# Nexfin®-Monitoring System

**Official Title:** Electronic Registration of Noninvasively Acquired Hemodynamic Parameters Using Nexfin®-Monitoring System

**NCT ID:** [NCT01362335](https://clinicaltrials.gov/study/NCT01362335)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 120
- **Lead Sponsor:** University Medical Center Groningen
- **Conditions:** Surgery
- **Start Date:** 2011-05
- **Completion Date:** 2011-09
- **CT.gov Last Update:** 2024-04-17

## 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.
