Sedation is the use of medications to help your child’s behavior as he/she undergoes needed dental procedures. It will help increase his/her abilty to cope with the procedure and decrease anxiety and discomfort. Below are the the different sedation options that are provided at Union Pediatric Dentistry. Dr. Greenhill or Dr. Jennison will help guide you as to what would be the best options for your child.

Nitrous Oxide

Hygienist working with a child at Union Pediatric DentistrySome children are given nitrous oxide/oxygen, or what you may know as laughing gas, to relax them for their dental treatment. Nitrous oxide/oxygen is a blend of two gases, oxygen and nitrous oxide. Nitrous oxide/oxygen is given through a small breathing mask which is placed over your child’s nose, allowing them to relax, but without putting them to sleep. Your child will be able to pick from different flavors i.e. bubble gum, strawberry, grape, or orange. Another added benefit, is that once treatment is completed, they will be able to take the mask home with them. The American Academy of Pediatric Dentistry, recognizes this technique as a very safe, effective technique to use for treating children’s dental needs. The gas is mild, easily taken, then with normal breathing, it is quickly eliminated from the body. It is non-addictive. While inhaling nitrous oxide/oxygen, your child remains fully conscious and keeps all natural reflexes. It is important to remember that this is one tool in helping your child and is most effective in children that exhibit a mild degree of anxiety and have mild to moderate dental treatment needs.

I.V. Deep Sedation/General Anesthesia

I.V. Sedation is recommended for very apprehensive children and some children with special needs and also have mild to moderate dental treatment needs. Dr. Greenhill or Dr. Jennison will perform the dental treatment in the office with your child anesthetized under I.V. sedation, which is administered and monitored by an anesthesiologist, Dr. Vi Devany. I.V sedation is best suited for those children who have a moderate to high level of anxiety and mild to moderate dental needs.

Information Sheet for I.V. Sedation

Working at Union Pediatric Dentistry serving Florence, Hebron and Burlington, KYIf If Drs. Greenhill or Jennison have recommended dental treatment for your child to be performed using I.V. sedation/general anesthesia with Dr. Devany, the following information will help you in your preparation for the appointment. Dr. Devany is Board Certified in both pediatrics and anesthesiology with 25 years experience in Pediatric Anesthesiology. She will provide anesthesia services for your child while Dr. Greenhill or Dr. Jennison perform the dental procedures. This service is provided at the Union Pediatric Dentistry office in Union, KY.

In order to better care for your child and to maximize safety, Dr. Devany has arranged a protocol as follows:

  1. You have received an information sheet, consent form, pre-op questionnaire and post-op instructions. Do not sign the consent form until you have spoken to Dr. Devany and had all your questions answered.
  2. Dr. Devany or her assistant will call you one to two days before the scheduled time to discuss all the information you have provided, review the plan, risks, and options with you. She will be glad to answer any questions you have.
  3. Some children will be required to have their physician complete a routine history and physical form. If your child has a history of asthma, reactive airway disease, recurrent pneumonia, croup, or if your child is recovering from or has an active cold, please contact Dr. Devany three to four days before the appointment. Also, contact her early if your child has a strong history of snoring or large tonsils. If you anticipate that it will be difficult to contact you by phone, please contact Dr. Devany yourself. No anesthetic services will be provided without a phone interview first.
  4. Your child will not be able to have any food after midnight the night before the procedure. He or she can have clear liquids (water, kool-aid, gatorade, apple juice, regular jello, regular popsicles) up to three hours before the appointment time.

You cannot leave the building premises after the procedure starts while your child is anesthetized.

  6. Bring another adult so one of you can sit beside your child on the ride home.
  7. Plan to arrive at the office 20-30 minutes before the appointment. We strive to keep appointments on time, but just like with any surgery the appointment time should be considered a guideline.

Dr. Greenhill and Staff Working at Union Pediatric DentistryI.V. Sedation Pre/Post-op Instructions

What to do and what to expect on the day of your appointment:

  1. Your child may not have any food, milk, orange juice, gum or candy after midnight. He or she may have clear liquids up to 4 hours before the appointment.
  2. Plan to arrive at the office 15 minutes before the appointment. This will allow time for any paper work to be completed.
  3. For most children, the next step will be receiving the N2O (laughing gas) or “sleepy air”. Some toys are used to help distract from the start of the intravenous line (I.V.). Sedation is then started in the intravenous line. Parents can stay with their child until the sedation is started. Your child will not remember anything after this point including your leaving for the waiting room.
  4. Some small children and children with special needs will receive a quick shot in the arm which will produce a rapid drowsiness. Again, parents can stay until the sedation is started and the child will no longer remember them leaving.
  5. While your child is sedated, he/she will be monitored with the same equipment as used in a hospital setting (EKG, blood pressure, respiratory status, oxygen level). In addition, oxygen will be given. Dr. Greenhill or Dr. Jennison will administer any local anesthetic that is necessary. Your child will take a “nap” while the dental work is being done.
  6. At the end of the dental procedures, your child will wake up. He/she will still be drowsy and drunk-like. Most children wake up smoothly. However, it is normal for some children to be fussy. You will be able to hold your child during this time. Soon, you and your child will be able to go home. You will be discharged when your child can talk and stand up with help.
  7. On the way home an adult should sit beside your child. Your child should be restained in an age appropriate car seat, booster seat or seat belt. If your child falls asleep in the car make sure the chin is lifted up and not in a chin to chest position. This will keep the airway open.
  8. When you arrive home your child can sleep but not in the bedroom where they cannot be seen. He or she should be in a room like the living room where you can watch him/her.
  9. At home, start with clear liquids, like gatorade, kool-aid, 7up or apple juice. Avoid dairy and plain water for a few hours. Ginger-ale has natural anti-nausea properties. Soft food can be added next. Later, your child can progress to a regular meal as tolerated.
  10. For the remainder of the day, do not let your child do activities that require coordination like riding a bike, climbing, swimming, sledding etc.
  11. If your child vomits, refrain from offering food and drinks for one hour. Start again with clear liquids. If it happens again, call Dr. Devany.
  12. Also contact Dr. Devany if your child develops a temperature > 101˚F or if there is swelling of the mouth or airway, or if you have any other concerns.
  13. Please ask any questions that you or your child have. We want this to be a safe and pleasant experience for both you and your child.

Outpatient General Anesthesia

at Cincinnati Children’s Hospital Medical Center

Outpatient General Anesthesia is recommended for apprehensive children, very young children, and children with special needs that would not work well under nitrous oxide or I.V. sedation. Those children with extensive dental needs may be best suited for this option. General anesthesia renders your child completely asleep. This would be the same as if he/she was having their tonsils removed, ear tubes, or hernia repaired. This is performed at Cincinnati Children’s Hospital Medical Center (Main Hospital or Liberty Campus) in an outpatient setting. For patients with more complex medical needs, an overnight stay may be required. While the assumed risks are greater than that of other treatment options, if this is suggested for your child, the benefits of treatment this way have been deemed to outweigh the risks. Most pediatric medical literature places the risk of a serious reaction in the range of 1 in 25,000 to 1 in 200,000, far better than the assumed risk of even driving a car daily. The inherent risks if this is not chosen are multiple appointments, potential for physical restraint to complete treatment and possible emotional and/or physical injury to your child in order to complete their dental treatment. The risks of NO treatment include tooth pain, infection, swelling, the spread of new decay, damage to their developing adult teeth and possible life threatening hospitalization from a dental infection.
