The best time to travel during pregnancy.

Modern transportation is convenient, and people often choose to travel by plane or on business at home and abroad. According to the recommendation of American College of Obstetrics and Gynecology, pregnant 18 ~ 24 weeks is the best time for pregnant mothers to travel safely. The World Health Organization (WHO) recommends that primiparas can fly before 36 weeks of pregnancy, while multiparas (who have given birth more than once) should not fly after 32 weeks of pregnancy.

Two reasons? People with complications should not take it.

The most important prerequisite for pregnant mothers to fly is "safety". The so-called safety, first of all, pregnant mothers must be in a healthy state, and there can be no complications of obstetrics, internal medicine and surgery.

Obstetric complications include placental abnormality, premature delivery or abortion history, abdominal pain, bleeding, abortion risk, pre-eclampsia, etc. Medical complications include hypertension and diabetes, especially pregnancy complicated with hypertension, which will naturally increase the risk and may lead to placental abruption; Or thrombosis, anemia, heart and lung diseases, etc. ; As long as pregnant mommy has any of the above conditions, it is not suitable for flying.

1 low humidity? There is a high possibility of premature delivery.

If you travel for a long time, the plane will be lifted to more than 9.7536 kilometers. Although the cabin pressure in the aircraft will be maintained at the altitude of 1 .8288km, it is still lower than1atm (about 0.8 atm), and some people will have a "bang" in their ears, which is caused by internal pressure imbalance. The outside temperature is mostly around -20℃ ~-30℃, and the inside will keep a constant temperature of 23℃ ~ 25℃; The humidity outside the machine is about 10%, and the humidity inside the machine is about 30% ~ 40%, which is far lower than 50% ~ 60% of the daily living environment. If air conditioning is added, the humidity will be lower.

If the humidity is less than 25%, the human body will feel dry, and then lose more water, and the blood will thicken, so it is easy to have symptoms of venous embolism. For pregnant mothers, it will increase the risk of premature delivery.

2 low pressure? fetal anoxia

If the pressure becomes thinner, the oxygen concentration in the blood will be insufficient. According to related research, when the engine room pressure is maintained at 1.8288 km, the oxygen consumption of pregnant mothers will decrease by 13% (generally only by 3%).

The oxygen partial pressure of ordinary people and healthy pregnant mothers decreases at high altitude, which will basically not cause problems and will not lead to fetal hypoxia; However, pregnant mothers with heart and lung diseases can easily lead the fetus to fall into a crisis of hypoxia, and in severe cases, it may also lead to early placental detachment.

Four directions? Choose the right voyage

If the pregnant mother wants or needs to go abroad during the pregnancy suitable for flying, it is suggested to choose the appropriate flight destination according to the following four directions.

1 Don't take too long.

Generally speaking, a voyage of more than 5 hours is called a long-distance flight. Try to reduce the number of long-distance trips during pregnancy. If it is very necessary or desirable, it is best to fly within 5 hours. In addition, the altitude of short-distance flight is lower than that of long-distance flight, the flight time is shorter, and the change of humidity and air pressure is smaller, which will reduce the probability of discomfort of pregnant mothers.

Two countries that have developed tourist attractions.

Pregnant mothers are inconvenient to move, and it is inevitable that there will be occasional temporary situations. If you travel in a country with developed tourist attractions, besides clear regional planning, convenient transportation and good environmental sanitation, it is easier to seek convenient help through the country's perfect tourist facilities and management system.

3 The temperature drop range is too different.

As for areas that are too hot (such as near the equator in Africa) and too cold (such as Alaska in North America), it is not recommended to go because it may make it difficult for pregnant mothers to adapt.

Is it an epidemic area?

More importantly, if it coincides with the epidemic, such as SARS and cholera, it is even more impossible to go, so as not to hurt pregnant mothers and fetuses.

Pay more attention to the plane? Relieve travel discomfort

When pregnant mothers get on the plane, during the flight for several hours, it is suggested to pay more attention to the following matters, which will help alleviate the possible discomfort.
