Abstract:
Objective
To observe the changes of sublingual collaterals in children with lobar pneumonia and their correlation with tongue texture and tongue coating.
Methods
From March 2018 to March 2019, 206 children with lobar pneumonia and 100 children with bronchial pneumonia were treated in the Department of Pediatrics, the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine, who were included in the study as lobar pneumonia group and bronchial pneumonia group. A total of 100 health children were chose as the normal control group. The abnormal distribution of sublingual collaterals was compared and analyzed among the three groups. Meanwhile, the tongue texture and tongue coating of children with lobar pneumonia were observed to analyze the correlation.
Results
The abnormality rate of sublingual collaterals was 61.7% in lobar pneumonia group, which was significantly higher than that in bronchopneumonia group and normal control group, and the difference was statistically significant(P＜0.05). The abnormal sublingual collaterals in lobar pneumonia children were shown as red purple tongue and thick and greasy tongue coating.
Conclusion
The sublingual collaterals play a significant role in the diagnosis of the blood stasis sign in children with lobar pneumonia, and is a necessary supplement to tongue texture and tongue coating, which can further guide clinical practice.
