Because of difficult weaning from mechanical ventilation, a 59-yr-old man admitted for emergency cardiac surgery underwent a bedside PercuTwist tracheostomy on day 14 of his intensive care unit stay. We observed a double fracture of the second tracheal ring during the initial dilation process with the PercuTwist dilator, associated with distal migration of a cartilage fragment, which was avulsed from the anterior portion of the second cartilaginous ring.
Like other antegrade single-step techniques, the PercuTwist tracheostomy presents the risk of anterior tracheal wall damage during the initial stage of the dilation process. Antegrade forces applied to the trachea should be minimized by sufficiently deep skin incision and both slow and smooth initial rotation of the dilator.
由于机械通气撤机困难,一名因急诊心脏手术入院的59岁男性在重症监护病房住院第14天接受了床边经皮旋转气管切开术。在使用经皮旋转扩张器进行初始扩张过程中,我们观察到第二气管环双骨折,伴有软骨碎片向远端移位,该碎片从第二软骨环前部撕脱。
与其他顺行单步技术一样,经皮旋转气管切开术在扩张过程初始阶段存在气管前壁损伤风险。应通过足够深的皮肤切口以及扩张器缓慢、平稳的初始旋转,将施加于气管的顺行力量降至最低。
