[Changes in the intracranial pressure in relation to body posture and their use in the treatment of patients after cranio-cerebral injuries].

The determination of the best body position in patients after cranio-cerebral injuries was the main subject of the undertaken studies. This optimal body position should ensure the intracranial pressure drop on condition that the cerebral blood flow and cerebral elasticity are not disturbed. To accomplish this task a biophysical model of the positional changes of the cerebro-spinal fluid pressure was elaborated. I took the activity of the gravitation and adhesive forces as well as contraction phenomenon into consideration, while preparing the model. The verification of the biophysical model was carried out by clinical examination of 15 patients, which confirmed its correctness. The positional changes of the intracranial pressure and cerebral perfusion pressure as well as cerebral elasticity were analyzed in 11 patients after cranio-cerebral injuries. I disclosed the intracranial pressure normalization and cerebral blood flow improvement by elevation of the body to the position of 30 degrees. Moreover, it appears that the shift of the cerebral midline structures causes an essential diminution of the positional intracranial pressure drop by the body elevation. The retrospective studies in 157 patients after cranio-cerebral injuries permitted me to compare the results of the classical treatment and the positioning one. I have ascertained that the applying of the trunk and head elevation to the position of 30 degrees improves the results of the medical treatment.
