[Various characteristics of hemodynamics in pelvic injuries associated with cranio-cerebral trauma]. / Nekotorye osobennosti gemodinamiki pri povrezhdeniiakh taza, sochetannykh s cherepno-mozgovoi travmoi.

The authors have analysed the results of the treatment of 325 patients with injuries of the pelvis associated with cerebrocranial trauma. It has been determined that the severity of the condition and the occurrence of shock depended not only on the character of the pelvis injuries, but also on the severity of the brain injuries. The investigation of the circulating blood volume in 92 victims (pelvis injuries were associated with light brain injuries in 59 cases and with severe brain injuries in 33 cases) has demonstrated that severe cerebrocranial trauma associated with similar injuries of the pelvis influences the circulating blood volume deficit. The arterial pressure and the systolic rate correlate with the circulating blood volume deficit with the exception of the cases of gross truncal disorders with the circulating blood volume deficit reaching 30% and more above the normal values.

Hemodynamic disorders were studied in 60 patients with isolated craniocerebral injury and in 145 patients with craniocerebral injury and injury to the locomotor apparatus. The authors studied the changes in the mean dynamic arterial pressure, the cardiac contraction rate, the cardiac output, the general peripheral vascular resistance to blood flow, and the circulation volume. It was found that in isolated craniocerebral injury the circulation volume deficiency does not exceed 13%, the mean dynamic arterial pressure and the cardiac output increase. In cases of craniocerebral injury combined with injury to the locomotor apparatus the required level of the mean dynamic arterial pressure is maintained by a higher cardiac output and an increase in the general peripheral vascular resistance to the blood flow. The changes in hemodynamic indices including the circulating volume deficiency depend on the degree of injury to the locomotor apparatus and of craniocerebral injury.
