Comparison of invasive and noninvasive blood pressure measurements in critically ill patients receiving norepinephrine.

ABSTRACT:

Background

Blood pressure monitoring is crucial in critically ill patients, with invasive arterial blood pressure (IABP) recognized as the gold standard. Noninvasive blood pressure (NIBP) is widely used but may differ from IABP, particularly in patients receiving norepinephrine. This study evaluated the agreement between IABP and NIBP and the impact of the norepinephrine dosage on the accuracy of NIBP in septic shock patients.

Methods

This prospective observational study was conducted in a 36-bed ICU (April 2022-April 2023) and included 84 patients with septic shock receiving norepinephrine. IABP was measured via a radial artery catheter, and NIBP was recorded simultaneously from the contralateral arm. Patients were grouped by norepinephrine dose: ≤ 0.25, 0.25-0.50, and ≥ 0.
