Key result

ClearSight continuous blood pressure monitoring yielded mean arterial pressures identical to intra-arterial catheters (P=0.957), despite significant differences in systolic pressures (P<0.001).

Why the study?

Continuous blood pressure monitoring using pulse contour technology with ClearSight required evaluation as a noninvasive alternative to arterial lines in pediatric patients.

Does continuous blood pressure monitoring using the ClearSight device accurately measure blood pressure compared to an intra-arterial catheter in pediatric ICU patients?

Population

10 children younger than 18 years in a pediatric ICU requiring an arterial line

Comparison

ClearSight finger cuff monitoring vs intra-arterial catheter and automated cuff measurements

Design

Observational comparative study

Overview

ClearSight may enable noninvasive pediatric BP monitoring in select ICU cases; leaves open prospective validation against arterial lines before adoption.

Observational (n=10)

Structured PICO

Does continuous blood pressure monitoring using the ClearSight device accurately measure blood pressure compared to an intra-arterial catheter in pediatric ICU patients?

P
Population
10 pediatric ICU patients younger than 18 years requiring an arterial line, contributing 213 blood pressure measurements.
E
Exposure
Continuous blood pressure monitoring using pulse contour technology with the ClearSight monitoring device (finger cuff).
C
Comparator
Intra-arterial catheter and automated cuff measurements.
O
Outcome
Accuracy of systolic, diastolic, and mean arterial pressures (MAP) compared to intra-arterial catheter.surrogate

Main Result

p-value: p=<0.001 for systolic/diastolic, 0.957 for MAP

The ClearSight device provides accurate mean arterial pressure measurements comparable to an intra-arterial catheter in pediatric ICU patients, though systolic and diastolic measurements differ.

Cite This Study

Alharash et al. (2020) conducted an observational in Pediatric ICU patients requiring an arterial line (n=10). ClearSight monitoring device vs. Intra-arterial catheter was evaluated on Systolic, diastolic, and mean arterial pressures (MAP) (p=<0.001 for systolic/diastolic, 0.957 for MAP). ClearSight continuous blood pressure monitoring yielded mean arterial pressures identical to intra-arterial catheters (P=0.957), despite significant differences in systolic pressures (P<0.001).
