Abstract:

Objective

To investigate the best catheterization method and the effect of semi-open technology in a dog extracorporeal membrane oxygenation (ECMO) model.

Methods

Central venous cath-eterizations were placed via right internal jugular vein, and artery piezometer tubes were placed in radial artery to connect multifunctional electrocardiograph monitor. All dogs underwent ECMO support through semi-open technology via femoral artery and femoral vein cannulation. The success rate, time expenditure, blood loss and incidence of complications were analyzed.

Results

Nineteen of the 20 animals were per-formed successfully. The mean duration of puncture and cannulation was (41±18) min, the blood loss was (16±8) ml, and postoperative hemorrhage occurred in 3 cases (15%).

Conclusion

The femoral artery and vein puncture under direct vision via semi-open technology is a safe and effective method, also a rela-tively time saving method.

Key words: Extracorporeal membrane oxygenation, Catheterization technology, Femoral artery and vein, Dog
