in neck or nasopharynx surgery if netrous oxide is used
Why are only moist sponges utilized during electrocautery use
to prevent fire
If the electrocautery is used through the colonoscope, carbon dioxide should be available to flush out the colon because
gases normally in the colon could cause an explosion
