Evaluation of Transcranial Doppler Vasoconstrictor Vasoreactivity During General Anesthesia in Hypertensive Patients

NCT03897790 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2019-09-26

No results posted yet for this study

Summary

During a general anesthesia, people over 65 years old and hypertensive, have a modification of the vasoreactivity and their cerebral blood flow under vasoconstrictor such as norepinephrine or phenylephrine. We study the variation of the average velocity of the average cerebral artery under vasoconstrictor and during a modification of End Tidal CO2 (EtCO2) by transcranial Doppler.
