Painless removal of the uterus under anesthesia usually takes about 5 minutes to regain consciousness. IUD removal involves the use of negative pressure suction to clean the placenta and fetal tissue. The difference between painless and normal removal is the anesthetic used. Painless removal uses an anesthetic with a greater range of anesthesia, such as isoproterenol, and no pain is felt during the removal. A regular clearance is just a local anesthetic, such as lidocaine, and the clearance process can be painful. The procedure can be completed in 3-5 minutes, isoproterenol is metabolized quickly in the body, usually about 5 minutes after the end of the procedure to regain consciousness, but the operation needs to be observed, if there is no heavy bleeding, dizziness and other conditions before leaving. After clearing the uterus, women should eat more food rich in protein, such as eggs, pork lean meat, soy products, milk and so on. It is also necessary to properly supplement shrimp, fish, pork liver, oats, walnuts, peanuts and other foods, eat more fresh vegetables and fruits, to ensure that the intake of food nutritionally balanced, to avoid a single nutrition. If bleeding occurs after purging, which is not relieved by proper rest and shows a trend of persistent aggravation and is accompanied by the manifestation of abdominal pain, you should consult a doctor as early as possible, and after a clear diagnosis of the causative factors, you should treat and regulate the symptoms under the guidance of the doctor.
