Most women with epilepsy will have an increase in seizures after pregnancy and have a significantly higher rate of obstructed labor than those without epilepsy. Therefore, it is necessary to: 1. control seizures before pregnancy: some people have statistics that 50% of those who have controlled seizures before pregnancy can remain seizure-free, 5% have fewer seizures, and 45% have more seizures. If they have more than 1 seizure per month before pregnancy, 60%-98% of their seizures increase during pregnancy, and often the seizures worsen during the first 3 months. The reasons for the changes in epilepsy during pregnancy are not yet understood and may be related to pregnancy toxemia, vascular damage, venous embolism, pregnancy-induced encephalopathy and decreased blood levels of antiepileptic drugs. 2, the need to continue to take antiepileptic drugs during pregnancy: some scholars believe that the increase in seizures during pregnancy is related to the decrease in the blood concentration of antiepileptic drugs, and advocate the increase of antiepileptic drugs in moderation during pregnancy. 3, the choice of medication: epilepsy pregnancy is best to single-use drugs to reduce toxic side effects, should not use phenobarbital and phenytoin sodium drugs. The reason is that the use of phenobarbital and sodium phenytoin can make the fetus teratogenic, so use effective Chinese medicine with less toxic side effects, and frequently measure the blood concentration of antiepileptic drugs to determine the lowest effective dose. 4. Prevent complications of epileptic pregnancy: It has been reported that the incidence of complications during pregnancy in epileptic patients can increase by 50%, such as vaginal bleeding during pregnancy, toxemia of pregnancy, preterm delivery, caesarean section, spontaneous abortion and amnionitis, and also high infant mortality. Therefore, close cooperation between neurologists and obstetricians and gynecologists should be advocated, and patients should choose a better hospital for delivery.
