[Mechanics of circulation in lowering the blood pressure in different hemodynamic forms of hypertension (author's transl)].

The high blood pressure of essential hypertension sustained by an increased peripheral resistance or by cardiac output, or by both of these magnitudes. To examine the mechanics of lowering the blood pressure in these different forms of hypertension on analysis of circulation was carried out on three patients with a cardiac output hypertension and on seven patients with a resistance hypertension before and after lowering the blood pressure by the compound preparation Briserin. The results showed that the influence on the hemodynamics was different. The therapeutic result was due partly to a decrease of the cardiac output and partly to a reduction in vascular peripheral resistance. The increased parameter of circulation decreased during the treatment. Occasionally however the cardiac output as well as the peripheral resistance were decreased or while one of the parameters decreased the other even increased.

Artificial ventilation and prognostic factors in bacterial meningitis.

The use of artificial ventilation in patients with bacterial meningitis was increased from 8.0% of 176 patients admitted in 1966-1968 to 31.5% of 162 patients admitted in 1975-1976. The therapeutic regimen was otherwise unchanged. The fatality rate decreased from 14.2% in the first period to 8.6% in the second, whereas the rate of neurological sequelae increased from 11.3% to 16.9%. A linear logistic model analysis was applied to correct for the influence of factors of known prognostic importance in the two periods, e. g. age, level of consciousness at admission, mode of admission and etiology. The analysis showed a significant 50% reduction in fatality rate (p = 0.05), whereas the corrected rate of neurological sequelae appeared similar in the two periods. Our results suggest that an increased use of respirator treatment may improve the prognosis in bacterial meningitis.

Mortality in the years following bacterial meningitis.

During the years 1966-1976, 875 patients were treated for bacterial meningitis at the University Clinic for Infectious Diseases, Copenhagen. By about January 1, 1980, all 782 surviving patients had been traced. 87 had died in the observation period of four to 15 years. Mortality in the years following meningitis was studied by means of a comparison with the expected mortality in a matched normal population, using a computer program for the determination of late excess mortality. Late excess mortality was significantly increased during the first two years following discharge after meningitis and was of the same magnitude in the major etiological groups. The cumulative five-year late excess mortality rate was higher in the group of patients between 30 and 60 years, in those transferred from other hospitals, in those in coma or somnolence on admission and in those developing convulsions during hospitalization. In the group of patients aged 30 to 60 years, 11 patients died during the first two years after discharge. In nine of these cases, the main cause or the concomitant causes of death were conditions predisposing to infections or bacterial meningitis. The frequency of the causes of death in the 87 patients who died was not significantly different from that among the general Danish population.
