The dangers of operating room smoke

Odor: The smoke contains about 600 kinds of chemicals, and there is no shortage of toxic substances and carcinogenic ingredients

Studies have found that harmful chemicals have been detected in surgical smoke, such as: hydrocyanide, benzenes, hydrocarbons, oxycarbons, aldehydes, phenols, fatty acids, etc .;

Particles: Experimental CO2 laser vaporizes tissues. 77% of the particles are smaller than 1.1 μm, but the diameter of the surgical mask is 5 μm. Particles can easily pass through the mask, causing chronic irritation, bronchitis, etc

Many studies have shown that surgical smoke particles are small and should not be inhaled. Repeated inhalation will cause changes in the respiratory tract, leading to acute and chronic respiratory diseases;

Microorganisms: Inhaled particulate matter may carry microorganisms, although not fully confirmed, but experimental support

Experiment: CO2 laser was used to treat infected pigskin, and there were live bacteria in the smoke;

Concerns about endoscopic surgery

For many years, people thought that nausea and vomiting in laparoscopic surgery were the cause of anaesthetic gas, but research shows that the possibility of surgical smoke is high

Experiment: Compare the harm of smoke and cigarette;

CO2 laser was used to cut 1 gram of tissue and collect smoke, and found that its potential harm was the same as that of 3 unfiltered cigarettes;

If an electric knife is used for the experiment, the harm is equivalent to 6 unfiltered cigarettes;

Conclusion: The smoke generated by electrosurgery is twice as hazardous as the laser.
