From the Guidelines
The primary treatment for subcutaneous emphysema is to address the underlying cause, such as managing pneumothorax, while providing supportive care, including administering supplemental oxygen and considering interventions like subcutaneous incisions or drains as needed. When managing subcutaneous emphysema, it's crucial to identify and treat the source, which often involves managing pneumothorax, chest trauma, or iatrogenic injury 1. Here's a concise approach:
- Identify and treat the source: This often involves managing pneumothorax, chest trauma, or iatrogenic injury.
- Supportive measures:
- Administer supplemental oxygen to aid reabsorption of trapped air
- Provide pain management with NSAIDs or opioids as needed
- Ensure proper positioning to maximize comfort
- Specific interventions:
- For mild cases: Observation and conservative management
- For moderate to severe cases: a. Subcutaneous incisions or "blow holes": Make small (1-2 cm) incisions in affected areas to release trapped air b. Subcutaneous drains: Insert fenestrated catheters to facilitate air drainage c. Negative pressure wound therapy: Apply to incisions to enhance air removal
- Monitor closely for complications such as respiratory distress or infection
- Continue treatment until clinical improvement is observed, typically within a few days to weeks It's also important to note that the development of surgical emphysema associated with pneumothorax involves an air-filled space being brought into communication with the subcutaneous tissues, which may occur in the presence of a malpositioned, kinked, blocked, or clamped tube 1. In life-threatening situations, more aggressive interventions like tracheostomy, skin incision decompression, and insertion of large bore modified subcutaneous chest drains have been used 1. The goal is to allow trapped air to escape while preventing further air accumulation, and oxygen therapy helps by creating a gradient that promotes faster reabsorption of subcutaneous air. Incisions and drains provide direct routes for air to exit the tissues, and close monitoring is essential to ensure resolution and detect any worsening of the condition.
From the Research
Treatment Options for Subcutaneous Emphysema
The treatment for subcutaneous emphysema can vary depending on the severity of the condition. Some of the treatment options include:
- Skin incisions, also known as "blow holes", to relieve symptoms 2
- Pleural drainage, subcutaneous insertion of pig-tail drains, iv cannulas or large bore drains 2
- Negative-pressure wound therapy dressing applied on typical blowhole incisions 3, 4
- Subcutaneous angiocatheter insertion to relieve the pressure of extensive subcutaneous emphysema 5
- Supportive care and prophylactic antibiotics for mild cases 6
Effectiveness of Treatment Options
The effectiveness of these treatment options can vary. For example:
- Skin incisions have been shown to be effective in relieving symptoms in some cases 2
- Negative-pressure wound therapy dressing has been shown to be effective in reducing the level of subcutaneous emphysema within 48 hours 4
- Subcutaneous angiocatheter insertion has been shown to be a safe and uncomplicated decompression technique to relieve extensive subcutaneous emphysema 5
Considerations for Treatment
When considering treatment options for subcutaneous emphysema, it is essential to take into account the severity of the condition and the individual patient's needs. In some cases, a combination of treatment options may be necessary to achieve the best outcomes. Additionally, prompt diagnosis and appropriate management are crucial to prevent further complications 6
