In cases of hemo-pericardium or serous effusion, puncture of the pericardium (paracentesis pericardii) is indicated to relieve pressure on the heart. The procedure involves making an incision near the sternum and using a trocar or aspirator to penetrate the pericardium carefully without damaging the heart. If pus is present in the pleural cavity, immediate drainage is necessary to prevent lung collapse or sepsis. This can be achieved through exploratory puncture followed by surgical intervention if needed.
<Callout type="important" title="Critical Procedure">Puncture of the pericardium must be performed with extreme care to avoid damaging the heart, internal mammary artery, and pleura.</Callout>
In cases where pus is confirmed in the pleural cavity, an incision should be made at the lowest point of the abscess for optimal drainage. For adults, resecting a rib may be necessary to ensure adequate exposure and drainage.

Post-operative care includes thorough irrigation of the cavity with sterile saline or peroxide solution, followed by proper dressing and drainage tube placement. Regular monitoring is essential for preventing complications such as persistent sinus or metastatic abscesses.
Key Takeaways
- Puncture of the pericardium is crucial in cases of hemo-pericardium or serous effusion to prevent heart compression.
- Immediate drainage of pus from the pleural cavity is essential to avoid lung collapse and sepsis.
- Proper post-operative care, including irrigation and dressing changes, is vital for preventing complications.
Practical Tips
- Always use a trocar or aspirator with caution when performing pericardial puncture to minimize risk of injury.
- Ensure thorough exploration before making an incision in the pleural cavity to locate the lowest point of pus accumulation.
- Regular monitoring and dressing changes are critical for preventing complications such as chronic sinus formation.
Warnings & Risks
- Improper technique during pericardial puncture can lead to serious injury, including damage to the heart or major blood vessels.
- Inadequate drainage in cases of empyema may result in persistent lung collapse and sepsis.
Modern Application
While modern medical practices have advanced significantly since 1915, the principles outlined here for urgent thoracotomy remain relevant. Techniques such as pericardial puncture and pleural drainage are still performed today but with more precise instruments and sterile techniques to minimize risk of infection. Understanding these historical methods provides a foundation for emergency responders who may need to perform life-saving procedures in austere environments.
Frequently Asked Questions
Q: What is the primary indication for pericardial puncture?
Pericardial puncture, or paracentesis pericardii, is indicated when there is hemo-pericardium or serous effusion that interferes with heart function.
Q: Why is immediate drainage necessary in cases of empyema?
Immediate drainage prevents lung collapse and sepsis. Delaying treatment increases the risk of permanent lung damage due to fibrosis or adhesions.
Q: What are the risks associated with resecting a rib during pleural cavity surgery?
Resecting too much bone can lead to chronic sinus formation, necrosis at the wound site, and persistent drainage issues.
