Cohort of 40 patients undergoing general anesthesia
csem bp system 2015-md-0022
At the onset of general anesthesia: continuous measurements of radial arterial blood pressure values (arterial catheter, via a commercial PHILIPS IntelliVue MP50 monitor) continuous estimates of optical blood pressure values (optical blood pressure system, via Swissmedic approved measuring device 2015-MD-0022 developed by CSEM) will be recorded.

Official title Comparison of an Optical System to Continuously Measure Arterial Blood Pressure Against a Gold-standard Arterial Catheter
Principal investigator Patrick Schoettker
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.
