Prospective comparative study on the hemodynamic and functional consequences of arterial monitoring catheters in intensive care patients on the short and long term.

Introduction: In intensive care wards, arterial catheters are a relevant instrument to monitor vital functions. However, the effect of arterial catheterization on hemodynamic function in elective patients in the short and long term is unknown.

Aim: The objective of this study was to examine the possible damaging effects of arterial monitoring catheters on arterial functioning in intensive care patients after elective surgery.
