早期喉癌部分切除常采用一次性导尿管当喉模代替,但术后拔出时由于一次性气囊导管壁过薄,易因破损漏水或体位不当等原因,造成气管切开处拔除喉膜时引起阻塞气道,发生窒息,危及生命,我们在喉癌部分切除术中采用扩张子既能防止喉狭窄,防止声带粘连,还可以压迫止血,避免因注入过多水导致管壁破裂,体位等风险。现介绍如下。1材料与方法1.1材料与制作1副无菌手套,凡士林纱条,7#幕丝线,9*28 Partial laryngeal resection of the early use of disposable catheters when the laryngeal model instead, but after the pull-out because of the one-time balloon catheter wall is too thin, easy to damage due to leakage or improper position and other reasons, resulting in tracheotomy removal of laryngeal When blocking the airway, suffocation, life-threatening, we use partial dilation laryngeal surgery to prevent the expansion of the larynx can prevent stenosis, prevent vocal cord adhesion, but also oppression hemostasis, to avoid excessive water injection led to the rupture of the wall, body position Other risks. Now introduced as follows. 1 Materials and Methods 1.1 Materials and Production 1 sterile gloves, Vaseline gauze, 7 # curtain thread, 9 * 28
