[The volume of circulating blood during surgery of the aorta performed under epidural anesthesia].
Various methods of circulating blood volume (CBV) determination have been compared. The calculation method based on anthropometric to hemodynamic parameter ratio was shown to be optimal during surgery on the aorta and major vessels. Epidural anesthesia in 15% CBV deficit in the preoperative period and anesthetic administration into the epidural space intraoperatively in 10% CBV deficit were contraindicated. Epidural anesthesia caused CBV reduction, with its maximum changes observed upon blood flow recovery in the vascular bed. 10-15 ml/kg, 15-20 ml/kg and 20-30 ml/kg blood loss was 2.5,3 and 3.5 times overcompensated, respectively.
