Conscious Sedation Using Nitrous Oxide and Midazolam for Dental Procedures in Pediatric Patients in Armed Forces Hospital – Our Experience

Abstract

Abstract Background and Aim: Management of pain and anxiety associated with dental procedures in pediatric age group is a big challenge. In this part of the world, counselling has been the main modality for managing such patients. It is associated with mixed outcome. We share our experience of managing 23 patients using a combination of inhalational nitrous oxide- oxygen and intravenous midazolam with satisfactory outcomes. Material and Methods: Patients aged more than six years, American society of anaesthesiologists classification (ASA) I or II, procedure that could be finished within one hour like pulpectomies, root canal treatments, extraction and multiple restorations were accepted for conscious sedation. Complete blood count was done and pre-anaesthetic checkup (PAC) with written informed consent from the parent was taken for the dental procedure under conscious sedation. We placed the nasal mask of the Conscious sedation anesthesia machine and made the child inhale Oxygen/Nitrous oxide mixture. After inhaling variable concentration of nitrous oxide/ oxygen mixture in proportion increasing from 30:70 to 70:30, procedure was done. After completion of the procedure, the patient was administered hundred percent oxygen for five minutes. Results: We have done a total of twenty-three cases till now with ages between five to seventeen years. The duration of procedures ranged from 30 min to one and half hour. Two patients less than six years were found to be uncooperative for the procedure. Conclusion: Minimum age group that was suitable for conscious sedation was six years and above. Frequent meetings and counselling by the same team should be facilitated prior to taking up for the procedure.
