RESUMO

The purpose of this controlled and double-blind trial was to evaluate cardiovascular effects induced by pterigomandibular block of local anesthetic (LA) 2 % lidocaína hydrochloride with epinephrine, followed administration of benzodiazepine (midazolam 15mg on hour prior) or placebo during the surgical phase of placement of the lower bilateral dental implant in 22 normotensive outpatients (13 female and 9 male). The cardiovascular parameters systolic (SP), diastolic (DP) and mean (MP) pressures and heart rate (HR) were monitored by oscillometric and photopletismographic methods in 06 clinical phases during the procedure. The mean values were recorded every minute and in a continuous way during the phases of the experiment following the sequence: phase 0 basal period; phase 1 - anesthesia local; phase 2 mucoperiostal flap; phase 3 perforation; phase 4 placement of dental implants; phase 5 suture; phase 6 the end period. The group with received midazolam didnt induce significant SP, DP, MP and HR changes (p>0.01) compared to placebo. Significantly higher values in placebo group and mean values in midazolam group in heart-frequency were observed.
