Pneumothorax

This week, we'll explore the latest clinical guidelines on pneumothorax, a condition characterized by the presence of air in the pleural space, which can lead to partial or complete lung collapse. Accurate diagnosis is critical and involves patient history, physical examination, and imaging studies such as chest X-rays or CT scans.

Symptoms like sudden chest pain and shortness of breath, along with physical signs like diminished breath sounds, guide initial assessments. Pneumothorax can be classified as spontaneous (primary or secondary), traumatic, or iatrogenic, each requiring a tailored approach based on underlying causes and patient presentation.

Management strategies vary depending on the severity and type of pneumothorax. For small, asymptomatic cases, observation and supplemental oxygen may suffice, while more significant cases may require needle aspiration, chest tube insertion, or surgery. Recent guidelines emphasize the importance of individualized treatment plans and the growing role of minimally invasive procedures in effectively managing pneumothorax, particularly in recurrent or persistent cases.

Guidelines on the evaluation and management of pneumothorax are from the European Association for Cardio-Thoracic Surgery (EACTS/ERS/ESTS 2024), the European Reference Network on GENetic TUmour RIsk Syndromes (ERN GENTURIS 2024), and the British Thoracic Society (BTS 2023), among others.

Transforming Respiratory Care with Innovation

Millions in the U.S. live with chronic lung diseases such as asthma and COPD, frequently giving rise to significant levels of hospitalizations and ER visits annually. The use of traditional stethoscopes can result in early signs being missed and are among several factors that can limit the quality of auscultation - ultimately delaying treatment and increasing healthcare costs.

ChestPal™ Pro is a smart stethoscope that provides accurate and reliable lung sound detection, converting sounds into visual spectrograms aiding diagnosis. What’s more, lung sounds can be recorded, and shared with colleagues effortlessly. Thus serving as a valuable tool in clinical practice.  

Why It Matters:

• Prevalence: Over 34 million Americans live with chronic lung diseases like asthma and COPD.
• Current Practice Limitations: The use of traditional stethoscopes can result in faint lung sounds being missed, delaying diagnosis and treatment.

For a full review of pneumothorax guidelines, head over to Pathway. We’ll cover some key takeaways below (with the recommendation strength in parentheses). 

1) Diagnostic Investigations

• Consider classifying primary spontaneous pneumothorax as large in the presence of a visible rim along the entire axillary line, ≥ 2 cm between the lung margin and the chest wall at the hilum level. (C)
• Classify pneumothorax as a tension pneumothorax when it results in respiratory distress or hemodynamic failure. (B)
• Consider obtaining a frontal CXR acquired in inspiration, without expiratory films, in patients with suspected primary spontaneous pneumothorax to diagnose pneumothorax and assess its size. (E)
• Avoid establishing the diagnosis of primary spontaneous pneumothorax solely based on chest ultrasound in the absence of signs of severity. (D)
• Obtain a chest ultrasound to complement or replace conventional CXR for diagnosing pneumothorax, depending on the clinical setting and the need for rapid results. (A)

2) Medical Management:

• Consider offering outpatient management for the initial treatment of primary spontaneous pneumothorax in centers with appropriate expertise and pathways to manage patients as outpatients. (C)
• Consider offering conservative management of primary spontaneous pneumothorax in selected cases (minimally symptomatic and clinically and radiologically stable), regardless of the size of the pneumothorax. (C)
• Offer pain management based on multimodal analgesia in patients with medically treated (needle aspiration, drainage, or conservative management) primary spontaneous pneumothorax. (B)
• Perform emergency chest decompression through an anterior (mid-clavicular line at the 2nd intercostal space) or axillary (mid-axillary line at the 4th intercostal space) approach in patients with confirmed tension primary spontaneous pneumothorax. Use dedicated equipment (thoracentesis kit) or any other needle aspiration device as available. (B)
• Advise smoking cessation in patients with pneumothorax, as smoker patients are more likely to have a recurrent episode. (B)
• Offer smoking (and any other smoked substances) cessation support in patients to minimize the risk of primary spontaneous pneumothorax recurrence. (A)
• Avoid advising strict bed rest in patients with primary spontaneous pneumothorax. (D)

Needle decompression and chest tube locations and indications

3) Therapeutic Procedures:

• Perform needle aspiration over chest tube drainage for the initial management of primary spontaneous pneumothorax. (B)
• Perform chest tube drainage as a first-line option to remove air from the pleural space in patients with large primary spontaneous pneumothorax without signs of immediate severity. (B)
• Consider performing emergency chest tube drainage in patients with any of the following:
  • simultaneous bilateral primary spontaneous pneumothorax with signs of severity or large primary spontaneous pneumothorax
  • hemopneumothorax with signs of severity or large hemopneumothorax
  • primary spontaneous pneumothorax with confirmed pleural adhesion and signs of severity or large primary spontaneous pneumothorax. (E)
• Consider performing chemical pleurodesis to prevent a secondary spontaneous pneumothorax in adult patients, such as in patients with severe COPD significantly decompensated in the presence of a pneumothorax, even during/after the first episode. (C)
