Key result

A new wrist continuous noninvasive arterial pressure monitoring system showed acceptable agreement with invasive radial artery measurement (mean difference for SAP -2.09±5.39 mmHg).

Why the study?

Does a new wrist continuous noninvasive arterial pressure monitoring system provide accurate measurements compared to invasive radial artery measurement in patients undergoing elective surgery?

Population

60 patients undergoing elective surgery under general anesthesia

Type

RCT (n=60)

Randomization

Randomized

Structured PICO

Does a new wrist continuous noninvasive arterial pressure monitoring system provide accurate measurements compared to invasive radial artery measurement in patients undergoing elective surgery?

P
Population
60 patients undergoing elective surgery under general anesthesia.
I
Intervention
New wrist continuous noninvasive arterial pressure (CNAP) monitoring system
C
Comparator
Invasive arterial pressure (IAP) monitoring via arterial catheter inserted at the radial artery in the contralateral arm
O
Outcome
Agreement between measurement methods (systolic, mean, and diastolic arterial pressure) assessed by the Bland-Altman methodsurrogate

Main Result

Mean Difference: -2.09

A new wrist continuous noninvasive arterial pressure monitoring system demonstrated acceptable agreement and interchangeability with invasive radial artery monitoring in patients undergoing elective surgery.

Li et al. (2017) conducted an RCT in Elective surgery under general anesthesia (n=60). Wrist continuous noninvasive arterial pressure (CNAP) monitoring system vs. Invasive arterial pressure (IAP) monitoring was evaluated on Agreement between measurement methods (wrist CNAP vs IAP) (MD for SAP -2.09 mmHg). A new wrist continuous noninvasive arterial pressure monitoring system showed acceptable agreement with invasive radial artery measurement (mean difference for SAP -2.09±5.39 mmHg).
