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. PATIENTS AND METHODS: Twenty-three patients with an arterial catheter were examined; the nonaffected arm was used as control. The use of the a. radialis/a. ulnaris ratio for the assessment of artery functioning was validated with 20 healthy individuals and the nonaffected control arm of the examined patients. Arterial function was measured with a Doppler monitoring device and a subjective assessment distress list. All patients were assessed before insertion and 1 day, 5 days, and 30 days after removal. Data were analyzed by means of multivariate analysis of variance and t test. RESULTS: A significant decrease in the a. radialis/a. ulnaris ratio was found 1 day and 5 days after removal (t1 P = .04, t5 P = .003, and multivariate analysis of variance P = .033), against no significant change after 30 days. Subjective assessment showed no relevant clinical negative impact. CONCLUSION: There is significant change in the hemodynamic function of the artery 1 day and 5 days after removal, but this significant change disappears after 30 days. An arterial monitoring catheter causes a functional arterial change in the affected arm in the short term and no significant difference in the long term. Therefore, arterial catheterization is a safe procedure after short-term cannulation. Second, the systolic blood pressure ratio of the a. radialis/a. ulnaris is a valuable tool in the assessment of the hemodynamic function of the a. radialis after radial cannulation.
