The risks of intravenous sedation are minimal. There are risks that may occur: becoming too sleepy, being unconscious, depressed breathing, awareness or discomfort, aspiration, low blood pressure, and allergic reaction.
 
What if sedation is not used?
If the patient does not want sedation, they must discuss this with the doctor to understand the risks associated and other appropriate options.
