Abstract

A foreign body in the respiratory tract is one of the common accidental injuries of children in our country, and is usually an important and serious event. Injuries caused by foreign substances in the respiratory tract seriously threaten the health and life of children in Korea and are a great challenge for parents as well. In the process of diagnosis of foreign bodies in the respiratory tract, there is often missed diagnosis or serious complications. Therefore, this article proposes the application of 64-slice spiral CT imaging technology based on smart medical augmented reality in the diagnosis of foreign bodies in the respiratory tract in order to improve the diagnosis of foreign bodies in the respiratory tract, provide help with treatment to improve the prognosis of foreign bodies in the respiratory tract, and reduce the incidence of foreign bodies in the respiratory tract. In this paper, 36 children underwent a 64-slice spiral CT scan of their lungs, and images were transferred to a workstation for multiplanar reconstruction, minimal density projection, three-dimensional volume reconstruction imaging, and CT virtual endoscopic reconstruction, the location, shape, size, and size of the foreign body in contrast with adjacent structural lesions and lesions seen during surgery. Experiments have shown that the left bronchial granulation accounted for 27.3%, the right bronchial granulation 18.75%, the main tracheal granulation 28.6%; there was no significant difference between the left and right bronchial granulation (P > 0.05), while the main tracheal granulation and bilateral bronchial granulation there are significant differences between the shape distributions (P < 0.05). This shows that CT imaging technology has enabled more patients to avoid surgical operations and ensure that the spiral computer can bring the greatest benefits to children. A 64-slice spiral CT scan can diagnose foreign bodies in the child's respiratory tract. The detection rate is high and the diagnostic failure rate is low. The diagnostic rationale provides a reference for early clinical treatment.

Highlights

A respiratory foreign body is a common critical illness in the otolaryngology department
All images were diagnosed and evaluated by three doctors in the CT imaging room using the double-blind method, and the final diagnosis was obtained by synthesizing the diagnosis results. e number of cases was calculated based on whether a foreign body in the respiratory tract could be clearly diagnosed. e diagnostic criterion for CT films is that the image quality is clear and the bone structure of the larynx is clearly displayed, which does not affect CT diagnosis
Suspicious foreign body in broad bean husk trachea (c) granulation 18.75%, the main tracheal granulation 28.6%, there was no significant difference between the left and right bronchial granulation (P > 0.05), while in the main tracheal granulation there is a significant difference in the distribution of bilateral bronchial granulation shape (P < 0.05), indicating that the formation of granulation is obviously related to the airflow velocity and the location of the foreign body. e foreign body is not easy to form intratracheal granulation in the position where the airflow is not easy to stay

Summary

Introduction

A respiratory foreign body is a common critical illness in the otolaryngology department It is more common in children under 5 years old and occasionally in adults. Kasemsiri et al believe that the inhalation of foreign bodies in children will cause great pain to children, and the more serious ones may even be life-threatening. He proposed that CT imaging technology can reduce the chance of misdiagnosis or missed diagnosis when diagnosing foreign bodies in the respiratory tract so that more children can be as early as possible and accurately diagnose the foreign body in the respiratory tract [3]. Egorov and Mustafaev and others conducted a questionnaire survey on 1490 mothers of children under the age of 2 to learn their understanding of nut-like respiratory foreign bodies, which proved that parents generally lack the awareness of preventing accidental injury of children’s respiratory foreign bodies [4]
