  • Don't move
  • I'm fine both physically and mentally

Is written[5]..In addition, although there were obstetrician doctors, there were few pregnant women who were too embarrassed to entrust themselves to the doctors because they were all men.Therefore, a guidance book was published so that a midwife alone could deliver safely.[6]..Also as something related to childbirth

There is.And when I gave birth, I was sitting down.And after giving birth, I had to spend seven days insomnia while sitting (because I was afraid of losing consciousness and dying) because of the myth that "blood should not be on my head".[8].

Biological aspects

Birth is from the mother for the childPhysiologyIt means becoming an independent entity.In the past, the mother supplied nutrition through the placenta, depended on the mother to dispose of the excrement, and exchanged gases such as oxygen and carbon dioxide through the placenta.The first thing a child has to do islungInhalation of outside air to.Birth is said to have the meaning of promoting this activity.

Also, fetal red blood cells for receiving oxygen from blood with low oxygen partial pressure in the mother's womb are normal within a few days.Red blood cellIs replaced with.At that time, with the decomposition of red blood cellsjaundiceSymptoms appear.

Human birth

Birth method

Vaginal delivery
The case of being born through the vagina of the mother (mother) is called vaginal delivery.Before the introduction of the technique of cesarean section, all deliveries were vaginal deliveries (transvaginal natural deliveries).childbirthreference).
Planned delivery
Due to the condition of the mother and child, or the hospital's circumstances (for example, the delivery room is too crowded, the obstetrician's manpower is insufficient, etc.), do not wait for labor to come naturally.Labor promoterVaginal delivery may be performed systematically using.It is necessary to attach a delivery monitoring device and pay sufficient attention so that the accelerator is not too effective and does not harm the mother and child.
Natural delivery
1933/In the delivery method devised by a British obstetrician, "Birth is originally a physiological phenomenon, and there is no pain other than physical pain in the uterus and birth canal."不安 緊張Invited and unnecessarypainBased on the idea that it may induce dystocia, we will adopt a method (lead method) to relieve the pain during delivery by letting the mother acquire knowledge about childbirth from the time of pregnancy and remove anxiety.[12]
Caesarean section
With the development of obstetricsCaesarean sectionIt is also possible to deliver by.Delivery at high risk in spontaneous delivery, such as breech birth, cephalopelvic disproportion, placental abruption of the placenta, etc.Placenta previaCaesarean section is applied in such cases.Once delivered by Caesarean section, another Caesarean section is recommended to avoid the risk of uterine rupture due to labor (uterine contractions).However, depending on the situation of the mother and baby, "Vaginal Birth After Cesarean" (VBAC) may be possible.

Labor pain

Labor pain is a regular contraction of the uterus that repeats before giving birth.Also, the pain that the mother feels at that time.Initially, the intervals are long, such as "getting hungry" and "hardening", but as the childbirth progresses, the intervals become shorter, the degree of contraction becomes tighter, and "pain" is recognized.

At the strongest stage, it is commonly described as "the shoji screen is invisible", and pregnant women may panic.There are large individual differences in how they feel.AlsoLamaze method(Lamaze Technique), Etc., it is possible to lighten the feeling to some extent if both mental and physical preparations are made.

If you wish to deliver without feeling any pain, you may choose "painless delivery" with "epidural anesthesia", but not all cases can achieve complete pain relief.


DeliveryPregnant womanIt is a life-threatening act for us.With the development of perinatal medicine, the risk has been significantly reduced,Perinatal mortality rateHas declined significantly in Japan. Japan's perinatal mortality rate in 2007 was 1,000 for every 4.7 live births, the lowest in the world, but it is stillPreeclampsia,Placenta previa,Placenta accreta,Umbilical cordEntrainment, heavy bleeding,HELLP syndrome, (abortion,stillbirth・ ,,AbortionThe risk of the loss of the newborn surrounding childbirth) has not disappeared.

Postpartum bleedingIs the number one cause of maternal death worldwide, most of which occurs in developing countries such as Africa.[13]..Most of the causes of bleeding are uterine two-handed compression (put your hand in the vagina, place your other hand on your abdomen, and press with both hands to pinch the uterus) to directly compress the bleeding point. ,OxytocinIf bleeding cannot be controlled by administration of drugs such asballoon((English edition) Is placed and hemostasis is attempted by compression from the uterus.[13][14].

Birth place

Childbirth at home

It is not impossible to give birth at home if both the pregnant woman and the fetus are doing well, but at present, we cannot find a "midwife" who manages the birth at home.In addition, if there is a high risk of preeclampsia, breech birth, twins, etc. in either mother or baby, hospital delivery is recommended.Home delivery is a high risk, and a medical journal states that "home delivery has three times the neonatal mortality rate compared to hospital and other medical interventions."LancetHas been announced in[15].

Childbirth at a maternity home

MidwiferyIn, the midwife or the midwife who goes to the birthing place such as the home manages the birth.Only low-risk pregnant women.If your condition is getting worse, you need to contact your obstetrician.However, unlike hospitals, midwives who cannot apply advanced medical techniques cannot perform treatments that require urgency on a minute-by-minute basis, and the risk of disability that leaves sequelae for a lifetime is high.

Childbirth at the hospital

In Japan, more than 90% of the people gave birth at home before World War II and during the postwar turmoil, but after the recovery period from the war damage and the high growth period, the number of births at hospitals increased and the number of births increased. By the end of the term, more than 90% of the population began to give birth in hospitals.[16].

Since the 1950s, when the reconstruction from the war disaster began, the number of births in hospitals has increased due to the improvement of medicine and medical technology, economic development, government income, social security expenditure, medical expenses and public expenditure on medical expenses. By the end of the high-growth period, more than 90% of the people gave birth in hospitals, and now 99% of the people give birth in hospitals.[16].. as a result,Maternal mortality rate[17][18],Perinatal mortality rate[19][20][21],Neonatal mortality[22]Has decreased with the progress of the times and has reached the lowest value in history.

There are differences in economic and medical development stages in each country, region, income level, and the world as a whole, and there are differences in maternal mortality, perinatal mortality, and neonatal mortality. Due to the improvement of medicine and medical technology, economic development, government income, social security expenditure, medical expenses and the increase in public expenditure of medical expenses, all of them have decreased with the progress of the times and reached the lowest value in history.[23][24].

CurrentPrenatal diagnosisAnd artificial pregnancy techniques are prohibited for the purpose of separating men and women.HoweverPeople's Republic of China-IndiaEtc.AsiaIn the areaNewborn OfGender ratioIs extremely inclined to men, so men and women are separated.
