The 33rd week of the 40th week of pregnancy: delivery skills need to be practiced

In order to reduce the tension of childbirth, expectant mothers can learn some childbirth skills from now on, which is very helpful for the smooth delivery

Physiological changes of expectant mothers

At 33 weeks, if you are a primipara, the baby's head has fallen into the pelvis and pressed tightly on the cervix 。 For multiparas, the time for the fetus to enter the pelvis will be later. At this time, the puerpera will have edema in their hands, feet, legs, etc., so pay attention to the water intake. For pregnant women with severe edema, they should go to the hospital to see a doctor in time.

Fetal development

The 33 week old fetus is about 48cm long and weighs about 2200g 。 Foetal Respiratory system and digestive system The development is close to maturity. The 33 week old fetus should pay attention to the position of the head. Whether the fetal position is normal or not is directly related to whether you can deliver normally. The baby's skull is very soft now, and there is a gap between each skull, which is to prepare for the baby's head to pass through the vagina smoothly during childbirth. But the bones in other parts of the baby's body have become very strong, and the baby's skin is no longer red and wrinkled.

Delivery exercise

Every mother should know something about childbirth and relax her nervous system so as not to lose her footing in childbirth.

Breathing Skills Practice

·Breathing in the first stage of labor Abdominal breathing

Abdominal breathing can strengthen abdominal muscles, which can ease pain when labor pains occur in the first stage of delivery. Specific method: supine. The legs are easily separated and the knees are slightly bent. Open your thumbs and put the other four fingers together on your lower abdomen. The thumbs of both hands are about directly below the navel. Inhale deeply to make the lower abdomen swell. When the abdomen expands to the maximum, exhale slowly to restore the lower abdomen. Such repeated "expansion" and "exhalation".

·Breathing chest breathing in the second stage of delivery

When the uterine contractions are approaching, use chest breathing method to suck 80% of the breath into the chest. When the uterine contractions are most severe, hold your breath for 3-4 seconds, exert yourself towards the anus, and exhale the inhaled breath while exerting yourself.

Short Breathing: At the end of the second stage of labor, relax the abdomen to expose the fetal head slowly.

Effort practice

·Stage I: Breathe evenly without exerting force

At this stage, we should consciously exercise abdominal deep breathing. During uterine contraction, inhale deeply, inhale deeply and slowly, and exhale slowly; During the interval of uterine contraction, it is best to close your eyes and rest to refresh yourself.

·Stage II: Try your best and hold your breath

After the opening of the uterine orifice is complete, when the uterine contraction begins, the expectant mother in labor should flex her legs and separate them, grasp the handle with both hands, and force downward like defecation. The longer the time, the better, to increase abdominal pressure and promote the delivery of the fetus. When the contractions are intermittent, fully relax and rest, and choose to exert again when the contractions are next time.

·Stage 3: Try your best again

At this time, you can also use your full strength according to the second stage of breath holding method to speed up the delivery of placenta and reduce bleeding.

Delivery exercise

Experts remind: avoid 3 wrong methods of force

Error 1: Groan or shout loudly

Not only can this not alleviate the pain, but the opposite may cause excessive ventilation, which may lead to maternal hypoxia, fetal brain, umbilical cord, uterus, placenta circulation blood volume reduction, secondary alkalism, etc; It will also consume too much physical strength, making it powerless to use when it really needs to exert.

Error 2: Hold your breath and exert yourself in the first stage of labor

This will consume physical strength prematurely, and holding your breath for a long time will easily lead to respiratory acidosis.

Error 3: Hold your breath downward when the fetal head is about to be delivered

This may cause the fetus to deliver too quickly, resulting in perineum laceration.
