Avaliação da sangria como método de controle imediato da pressão arterial em pacientes submetidos a procedimentos odontológicos

Abstract

Introduction: High blood pressure, even in controlled hypertensive patients, is a risk factor that makes it impossible to perform the dental treatment that requires anesthesia. Traditional Chinese Medicine has studies and techniques for the control of blood pressure, among them is bleeding at the apex of the ear, which has as one of the functions hypotension. Objective: to evaluate the immediate control of blood pressure by means of bleeding technique and to evaluate if the pressure is maintained throughout the dental treatment. Materials and Methods: This was an experimental human clinical trial of a quantitative nature in 65 volunteers who were previously with blood pressure above 140/90mmHg. These had the pressure measured 5 minutes after the first measurement and then performed bleeding. Subsequently the pressure was measured 15 minutes after bleeding, after anesthesia and at the end of the procedure. Results: There were significantly more successes than failures. In addition, there was clearly sex influence with higher failure rates in men. In those who were successful, the pressure remained at the recommended levels after anesthesia and at the end of the procedure. Conclusion: The technique of bleeding at the apex of the ear was able to reduce the pressure satisfactorily in most cases, remaining at the recommended mean levels even when verified after anesthesia and at the end of the procedure.
