Abortion surgery is divided into ordinary abortion and painless abortion, ordinary abortion can not drink water before 2 hours before abortion, painless abortion needs to be fasted for 4 hours before abortion, so it is not advisable to drink water: 1. Ordinary abortion: if you are doing ordinary abortion, you do not need to play anesthesia, and you can not drink water within 2 hours before the abortion surgery, so that you can reduce the risk of accidental suction during the surgery; 2. Painless abortion: if you are doing painless Painless abortion: If you are having a painless abortion, you can’t drink water within 4-6 hours before the abortion, and you have to fast within 6-8 hours. The reason why to do painless abortion within 6 before fasting and water, because painless abortion needs to be carried out under the effect of anesthesia drugs. After the injection of anesthetic drugs, the patient enters into a state of anesthesia, physiological reflexes disappear, and pain disappears. If you eat or drink before the operation, the food in the stomach can not be excreted in time, there may be nausea and vomiting in the process of anesthesia, the patient can not be discharged through the mouth in time, it is likely to accidentally enter the trachea resulting in asphyxiation, resulting in life-threatening injuries. Before the abortion surgery, you can make preoperative preparations under the doctor’s guidance, and actively cooperate with the doctor during the operation to avoid excessive tension and anxiety. About 10 days after the abortion surgery, you need to go to the hospital for a follow-up ultrasound to determine whether the uterine cavity has returned to its normal shape, so as to avoid the presence of residual tissue in the uterine cavity, which may cause infection and bleeding.
