ABSTRACT
Preliminary results of intraoperative monitoring of the degree of neuromuscular blockade using a portable device based on the technique of evoked electromyography are presented. The device has an analogue outlet for the connection with a computer. The technique used is simple and reliable and makes it possible to work out a computerized system for automatic graded supply of current myorelaxants on a feedback principle. Such a system does not only ensure an adequate level of myorelaxation with a minimum expenditure of expensive drugs, but also gives a new approach to the study of neuromuscular conduction during anesthesiological supply in various surgical interventions.

The design and clinical applications of the first Soviet syringe portable insulin pump Electronica UV1 01 N are described. The technical characteristics and functional possibilities of the pump are discussed. The clinical results demonstrate good compensation for glucose metabolism by the insulin pump Electronica UV1 01 N.

During the recent years various investigators have developed the technique of kryophotometric measurements of oxyhemoglobin saturation with oxygen (psi) in small vessels. In this paper, on the basis of the statistical model of the organ developed by the authors, a theoretical relationship is established between the distributions of measured in various groups of experiments in the capillaries and the distributions of psi in the arterioles and venules. It is shown that for the description of the distribution of psi in a separate multicapillary unit, lying between the arteriole and the venule, it is possible to introduce a special distribution function. In some cases this function may be determined analytically. Statistical distributions of other microcirculation parameters may be included into the statistical model of the organ using the similar procedure described in this paper for the parameters psi a' psi v- arteriolar and venular psi.
