How to treat pregnancy induced hypertension correctly? Pregnancy induced hypertension is obviously different from primary hypertension, secondary hypertension and hypertension of other diseases, which is closely related to serious maternal and fetal complications. Therefore, active treatment of gestational hypertension is very important for the safety of mother and child. However, because some drugs for the treatment of hypertension will have a certain impact on the fetus, so patients with pregnancy induced hypertension must be carefully selected.
&Propranolol, a beta; - receptor antagonist, is suitable for patients with pregnancy induced hypertension complicated with sinus and supraventricular tachycardia. In recent years, it has been found that the drug is associated with fetal distress, low birth weight and increased perinatal mortality, so it is no longer recommended for the treatment of pregnancy induced hypertension.
&The more commonly used alpha; - adrenergic antagonist is prazosin, which can not only reduce cardiac preload, but also reduce resistance vascular afterload. However, due to less accumulation in clinical application, it should be used with caution. Angiotensin converting enzyme inhibitors include captopril, enalapril, benazepril, etc. Because this kind of medicine has damage to the fetus, it should be banned in pregnant women. The new second generation of angiotensin converting enzyme inhibitor, tadopril, has good antihypertensive effect and no adverse effect on fetus, but whether it can be used in the treatment of pregnancy induced hypertension needs further exploration. In recent years, diuretics are rarely used as antihypertensive drugs during pregnancy. The main reason is that diuretics can reduce maternal blood volume and often have adverse perinatal outcomes, which should be paid attention to. Methyldopa is a commonly used antihypertensive drug during pregnancy, and it is also the only drug with long-term follow-up to childhood and proved to be safe. The method of use is oral administration of 250 mg three times a day.
Α, & beta; receptor blocker verapamil does not affect the uteroplacental circulation, has been widely used in the treatment of pregnancy induced hypertension.
The vasodilator hydralazine has obvious effect in reducing diastolic blood pressure, and does not affect the uteroplacental circulation, and has no adverse effect on the fetus. General advocate small dose (5 mg) intermittent intravenous injection, injection time is 1 ~ 2 minutes. Phentolamine can dilate blood vessels and reduce blood pressure in more than 60% of patients with hypertension.
The effect of calcium antagonists on blood pressure was mild, and cardiac output was not decreased. Nifedipine is commonly used 4-6 times a day, 10 mg each time. Nicardipine can also be used. In recent years, researchers at home and abroad have found that nimodipine is not only effective in the treatment of pregnancy induced hypertension, but also simple and safe.
Medication for pregnancy induced hypertension: the above medication for patients with pregnancy induced hypertension need to pay attention to the problems were introduced, hope to help the treatment of patients with pregnancy induced hypertension, at the same time need to pay attention to many problems, only pay more attention to ensure the safety of mother and child.
After reading the above content, we should have some understanding of how to use drugs correctly in the treatment of pregnancy induced hypertension. How to use drugs correctly in the treatment of pregnancy induced hypertension? Today we will introduce here. More topics about the treatment and health care of hypertension will continue to be introduced in the following articles. Welcome to check. Wish you a happy life!
