药物是治疗疾病的一种重要武器。但是,如果使用不合理,可以造成不良反应。对于孕妇来说,合理使用药物显得格外重要,因为用药不当不仅对孕妇和胎儿可造成一般的不良反应,有时还会引起胎儿畸形。这已在临床观察和动物实验中得到证实。大多数药物进入母体后都能通过胎盘进入胚胎,但其中只有一部分药物影响胚胎的发育,引起胎儿畸形。药物致胎儿畸形的作用主要取决于药物的性质,此外跟胚胎的发育阶段,母体的健康状况以及药量都有关系。妊娠三个月
Drugs are an important weapon in the treatment of disease. However, if used unreasonably, can cause adverse reactions. For pregnant women, the rational use of drugs is particularly important, because improper medication not only for pregnant women and fetuses can cause general adverse reactions, and sometimes can cause fetal deformity. This has been confirmed in clinical observations and animal experiments. Most drugs enter the mother through the placenta into the embryo, but only part of the drug affects the development of the embryo, causing fetal malformations. The role of drug-induced fetal deformity mainly depends on the nature of the drug, in addition with the developmental stages of embryos, maternal health status and the amount of drugs are related.
