[Subarachnoid anesthesia in patients with high surgical risk].

The hemodynamics was intraoperatively studied in 43 patients with multicentric atherosclerosis, ASA III-IV, operated on the peripheral vessels of legs with balanced anesthesia based on subarachnoid block. It was established in regional sympathetic block and in the course of the whole surgery that the parameter of AP were decreased by 20-25%, those of heart rate--by 15% and of TPVR--50%, whereas, the parameters of cardiac performance were stable. The authors discuss the specificity of hemodynamic restructuring under subarachnoid block in patients with at surgical risk due to vascular pathology.
