组合对于避免烧伤至关重要。如果注意到这些因素,热空气凝固器可作为传统止血方法的补充。
