Oxytocin also known as
Oxytocin Acetate is a pituitary neurohormone, is commonly referred to as "birth needle" [1], the supraoptic nucleus and paraventricular nucleus of the giant cell manufactured by the hypothalamic-pituitary axis transported to the nerve fibers to the posterior pituitary secretion, and then released into the blood. Mainly used in clinical birth abortion, postpartum bleeding and shortened third stage of labor. Besides a wide range of physiological functions, especially the role of the central nervous system.
Oxytocin is a hormone produced in the brain, both men and women. In women, it can cause uterine contractions during childbirth and stimulate milk secretion, and through maternal affection between mother and child to establish contact. In addition, it also reduces the human body such as stress hormone corticosterone levels, lower blood pressure.
Oxytocin stimulate the secretion of breast and uterine contraction dual role to stimulate breast-based, its physiological role and regulation of secretion described below.
Oxytocin is a close relationship between people's origins, the reason why people are eager to embrace love kissing precisely because oxytocin at work. Oxytocin levels rise when the body, it will subsequently be able to release a lot of stress relief, anti-aging hormone, better promote cell regeneration.
Effects on the fetus: oxytocin can be selectively excited uterine smooth muscle, causing contraction of the uterus, is a strong uterine contractions agent, mainly used for oxytocin, induction of labor and the prevention of postpartum hemorrhage. Intravenous infusion of oxytocin effect occurs 1 minute, so the speed can be adjusted to control the dose infusion, thereby controlling the intensity of uterine contractions. In childbirth if they can properly use, you can play a good induction or strengthen the role of uterine contractions, also known as birth role in the clinical application is extremely broad. But the application of oxytocin, it must be strictly medication methods, including the route of administration, medication velocity and concentration, with or without medication contraindications psychosis.
Oxytocin drug itself is not much impact on the fetus, but if oxytocin infusion rate is too fast, too much administration, may cause tonic or spasmodic contraction of the uterus, due to continued strong contraction of the uterus but not diastolic or diastolic very short time because of the birth canal stenosis or fetus is too large, malposition, etc., hinder the fetus, and the result caused by the lower uterine segment thinner and eventually rupture, causing bleeding pregnant women, fetal hypoxia. Or as a result of the above cause strong uterine contractions, childbirth without too much resistance when the fetus was delivered quickly, the entire production process is not more than three hours, called radical production. This will disinfect because of too late to protect the perineum, resulting in postpartum infection, birth canal laceration, neonatal fall injuries and other consequences. And if the contractions of long duration, intermittent short or without intermittent, affecting placental blood circulation, can easily cause acute fetal hypoxia, causing stillbirth or neonatal asphyxia
