Be careful to prevent catching fire during use of laser
- During use of laser, stop anesthesia gas and spread the accumulated gas by a fan.
- Use muscle injection like ketamine instead of anesthesia.
- Protect inflammable items like trachea tube with a wet gauze.
- Make sure to fit the mask and the head firmly to prevent gas leakage.
