[The state of autonomic homeostasis during the use of a low-intensity helium-neon laser as a component of combined anesthesia]. / Sostoianie vegetativnogo gomeostaza pri ispol'zovanii nizkointensivnogo gelii-neonovogo lazera kak komponenta kombinirovannoi anestezii.

The effect of intravenous blood irradiation, using helium-neon laser, on vegetative homeostasis during surgery was studied. It has been established that the introduction of low-intensity laser blood irradiation into a complex of anesthesiologic procedures ensures a more effective protection of patients from the surgical stress.

[Psychotropic therapy during anesthesia in the treatment of burn patients at various stages of the disease]. / Psikhotropnaia terapiia pri anesteziologicheskom obespechenii lecheniia obozhzhennykh na razlichnykh étapakh ozhogovoi bolezni.

The efficacy of various types of psychotropic therapy was comparatively assessed in patients with burns and borderline neuro-psychic disorders. The efficacy of therapy was determined using standard uniform scales for the evaluation of the effect of psychotropic agents and by analysis of statistical indexes of the heart rhythm and respiratory pattern. Psychotropic therapy significantly reduced psychopathological symptoms and a more marked normalization of autonomous body functions was observed. It has been concluded that the most effective type of psychotropic therapy in patients with burns and borderline neuro-psychic disorders is combined use of phenazepam and amitriptyline.

[Interrelation of respiratory variability and ventilatory sensitivity to a hypercapnic stimulus]. / Vzaimosviaz' mezhdu variabel'nost'iu dykhaniia i ventiliatornoi chuvstvitel'nost'iu k giperkapnicheskomu stimulu.

Breathing variability and ventilatory response to carbon dioxide (SCO2) were studied after premedication with moradol, in healthy subjects and those with acute pain syndrome. Inverse relationship between SCO2 and breathing variability was established. SCO2 was the highest in the group of patients with acute pain syndrome and the lowest in patients after premedication with moradol.

[Evaluation of the principles of distribution of electrocardiographic R-R intervals for elaboration of methods of automated diagnosis of cardiac rhythm disorders]. / Issledovanie zakonomernostei raspredeleniia intervalov R-R EKG dlia razrabotki sposobov avtomaticheskoi diagnostiki narushenii ritma serdtsa.

A statistical analysis of prolonged ECG records has been carried out in patients with various heart rhythm and conductivity disorders. The distribution of absolute R-R duration values and relationships between adjacent intervals have been examined. A two-step algorithm has been constructed that excludes anomalous and "suspicious" intervals from a sample of consecutively recorded R-R intervals, until only the intervals between contractions of veritably sinus origin remain in the sample. The algorithm has been developed into a programme for microcomputer Electronica NC-80. It operates reliably even in cases of complex combined rhythm and conductivity disorders.

[Automatic recognition of RR-intervals of sinus origin from real electrocardiographic signals]. / Avtomaticheskoe vydelenie RR-intervalov sinusovogo proiskhozhdeniia iz real'nogo élektrokardiosignala.

A simple decisive rule for classifying RR-intervals of electrocardiograms by two types, sinusoidal and anomalous, is deduced using the theory of pattern recognition. Parameters of the decisive rule according to the minimum of the Buyess probability of the classification error are selected. The algorithm may be realized with microprocessors and used in cardiac rhythm monitors.
