Variação da pressão arterial durante procedimentos odontológicos com o uso de anestésicos locais.

Abstract

The object of this article is to analyze the variation of blood pressure during dental procedures. The method used was the development of a study from an evaluation of 66 patients on dental treatment on the Dentistry Clinic of Universidade of Santa Cruz do Sul. They were divided in two groups: Group A (n=33) patients that have been in surgery, Group B (n=33) patients submitted to. Three measurements of the blood preassure were made: before the procedure (moment 1); 10 minutes after the o application of local anesthesia (moment 2); 5 minutes after ending the procedure (moment 3). For the procedures, it was used the local anesthesia Alphacaine® (Lidocaine 2% with Epinephrine 1:100.000) – new DFL. During the research, two Digital Monitors the blood pressure(OMRON® - Model HEM-7113) previously calibrated were used. The results showed that the blood pressure systolic changed statistically significant between the moments 2 and 3 (p = 0,007), being the moment 3 greater. On patients submitted to restoration treatments, it was observed difference statistically significant between moments 2 and 3 (p = 0,0044), being the moment 3 greater. Between surgical treatments and restoration treatments, there was a difference statistically significant on moment 2 of each group (p = 0,02280), being moment 2 of group A greater. The diastolic blood pressure showed difference statistically significant between moments 1 and 3 (p = 0,0268) and between moments 2 and 3 (p = 0,0003), being moment 2 greater in both. On patients of restoration treatments, there was a difference statistically significant between moments 1 and 3 (p = 0,0066) and 2 and 3 (p = 0,0001), being moment 2 greater in both. It is concluded that fear, stress, anxiety and pain are possibly the major cause of increased blood presssure and that the use of local anesthetics with vasoconstrictor at the recommended doses does not significantly alter blood pressure.
