Zorluk: OrtaSurgical and Procedural Interventions

A 5454-year-old man is brought to the emergency department by emergency medical services after coughing up approximately 600600 mL of bright red blood over the past two hours. He has a history of treated pulmonary tuberculosis and residual cavitary disease in the left upper lobe. On arrival, he continues to cough up copious amounts of blood. His temperature is 37.1∘C37.1^\circ\text{C} (98.8∘F98.8^\circ\text{F}), blood pressure is 105/65105/65 mmHg, heart rate is 122122/min, and respiratory rate is 2828/min. Pulse oximetry shows an oxygen saturation of 86%86\% on room air. Auscultation reveals coarse rhonchi over the left hemithorax and clear breath sounds on the right. Intravenous access is established. Which of the following procedural interventions are immediately indicated? (Select all that apply)

  1. Selective endotracheal intubation of the right mainstem bronchusCevap
  2. Rigid bronchoscopyCevap
  3. C
    Flexible bronchoscopy
  4. D
    Computed tomography angiography of the chest
  5. E
    Urgent left thoracotomy and lobectomy

Cevap

The correct interventions are selective endotracheal intubation of the right mainstem bronchus and rigid bronchoscopy.
The correct interventions are selective endotracheal intubation of the right mainstem bronchus and rigid bronchoscopy. In massive hemoptysis (typically defined as >600>600 mL/24 hours or an amount causing hemodynamic or respiratory instability), the primary cause of death is asphyxiation from blood flooding the airways, not exsanguination. Therefore, the immediate priority is securing the airway and protecting the non-bleeding lung. Because the patient's clinical signs (history of tuberculosis, left upper lobe cavitary disease, and left-sided rhonchi) point to a left-sided source, selective intubation of the right mainstem bronchus effectively isolates the bleeding. Rigid bronchoscopy is the procedural intervention of choice because its large-diameter suction channel can clear massive amounts of blood, allowing for adequate ventilation, visualization, and potential local therapeutic interventions (e.g., balloon tamponade).

Adım Adım Çözüm

1
Assess the patient's hemodynamic and respiratory status.
The patient is in acute respiratory distress with hypoxia (86%86\% on room air) and tachycardia due to massive hemoptysis (>600>600 mL/24h).
Immediate life threats must be identified to prioritize the airway, breathing, and circulation (ABCs).
2
Determine the likely source of bleeding based on clinical findings.
The history of left upper lobe cavitary disease and localized left-sided rhonchi indicate the bleeding is originating from the left lung.
Localizing the bleeding is critical for determining appropriate airway positioning and protection strategies.
3
Select the most appropriate initial procedural interventions.
Selective right mainstem intubation and rigid bronchoscopy are chosen.
Right mainstem intubation isolates and protects the non-bleeding lung from asphyxiation. Rigid bronchoscopy is required to clear massive amounts of blood and secure the airway.

Anahtar Kavram

In the management of massive hemoptysis, the immediate priority is preventing asphyxiation by securing the airway, protecting the non-bleeding lung (e.g., via selective mainstem intubation), and utilizing rigid bronchoscopy for effective suctioning and visualization.
