Background: Over-insertion of a pulmonary artery catheter (PAC) can cause serious complications, such as pulmonary embolism and pulmonary artery rupture. Careful management is essential.

Methods: This study investigated relationships between patient parameters and appropriate PAC insertion length. A function on the chest X-ray display was used to measure the curve. In Study 1, we investigated concordance using intraclass concordance coincidence (ICC) between recorded insertion length of the PAC and actual inserted length. We reviewed recorded insertion data from patients’ anesthesia records and measured actual inserted length. In Study 2, we measured and estimated the appropriate insertion length using chest X-rays taken just after surgery. Multiple logistic regression was performed to investigate relationships between patient background parameters and appropriate insertion length.

Results: For Study 1, recorded insertion length was 41.2±2.7cm and actual inserted length was 41.9± 3.1cm. ICC (2,1) was 0.867, which shows a high correlation. For Study 2, height and cardiac width on preoperative chest X-rays were significant factors determining appropriate PAC length. The multiple regression equation for appropriate PAC length (z) with height (x) and cardiac width (y) was calculated as z(cm) = 0.1x +0.8y+18.1. Height and cardiac width were significant factors determining appropriate PAC insertion length.

Conclusions: We calculated an equation for the relationship between height and cardiac width to obtain the appropriate PAC insertion length.
