Pitfalls of Swan-Ganz catheterization

Area of Science:

• Cardiology
• Medical Devices
• Patient Safety

Background:

• The Swan-Ganz catheter is a critical tool for hemodynamic monitoring.
• Proper catheter placement is essential for accurate pulmonary artery wedge pressure (PAWP) measurement.
• Potential malpositioning can compromise patient care and lead to adverse events.

Purpose of the Study:

• To evaluate the incidence and consequences of peripheral Swan-Ganz catheter malpositioning.
• To identify indicators of incorrect catheter placement.
• To emphasize best practices for safe Swan-Ganz catheter utilization.

Main Methods:

• Sixty patients with apparently correctly positioned Swan-Ganz catheters were studied.
• Catheter balloon visualization was performed using radiopaque contrast medium.
• Pulmonary wedge pressures were assessed in relation to balloon inflation and catheter location.

Main Results:

• Sixteen out of 60 (26.7%) catheters were found to be in peripheral locations.
• In 15 of these 16 cases, eccentric balloon inflation occurred, preventing accurate PAWP measurement.
• One patient experienced hemoptysis, correlating with peripheral placement and eccentric inflation.

Conclusions:

• Peripheral Swan-Ganz catheter placement is a significant issue, impacting pressure readings.
• Eccentric balloon inflation is a key indicator of malposition.
• Avoiding redundant loops and ensuring placement in a large pulmonary artery are vital for safety and accuracy.
