Whenever the operating theatre is mentioned, there will always be a feeling of coldness, as if stepping into a freezing cold place. This makes many people feel confused: operating theatre is really so cold? What are the reasons for this? Today we will reveal the real reason why operating theatres are kept cold.

I. Maintaining a clean environment to ensure patient safety
Low temperature can effectively inhibit the growth of bacterial flora, reduce the risk of surgery and the possibility of infection, to protect the patient's surgical safety. At the same time, low temperature can also delay the oxidation and corrosion of instruments, extend their service life, and improve surgical results.    

Reduce surgical risks and improve surgical success rate
The surgical process requires highly focused and precise operation by the entire medical team, which in turn shortens the length of surgery and recovery time for patients. The high temperature environment will produce sleepiness, sweat and other discomforts, affecting the concentration and precision of medical staff.

Third, to ensure the stability of equipment performance, to extend the service life
High-tech equipment used in the operating theatre, such as surgical lights, monitors, electric knives, etc., will generate heat when in use, in order to extend their service life and ensure the normal operation of the equipment, it is necessary to maintain a suitable low-temperature environment.    

Fourth, what methods are used to reduce the problem of cold patients?
1. Operating theatre nurses introduce the operating theatre environment to patients during pre-operative visits and provide psychological care and support.
2. To ensure patient comfort and safety, the temperature and humidity are adjusted in advance on the day of surgery, with the temperature generally controlled at 21-25°C and the humidity set between 30% and 60%. In addition, the exposed parts of the patient's skin are kept warm to enhance the patient's comfort.    
3. If necessary, choose the appropriate heating equipment to maintain the patient's body temperature. For the rinsing solution that needs to be used during the procedure, we will put it into the thermostat in advance for warming.
Finally, we hope that through our joint efforts, we can provide a warm space for patients and thus establish a comfortable surgical environment.
