Ultrasonic examination should be "whispered" (Figure)

"Respect for children" has become the consensus of many parents and even the whole adult world However, in many people's understanding, "respect for children" begins after the birth of the child, but little attention is paid to the respect for the rights of the baby during the fetal period Professor Cai Yan, director of obstetrics at the Fourth Affiliated Hospital of Harbin Medical University, recently called for "real respect for children should start from the mother." Many pregnant women will be worried about gain and loss after pregnancy They often worry about the normal development of their baby They often go to the hospital for examination Director Cai Yan once met a pregnant woman who had five ultrasound examinations and several other single examinations in three months due to over tension What she didn't know was that this kind of blind birth examination disturbed the pregnant environment of the fetus instead Professor Cai Yan said that now four-dimensional (4D) ultrasound has been "enshrined as a treasure" by many pregnant women Generally speaking, 4D ultrasound image is a DVD image based on 3D ultrasound image and time dimension parameters Because it takes a long time to record this kind of DVD, the fetus will be exposed to ultrasound environment for a long time, and pregnant women will also feel tired, which is easy to damage the intrauterine environment "The production inspection must be carried out on the premise of necessity and science." Professor Cai Yan suggested that if there is no special situation, pregnant mothers only need to have 4-5 ultrasound examinations during the whole pregnancy In the first 6-8 weeks of pregnancy, the purpose is to investigate ectopic pregnancy (ectopic pregnancy) or abnormal pregnancy (hydatidiform mole), and understand the survival status of embryo; in the second 11-14 weeks of pregnancy, the main purpose is to check the neck transparency (NT) of fetus, and evaluate the risk of fetal chromosomal abnormality combined with the serological examination of pregnant women; in the third 18-24 weeks of pregnancy, the main purpose is to systematically check the development of fetus And screening fatal malformations, this examination is more important, the doctor should see more detailed than before; the fourth and fifth time in 32-38 weeks, the purpose is to exclude the development abnormalities that may occur in the late pregnancy, understand the umbilical cord blood flow situation, evaluate the safety of the fetus in the uterus, and provide reference for clinicians to choose the time and mode of delivery The prenatal examination must be humanized Director Cai Yan also introduced that the auditory system of the fetus around 28 weeks of gestation has developed well In the warm body of the mother, the baby can not only hear the mother's heartbeat and the sound of tissue peristalsis, but also hear some external movements, such as the voice of speech, music, car speakers However, the pleasant and harsh sounds to the baby's feelings are totally different, even if the pleasant music, too long stimulation time will become noise Therefore, the examination of obstetricians must be humanized to avoid "noise" caused by "barbaric" examination Professor Cai Yan explained that Doppler ultrasound can amplify fetal heart sound more clearly and accurately than the traditional way of listening to fetal heart with a earpiece Because many pregnant mothers like to hear their baby's heartbeat during the examination, some doctors turn on the sound volume of Doppler examination very much At this time, many pregnant women will feel the fetal movement in the body Pregnant mothers think it's a sign of baby activity, so they are overjoyed However, it is likely that this is a response to the baby's inability to withstand the noise Therefore, when doing Doppler examination, doctors should be as quiet as possible to prevent excessive sound from damaging the quiet environment of the uterus, which is also a manifestation of humanity and respect for the fetus At the same time, mothers to be must also pay attention to keep the abdomen away from noise sources.
