Summary

The surgery for the extraction of the third molars is a procedure in Dentistry that generates a large picture of anxiety in the patient. One of the ways to try to soften this picture, are the professionals to use sedation. Thus, the objective of this study was to evaluate three sedation protocols, and to compare them with vital signs values, in order to obtain the sedation method with greater patients stability.

Detailed description

The surgery for the extraction of third molars is one of the procedures in Dentistry that generates a great picture of anxiety in the patients, due to the expectation of pain and discomfort in the postoperative period, but mainly in the trans-operative period. One of the ways to try to minimize this situation is to use sedation, which is a relatively safe procedure performed by trained professionals and with an accurate indication for anxious patients. There are several protocols in the literature, but few comparative studies. Thus, the objective of this study was to evaluate three sedation protocols. For this purpose, 120 patients who required surgical treatment for extraction of third molars, aged between 18 and 30 years, and whose anxiety was moderate to severe according to the Corah Anxiety Scale from the School of Dentistry of São José Dos Campos (UNESP). These patients were randomly divided into three Groups: Group I - oral sedation with diazempam 5 mg; Group II - oral sedation with midazolam 7.5 mg and Group III - inhalation sedation with 40% of nitrous oxide . Prior to sedation, anxiety was quantified through the Corah Anxiety Scale. Vital signs (blood pressure, heart rate and oxygen saturation) were measured before sedation, after sedation, in the trans-operative period and 15 minutes after the end of sedation. The results will be submitted to descriptive statistics and compared using the statistical analysis of variance (ANOVA) and Tukey test with significance level of 5%.

Interventions

Type	Name	Description
DRUG	Diazepam	Patients' vital signs (blood pressure, heart rate and oxygen saturation) were measured and recorded after 30 minutes of oral sedation with diazepam 5mg, during the extraction procedure and 15 minutes after the extraction. After the surgical procedure of extraction, the patients remained in recovery in the same room, being the criteria of discharge realized, from the normality of the vital signs and the response to the verbal commands, with the patient responsive and lucid.
DRUG	Midazolam	Patients' vital signs (blood pressure, heart rate, and oxygen saturation) were measured and recorded after 30 minutes of oral sedation with midazolam 7.5mg during the extraction procedure and 15 minutes after the extraction. After the surgical procedure of extraction, the patients remained in recovery in the same room, being the criteria of discharge realized, from the normality of the vital signs and the response to the verbal commands, with the patient responsive and lucid.
DRUG	Nitrous Oxide + Oxygen Gas	Patients' vital signs (blood pressure, heart rate, and oxygen saturation) were measured and recorded after 30 minutes of sedation Inhalation with the mixture of 40% of nitrou oxide and 60% of oxygen, during the exodontia procedure and 15 minutes later. After the surgical procedure of extraction, the patients remained in recovery in the same room, being the discharge criteria performed, from the normality of the vital signs and the response to the verbal commands, with the patient responsive and lucid, and after the accomplishment of the test developed by Trieger et al.,(1971).
