Abstract
Objective. To improve the results of treatment of comorbid patients with acute arterial ischemia by substantiating the optimal type of spinal anesthesia for surgical intervention on the affected limb.Materials and methods. The study involved 70 patients who were treated in the Department of Vascular Surgery of Clinical Hospital of ‘Russian Railways-Medicine Co.’ in Barnaul. The patients were divided into two groups: group 1 – patients operated under conditions of bilateral (bilateral) spinal anesthesia, group 2 – patients operated under conditions of monolateral (unilateral) spinal anesthesia. All patients underwent an assessment of the level of spinal block on the Bromage scale, monitoring of central hemodynamics using a MARG-10–01 rheograph, postoperative assessment of myocardial ischemia on the ECG, acute kidney damage to control diuresis.Results. In the 2nd group, there was a sufficient sensory and motor block to perform surgery. In the intraoperative period in the group of patients who underwent unilateral blockade, the mean arterial pressure decreased by 3 mm Hg. In this regard, there was no clinically significant increase in heart rate and a decrease in the stroke index and the index of total peripheral vascular resistance. In the 1st group, the decrease in mean arterial pressure reached 20% of the original, which led to an increase in heart rate by 12% and a decrease in stroke index by 11%.Conclusions. During the perioperative period, the indicators of central hemodynamics in the group 2 were more stable compared to the group 1, they did not need the use of vasopressor drugs and crystalloids. And in the early postoperative period, patients who underwent unilateral anesthesia did not show signs of acute kidney injury. Monolateral spinal anesthesia, compared with conventional spinal anesthesia, provides more stable hemodynamics in elderly patients with acute arterial ischemia.
