Tagesschwankungen von Blutdruck und Herzfrequenz bei Patienten mit zerebraler Hypoxie bei Aufnahme und Entlassung

摘要

Hypoxie brain injuries are severe consequences of cardiac and pulmonary events requiring resuscitation, trauma, massive bloodloss or suicide attempts. The circadian course of body temperature, heart rate and blood pressure of 13 patients who were admitted into a neurologic rehabilitation intensive care unit after hypoxie brain injury are analysed retrospectively. Chronograms revealed a loss of diurnal variation of the investigated parameters (ANOVA). Particularly, the increase of heart rate and blood pressure during morning hours could not be verified. The results can be explained by damage of oscillatory neurons in the diencephalon and the medulla oblongata as a consequence of cerebral hypoxia.
