Abstrakt: Objective: Aim: To assess changes of blood pressure and central hemodynamic in children with acute respiratory diseases.
Patients and Methods: Materials and Methods: A total of 40 children aged 10-12 years with community acquired pneumonia and acute bronchitis in the period of early recovery were enrolled in the study with data comparing with control group of 30 healthy children. The hemodynamic parameters included blood pressure and calculation of systolic and minute blood output volumes.
Results: Results: In children with respiratory diseases a significant decrease in systolic, pulse and average dynamic blood pressure with a slight difference in diastolic pressure were registered. This may indicate the phenomena of diastolic dysfunction due to increase of pulmonary blood flow resistance and deterioration the process of the left heart ventricles filling in diastole. Average dynamic blood pressure was significantly lower in children with respiratory diseases compared with control group: in patients with pneumonia (mean ± standard error of mean) - 76,1±2,1 mm Hg, with bronchitis - 77,1±1,4 mm Hg, in healthy individuals 82,1±1,6 mm Hg (p<0,05). The analysis of cardiac output indicators showed in children with respiratory diseases a decrease in stroke volume but in the same time, the indicator of minute blood output volumes was compensated by higher heart rate without significant difference between the groups.
Conclusion: Conclusions: The hemodynamic reduction in children with acute respiratory pathology could be caused by diastolic dysfunction and disorders of autonomic regulation.
