The two most common commercial percutaneous dilation tracheotomy (PDT) sets apply different techniques. Our aim was to investigate the biomechanical properties of these two techniques on an animal model, that simulate a human trachea.
Biomechanical properties of the different steps of the Ciaglia Blue Rhino® and Griggs Portex® techniques were measured on 20 pig cadavers.
We found that the use of the two different devices created equal sized openings in the trachea ( >0.05). The force needed to insert the Griggs forceps was 1.8 kg average compared to 2.51 kg using the Ciaglia dilator ( <0.00001). The calculated total energy expenditure in the Ciaglia Blue Rhino® kit was 1.46 times greater than the Griggs Portex® kit ( <0.0001). This was mainly due to the amount of energy required during the final dilator stage, which was 4 times more using the Ciaglia Blue Rhino® dilator than the Portex® Griggs-dilator forceps.
We conducted a series of biomechanical properties experiments on an animal model of PDT using two popular commercial kits - Griggs Portex® guidewire dilating forceps by Smiths Medical and Ciaglia Blue-Rhino® by Cook Medical. The Ciaglia technique required almost 50% more energy to perform a PDT ( <0.0001), mainly because of the force exerted during the final dilator insertion stage compared to the Griggs forceps. Further research is needed to examine if these properties are related to some of the PDT complications.

两种最常用的商用经皮扩张气管切开术（PDT）套件采用了不同的技术。我们的目的是在模拟人体气管的动物模型上研究这两种技术的生物力学特性。
在20头猪尸体上测量了Ciaglia Blue Rhino®和Griggs Portex®技术不同步骤的生物力学特性。
我们发现，使用两种不同的器械在气管中形成的开口大小相同（>0.05）。插入Griggs钳所需的平均力为1.8千克，而使用Ciaglia扩张器时为2.51千克（<0.00001）。计算得出，Ciaglia Blue Rhino®套件的总能量消耗比Griggs Portex®套件高1.46倍（<0.0001）。这主要是由于在最终扩张器阶段所需的能量，使用Ciaglia Blue Rhino®扩张器比使用Portex® Griggs扩张钳多4倍。
我们使用两种常用的商用套件——史密斯医疗公司生产的Griggs Portex®导丝扩张钳和库克医疗公司生产的Ciaglia Blue-Rhino®，在PDT动物模型上进行了一系列生物力学特性实验。Ciaglia技术进行PDT所需的能量几乎多50%（<0.0001），主要是因为与Griggs钳相比，在最终扩张器插入阶段施加的力更大。是否这些特性与某些PDT并发症有关，还需要进一步研究。
