Surgical Emphysema: Causes, Symptoms, Prevention, and Treatment

Surgical (subcutaneous) emphysema is air trapped in subcutaneous tissues, occurring in ~10% of surgeries, especially thoracic, neck, or laparoscopic procedures.

Presentation

• Onset: usually within 24 hours post-op.
• Signs: crepitus (crackling on palpation), swelling, fullness.
• Duration: typically resolves in 1–2 weeks as air resorbs.

When Intervention Is Needed

• Significant swelling compromising airway (neck) or ventilation (chest).
• Signs of infection (redness, fever, purulent drainage).
• Tissue necrosis risk from pressure.

Prevention Strategies

• Closed suction drainage systems.
• Avoid excessive intraoperative suction/irrigation.
• Meticulous closure of fascial planes.
• Pressure dressings on high-risk sites.

Treatment

• Conservative: observation, head elevation, oxygen (promotes nitrogen washout).
• Needle aspiration for tense collections.
• Chest tube if pneumothorax coexists.
• Rarely: surgical decompression for compartment syndrome.

Most cases are benign and self-limiting. Clinical vigilance identifies the few requiring action.
