Anesthesia, surgical aid and resuscitation in manned space missions.

When discussing problems related to medical service in space flight, particular attention should be given to the specific living conditions and changes associated with space flight. In disease and injury, surgery can be provided only after conservative therapy has failed. In this context gnotobiological chambers allowing surgery in aseptic conditions seem promising. A portable set of interchangeable surgical tools should be made of light-weight alloys that can be readily sterilized. Electroanalgesia in combination with auriculoacupuncture as well as peridureal anesthesia may be used as they allow normal operations in autonomous space flight conditions. Changes in the sympatho-adrenal and kallikrein-kinin systems, as well as water-electrolyte balance, should be taken into account in developing methods and means of medical service in critical situations. Special attention should be given to the prevention and treatment of brain edema in view of weightlessness-induced cephalad fluid shifts.

[Effect of exogenous cardiosynchronized contrapulsation on human regional and central hemodynamics].

Variations in regional and central hemodynamics of man under the influence of exogenous contrapulsation (ECP) were examined rheographically. In recumbent subjects, ECP increased cerebral pulse blood filling, particularly of the vertebrobasilar system. It appears that the significant increase of the tone of arterioles and veins may be important when it becomes necessary to correct cerebral circulation in the situations that may lead to brain ischemia. It has been found that in the orthostatic tilt test ECP can be an effective tool for enhancing brain and lung blood supply and increasing stroke volume, cardiac output and blood pressure. This may help maintain homeostasis and improve orthostatic tolerance. The observation that ECP may facilitate blood supply of the vitally important organs, specifically brain, enables us to recommend this procedure to be used at an early stage of readaptation after simulation or real space flights.

[Problems of anesthesia, surgical care and resuscitation during manned space flights].

When exploring the problems of medical aid to be rendered in manned space flights, it is necessary to take into consideration the specific features of the environment as well as the changes in the human body induced by space flight effects. In space flight anesthesia can be applied using such advanced methods as multi-component balanced anesthesia and peridural anesthesia. Surgery and resuscitation can be performed, employing the procedures and methods that allow operations in an abacterial environment, correction of vital dysfunctions with the aid of artificial pulmonary ventilation, cardiac electrotherapy, and sorptive purification of body fluids. Various aspects of infusion treatment and first medical aid are discussed.

[Principles for making up pharmaceutical kits to supply cosmonauts with drug packs].

Pharmacological, pharmaceutical, clinical, physiological and other aspects of drug supply of cosmonauts are discussed. The procedure of choosing a drug to be included into the medical kit is illustrated by way of a new tranquilizer--a derivative of gamma-aminobutyric acid. The data are presented to describe the contents of the medical kit and their use in the flight of Soyuz-19/Salyut-4.
