Do you know whether you can have a child under anesthesia without knowing whether you are pregnant or not, you need to analyze the specific situation. Injecting anesthesia during pregnancy may affect fetal development, but there are individual differences in the size of the effect, mainly related to the dose of the drug and the anesthesia method. If local anesthesia or intravenous anesthesia is used, generally speaking, the dose of medicine is relatively small, and the effect on the fetus is also small, so the fetus can be retained, but it is necessary to do a close pregnancy check. However, if the spinal anesthesia or general anesthesia, the dose of drugs is relatively large, the metabolism is relatively slow, the impact on the fetus will be greater, need to carefully choose to retain the fetus. In the case of anesthesia without knowing that you are pregnant, you should promptly explain the situation with your obstetrician and gynecologist, who will analyze the specific circumstances to determine whether or not to retain the fetus.
