Appropriate "pregnant" movement, away from venous thromboembolism

After pregnancy, many pregnant mothers have become the center of the family, enjoying the treatment of the stars holding the moon, clothes to reach out, food to open their mouths, and even to raise a fetus all day long, do nothing, is to eat and drink, lie down and play mobile phones.

However, such a fetus, completely inactive throughout pregnancy, will increase the possibility of venous thromboembolism (VTE) during pregnancy or puerperium, and even threaten the life of the pregnant woman.

During pregnancy, the human body is in a state of easy thrombosis

In recent years, the number of elderly pregnant women, obesity and pregnancy complications has increased, and the incidence of venous thromboembolism during pregnancy and puerperium has increased significantly. Excessive obesity, advanced age, lack of physical exercise, and long-term bed rest after surgery can cause blood stasis and increase the risk of venous thromboembolism.

Maternal due to physiological factors and lower limb venous load increased, pregnancy blood volume increased by about 20% compared with normal state, venous vasodilation, blood circulation slower, blood flow is slower, pregnancy and puerperal coagulation system hyperactivity, in this case, if the maternal activity is less, the blood will be in a hypercoagulable state, the risk of deep vein thrombosis is 4 times to 5 times that of normal people.

During pregnancy, especially in the third trimester, under the influence of hormones produced by the placenta and endocrine, a series of adaptive changes will occur in various systems in pregnant women, and pathological factors related to thrombosis, such as venous stasis, hypercoagulable state and vascular wall damage, exist at all stages of pregnancy, of which the aggravation of venous stasis is the most common risk factor. Various physiological changes during pregnancy make the body appear in a thrombotic state, and surgical stimulation increases platelet activation, aggravating the hypercoagulable state.

Vigilance for venous thromboembolism is required after caesarean section

With the liberalization of China's two-child and three-child policies, while the number of elderly pregnant women increases, the incidence of maternal acute critical illness and caesarean section also increases, resulting in an increase in the probability of pelvic and lower extremity venous thromboembolism, if not treated in time, it can lead to partial or complete loss of function of the patient's affected limb and disability, and severe cases may be complicated by pulmonary embolism, life-threatening.

The application of anesthetic drugs in caesarean section can dilate peripheral blood vessels, relax muscles, resulting in weakened squeezing of blood vessels by muscles, and weak blood flow; postoperative flatulence and traction pain of incisions can cause the body's stress response, activate the inflammatory response in the body, and a large number of inflammatory factors accumulate to invade vascular endothelial cells and form local thrombosis. In addition, pre- and early postoperative fasting before and after caesarean section, maternal blood volume reduction, hemoconcentration, higher blood clotting, slow venous return of limbs caused by preoperative or postoperative bed rest, and some pathological factors such as hypertensive diseases during pregnancy, etc., cause thrombosis to form after caesarean section. Therefore, after caesarean section, it is easy to develop venous thromboembolism, and it is necessary to be vigilant.

Exercise for pregnant women should be carried out appropriately according to the situation during pregnancy

In order to prevent the occurrence of venous thromboembolism, pregnant women should follow the doctor's advice according to the pregnancy situation, in the absence of contraindications to activities, do some exercise appropriately, such as walking, pregnant women's aerobics, swimming, yoga, simple housework, etc., not only can avoid excessive weight gain during pregnancy, blood sugar rise, macrosomia, etc., but also have great benefits for childbirth, can promote natural childbirth.

Activities as early as possible on the day after childbirth, activities based on personal comfort as the principle, step by step, gradually increased, about ten days after childbirth can do some light housework, avoid standing for a long time.

After returning to the ward after the cesarean section, the woman can massage both lower limbs and perform turning over activities with the assistance of medical staff after 6 hours. The next day, depending on the situation, you can get out of bed with the assistance of others. Now, clinically, after full evaluation, the use of barometric pressure therapy instrument to prevent venous thrombosis has a significant effect on preventing venous thrombosis.
