70 Cases of Patients with No Stopping Aspirin Research Xinsheng HUANG1,a , Daofeng LIU1,band Yanbin HUANG1,c 1 Shengli oilfield central hospital No. 31, Jinan Road #1, Dongying City, Shandong Prov. 257034, China Keyword: aspirin, tooth extraction, bleed. Abstract: At present, there are many people with long-term use of aspirin. Before the tooth extraction, patients should stop using aspirin, but this will increase system disease risk. Our research team use local treatment without stopping aspirin, and achieve good hemostatic effect. 1. Instruction At present, the number of patients who have hypertension, cerebral thrombosis, coronary heart disease and valvular dysfunction increase year by year, and the patients should take aspirin for a long time. If the patients have got teeth defect or periodontal disease, they should stop taking aspirin to recover their function of anticoagulation, but this may increase the risk of system disease. Since 2005, our research group use local treatment without stopping aspirin, and achieve good hemostatic effect. 2. Data and method 2.1 clinical data From 2005 to 2011, there were 70 patients who took tooth extraction with taking aspirin in Central hospital in Shengli Oil Field. And there were 38 cases of male and 32 cases of female. And the age of the patients was 50 to 72, and the average age was 61.5. There were 20 cases of coronary heart disease, 17 cases of intervention stents and 33 cases of prevention. All of the patients should take blood routine, electrocardiogram, blood pressure, blood clotting, blood sugar to exclude acute myocardial infarction (AMI). And the standard data was shown below. Table 1 standard data Test blood pressure (mmHg) Cruor (s) APTT (s) FBG (g/L) INR Data 100-175/60-100 10.0-14.0 23.0-38.0 2.0-4.0 0.8-1.2% PA TT (s) Blood sugar (mmol/L) >70% 14.0-18.0 8 The myocardial infarction should never happen, and there was not hematostaxis in the mouth and digestive tract, and there was not purpura or ecchymosis. And the patients should be exluded oral infection and ulcers. And 90 teeth were pulled out total. 2.2 method and step All the patients should not stop taking aspirin. The mouth should be disinfected by iodine. The mouth should be narcotized by 2% lidocaine. Plier pull technique should be adopted, and gum should be completely isolated before the tooth extraction. And granulation should be cleared away after the tooth extraction. The patients should bite styptic cotton, and processed suture by the condition of the wound. And the patients should be taken local cold. And the patients could leave after observing 60min without bleeding. And the patients should take pill to prevent infection. 3. Results All the patients were reviewed after two days, and it was happened that 5 cases were found visible ecchymosis and hematoma which were taken the local anaesthetic injection, and none of them were found bleeding. And none of the patients were found serious infection. 4. Discussions The tooth indication and contraindication is not absolutely correct, and it is based on the specific condition. Atherosclerosis and the disease of heart head blood-vessel rise year by year, and the anticoagulation drug (such as aspirin) was taken on a long time, and it may lead to the tooth bleeding if the doctor do not notice the patients the instructions. Such bleeding is often for a long time, and it has no special treatment, so it lead to the fear of the patients and more aggravate bleeding tendency. Aspirin is also called b phthalic acid, and it belongs to non-steroidal anti-inflammatory, and its functions is antipyretic, analgesic, anti-inflammatory and anticoagulation. It is widely used in the remedy of the cold, fever, headache, rheumatism, cardiovascular and so on. Low concentration aspirin can inactivate b phthalein of PG synthetase(COX), and it can result in the irreversible inhibition of platelet cyclase, and it promotes the decreased production of the thromboxane A2(TXA2), and it influences the formation of the thrombus[1]. Long term use of aspirin can lead to the dysfunction of platelet, reduction of blood coagulation and bleeding after tooth extraction. To solve the above problems, our research group first emphasize the check before the tooth extraction, and make the patients in a healthy state. The doctors should separate the gum before the tooth extraction, because the gum torn is the main cause of bleeding after the tooth extraction, and it is difficult to stop bleed with the method of oppression. And the process of the operation must be soft and fast to reduce the local trauma. The granulation tissue must be removed from the phatnoma. If the granulation tissue is not removed thoroughly, it will be difficult to clean up again, and the nest bone quality of phatnoma which has the granulation tissue will reduce. Oppression hemostasis, local cooling, filled with gelatin sponge and suture are adopted after the tooth extraction. The method that the wound is covered with hemostatic lap and bite oppression can reduce the local blood circulation to stop bleeding. Local cooling can result capillary contraction around the tooth area, lower blood flow and lower permeability to stop bleeding. The gelatin sponge is soft, breathable, stronger adsorption ability and better histocompatibility, and it can be absorbed slowly by the body. The gelatin sponge is stuffed into the alveolar and it can absorb many times weight more than its weight, and the blood flow into the sponge to absorb the blood platelet to have action with coagulation factor to coagulate the blood platelet. And it can prompt the blood platelet burst at the same time, and it releases coagulation material to prompt the fibrinogen to fibrin to coagulate blood. The dissolution and the degradation on the wound of gelatin sponge can change the local viscosity to prompt the coagulation[2]. The suture can reduce the area of the wound to stop bleeding. Through the above measure, it can accelerate the coagulation of the blood to constraint the local bleeding. The method that the local treatment which is without stopping taking aspirin can constraint the local bleeding. And this method can solve the oral disease without hinder the treatment of the system disease. Reference [1] Loll PJ, Picot D, Garavito RM, et al.
