Official title: Comparison of an Optical System to Continuously Measure Arterial Blood Pressure Against a Gold-standard Arterial Catheter

Status Completed

Clinical Trial Summary

Comparison of an optical method to continuously measure blood pressure against an invasive arterial catheter.

Clinical Trial Description

The measurement of blood pressure during anesthesia is commonly performed by the inflation of a brachial cuff providing only intermittent blood pressure measurements. In some case, it is required to add a continuous invasive monitoring of blood pressure, via the insertion of an arterial catheter. Unfortunately, the related morbidity is not negligible. To limit the consequences of such a gesture, some developments have been done in the past to allow for continuous non-invasive measurements of blood pressure during anesthesia. Unfortunately, most of these devices are subject to important limitations and constraints of use.

A new system has been designed by CSEM consisting of an optical system fixed on patient's skin, absolutely non-invasive and easy to use. In order to study the reliability of this device, the investigators plan to compare its blood pressure estimates against gold-standard arterial catheter measurements during induction of general anesthesia on:

• 40 patients wearing the optical system at the chest.

• and 40 patients wearing the optical system at the fingertip ;
