Values of Enhanced Monitoring by EEG Recording (Narcotrend) for Sedation in Endoscopic Ultrasound

- Registration Number
- NCT02705079
- Lead Sponsor
- Ruhr University of Bochum
- Brief Summary
Endoscopic examinations and particularly long-lasting interventions can be uncomfortable for patients. Pain and vasovagal reactions are common. Therefore, the implementation is generally recommended under sedation and also carried out in practice here.
The vital signs monitoring to avoid complications is dictated by current national guidelines. Necessary measures of monitoring include pulse oximetry and blood pressure measurements. In patients with severe heart disease an ECG recording should be used additionally. Moreover, the guidelines require that the sedation is clinically monitored continuously to avoid an unwanted anesthetic stage.
Such evaluation, however, is often difficult under clinical conditions and even counterproductive, since a constant response and tactile stimulation of the patient (to check clinically the depth level of sedation ), interrupts endoscopic complex intervention. However, clinical most relevant aspect is the avoidance of unrecognized transition of patients from the stage of deep sedation in an anesthetic stage.
Current recommendations do not take into account new study results from a gender perspective, which showed that women and men need a different wake-up time using the EEG derivation means by using teh Narcotrend after total intravenous anesthesia, which may be due to different total doses of sedatives needed. However, the research group has been demonstrated in a previous study that most likely caused by the use of EEG monitoring (Narcotrend) an effective adaptation of sedation, in particular a more rapid recovery time by a lower dose of the administered sedative for a continuous sedation stage D0-D2 endoscopic retrograde cholangiopancreatography-(ERCP).
In the presented study the investigators evaluate the extent of gender differences in the wake-up time after sedation with propofol during endoscopic ultrasound when using EEG monitoring.
- Detailed Description
Endoscopic examinations and particularly long-lasting interventions can be uncomfortable for patients. Pain and vasovagal reactions are common. Therefore, the implementation is generally recommended under sedation and also carried out in practice here.
In interventional and longer lasting interventions (for example, endoscopic ultrasonography, ERCP) as opposed to purely diagnostic examinations is often deep sedation.Use of propofol in terms of sedation efficacy and the wake-up time or quality is superior to the use of benzodiazepines (plus opiates), while patient safety is the same.

Included are patients who undergo endoscopic ultrasonography, which is performed under sedation with propofol.
