摘要

全喉切除术(TLE)导致呼吸道和消化道的永久分离,要求所有气道干预都只能通过颈部造口进行。虽然喉切除术后患者的气道阻塞并不常见,但如果不及时识别和了解改变的解剖结构,它可以迅速成为致命的。在这里,我们报告的病例患者与最近的TLE鳞状细胞癌,谁提出了农村急诊科(ED)急性呼吸窘迫。紧急医疗服务(EMS)提供者报告大量气管造口出血和缺氧,室内空气氧饱和度为55%。到达急诊科时,患者处于严重的急性窘迫状态,伴有活动性出血和部分气管造口阻塞,原因是一个大的凝胶状凝块。人工清除血块,加上气管支气管铸型,呼吸得到改善。持续出血通过胸骨上切迹指压、静脉注射氨甲环酸(TXA)和液体复苏来控制。实验室评估显示血红蛋白从最近出院时的12.1 g/dL显著下降到8.9 g/dL,需要输血两个单位的填充红细胞。患者病情稳定后转至三级护理中心,经支气管镜检查发现气管前腐蚀是出血的原因,最终出院时病情稳定。本病例强调了罕见的危及生命的气道阻塞,由于气管造口出血,急诊医学提供者应保持警惕,准备迅速采取行动,以确保气道安全,防止任何灾难性的后果。

Management of tracheostomal hemorrhage complicated by obstructing clot in a post-laryngectomy patient presenting to a rural emergency department.

Total laryngectomy (TLE) results in the permanent separation of the respiratory and digestive tracts, requiring all airway interventions to occur exclusively via a neck stoma. Although airway obstruction in post-laryngectomy patients is uncommon, it can rapidly become fatal without prompt recognition and understanding of the altered anatomy. Here, we report the case of a patient with a recent TLE for squamous cell carcinoma, who presented to a rural Emergency Department (ED) in acute respiratory distress. Emergency Medical Service (EMS) providers reported profuse tracheostomal bleeding and hypoxia, with an oxygen saturation of 55 % on room air. On arrival at the ED, the patient was in severe acute distress with active hemorrhage and partial tracheostoma obstruction due to a large, gelatinous clot. Manual removal of the clot, along with an attached tracheobronchial cast, resulted in respiratory improvement. Ongoing hemorrhage was controlled with digital pressure in the suprasternal notch, intravenous tranexamic acid (TXA), and fluid resuscitation. Laboratory evaluation revealed a significant drop in hemoglobin from 12.1 g/dL at recent discharge to 8.9 g/dL, necessitating transfusion of two units of packed red blood cells. The patient was stabilized and transferred to a tertiary care center, where bronchoscopy revealed an anterior tracheal erosion as the source of bleeding and was eventually discharged in stable conditions. This case highlights a rare occurrence of life-threatening airway obstruction due to TLE-related hemorrhage at the tracheal stoma, for which Emergency Medicine providers should remain vigilant and prepare to act swiftly to secure the airway and prevent any catastrophic outcomes.
