Abstract:
Objective
To investigate the risk factors of acute respiratory dysfunction in children with respiratory foreign bodies before operation.
Methods
A total of 100 children with respiratory foreign bodies and respiratory dysfunction were included as the research subjects(the observation group), who received treatment in Hunan Children's Hospital from Jan. 2011 to Dec. 2016. Another 100 children with respiratory foreign bodies but without respiratory dysfunction receiving treatment during the same period of time were chosen as the control group. Their clinical data were collected, and the risk factors of acute respiratory dysfunction were analyzed by single-factor and Logistic multi-factor regression analysis.
Results
Pneumonia, fever and mediastinal subcutaneous pneumatosis were the main risk factors based on the singlefactor and Logistic multi-factor regression analysis.
Conclusion
Pneumonia, fever and mediastinal subcutaneous pneumatosis are the main risk factors of acute respiratory dysfunction in children with respiratory foreign bodies before operation. Therefore, in the clinical treatment, the preventive strategies should be made according to the disease state and the risk factors of the children in order to reduce incidence of acute respiratory dysfunction before operation in children with respiratory foreign bodies.
