Whether or not painless abortion requires hospitalization and how many days you need to stay in the hospital depends on the patient’s specific situation. Painless abortion is an outpatient surgery. Generally, women who are in good health, with normal pregnancy and gestational sac less than 10 weeks can go home and recuperate after 1-2 hours of post-operative observation if the surgery goes well and do not need to be hospitalized. However, in case of heavy bleeding, deep anesthesia, respiratory failure, etc., it is recommended to stay in the hospital for 1-2 days for observation, and then be discharged after the blood count and respiratory indexes are stabilized. If a woman’s pregnancy sac is larger than 10 weeks, she may need to take misoprostol before the operation, or use carboprost pessary to soften the cervix, and the probability of intraoperative bleeding is higher, it is generally recommended to stay in the hospital before the painless abortion, under the guidance of the doctor to use medication, and the uterus may need to be cleared to prevent residuals during the operation, and after the uterus is cleared, it still needs to stay in the hospital for observation, and it may need to take 5-7 days, and the uterus can be discharged after the uterine contraction is good, and the bleeding stops. If the patient has a combination of more serious medical and surgical diseases, the patient needs to be hospitalized according to the type of comorbidities, the results of preoperative consultation with various doctors and postoperative conditions, and the number of days of hospitalization is not certain. Before painless abortion, patients must complete all the examinations, and when there are comorbidities, they should inform the doctor in time to avoid increasing the risk of postoperative accidents.
