The effect of anesthetics on pregnancy depends on the number of weeks of pregnancy. The first 3 months of pregnancy is a sensitive period for the fetus, and if anesthetics are used it will have some effect on the fetus. In the case of elective surgery, try not to choose a procedure where the fetus is within 3 months. In non-pregnant women of maternal age, anesthetics can be metabolized without major effects on their future pregnancies. In large samples of surveys, it has not been conclusively stated that anesthetic drugs have an effect on unpregnant women. Therefore, whether anesthetic drugs have any effect on pregnant women must be based on the condition of the surgery. In special cases, such as emergency situations, the pros and cons should be weighed, and the anesthesiologist will use the anesthetic drug that has the least effect on the pregnant woman, and the patient should not be overly nervous.
