Frequently Asked Questions Regarding N2O/O2 Sedation
1. Can I use oral premedication with N2O/O2?
Yes, but there will be a synergistic effect between the N2O and other drugs. Therefore, it is important to know the pharmacology of all the drugs involved. You are responsible for all the drugs you administer, and you must be prepared to rescue a patient from the next level of sedation beyond that which was intended.
2. Is it okay to eat before receiving N2O and O2?
Yes, a light, nonfatty meal eaten no closer than 2 hours before the procedure is fine. It is best to avoid heavy meals.
3. Are there any latex-free products available?
Yes, all currently manufactured products are latex-free.
4. Is a pulse oximeter necessary for N2O/O2 sedation?
No, not if it is given in concentrations less than 50%. At concentrations greater than 50%, it is recommended to monitor the patient with a pulse oximeter, because these concentrations result in the level of moderate sedation.
5. Is sickle cell anemia a contraindication to N2O/O2 use?
No. In fact, preventive measures for sickle cell crisis use 100% O2.
6. Does the conduction tubing need to be sterilized after each patient?
Any part of the tubing that is not corrugated can be sterilized. This can be done after each patient, but it is not necessary. Surface disinfection is adequate.
7. How does N2O affect the lactating (nursing) mother?
N2O has no effect on breast milk.
8. Can N2O/O2 enhance difficult venipuncture?
Yes, a short course of N2O/O2 can enhance venous distention and visibility.
9. Can I return to work immediately after I have used nitrous oxide and oxygen for a medical/dental procedure?
Yes, as long as you feel like your normal self. Some people feel tired or very relaxed following sedation, especially if they were very anxious before a procedure. The standard of care is to administer a minimum of 5 minutes of postoperative oxygen and some people need additional time. The person administering the drug is responsible for assessing the recovery of the patient and will recommend an escort when necessary.
10. Can I use nitrous oxide without oxygen?
No, the O2 molecule must be available for human metabolism. The use of N2O without O2 could result in death.
11. What is the youngest age in which N2O/O2 sedation can be administered?
N2O/O2 sedation can be used for patients of any age.
12. Does insurance pay for N2O/O2 sedation?
Yes, some companies reimburse for this service, although others do not. In the United States, the ADA reimbursement code is #09230.
13. Can a person with asthma use N2O/O2 sedation?
Absolutely; asthmatics respond very well to N2O. Keeping a patient with asthma from getting anxious is impo/>
