摘要
目的：研究氧化亚氮（N2 O）镇静在儿童牙科畏惧症（DF）患者治疗中应用的效果并探讨 N2 O 镇静的应用浓度。方法：对66例患儿应用 N2 O 进行镇静，观察不同浓度 N2 O 应用前后的心率（HR）和氧饱和度（SpO2）变化，分别采用 RamSay镇静评分和 Houpt 行为量表评分对镇静治疗浓度进行评价。结果：患儿镇静显效所需 N2 O 最低浓度为25％～70％（49．6％±12．1％）；最大耐受浓度为35％～70％（56．4％±10．1％）。N2 O 产生的 Ramsay 镇静评分最大值为（2．3±0．6），患儿在治疗过程中均对医生的口头指令有所响应。患儿吸入 N2 O/O2混合气体后前后 HR（次/min）分别为（89．0±15．8）和（83．4±12．1）（P ＜0．05），Houpt 行为量表评分分别为（1．2±0．6）和（4．4±1．1）（P ＜0．01），能更好地配合治疗，SpO2分别为（98．4±0．9）％和（99．1±0．9）％（P ＞0．05）。结论：25％～70％的 N2 O 用于儿童牙科畏惧是安全有效的。
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.
