[Functional reserves of blood circulation in aged patients].
Central hemodynamics (CH) were studied in 43 elderly (72.4 years) patients by means of the Swan-Ganz catheter. Analysis according to three main criteria--the clinical picture and the values of volume blood flow and jamming pressure in the pulmonary artery--disclosed several hemodynamic types. The "hypovolemic" CH variant was prevalent (17), the eukinetic type of CH was encountered in 8, the "hyperkinetic" type--in 7, and the "hypokinetic" type--in 2 patients. Some parameters of the system of oxygen transport were used as additional information. Patients with limited reserves of circulation were set apart. Additional preoperative management for correcting CH disorders was recommended for them. It is concluded that the approach to the appraisal of the condition and reserves of circulation in the elderly must be more scrupulous.
