Airway Partial Obstruction by Internal Hermiation of Armored Endotracheal Tube: A case report: Mijeung Gwak, Hyun Sook Hwang, Eun Ha Suk, Pyung Hwan Park; Korean J Crit Care Med. 2002;17(1):29-33.

Abstract PDF: During general anesthesia, intubation with kink-resistant armored tubes permit the anesthesiologist to work some distance from the surgical field during operation on the head and neck or with patients whose unusual position may kink and obstruct a tube not so reinforced. But armored tubes are still subject to number of hazards, including herniation of the intra-luminal cuff or layer into the lumen of the tube. So extra care is required in their use. We report a case of intraluminal herniation of armored tube accompanied with peak inspiratory pressure during general anesthesia.

Airway Obstruction with Armored Tracheostomy Tube by Swelling of Inner Layer: A case report: Chang Young Jeong, Sang Hyun Kwak, Sung Su Chung, Hyon Jeong Lee, Tae Yob Kim; Korean J Crit Care Med. 1997;12(2):169-172.

Abstract PDF: One of the reasons for insertion of endotracheal tube is to provide a patent airway. Unfortunately, the tube itself may become the cause of airway obstruction. Especially, armored tube is known to be most effective in maintenance of airway patency. However, airway obstruction has been reported by a varity of causes even though armored tube was used. We experienced airway obstruction with armored tracheostomy tube by swelling of inner layer near the cuff. The tube was reused one and had been disinfected with ethylene oxide. Therefore, to prevent complication such as airway obstruction by use of armored tubes, it is desirable to avoid reusal of armored tube and to examine the lumen as well as cuff before intubation when reused.
