The difference between a painless abortion and a painful abortion lies in the comfort of the procedure, post-operative complications, and the cost of the procedure. Painless abortion is usually carried out under general anesthesia, the patient is almost painless, surgical comfort is better, the process is smoother, largely reducing the occurrence of complications. Painful abortion without anesthesia, the patient’s pain is relatively large, may struggle, resistance, etc. to interfere with the surgical process, more surgical complications, in addition to injurious stimulation caused by pain, psychological fear, may also cause abortion syndrome, mainly manifested as a slowed heart rate, decreased blood pressure, nausea, vomiting, sweating, pale and so on. But painless abortion increases the anesthesia operation, the anesthesia drug will inhibit the respiration as well as part of the nerve function to varying degrees, which will increase the risk of surgery. Resuscitation is required after anesthesia, which extends the operation time to some extent and is more expensive. Painful abortion does not have the risk of anesthesia, you can leave the operating bed after the operation and proceed to the next treatment, and the cost is cheaper. There is no significant difference in the probability of postoperative infection between painful abortion and painless abortion, patients need to prevent infection, generally need to return to the hospital 2 weeks after the operation for review, and need to rest in bed after the operation.
