Tracheal stenosis is the most common late airway complication of tracheostomy. Severe tracheal stenosis resulted in hemodynamic deterioration and impairment of respiratory system mechanics. We cared for an 86-year-old man with severe tracheal stenosis due to prolonged placement of a tracheostomy tube for 42-months. At the distal tip of the tracheostomy tube, bronchoscopy revealed severe tracheal luminal obstructions by granulation tissue. During pressure-controlled ventilation, the peak airway pressure was much higher than the inspiratory pressure. For patients with clinical signs of tracheal stenosis after tracheotomy, bronchoscopy should be done as early as possible.
气管狭窄是气管切开术后最常见的晚期气道并发症。严重的气管狭窄导致血流动力学恶化和呼吸系统力学受损。我们护理了一名86岁的男性患者，他因气管造口管放置长达42个月而出现严重的气管狭窄。在气管造口管的远端，支气管镜检查显示肉芽组织严重阻塞气管腔。在压力控制通气期间，气道峰值压力远高于吸气压力。对于气管切开术后有气管狭窄临床体征的患者，应尽早进行支气管镜检查。
