[Peculiarities of anesthesia and systemic hemodynamics in experiment with 30 days head-down immobilization of monkeys].

Two series of surgery (biopsy) were performed before and after 30-d head-down immobilization (HDI) of monkeys. The animals were anaesthetized by inhaled isoflurane. Effects of immobilization on systemic hemodynamics and the progress of anesthesia were evaluated. The experiment showed that HDI reduces systemic arterial pressure and slightly increases heart rate (HR) irrespective of the use of anesthesia. However, comparison of systemic hemodynamics parameters before and after the 30-d immobilization also revealed a drop in systemic arterial pressure, both systolic and, to a less degree, diastolic but not a significant rise in HR during the second surgical operation.
