Dear Editor:
Tracheobronchial clot-induced airway obstruction is a life-threatening situation, requiring emergent intervention and expertise to prevent a catastrophic outcome. We report successful resuscitation of a kidney disease patient who developed complete airway obstruction and consequent cardiac arrest due to a large tracheobronchial blood clot during emergency bronchoscopy for continued hemoptysis.
We received a call for intubation of a 30-year-old male undergoing emergency bronchoscopy (day 5) for hemoptysis under general anesthesia. The patient had a history of kidney disease (details unavailable), hypertension for 4 years (Amlodipine 5 mg twice a day), and recurrent symptoms suggesting urinary tract infection (UTI) but was not on any medical follow-up protocol. The patient was admitted (day 1) for fever with chills and rigor for 4 days and decreased urination and bilateral foot swelling for 15 days. After baseline investigations, the patient was diagnosed with chronic kidney disease, hypertension, and UTI and started on broad-spectrum antibiotics, a fluid/salt restricted diet, packed red blood cell (2 units) transfusions, and hemodialysis. On chest skiagram, mediastinal lymphadenopathy was suspected. A subsequent computed tomographic scan of the thorax and abdomen confirmed it as necrotizing mediastinal-retroperitoneal lymphadenopathy with centrilobular nodules in the right middle lobe (Figure 1). The patient received two cycles of hemodialysis. On day 4, after a negative coronavirus disease 2019 (COVID-19) report, endobronchial ultrasound was performed through a flexible bronchoscopy (FB), and fine-needle aspirate (three times through a 21-G needle) samples were obtained from the right paratracheal lymph nodes (4R position) under local anesthesia. The patient had mild post-procedure bleeding but was otherwise stable. Later, the patient experienced an episode of mild hemoptysis. Therefore, tranexamic acid 1 g intravenously (IV) stat was administered, followed by 500 mg IV three times a day, fresh frozen plasma (one unit), and desmopressin nasal spray 2 puffs twice a day, and the right lateral resting position was advised. However, hemoptysis increased in severity, so the patient was rushed for emergency bronchoscopy under local anesthesia on day 5. However, the procedure was halted due to patient hypoxemia, and the anesthesia team sent a call for intubation.
Upon arrival, the vitals were heart rate 128/min, blood pressure 114/68 mm Hg, oxygen saturation (SpO2) 85% on 6 L of oxygen through a facemask, sinus rhythm, and normothermia. The patient was intubated by rapid sequence intubation using fentanyl 2 μg/kg IV, ketamine 1.5 mg/kg IV, and rocuronium 1 mg/kg IV. The trachea was intubated with an 8.0 size endotracheal tube (ETT), and manual ventilation with isoflurane (0.5%–2%) and 100% fraction of inspired oxygen was initiated. Over the next 10–15 minutes, the SpO2 improved to 100%. Next, FB was introduced into the ETT. Upon first glance, both fresh and clotted blood were completely occluding the right bronchus, occupying the carina, and obscuring the left bronchus. We attempted endoscopic clot removal by a cryoprobe, but after a few failed attempts and persistent blood oozing, bronchoscopy with a rigid bronchoscope (RB) was proposed (Supplementary Video 1). Therefore, we extubated the patient and introduced an RB into the trachea. Ventilation was provided through a port in the RB. After multiple failed attempts to retrieve the clots, continuous oozing of blood, and gradual increases in clot size, SpO2 began to decrease. Therefore, we immediately removed the RB and initiated mask ventilation. However, we experienced extreme resistance in the reservoir bag and could not achieve chest expansion. Meanwhile, the SpO2 continued to drop, and the patient developed pulseless sinus bradycardia. Therefore, cardiopulmonary resuscitation (CPR) was started, adrenaline 1 mg IV stat was given, and attempted ventilation through a facemask was continued. After 2 minutes of CPR, return of spontaneous circulation was achieved. On laryngoscopy, we observed a blood clot occluding the airway below the glottis. First, we attempted to remove it through a flexible suction catheter (14 Fr), but failed. Therefore, we introduced a Yankauer rigid suction catheter into the larynx, but again failed to remove the clot. However, the clot then was retrieved en bloc by slowly dragging it up under continuous negative suction pressure of the Yankauer catheter (Figure 2). Afterward, we inserted a 7.0-sized ETT into the trachea and observed adequate chest rise on manual ventilation without increased airway resistance. We inserted the FB into the ETT and observed a clear tracheobronchial tree without residual bleeding (Supplementary Video 1). The vitals returned to normal within 5 minutes. The patient received adrenaline nebulization and hydrocortisone 100 mg IV stat, was shifted to the intensive care unit under ventilation support, and was extubated the next day without any complications.
Tracheobronchial bleeding and clot formation are known complications of interventional airway procedures. Multiple attempts to remove the clot may further aggravate the airway edema, cause fresh bleeding, and increase the size of the blood clot due to ongoing trauma to the mucosa by the suction catheter or probe [1]. Ongoing bleeding further limits the visibility of the FB in such situations. The RB offers a larger bore size for better visibility and suction but compromises patient ventilation. The obstructing clot may act in a ball-valve mechanism to cause selective expiratory obstruction, which may precipitate as tension pneumothorax or may lead to complete airway obstruction with subsequent hemodynamic collapse and even mortality [1]. The alternative options include tracheal suction, cryoprobe, forceps, fibrinolytic agents, or embolectomy catheter [1-4]. In this patient, such a sequence precipitated as a life-threatening situation. The tracheobronchial blood clot was so large that it could not be retrieved either through cryoprobe, forceps, or suction under FB or RB guidance or sucked out with a flexible or Yankauer catheter. We attempted to pull the clot slowly through the Yankauer catheter. The rigid structure of the Yankauer catheter and its better suction pressure allowed the blood clot to attach to the catheter end, and we ultimately retrieved the entire clot in a single piece with the catheter. In conclusion, the Yankauer catheter might be an effective lifesaving tool for removing tracheobronchial blood clots in a crisis where conventional modalities are ineffective.
