The bronchial chilling activity, especially trachea (TBLC or TBCB), plays an important role in the diagnosis of ILD. The following is a detailed description of its application in ILD: First, the challenge of ILD diagnosis is a group of heterosexual diseases with different causes but with similar characteristics in clinical, visual and pathological terms, which are more difficult to diagnose and treat. For the majority of ILD patients, multidisciplinary discussions (MDDs) integrate clinical, laboratory and video data for diagnosis. However, some patients may need to carry out pulmonary tissue pathology assessments to confirm, especially when clinical, video and laboratory data do not provide a sufficient basis for diagnosis. II. The rationale and advantages of a bronchial cooling operation. In the course of the operation, the refrigerated probe is sent to the bronchial or intra-pulmonary pathological area, absorbing the surrounding environment heat through the rapid release of refrigerants, so that the refrigerated probe is cooled and condensed with the tissue surrounding the probe. Frozen sticky force then removes the probe and the surrounding frozen tissue as a whole, thus obtaining the target tissue. A bronchial chiller work test has the following advantages in comparison to the traditional pulmonary activity prosecution method: Small trauma: a bronchial cold work test is a micro-initiative method compared to a surgical pulmonary work test (SLB), with less trauma to patients. Large tissues: The bronchial chiller biopsy provides a larger size of lung tissue specimens compared to the trachea pulmonary biopsy (TBLB) and is of higher quality, which facilitates pathological analysis and diagnosis. There are few complications: there are relatively few, and usually minor, complications from bronchial chiller work. Common complications include haemorrhage, haemorrhagic chest, etc., but the incidence of serious complications is low. The application of bronchial chiller work in ILD The application of bronchial chiller work in ILD is mainly reflected in the diagnosis of the cause of the disease: For patients suspected of ILD, bronchial chiller work can provide a pathological examination of pulmonary tissue specimens, thus identifying the cause of the disease. This is essential for developing targeted treatment programmes. Pathologically confirmed: For patients diagnosed as ILD, bronchial chiller biopsy can further confirm pathological types, facilitate classification and stratification, and provide a basis for the development of treatment programmes. Monitoring of changes in condition: During ILD treatment, bronchial chilling work can be used to monitor changes in condition. By comparing the results of the biopsies at different points in time, it is possible to assess the efficacy of the treatment and the progress of the condition. (b) Pre-operational preparation: the patient needs to perform this examination under the whole body so as to reduce pain and discomfort. At the same time, the necessary equipment and medicines, such as refrigerators, refrigerated probes, air lens intubation, etc., need to be prepared. Operating processes: The vital signs and complications such as haemorrhage, aerobic chest etc. need to be closely observed during the operation. Once an anomaly has been detected, the operation needs to be immediately stopped and addressed accordingly. Paranoia: A number of taboos exist in bronchial cold work tests, such as the presence of regular bronchos to screen for taboos, persons with condensable blood function disorders, persons with severe respiratory failure, etc. For these patients, careful consideration needs to be given to whether to conduct bronchial cooling work. The bronchial chiller biopsy plays an important role in ILD diagnosis, with the advantages of small trauma, high tissue and low complications. As technology progresses and equipment improves, the prospects for its application in ILD diagnostics will be greater. It should be noted, however, that there are still risks and complications associated with bronchial cooling, which need to be performed under the guidance of a specialist physician. At the same time, for different patients and cases, a combination of factors is needed to develop individualized screening programmes. Based on the above, bronchial chiller work provides a new and effective tool for ILD diagnosis, which contributes to the accuracy of ILD diagnosis and treatment.
