A Comparison of Sedation-related Events for Two Multiagent Oral Sedation Regimens in Pediatric Dental Patients

Purpose: This study compared the incidence of adverse sedation-related events occurring with two different multiagent oral sedation regimens in pediatric dental patients. Methods: Forty healthy patients (three to six years old), received either a sedation regimen of chloral hydrate, meperidine, and hydroxyzine with nitrous oxide (CH/M/H/N2O; N=19) or a regimen of midazolam, meperidine, and hydroxyzine with nitrous oxide (MZ/M/H/N2O; N=21). The two treating dentists answered a questionnaire regarding the perioperative period. Parents received two phone interviews at eight and 24 hours after sedation. Statistical analysis included chi-square, Pearson correlation coefficient, and t-test (P<.05). Results: Children sedated with MZ/M/H/N2O showed a significant increase in hyperactivity during dental treatment, slurring/difficulty speaking, and difficulty walking postoperatively within eight hours after discharge. Children sedated with CH/M/H/N2O showed a significant increase in frequency of sleeping, talking less than normal after arriving home, and an increased need for postoperative pain medication. Conclusions: Different oral sedation regimens produce different adverse sedation-related events. The provider of pediatric oral sedation should select a sedative regimen with an adverse sedation-related profile that he/she believes is optimal for the patient being treated. Parents should be counseled as to possible postsedation effects anticipated based on the sedative regimen administered.
