Injections for pregnant women means performing injections, including vaccinations, intramuscular injections, intravenous injections and other medical acts. Since injection treatment is fast, but the risk is higher compared to oral medicine of the same efficacy, so generally for pregnant women, oral medicine is needed instead of injection, but the choice of specific types of treatment, such as whether to inject, still depends on the pregnant women’s own health, treatment needs, drug type, drug safety and other factors, decided by the doctor’s comprehensive judgment. I. Cases that can be injected 1. Partially inactivated vaccination: pregnant women at all stages can be injected with inactivated influenza vaccine, acellular pertussis vaccine, diphtheria vaccine, tetanus vaccine, hepatitis B vaccine, rabies vaccine, etc.; 2. Control of acute symptoms during pregnancy: women with long-term diseases, such as immune system diseases, need to use injections to control the development of symptoms, such as women suffering from acute rheumatoid arthritis, in For example, women with acute rheumatoid arthritis may experience acute arthritis attacks or aggravation during pregnancy, and for joints with obvious swelling, glucocorticoids can be injected into the joint cavity; 3, long-term injections to maintain symptoms: if women have chronic diseases before or during pregnancy, sometimes it is necessary to control symptoms and stabilize indicators by injecting drugs, such as women with diabetes during pregnancy, under the guidance of a doctor, it is necessary to inject insulin to control blood sugar if necessary For example, women with diabetes during pregnancy may need insulin injections to control blood sugar under the guidance of a doctor, if necessary, to prevent its aggravation from causing various complications and even affecting the fetus. Second, the cases that can not be injected 1, prohibited vaccines, vaccines that have not been clinically validated: such as live attenuated vaccines, live vaccines, partially inactivated vaccines: such as measles vaccine, rubella vaccine, BCG vaccine, etc. are not recommended to be injected during pregnancy, in addition, HPV vaccine, new crown vaccine, etc. there is no clear evidence to prove whether it is harmful to the fetus, but also usually can not be injected; 2, the presence of alternative topical or oral drugs: pregnant women The need for injection needs to be assessed, and injections should only be given under adequate medical indications to avoid unnecessary harm to the pregnant woman and fetus caused by drug abuse. If a woman has an infection that can be treated by taking antibiotics, there is no need to choose intravenous injection to prevent the drug from entering the systemic circulation in a short period of time. If a pregnant woman needs to be treated with drugs, she should try to use drugs in FDA classification A and B, which have less impact on the fetus, and try to avoid combined drugs, and also avoid drugs that are put into clinical time too short to reduce the uncertainty brought by drugs.
