Anesthetic poisoning

Local anesthetics include procaine, cocaine, lidocaine, marcaine, carbocaine, pricacaine, etc. The nervous system plays a suppressive role, but when it is poisoned, it can cause central nervous excitement, cardiac depression, vasodilation, etc., and related symptoms appear. In recent years, during the delivery of pregnant women, some of the above-mentioned local anesthetics are often used for analgesia. Such drugs can be passed through the placenta after being absorbed by the mother, causing neonatal poisoning; occasionally due to sacral block or peripheral anesthesia, accident Injecting local anesthetics into the fetus can cause severe poisoning symptoms in newborns. Newborn infants' liver and kidney development are not yet mature, and their metabolism and excretion functions are poor.
