Continuous finger-cuff versus intermittent arm-cuff blood pressure monitoring during outpatient surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This before-and-after interventional cohort compares intermittent oscillometric arm cuff measurements to continuous noninvasive blood pressure (cNIBP) recorded with VitaWave finger cuffs and the HemoSphere Vita Monitor during elective noncardiac outpatient surgeries. Adult patients (≥18 years) with ASA physical status ≥2 who provide consent and require standard arm cuff monitoring will have finger-cuff cNIBP recorded concurrently during their procedures. Patients with pregnancy, existing arterial catheter, large inter-arm systolic differences, inability to place cuffs, Raynaud's disease, or finger/hand anatomy preventing proper cuff placement are excluded. Continuous and intermittent blood pressure recordings will be analyzed for agreement, timing of changes, and feasibility of finger-cuff monitoring in the outpatient surgical setting at the University of Rochester Medical Center.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. Signed informed consent
2. Age ≥ 18 years
3. American Society of Anesthesiologists (ASA) Physical Status ≥ 2
4. Scheduled for elective noncardiac surgery with intermittent arterial blood pressure monitoring using oscillometric arm cuff

Exclusion Criteria:

1. Patient who is known to be pregnant
2. Patient with existing or planned arterial pressure catheter
3. Patient in whom systolic arterial pressure differs by more than 20 mmHg between the right and left arms
4. Inability to place oscillometric cuff on the subject's upper extremity
5. Extreme contraction of the smooth muscle in the arteries and arterioles of the lower arm and hand, such as may be present in patients with Raynaud's disease
6. Finger or hand deformity that prevents proper placement of finger cuff by visual inspection
7. Inability to place finger cuffs due to subject anatomy, condition, or obstructive paraphernalia (such as false nails)
