Conditions
Brief summary
In many surgical procedures, anaesthesiological care is provided according to the best scientific and clinical information available. However, since hemodynamic monitoring until recently did not allow for beat-to-beat information of the haemodynamical changes, many fast-changing events may have been unnoticed or have not been investigated as precisely as is possible today. Moreover, in several surgical procedures - like eye surgery - the invasiveness of the classical haemodynamical monitoring devices was of such a degree that until now, in these circumstances these vital parameters were not investigated yet. Therefore, the availability of this new device, which allows for noninvasive beat-to-beat assessment of these haemodynamical parameters gives a unique opportunity to investigate our anaesthesiological management and to elucidate whether improvements are desirable and possible. The Nexfin monitor consists of a cuff-micromanometer that is located around the third finger. It simultaneously uses continuous pressure readings and light-absorption spectrometry to determine valuable haemodynamical information. Data is recorded and available for subsequent offline analysis.
