Summary

Carotid endarterectomy (CEA) is a high risk surgical and anesthesiological procedure. It is an essential part of stroke-prevention strategies, however the incidence of CEA related peri-operative stroke is between 5% and 10%. These procedures can be performed either in general or regional anaesthesia. We hypothesized that an appropriate awake sedation is able to decrease patient's distress and an improved satisfaction can be reached.

Description

We aim to explore the stress response of patients randomized according to different sedation protocols: (i) per os premedication only with alprazolam (BDZ group) or (ii) premedication with alprazolam combined with target control infusion (TCI) of propofol (BDZ+TCI) for awake carotid endarterectomy. A total of 50 consecutive patients with significant carotid artery stenosis will be enrolled into this prospective randomised study. All surgeries will be performed in regional anaesthesia. As premedication, all patients took 0.25 mg alprazolam 30 minutes before the procedure. After randomization 25 patients will be grouped to both arms of the study: either to "sedation with target controlled propofol infusion", or to "only premedication". Stress markers, such as cortisol plasma levels will be serially analysed: prior to surgery (T1), before (T2) and after release of carotid clamp (T3), at 2 (T4) and 24 post-operative hours (T5). Alprazolam levels were also measured before and after the surgery.
