The purpose of this study is to compare the hemodynamics effects of two usual hypnotic agents (LENOXe ™ (xenon 100 % v/v) and sevoflurane) during a general anesthesia for carotid endarterectomy in elderly patients. The hypothesis is that the use of the LENOXe ™ (xenon 100 % v/v) allows to obtain per-operating hemodynamic stability non inferior than with sevoflurane.

Further study details as provided by Air Liquide Santé International:

Primary Outcome Measures:
  • Standard deviation of the values of systolic blood pressure (SBP)collected per-operatively every minutes(BIOPAC ® MP150) Values of SBP over or under thresholds during and out of the clamping period, if so vasopressive/ hypotensive treatment used [ Time Frame: Pre-op, every min from 1-90 min during maintenance phase ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • cardiovascular, general, hepatic and renal tolerance to xenon. Quality and time of awakening, recovery index (IR);Post-op pain (EVA)and consumption of analgesic; Inflammatory Syndrome (cytokine profile); Subjective comfort of the patient [ Time Frame: During the whole anesthetic procedure and the postoperating time until 24 hours after discharge from the recovery room / intensive care unit and return to the ward ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 84

Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: sévoflurane
hypnotic use in standard general anesthesia
Drug: sévoflurane
Inhalation gas; dose allowed: 1,4 %; the duration of the treatment will be defined through anesthesia-time for a carotid surgery
