Active clinical trials for "Oral Hemorrhage"

The aim of this study is to collect performance and safety data relating to the use and the follow-up of the HEMOCOLLAGENE® medical device in routine clinical practice from various hospitals and medical centers in oral dental surgery. Patients will The data collected from the Post-Market Clinical Follow-up study will be used to support the regulatory requirements of post-market monitoring (risk management, residual risks, instructions for use...) and to increase the manufacturer's clinical data. Patients will be followed for 1 month. Adverse events (safety) and device performance will be collected by the dentist during the routine follow-up visits.

Patients using anticoagulants present an increased risk of bleeding when subjected to oral surgery. Suspending or reducing the oral anticoagulant dose to perform invasive procedures, may result in thromboembolic events, putting patients health in risk. Recent studies advocate the dental surgery treatment without suspending the anticoagulant therapy, since the values of the international normalized ratio (INR) are in acceptable therapeutic levels and local measurements are taken for the hemostasis control. The aim of this study is to compare the effectiveness use of intra-alveolar epsilon amino caproic acid (EACA) associated to daily rinses with the drug, with routine post-surgical procedures, to control the post-exodontic bleeding in anticoagulated patients. Patients will be referred by the anticoagulation clinic of the Clementino Fraga Filho University Hospital. Once the study criteria is met patients will be randomly allocated into two groups and subsequently subjected to clinical and periodontal examination, radiographic examination and pre-operative periodontal therapy. Laboratory tests (partial thromboplastic time, prothrombin time, international normalized ratio and platelet count) will be held on the day of the extraction. Patients in group 1 ( EACA ) will receive a paste composed of 01 macerated EACA tablet (500 mg), mixed with 0.9% saline solution in the alveolar socket, and routine post-operative care. Additionally, patients will perform oral rinses three times a day, on the first two post-operative days, with a solution from the macerated EACA 500mg tablet diluted in 2 spoons of filtered water. Patients allocated in group 2 (control) will receive routine post-operative care. Classification of immediate bleeding will be held by the professional, on the day of the surgery, immediately after the suture and twenty minutes later and the delayed bleeding, recorded by the patient through a daily questionnaire. The Statistical Package for the Social Sciences (SPSS)© (IBM, Chicago, USA) 20.0 is used as the database and the Chi-square, Kruskal-Wallis and Mann-Whitney tests will be applied to statistical analysis of the results.The study was approved by the ethical and research committee of the Clementino Fraga Filho University Hospital . All patients will sign a free consent and informed term.
