Introduction: Although more than a month has passed, Chen from Guangshui is still overwhelmed with guilt every day: if only she had been firmer in persuading her husband not to get his tooth extracted, he might still be alive today.
Chen and her husband Liu reside in Changling Town, Guangshui. Seven years ago, they came to Shiyan to work. On the 12th of last month, Liu suffered from a toothache and didn't sleep well all night. The next morning, he went to a nearby hospital for an injection. Before leaving, Chen reminded him to just get the injection and not to have the tooth pulled.
At around 11 a.m., when Chen returned home after work, she saw that her husband was also back, but there were still traces of blood on his teeth, and he was groaning in pain. Chen hurriedly asked what happened, and Liu, enduring the pain, said that two teeth had been extracted. A little while later, Liu told his wife that the toothache was unbearable, he couldn't speak, and he didn't want to eat. He decided to go to sleep.
At 1:30 p.m., considering that her husband hadn't slept well the previous night, Chen did not wake him up and quietly closed the door to go to work. At 5:30 p.m., a coworker surnamed Luo called out to Liu outside his room to wake him up, but after calling several times with no response, he went inside to check and unexpectedly found Liu's face looking abnormal, and upon touching his cheeks, there was no temperature. Luo felt something was wrong and quickly dialed the emergency number. Despite the medical staff arriving promptly, they were unable to save Liu from death.
After identification by the Forensic Medical Laboratory of Yunyang Medical College, combined with the circumstances of death, it was comprehensively analyzed that Liu died suddenly due to acute central nervous system failure caused by a malformed right communicating branch of the basilar artery ring, rupture of arteriovenous malformation, subarachnoid hemorrhage, and formation of cerebellar tonsillar herniation.
Experts remind us that although tooth extraction is a minor surgery in oral clinics, adequate preparation must be done beforehand. Patients with systemic diseases can only undergo tooth extraction when their conditions are under safe control, and necessary examinations and treatments should be carried out before the procedure. If handled improperly, it may cause harm to the body or even endanger life.
Precautions before tooth extraction:
1. Do not fast before tooth extraction; it should be performed between 8:00 a.m. and 3:00 p.m. Rest well the day before, and pay attention to mental relaxation... Actively inform the doctor about your personal health status.
2. Be aware of the following diseases where tooth extraction is contraindicated:
(1) Heart disease: ① Heart disease occurred within the last 6 months. ② Unstable or recent angina. ③ Congestive heart failure. ④ Uncontrolled arrhythmia. ⑤ Obvious uncontrolled hypertension.
(2) Congenital heart disease, rheumatic heart disease, and patients who underwent surgery for such diseases. To prevent subacute bacterial endocarditis, antibiotics should be administered before and after the surgery.
(3) Hypertension: Those with blood pressure higher than 180/100 mmHg should receive treatment.
(4) Diabetes: Uncontrolled diabetes increases the risk of infection after tooth extraction and affects wound healing. Blood sugar should be below 9 mmol/L without acidosis symptoms before proceeding with the extraction, and antibiotics should be given before and after the surgery to prevent infection.
(5) Hyperthyroidism: Tooth extraction can lead to a thyroid crisis. If tooth extraction is necessary, basic metabolism should be controlled at +20 or less, pulse rate should not exceed 100 beats per minute, and anti-infection measures should be taken before and after the surgery. Adrenaline should not be used during local anesthesia.
(6) Other internal diseases, such as nephritis, hepatitis, and blood disorders. Various preventive measures should be taken before and after the surgery.
(7) Tooth extraction during pregnancy should be performed during the 4th, 5th, and 6th months of pregnancy for safety.
(8) Teeth in the acute inflammatory phase can be extracted after the inflammation is effectively controlled, and oral antibiotics should be taken after the surgery to prevent infection.
