Frequency of intraoral hematoma formation with mandibular anesthetic techniques in patients treated with oral anticoagulants

Abstract

IntroductionOne of the main problems for the dentist is the possible complications after performing a trunk anesthetic technique. These complications can develop both in healthy patients and in patients with a systemic disease. Pathophysiological, patients undergoing treatment with oral anticoagulants (TACO), have a higher risk of bruising.According to the literature, the frequency of intraoral hematomas in mandibular anesthetic techniques in healthy patients is 10-15%, being a controversial issue for patients under treatment with oral anticoagulants, because there is not enough quality evidence on anesthetic techniques trunks in this type of patient.Objectives Determine the frequency of intraoral hematomas after performing mandibular trunk anesthetic techniques in patients treated with oral anticoagulants.Materials and methods: A pre-experimental, prospective, longitudinal study of 17 patients treated with oral anticoagulants, whose INR on the day of dental care was less than 3, who underwent mandibular trunk anesthetic techniques, was carried out. The immediate visual inspection confirmed the presence or absence of intraoral hematoma formation at the puncture site after performing the anesthetic technique, which was the indirect Spix technique of choice, respecting the indicated anatomical repairs.Results Of the 17 patients, 13 presented INR less than 3, who received mandibular trunk anesthetic technique, none presented intraoral hematoma formation at the puncture site (0%).Conclusion By respecting the anatomical parameters and presenting an INR between 2-3 in TACO patients, it is suggestive that trunk anesthetic techniques are not a procedure that particularly generates a higher frequency of hematomas in the population studied compared to the healthy population, without However, it is necessary to carry out studies whose population is greater than that of the present study. Keywords: Hematoma, oral anticoagulant, mandibular troncal anesthetic techniques, oral surgery, coagulation.
