Antenatal instruction with information transmission method, say it in another way is to create a favourable internal and external environment for fetal during pregnancy.
1, to avoid the seven emotions. Famous medical Wan Zongzhai in the Ming dynasty in antenatal instruction theory States that: \"cure the seven emotions: joy, anger, worry, thinking, sadness, and fear, and surprise.\" This \"XI\" means, in his view, \"the sad and gas\".
Scientific studies prove that pregnant women when the agitation, increased body movements of the fetus, fetal movement times 3~10 times greater than usual. Such as fetal long-term concern, the candle, often lighter than General infant birth weight of 0.5~1 kg. Pregnant women and people argue, family discord, extreme sorrow, emotional depression, her husband has a bad temper, discord, interpersonal tensions such as the relationship between mother-in-law and daughter-in-law, infants often have different levels of digestive dysfunction after birth, vomiting, weight loss, dehydration, restless, love cry.
Bad mental state of pregnant women caused by the stimulation to the baby causing abnormal infant behavior character. Especially of pregnant women late sudden change in mental state makes Taegu brain affected the brain thus causing increased secretion of adrenal Medullary hormones in the body. Adrenal Medulla and the whole body of human sympathetic norepinephrine secretion, radical changes in the environment, of the sympathetic nervous system activity has increased significantly. Both while increased of results makes blood within to methyl adrenaline by usually of 30 µg/100 ml of concentration increased to original no of 100 times times, heart rate increased fast, makes each heart beats bleeding volume reduced, placenta for blood volume also therefore reduced and makes fetal hypoxia, to methyl adrenaline makes smooth muscle contraction, further makes vascular contraction and the uterine contraction, increased has hypoxia, can makes fetal brain development blocked. Therefore important aim must be to enable pregnant women to antenatal instruction state of spirit is always relaxed and enjoyable.
2, rational nutrition. Important that pregnant women must maintain a nutritional balance, which is the basis of fetal growth and development of health materials.
