Avaliação de parâmetros cardiovasculares fisiológicos utilizando-se Betametasona e/ou Diazepam como medicação pré-operatória em cirurgia de terceiros molares inclusos

Abstract

Impacted third molar surgery is the most performed procedure by the oral

facial surgeons and it has been a model for experimentation of various drug therapy

protocols. The use of corticosteroids during oral surgeries have been evaluated the

anti-inflammatory action. However, there are no published studies that evaluate the

physiological features of the use of these drugs in Dentistry. The aim of this study is

to evaluate, during the surgery, the cardiovascular parameters influence when

betamethasone are used as preoperative therapy for the impacted tooth extraction,

analyzing patients who used diazepam or not to control anxiety. A randomized

double-blind study was made including 27 patients with no systemic alteration, who

were divided into 4 groups, which received single dose of oral preoperative drugs

and underwent surgery under local anesthesia. It was observed that betamethasone

oral administration before ambulatorial surgery procedures is a safe and effective

method to control anxiety, and keeps the cardiovascular parameters within the

values. A single dose oral administrated of Betamethasone increases cardiac

frequency and diastolic blood pressure during surgery and postoperative period, and

the association betamethasone and diazepam significantly reduces these parameters

compared to the betamethasone isolated group.
