[General anesthesia using diprivan in patients with lesions of the locomotor system in a day hospital].
The study is aimed at investigating the possibility of using diprivan in total anesthesia of patients with consequences of infantile cerebral paralysis (ICP) during orthopedic surgery in an outpatient setting. The study was carried out at the Institute of Clinical Rehabilitology in the town of Tula. Ninety-two patients aged 4 to 15 years were examined. Hemodynamics was assessed by tetrapolar thoracic rheography after Kubecik. The patients were divided into 3 groups with disorders of static kinetic functions of different severity: I) walk-in patients, 29.3%; II) patients walking with difficulty, 59.7; III) patients incapable to walk by themselves, 9.2%. The autonomic status was studied using clino-orthostatic tests and cardiointervalography. Characteristic changes of the hemodynamics under conditions of narcosis and surgery were revealed in the patients with locomotor disorders of different severity. Diprivan can be used as the basic hypnotic component of anesthesia in orthopedic operations in patients with ICP consequences with locomotor disorders of different severity. It meets the requirements to the adequacy of anesthesiological protection in an outpatient setting. Assessment of the autonomic status in patients with ICP consequences permits a differentiated approach to total anesthesia with diprivan. Premedication with ketamine prevents the hypotensive effect of diprivan and ensures hemodynamic stability in the course of anesthesia and surgery.

[Central hemodynamic changes in children with locomotor system diseases during surgery and anesthesia].
Various neurovegetative reactions and disorders of circulation are observed in children with consequences of infantile cerebral paralysis (ICP). The manifestation of these reactions depends on the severity of motor disorders and the local painful syndrome. This study was aimed at detecting the changes in the central hemodynamics and development of measures preventing these changes during narcosis in patients with orthopedic consequences of ICP subjected to surgical treatment in an outpatient setting. In addition, we studied the possibility of wide use of calypsol in this category of patients in a one-day hospital. Autonomic reactivity was studied by cardiointervalography after Baevskiĭ. The stroke and minute volume were assessed by tetrapolar thoracic rheography after Kubecik. A total of 120 patients aged 7-14 years with ICP consequences were divided into 3 groups with motor disorders of different severity. Examinations during preparation to narcosis and narcosis revealed a relationship between autonomic and hemodynamic disorders and the severity of motor disorders. An optimal method for preventing hemodynamic changes associated with narcosis in an outpatient setting is proposed.
