Abstract: Objective:To observe the clinical efficacy of nitrous oxide inhalation in oral and maxillofacial surgery.Methods:1 80 pa-tients underwent maxillofacial surgery were randomly divided into 2 groups(n =90).The patients in group A were given nitrous oxide inhalation before surgery,those in group B were served as the controls.The blood pressure(BP),heart rate(HR)and oxygen saturation of blood(SpO2 )were monitored during surgery,the feelings of the patients for surgical procedures,pain VAS score and Houpt behavior rating scale were surveyed after surgery.Results:In the whole operation process,BP,HR and SpO2 of group A changed smoothly(P >0.05),BP and HR of group B increased during operation(P <0.05),SpO2 had no obvious change(P >0.05);Frankl treatment adher-ence score in group A and B was 3.66 ±0.05 and 2.91 ±0.05 respectively(P <0.05);Houpt behavior rating scale were 5.06 ±0.1 1 and 3.29 ±0.06 respectively(P <0.05).VAS score in group A was lower than that in group B(P <0.05).Mild adverse reaction was observed in 6 cases in group A.Conclusion:In the process of maxillofacial surgery,nitrous oxide inhalation has sedation,analgesia and anti-anxiety effects without severe adverse effect.
