Brief Summary

From an anesthesiological perspective, carotid endarterectomy (CEA) is an operation that is increasingly being performed with locoregional techniques and sedation. The aim of this observational study was to compare dexmedetomidine with midazolam and fentanyl during CEA in terms of perioperative adverse events, patient, anesthetist, and surgeon satisfaction, as well as the possible reduction in clamping time and the number of times additional local anaesthesia is needed. Sixty patients listed for CEA were enrolled and two types of sedation were used, both protocols widely used in our hospital, resulting in the formation of two groups of patients. Both the intermediate and superficial cervical plexus blocks were administered, and the patients in Group 1 were sedated with midazolam and fentanyl, and Group 2 was sedated with dexmedetomidine. The investigators examined comorbidities, surgical time and clamping, and possible intraoperative use of local anaesthetics and intraprocedural complications, and follow-up at 180 days to observe any residual deficits. The data were analysed with Statistical Package for Social Science (SPSS) Statistics 25 (IBM).

Healthy VolunteersNo

Sampling MethodNon-Probability Sample
Study Population

The minimum target set to start the study was the enrolment of 60 patients to be divided equally into two groups, since our group of anaesthetists uses, without preference, two sedation protocols, in addition to cervical plexus blockade, for TEA operations in vascular surgery, both of which are approved in the literature and in internal hospital procedures

You may qualify if:

  • Patients who were candidates for carotid endoarterectomy elective surgery
  • Age \>18yr
  • Ability to provide consent for the procedure

You may not qualify if:

  • severe liver failure (Child-Pugh classes B or C) or severe hypoproteinemia (albuminemia \< 3.0 g/dl)
  • age \<18yr
  • baseline heart rate \<50 bpm; II or III grade atrioventricular block without a pacemaker
  • malignant hyperthermia suspected or established
  • psychiatric disorders
  • emergency surgery
  • inability to provide consent for the procedure
