| Abstract | In comparison to general anaesthesia, subarachnoidal (SAB) and epidural (EPA) anaesthesia have numerous advantages. It is, therefore, of vital importance to be acquainted with all the changes occurring in the cardiovascular system when administering these. The aim of our study was to analyse the haemodynamic changes taking place in anaesthetized and non-anaesthetized areas during lumbal SAB and EPA of patients, both with and without previous cardiovascular diseases. The influence of high, tight leg bandaging on above-mentioned changes was also studied. There were 200 patients (ASA I-III) included in the study. The control group (KS) was formed of 100 patients with neither history of disease data nor clinical signs of any cardiovascular illness. The cardiovascular group (KVS) also consisted of 100 patients who were, prior to the operation, diagnosed to be suffering from arteriosclerosis or a leg vein system disease. Each group was further divided into four subgroups, depending on the type of anaesthesia they were administered and whether their legs were bandaged (b) or not. As a result KS subgroups were K SAB, K SAB b, K EPA and K EPA b, while KVS subgroups were KV SAB, KV SAB b, KV EPA and KV EPA b. For measuring the blood velocities Doppler sonography apparatus Sonicaid blood velocimeter 481 and an 8 Mhz probe were used. The flows measured were those through the common carotid artery (ACC), common femoral artery (AFC), posterior tibial artery (ATP) and common femoral vein (FVC). The following parameters were taken : - ACC-sistolic blood flow velocity (Ac), diastolic blood flow velocity (Dc) and resistance index (RP). - AFC-sistolic blood flow velocity (Af) and diastolic reflux velocity (DRf). - ATP-sistolic blood velocity (At) and diastolic reflux velocity (DRt). - VFC-maximum vein flow velocity (MVP) and maximum vein reflux velocity (MVR) by means of pressure-on-stomach test (TPT).
