summary

Sick building syndrome (SBS), also known as sick building syndrome, is proposed by some foreign experts in recent years. Due to air pollution and low air exchange rate in some buildings, people living in the buildings have a series of self-conscious symptoms. After leaving the buildings, the symptoms can subside. This kind of building is called "bad (or sick) building", and a series of symptoms are called "bad building syndrome".

What does bad building syndrome mean?

Attention must be paid to the patient's symptoms, occupational history and environment, including working hours and family environment. Mainly includes: personal basic situation; Symptoms and signs; Description of working process and indoor environment, ventilation, exposure source, dust, humidity, temperature and light, etc; Whether there are any environmental changes, such as new decoration, new equipment, or other relevant changes; Colleagues with the same symptoms and symptoms can be improved after leaving the building are very important for the diagnosis of SBS; It should also include some other factors, such as job satisfaction, job stress, etc.

The diagnosis of SBS is based on the clinical manifestations of the patients, the incidence of group disease among colleagues, the improvement of symptoms after leaving the building, no pathophysiological abnormalities and no clear etiology of similar diagnosis. SBS is not a specific diagnosis, it does not have to exclude all other possibilities before taking measures.

Most of the patients' symptoms often improve rapidly after leaving the corresponding indoor environment. Only a few patients' symptoms still exist after the corresponding environmental quality is improved or they go to other environments. Generally, there is no need for treatment and no known sequelae. Therefore, the psychological burden of patients should be reduced as far as possible.

matters needing attention

Improvement of ventilation system or other intervention measures will not only benefit patients and their colleagues, but also will not cause loss of working time or other losses. The most common mistake is to spend a lot of time, energy and money to find the cause before taking measures to improve air quality. Because in most cases, environmental measurements usually show that the concentration of pollutants is at an acceptable level, it is difficult to clearly point out the pathogenic factors in spite of obvious symptoms.
