Abstract:
Objective:To study the effects of nitrous oxide(N2 O)sedation in the management of dental fear(DF)for dental treat-ments of children.Methods:66 cases of pediatric patients(aged 6 to 14 years)were given N2 O sedation for dental treatments.The heart rate(HR)and oxygen saturation(SpO2 )were measured before and after N2 O inhalation.N2 O effective concentration was eval-uated by Ramsay sedation score and Houpt behavior score.Results:The effective concentration of N2 O sedation was 25% -70%(49.6% ±12.1%),the maximum endurance concentration 35%-70% (56.4% ±10.1%).The Ramsy scores of N2 O sedation was (2.3 ±0.6).After N2 O inhalation,all patients could receive verbal demand during the treatments.The HR decreased(P <0. 05)and the Houpt behavior score increased(P <0.01).Before and after N2 O inhalation SpO2 had no significant difference(P >0.05).Conclusion:N2 O inhalation at 25% -70% is safe and effective in the management of DF for dental treatments of children.
