[Relation between the status of central hemodynamics in the monkey in the postoperative period and the conditions of its maintenance prior to the surgical procedure]. / Sostoianie tsentral'noi gemodinamiki u obez'ian v posleoperatsionnyi period v zavisimosti ot uslovii soderzhaniia ikh do operativnogo vmeshatel'stva.

The pumping and contractile cardiac function of monkeys was examined at different time intervals after electrode and transducer implantation. The study was carried out using 26 rhesus monkeys under ketalar anesthesia. The effect this surgical intervention on intracardiac hemodynamics depended on the initial health state of the animals. Prior to operation the pumping function declined due to diminished motor activity of the animals. It remained decreased to a greater extent 10-15 days after operation. When normal motor activity was allowed even for a short time before surgical implantation, this was sufficient for the normalization of the cardiovascular function. In view of these observations, we should be very cautious to expose monkeys to diminished motor activity for long periods of time.
