. . . A few days ago, a report entitled “Men who bleed for more than 10 days after pulling out their wisdom teeth” was reprinted by many websites and attracted wide attention. Many people who have pulled out their wisdom teeth said that they were shaking and thanking themselves that they were fine. Many people who had never pulled their wisdom teeth shivered, saying they did not dare.  . . . . Let us briefly review this incident. The patient Liu, male, 26 years old, had his wisdom teeth removed at the Zhongnuo Stomatological Hospital in Changsha on May 25, and he subsequently bleeds. He communicated with the doctor on WeChat during the period and did not go to the hospital for further treatment until June 4 The patient was diagnosed with a suspected acute leukemia, cellulitis of the maxillofacial region, sepsis, and lung infection. The patient was subsequently rescued due to concurrent cerebral hemorrhage and cerebral hernia. .  . . . . In fact, deaths due to tooth extraction are extremely rare, and tooth extraction will not be a direct cause of death. Serious complications during tooth extraction are often caused by systemic diseases in other aspects of the body, such as heart disease, blood diseases, and malignant tumors. So we still have to calm down our minds. When it comes time to extract teeth, we have to resolutely pull out, and we should not waste food because of choking. Next, I want to talk about what should we do if the bleeding continues after tooth extraction.  . . . . The best treatment is prevention. Doctors will fully understand the patient’s physical condition before the operation, assess the possible risks, and try to avoid dangers. For example, for the complication of bleeding after tooth extraction, we usually have to carry out the following preparations: 1) ask whether the patient has systemic diseases such as high blood pressure, hemophilia, leukemia, etc. 2) ask whether the patient takes aspirin, polyvi, etc. Anticoagulant drugs 3) Preoperative blood test routine and coagulation routine, check whether the patient’s coagulation function is normal 4) Take X-ray film or CT, check the relationship between tooth root and peripheral neurovascular 5) Check whether the soft tissue around the tooth has inflammation, whether it is easy Bleeding . . . . . . . These are all risk factors that may cause bleeding after tooth extraction, we must carefully investigate. Therefore, when you go to pull wisdom teeth, the doctor repeatedly asks you if you have various diseases, whether you take any medicine, and then let you take a blood test for various tests. Don’t think that the doctor is deliberately making you difficult. We do all of these. In order to ensure the safety of the operation, I hope everyone understands and cooperates with the doctor.  . . . . Many years ago, our department had a young patient. The patient actually had hemophilia, but he did not know it. At that time, we did not have all patients routinely check blood before surgery. Therefore, no problems were found in advance in patients’ coagulation. After the wisdom tooth extraction, the patient had more bleeding in the extraction socket. We filled the extraction socket with iodoform gauze and sewed it tightly. The bleeding stopped temporarily. One week later, he had bleeding in the extraction socket when he removed the thread, so he was tested for coagulation function, and the patient was found to have hemophilia. The lack of coagulation factors caused abnormal coagulation. After finding the cause, supplement it with the corresponding coagulation factor, and the problem of bleeding is solved.  . . . . In addition, patients with high blood pressure, leukemia or taking anticoagulant drugs may cause postoperative bleeding. You must tell the doctor truthfully when you visit the doctor.  . . . . Under normal circumstances, the bleeding in the extraction socket will coagulate within half an hour, the blood clot will completely clot in about 2 hours, and the blood clot will begin to organically form granulation tissue in 24 hours. Therefore, after tooth extraction, we will tell the patient to bite the gauze for 40 minutes, and then eat two hours after the operation. It is advisable to eat cold soft food. Do not brush your teeth and rinse your mouth within 24 hours after the operation to avoid licking the wound. These measures are for Protect blood clots in extraction sockets to prevent postoperative bleeding.  . . . . Of course, there is no problem with all of the above, and some patients will have bleeding after tooth extraction.
