项目摘要

Background. Supraglottic airways (SGAs) are acknowledged as being reliable. However, several complications related to SGAs are still an issue. The aim of the current study was to compare the force exerted by the i-gel airway on a three-dimensional printed airway model with that exerted by a 3D printed modified SGA.Methods. After a preliminary experiment in Thiel embalmed cadavers, we created a 3D printed modified SGA (mSGA) and five 3D printed airway models based on computed tomography (CT) data from five female patients. We compared the force exerted by the i-gel and mSGA on the larynx in the 3D printed airway models. In addition, tidal volumes with insertion of the airway devices into the 3D printed airway model and administration of different levels of pressure controlled ventilation were compared.Results. The data below indicates median [min-max] for the i-gel and mSGA, respectively. The forces exerted by the cuff parts were as follows: ventral: 20.8 N [13.8-27.0] and 9.4 N [6.5-20.0], proximal: 1.3 N [0-5.0] and 2.0 N [0-5.0], and dorsal parts: 12.0 N [5.6-22.0] and 8.0 N [2.0-9.0], respectively. Hence, the force exerted by the ventral and dorsal parts of the mSGA cuff was significantly lower. We also found significantly higher tidal volumes with the mSGA under PCV of 10, 15, and 20 cmH2O.Conclusion. Our study indicated that the thinner and narrower mSGA cuff compared with the i-gel reduced the force exerted on a 3D printed airway model, and might lead to reduction of SGA-related complications without impairing ventilation.

背景资料。声门上呼吸道(SGA)被认为是可靠的。然而，与SGAS相关的几个并发症仍然是一个问题。本研究的目的是比较I-Gel气道对三维打印的气道模型和3D打印的改良的SGA施加的力。在Thiel防腐身体上进行了初步实验后，我们根据5名女性患者的CT数据创建了3D打印的改良SGA(MSGA)和5个3D打印的气道模型。我们比较了I-Gel和mSGA在3D打印的气道模型中对喉部的作用力。此外，还比较了在3D打印的气道模型中插入气道装置和实施不同水平的压力控制通气时的潮气量。下面的数据分别表示i-Gel和mSGA的中位数[min-max]。袖带部分的受力分别为腹侧20.8N[13.8~27.0]和9.4N[6.5~20.0]，近侧1.3N[0~5.0]和2.0N[0~5.0]，背侧12.0N[5.6~22.0]和8.0N[2.0~9.0]。因此，mSGA袖带的腹侧和背侧部分所施加的力明显较小。在PCV为10、15和20cmH2O时，mSGA的潮气量显著增加。我们的研究表明，与I-Gel相比，mSGA袖带更薄、更窄，减少了施加在3D打印气道模型上的力，并可能在不损害通气性的情况下减少SGA相关的并发症。
