How many days can pituitrin be used? Pituitrin is the strongest visceral vasoconstrictor. It will reduce the blood flow of all internal organs, thus leading to a decrease in portal vein blood and a decrease in portal vein pressure. The clinical use of pituitrin is limited because of its many side effects, which are related to its powerful vasoconstriction characteristics, including ischemia of heart and peripheral organs, arrhythmia, hypertension and intestinal ischemia. Although its efficacy and safety can be significantly improved by the combination of nitrates, the side effects of combined therapy are still higher than those related to terlipressin, somatostatin or their analogues, so it can only be used continuously for up to 24 hours at the highest effective dose to minimize its side effects. Continuous intravenous infusion of pituitrin is 0.2-0.4U/min, which can be increased to 0.8U/min at most. Nitroglycerin should be given intravenously at the same time, with the initial dose of 40ug/min, which can be increased to 400ug/min at the maximum, and adjusted to maintain systolic blood pressure >: 90mmHg。
Pituitrin is a drug that promotes uterine contraction. Poor uterine contraction and vaginal bleeding can be used. It usually takes 3~5 days. It depends on personal circumstances. Proper getting out of bed after delivery is beneficial to uterine contraction and lochia discharge. Pay attention to the intake of diet. The diet is light and rich, easy to digest. Eating more high-quality protein and high-protein foods is conducive to physical recovery and eating more fresh vegetables. Pay attention to personal hygiene, and check regularly after delivery.
According to your description. Pituitrin is mainly used for postpartum hemorrhage, gastrointestinal ulcer hemorrhage and other digestive bleeding symptoms. The course of treatment of pituitrin depends on the bleeding. It is suggested that if the bleeding has stopped after oral medication. You can stop taking the medicine after 3~5 days of oral administration. Observe closely after stopping the drug.
Pituitrin is a water-soluble component extracted from the posterior pituitary of pigs and cattle, which contains oxytocin and vasopressin. Oxytocin has a selective effect on uterine smooth muscle, and its intensity depends on the dose and physiological state of uterus. For non-pregnant uterus, a small dose can enhance the rhythmic contraction of uterus. Large doses can cause uterine tension and contraction. The pregnant uterus is not sensitive in the early pregnancy, and the sensitivity gradually increases in the late pregnancy, and the effect is the strongest during delivery, and the influence on the uterus gradually weakens after delivery. The effect of this product on uterus is characterized by strong contraction of uterine body and little contraction of cervix.
What is the usage and dosage of vasopressin? It is a water-soluble component extracted from the posterior pituitary of pigs and cattle, and contains oxytocin and vasopressin (vasopressin is also called antidiuretic). Oxytocin has a selective effect on uterine smooth muscle, and its intensity depends on the dosage and physiological state of uterus. For non-pregnant uterus, small dose can strengthen the rhythmic contraction of uterus; High dose can cause tonic contraction of uterus. For pregnant uterus, it is not sensitive in the early pregnancy, but the sensitivity is gradually strengthened in the late pregnancy, and the effect is strongest in labor, and the effect on uterus after delivery is gradually reduced. The effect of this product on uterus is characterized by strong contraction on uterine body and less contraction on cervix. In addition, it can enhance the contraction of mammary smooth muscle and promote milk ejection. The antidiuretic urea contained in this product can reduce the urine volume of animals, and also has the effect of contracting capillaries and causing blood pressure to rise.
Pituitrin is not suitable for induced labor or induced labor because of its strong excitatory effect on uterus and pressor effect. If you have pallor, sweating, palpitation, chest tightness, abdominal pain, anaphylactic shock, etc. after taking the medicine, you should stop taking the medicine immediately.
Pituitrin is mostly used for hemoptysis in respiratory medicine, such as hemoptysis caused by dilated branches or tuberculosis cavity. Because it can constrict blood vessels, it can't be used in some cases, such as patients with coronary heart disease and pregnancy. The use of pituitrin is a measure taken after the expected date of delivery. This is an effective measure to avoid the baby's intrauterine hypoxia.
