title: [Comparison of the influence of general and regional anesthesia on basic haemodynamic parameters during carotid endarterectomy].
abstract: Carotid endarterectomy (CEA) is a preventive operation to reduce the incidence of embolic and thrombotic cerebral stroke. CEA carries a significant perioeperartive mortality rate from stroke and myocardial infarction, which may even approach 5%. Thus, anesthetic and surgical techniques are constantly under scrutiny to try to reduce this relatively high incidence of morbidity and mortality. Anesthetic technique for CEA is divided to general (GA) and regional (RA) anesthesia, performed by cervical plexus block. The aim this study was to examine changes of basic haemodynamic parameters, which routinely fallows during CEA in condition of GA and RA. After obtaining institutional approval and informed consent, we randomized 50 patients scheduled for CEA (Tab. 1) in two groups (GA and RA). We fallow blood pressure: systolic (BPs), mean (BPm), diastolic (BPd), heart rate (HR), and RPP index at the examined patients. The examination performed in six control times: before induction of anesthesia (T1), 10 minutes after beginning of operation (T2), 5 minutes after cross clamping of arteria carotis (T3), 5 minutes after declamping arteria carotis (T4), 10 minutes (T5) and 2 hours after operation (T6). The results of study shows significant changes of blood pressure (BPs and BPm) and RPP index in T2 time in patinets undergoing GA. The changes occurred under influence of induction agent thiopental. These changes were in homeostatic range. In RA patinets, no haemodynamic changes registrated in control times. Therefore, from haemodynamic aspect RA was superior to GA.
