[Effect of hyperbaric oxygenation on the clinical course and complications of the acute period of ischemic strokes].

Hyperbaric oxygenation (HBO) was included in the therapeutic complex for 124 patients in the acute stage of ischemic stroke. The effect of HBO on the clinical course was appraised by comparing the dynamics of changes in the clinical symptoms and the frequency of complications in patients exposed to HBO with those in the control group (patients not exposed to HBO). It was established that the depth of unconsciousness and the motor and aphasic disorders decreased during a HBO session, but the effect was usually short-lived. Aggravation of the patients' condition in the first week of the disease, evidently caused by increase of cerebral edema, occurred much less frequently when HBO was included in the complex of therapeutic measures. The number of patients with regression of the neurological symptoms was practically the same with and without the use of HBO, but the regression of the neurological defects was most evident in patients exposed to HBO. HBO prevents the development of recurrent cerebral circulatory disorders in the acute stage of ischemic stroke and reduces the incidence of some complications in this period (pneumonia, pulmonary edema, thromboembolism of the pulmonary artery, etc.).

[Effect of hyperbaric oxygenation on respiration in acute cerebral circulatory disorders].

The OKA-MT pressure chambers were used. External respiration was studied by spirography by means of the SG-2M spirograph. From the results of examination of 53 patients with acute cerebral circulatory disorders it was established that hyperbaric oxygen normalizes the initially abnormal external respiration: corrects the periodical rhythms and reduces hyperventilation; the hyperbaric oxygenation sessions have no effect on initially normal respiration; the reaction of external respiration to hyperbaric oxygen changes during the course of treatment depending on the number of sessions; the appearance or intensification of the hyperventilation syndrome after one or three hyperbaric oxygenation sessions in the absence of negative neurological dynamics cannot be assessed as a contraindication for hyperbarotherapy.

[Use of hyperbaric oxygenation in various complications of craniocerebral injury in the acute period].

As the result of examination of 92 patients with acute craniocerebral trauma it was established that the use of HBO in the complex of therapeutic measures is permissible after removal of an intracranial hematoma despite occasional convulsive paroxysms, if there is no history of epilepsy. Exposure to HBO does not intensify or cause a recurrence of bleeding in traumatic subarachnoid hemorrhage and after operation for intracranial hematomas and brain contusion. Exposure to HBO does not cause an effect on the intensity of liquorrhea in the patients and does not lead to pneumocephalus or infection of the subarachnoid space.

[Effect of hyperbaric oxygenation on central hemodynamics in patients in the acute stage of ischemic stroke].

Thirty-two patients with ischemic stroke of various localization were examined. The method of tetropolar rheography was used; 300 tetrapolar rheograms were recorded. The patients were examined before, immediately after, and 2--3 hours after the hyperbaric oxygenation session; the haemodynamics were studied several times during the course. On the grounds of the study carried out, the authors conclude that in most patients the first HBO sessions cause a general vasoconstricting effect and lead to a decrease in the cardiac output; the next sessions normalize the initially abnormal hemodynamics; the HBO sessions hardly cause any changes in arterial pressure, in patients with vertebrobasilar pathology, however, a mild elevation of systolic and mean pressure was recorded after the sessions; hyperbaric oxygen reduces the rate of cardiac contractions by 9% irrespective of the initial pulse rate.

[Characteristics of the process of brain stem compression in the acute period of cranio-cerebral injury].

Proceeding from an analysis of 520 cases of surgery for acute and subacute intracranial haematomas, the author concludes that the process of brain compression is characterized by the tempo, degree and duration that are interrelated. A slow tempo of compression may bring about a significant degree and duration of the compression, with the compression-dislocation syndrome being rather indistinct, which is not observed in cases of a fast tempo. The degree of compression is determined not only by the size of the haematoma, but also by the severity of the contusion and oedema of the brain, by the size of the reserve intracranial spaces, etc. The duration of an acutely developing significant brain compression is a decisive factor in the success of a surgical management of a haematoma. The severity of brain contusion affects various aspects of the compression process--its tempo, degree, and --indirectly--duration.
