10 Questions
What are common indications for thoracic surgery?
Lung cancer and esophageal diseases
What is a particular anesthetic challenge of thoracic anesthesia?
Controlling the airway during bronchoscopy
What is a common diagnostic procedure associated with thoracic surgery?
Mediastinoscopy
What is a potential consequence of inhalation of an organic foreign body?
Mucosal edema and airway hyperreactivity
What are the symptoms and signs of laryngeal or tracheal obstruction due to foreign body aspiration?
Cough, choking, and respiratory distress
What is recommended for induction during bronchoscopy in the presence of airway oedema?
Inhalational induction using sevoflurane or halothane in 100% oxygen
Why is intubation not recommended prior to rigid bronchoscopy for foreign body removal?
It may dislodge the foreign body distally
What is the main purpose of monitoring using pulse oximetry, ECG, non-invasive blood pressure, and capnography during bronchoscopy for foreign body removal?
To ensure cardiovascular stability and adequate oxygenation
Why is sedative premedication not recommended in the case of foreign body aspiration?
It can lead to increased airway resistance
How might oesophageal foreign bodies present with respiratory distress?
Due to internal compression of the trachea
Study Notes
Indications for Thoracic Surgery
- Common indications include lung cancer, pneumothorax, and esophageal cancer
Challenges of Thoracic Anesthesia
- One particular anesthetic challenge is managing one-lung ventilation, which is often required during thoracic surgery
Diagnostic Procedures
- A common diagnostic procedure associated with thoracic surgery is bronchoscopy, which allows for visualization of the airways and diagnosis of conditions such as foreign body aspiration
Consequences of Inhalation of Organic Foreign Body
- A potential consequence of inhalation of an organic foreign body is lung abscess or pneumonia
Symptoms and Signs of Laryngeal or Tracheal Obstruction
- Symptoms and signs of laryngeal or tracheal obstruction due to foreign body aspiration include wheezing, coughing, stridor, and respiratory distress
- Other signs may include increased respiratory rate, decreased oxygen saturation, and use of accessory muscles
Induction during Bronchoscopy
- During bronchoscopy in the presence of airway oedema, awake fibreoptic intubation is recommended for induction
Intubation prior to Rigid Bronchoscopy
- Intubation is not recommended prior to rigid bronchoscopy for foreign body removal because it can push the foreign body further into the airway, making removal more difficult
Monitoring during Bronchoscopy
- The main purpose of monitoring using pulse oximetry, ECG, non-invasive blood pressure, and capnography during bronchoscopy for foreign body removal is to detect and respond to potential complications such as hypoxia, respiratory failure, and cardiac arrhythmias
Sedative Premedication
- Sedative premedication is not recommended in the case of foreign body aspiration because it can increase the risk of respiratory failure and make it more difficult to diagnose and treat the underlying condition
Oesophageal Foreign Bodies
- Oesophageal foreign bodies may present with respiratory distress due to compression of the trachea or bronchi, or due to the foreign body being inhaled into the airway
