A couple of days ago, the media frequently forwarded a news story about a pregnant woman who was 17 months pregnant, and the doctor said she was not allowed to give birth. The news of “Nezha’s reincarnation” and “pregnant with an elephant” spread. Various mainstream and non-mainstream media outlets forwarded the news. As an obstetrician and gynecologist, I can’t help but laugh when I see such news, you can tease the people, don’t tease me. If you’re really pregnant for 17 months, you’ll probably become a stone monkey. After pregnancy, doctors will calculate a prenatal period, if the usual regular menstruation, 28-30 days once, then the general prenatal period is from the last menstruation plus 280 days (i.e. 40 weeks) is the time of the prenatal period, if their own simple mental calculation, is to use the month -3 (or +9), the number of days +7 way to estimate the prenatal period, such as today is August 18, then the prenatal period For example, if today is August 18, then the due date should be May 25, which is not different from the one calculated by the doctor in the hospital with the computer or app, but if the menstruation is usually irregular, this calculation is very problematic. For example, if the length of the fetus is 5.5cm today, then today is 12 weeks of pregnancy and the due date is March 2, 2017. For people with inaccurate menstruation, it is often necessary to postpone the due date based on the ultrasound results. Once the due date is determined, then the child will know when the pregnancy is full term, 3 weeks backward from the due date, that is, 37 weeks is full term, the due date is more than 2 weeks, after 42 weeks is overdue, which means that in most cases we need to control the birth of the child between 37 weeks and 41 weeks and 6 days, if it is early, the child is premature, often the child will face the fetal lungs are not If it is early, the baby is born prematurely, often the child will face immature fetal lungs, easy infection, etc. If it is late, the placenta will age and the chance of fetal death in the uterus will increase, so if the due date is exceeded, it is generally necessary to start considering induction of labor after 41 weeks, but the prerequisite for induction of labor is that the due date must be accurate (this also explains the need for ultrasound examination at an early stage for people with inaccurate menstruation), otherwise it is less likely to be successful if it is early, and it is possible to The risk of inducing an immature child is increased if it is induced late. The next time you hear about 17 months of pregnancy, only those journalists and editors who don’t think twice about it as news, and irresponsibly send it out to entertain the nation, the next time you send this kind of medical-related news, you better interview a professional doctor to understand the situation behind it. From my judgment, the biggest possibility is that the patient usually irregular menstruation, several months, and then a pregnancy, but also from the last menstruation to count the pregnancy week, and then calculate their own 17 months, but the doctor certainly understand when her real due date is, although menopause may have 17 months, but may be intrauterine pregnancy is not yet full-term, it is not surprising. It’s not surprising that the time of the intrauterine pregnancy may not be full term. Everything should be taken seriously, especially by journalists, who don’t just want to get eyeballs and end up with a joke about “Nezha”.
