Behind The Scenes "War Epidemic": People Closest To The Virus

In February 11th, the Concord Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology issued a notice calling for the transformation of the Concord Hospital Cancer Center into a designated hospital for the treatment of new crown pneumonia patients. On the same day, the laboratory of the cancer center of Xiehe Hospital was rebuilt immediately, and the patient was treated the next day.

"At that time, I felt that the epidemic was more severe and the demand for hospitalization was larger. At that time, the work of the shelter hospital, Raytheon Hill Hospital and other hospitals were strained, and the bed was once tight. Wang Hui, director of the laboratory of Concord cancer center, told the twenty-first Century business reporter.

Hard adaptation

Since the cancer center of Xiehe Hospital is a tumor specialist hospital, in order to meet the testing needs, the nucleic acid detection part was arranged in the laboratory of the Concord division. After receiving throat swabs, doctors and nurses send them to the Cancer Center Laboratory for registration. Then they are sent to the molecular biology laboratory of the Concordia department for testing with special vehicle personnel, and the final results are reported to each ward.

The cancer center laboratory has been more than half a month since its renovation and now basically meets the detection of new crown pneumonia patients. But in fact, at the beginning of the transformation, the adaptation process of medical staff was not easy.

"Compared with the daily work, the biggest difficulty of inspection is that the inspection items are different from the original ones, and some new devices need to be introduced, for example, the blood gas analyzer is temporarily deployed." Wang Hui said, before the Department of laboratory work mainly targeted at cancer patients, tumor markers, liver function and renal function after radiotherapy and chemotherapy, or patients with myelosuppression have more blood routine. Nowadays, patients with respiratory diseases, pulmonary infection and hypoxic pulmonary failure are mainly pathogenic detection and immunological detection.

After the new instrument was put in place, to ensure the smooth progress of the inspection work, Wang Hui led the team of 15 people to start the day work and study in the evening. In the case of sufficient time, engineers and technical support of instrument manufacturers should be trained and trained. But the time is not allowed and the laboratory is not convenient for trainers to come. After weighing, let the other side pass the training video, and watch and learn at night, so that the instrument can operate normally.

The detection work plays a vital role in the diagnosis and treatment of new crown pneumonia. In order to ensure the timeliness and accuracy of the test, the laboratory should carry out the inspection of all kinds of specimens for 24 hours. Wang Hui introduced to reporters: "most of the hospitalized patients take blood at six a.m., and the time for specimens to the clinical laboratory is usually at half past seven. In order to ensure that the patients get the results in time, the laboratory department takes the morning to noon system to make the patient's specimen as soon as possible, which is the largest amount of work done in the laboratory."

In the process, another issue which is particularly worrying is protection. Because the Wang Hui team is one of the first-line departments directly contacting the source of infection, protection work is particularly important, and their hospital knowledge and skills are the important source of confidence in effective protection. "According to the arrangement and arrangement of the hospital sense office, the departments were re divided into pollution areas, potential pollution areas and clean areas. In addition, before going to work, it is required to spray the medical alcohol on the surface of the instrument, the surface of the test bench, the keyboard and the mouse. In the afternoon and evening, some time will be devoted to ultraviolet disinfection of the laboratory. "

It is worth noting that because the test tube of blood samples taken by patients is negative pressure test tube, some tests need to be centrifuged and covered. In the process of opening, the infection rate of medical staff in the laboratory will be increased.

For this reason, Wang Hui repeatedly urged team members to observe the specimens: "first, disinfecting the internal parts of centrifuges; second, when opening the lid, it is required to open lightly and remain in the state of not fully open for a few seconds, so that the internal pressure and external pressure can reach the same level. Then the lid is opened and placed for 20 minutes. Third, when testing specimens, reduce repeated oxygen inhalation. In order to reduce the risk of aerosol infection.

Providing data support

Many of the new crown pneumonia patients admitted to the cancer center are critically ill or even critically ill. Wang Hui said: "patients with diabetes, hypertension, heart disease, brain diseases, and even cancer have all, so every patient's treatment is mainly against the new crown virus, but drugs for treating these diseases should also be used at the same time."

Due to the large number of middle-aged and elderly patients in this group, which are accompanied by underlying diseases, doctors in various departments have formed good cooperation in the treatment process, including endocrinology experts, digestive experts, Department of nephropathy experts, and even some experts in liver diseases, as well as experts in cerebrovascular and tumor specialties.

To this end, the laboratory as the first pass of patient specimen collection, has played a role in "gatekeeper", providing data support for clinicians' precise diagnosis and treatment. Wang Hui gave an example: "some of the older patients with new crown pneumonia have diabetes. When they are doing biochemical tests, the blood sugar is high. Specialists will guide doctors who are treating new crown pneumonia, and how much blood sugar can be used to reduce the blood sugar level of the patients. All these need to be supported by the data provided by the laboratory."

On the other hand, the nucleic acid test of the new crown virus is of great importance for the diagnosis of the disease. Therefore, the accuracy of the test has become the focus of attention. In addition, test method differences, project detection systems and individual differences also increased the difficulty of testing.

In this regard, Wang Hui told reporters, "the results of an experiment to accurately reflect the patient's condition, inspection work is divided into pre experiment, experiment and quality control after the experiment. The most important influence on the test results is the quality control before the experiment. Taking sample as an example, the use of nasopharyngeal swabs is especially important for doctors and patients. When patients are doing sputum culture, they need to take sputum from the deep throat, but sometimes the patient may spit saliva directly, thereby affecting the detection results.

In Wang Hui's view, medical laboratory personnel can only control the quality of the experiment and after the experiment. Therefore, they also communicate with clinical doctors and nurses, and cooperate with doctors, nurses and patients to ensure the accuracy of sampling.

Since receiving the task of being admitted to the hospital, Wang Hui has the greatest feeling: "now I feel that every age group has a backbone and knows the burden on his shoulders. No matter after 70, like my age, or after 80, or even after 90, in the face of the epidemic did not shrink back, I think this is very great. When I received the notice, even if there was such difficulty in every family, they were the first time to get to the Department, and I felt very moved.
