THE IMPACT OF CERVICAL PLEXUS BLOCK (CPB) ON THE ANTI-NOCICEPTIVE PROTECTION DURING A. CAROTIS INTERNA (ACI) OPERATIONS
Materials and methods. 77 anaesthesia protocols during a. carotis interna (ACI) operations were analyzed. All the patients were divided into 3 groups. In the 1-st group a total intravenous anaesthesia — TIVA (propofol and fentanyl) was used. In the 2nd and 3rd groups was used combined anaesthesia: in the 2nd — TIVA + superficial CPB, in the 3 rd — combined anesthesia (sevorane+fentanyl+CPB). When analyzing the results, BP, BIS data, anaesthetic doses and the need for opioid analgesics were evaluated. Assessment of the postoperative pain quality was conducted within 48 hours of the postoperative period on a verbal assessment scale (VAS). Results. The need for fentanyl was considerably higher in the 1st group. The analysis of the BP data dynamics showed better stability in the 2nd and 3rd groups. Conclusions. TIVA +CPB provides better analgesia and reduces the need for opioid analgesics; greater stability of hemodynamic parameters during operation stages, as well as the best brain perfusion during a. carotis interna occlusion; postoperative analgesia and allows to avoid the early appointment of systemic analgesics.
