Does anesthesia during tooth extraction during pregnancy affect the baby?

From a medical point of view, anesthesia has a very big impact on the fetus. If there is no necessary situation, the doctor will not give anesthesia to pregnant women. Because anesthetics may pose a fatal risk to the fetus, the fetus's body is relatively weak and its immunity is reduced, and anesthetics are drugs that contain certain irritants. So, does anesthesia during tooth extraction during pregnancy have any effect on the child?

Does anesthesia have any effect on the fetus?

Although obstetric anesthesia is not technically complicated, its risks are relatively high. First, during pregnancy, the physiology of pregnant women undergoes significant changes, which can directly or indirectly affect obstetric anesthesia, and in serious cases even endanger the life of pregnant women; secondly, anesthesia techniques and drugs can have different degrees of impact on pregnant women and fetuses;

Pregnant women require less anesthetic drugs than non-pregnant women, whether for epidural or general anesthesia. In spinal or epidural anesthesia, smaller amounts of local anesthetic can achieve the ideal flat surface. It is generally believed that due to the increased abdominal pressure in pregnant women, the epidural veins are dilated, thereby reducing the space between the epidural and subarachnoid spaces, resulting in a decrease in the amount of local anesthetic used. But some people believe that the reduction in the use of local anesthetics is due to the greatly increased sensitivity of pregnant women's sympathetic nerves to local anesthetics.

Clinical trials have shown that the need for inhaled anesthetics in pregnant animals during general anesthesia is reduced by up to 40% compared with non-pregnant animals. Other studies have shown that the minimum effective intramuscular concentration (MAC) of inhaled anesthetics in pregnant women is significantly reduced. Some people think that it is caused by changes in various female hormones in the pregnant woman's body during pregnancy. Some people also believe that the decrease in the MAC of anesthetics inhaled by pregnant women is due to changes in the endorphin system of pregnant women, which increases their tolerance to pain. In summary, whether it is epidural or general anesthesia, pregnant women are more sensitive to various anesthetics and the dose should be kept as low as possible.
