Summary
This study shows that using only analgesia for carotid endarterectomy in intubated patients allows for effective monitoring of neurological function during carotid clamping. This anesthetic approach ensures patient safety and facilitates clinical evaluation.
Area of Science:
- Anesthesiology
- Neurosurgery
- Vascular Surgery
Background:
- Carotid endarterectomy (CEA) is a surgical procedure to remove plaque from carotid arteries.
- Anesthesia choices for CEA include general or locoregional anesthesia.
- Locoregional anesthesia allows direct assessment of neurological function during carotid clamping.
Purpose of the Study:
- To evaluate an anesthetic technique using only analgesia in intubated patients undergoing CEA.
- To assess the feasibility of monitoring motor function during carotid clamping under this anesthetic protocol.
- To determine the safety and efficacy of this approach in CEA.
Main Methods:
- Forty-eight patients (ASA II-III) underwent CEA.
- Anesthetic protocol involved remifentanil and propofol infusion, with orotracheal intubation under local anesthesia.
- Continuous non-invasive hemodynamic monitoring, including transesophageal Doppler echocardiography, was performed.
Main Results:
- The anesthetic objective was achieved in all patients.
- Hemodynamic alterations (bradycardia, hypotension) were transient and corrected promptly.
- Postanesthetic recovery was rapid (<4 min); no anesthesia-related complications occurred.
Conclusions:
- This analgesic-based anesthesia technique allows continuous monitoring of neurological status during CEA.
- Adequate ventilation and consciousness level facilitate clinical evaluation of carotid clamping effects.
- Strict protocol adherence and continuous monitoring are crucial for this procedure's success.
