Subclavian vein cannulation can lead to tension pneumothorax, causing critical hypoxia and ECG changes. Prompt intervention resolved these serious complications, highlighting the importance of timely diagnosis and treatment.

Area of Science:

  • Cardiology
  • Pulmonology
  • Critical Care Medicine

Background:

  • Subclavian vein cannulation is a common procedure for central venous access.
  • Complications, though rare, can be severe and include pneumothorax.

Observation:

  • A 69-year-old male developed bilateral tension pneumothorax after attempted subclavian vein cannulation.
  • The patient presented with hemodynamic compromise, critical hypoxia, and characteristic electrocardiographic changes.

Findings:

  • Electrocardiogram (ECG) showed ST elevation, decreased QRS amplitude, and diminished precordial R voltage.
  • Decompression of the right pleural space led to the resolution of all ECG abnormalities.

Implications:

  • Tension pneumothorax should be considered in patients with hemodynamic instability and hypoxia following central line placement.
