Precautions for standard abdominal circumference of uterine height at 36 weeks of pregnancy

We all know that each of us comes into this world by being born from our mother’s belly. Our mothers carry us for ten months and give birth to us successfully. Many people may want to know how a life is born? In fact, it takes a long process for our sperm and egg cells to combine and hatch in the mother's body. Maybe everyone is particularly interested in the standard of uterine height and abdominal circumference at 36 weeks of pregnancy. Let us learn about the relevant content of the standard of uterine height and abdominal circumference at 36 weeks of pregnancy.

Note:

1. Anti-allergic: In case of anaphylactic shock, large doses of corticosteroids should be used, usually hydrocortisone, 500 mg immediately, generally 1000-2000 mg per day, by intravenous drip. However, hormones can inhibit the function of the reticuloendothelial system, making it impossible to clear activated coagulation factors in time and aggravating DIC. Therefore, care should be taken when using them repeatedly. It is better to use this drug on the basis of heparin treatment.

2. Oxygen inhalation: Positive pressure continuous oxygen administration should be performed, at least using a mask. Nasal cannula oxygen administration is not effective. If conditions permit, a ventilator can be used. Oxygen supply can reduce pulmonary edema and improve brain and other tissue hypoxia.

3. Relieve pulmonary hypertension: Oxygen supply can only solve the alveolar oxygen pressure, but cannot solve the pulmonary blood hypoperfusion. Pulmonary hypertension must be relieved as soon as possible to fundamentally improve hypoxia and prevent acute right heart failure, peripheral circulatory failure and acute respiratory failure. Commonly used drugs are the following:

1. Aminophylline: It has the effects of relieving pulmonary vasospasm, dilating coronary arteries and promoting diuresis, as well as relieving bronchial smooth muscle spasm. The dosage is 0.25-0.5 g added to 20 ml of 10%-25% glucose solution and injected intravenously.

2. Papaverine: It has a dilating effect on coronary blood vessels, lungs and cerebral blood vessels, and is an ideal drug for relieving pulmonary hypertension. The dose is 30-60 mg added to 20 ml of 25% glucose solution and injected intravenously.

3. Atropine: It can relieve pulmonary vasospasm, inhibit bronchial secretory function and improve microcirculation. The dose is 0.5-1 mg, intravenously, once every 10-15 minutes until symptoms improve.

4. Phentolamine: Relieve pulmonary vasospasm, the dose is 20 mg added to 250 ml of 10% glucose solution and injected intravenously.

4. Anti-shock: The shock caused by amniotic fluid embolism is relatively complex and is related to multiple factors such as allergy, pulmonary, cardiogenic and DIC. Therefore, comprehensive consideration must be given when dealing with it.

1. Expanding blood volume: In shock, there is a lack of effective blood volume, and blood volume should be expanded as early as possible, but improper application can easily induce heart failure. If conditions permit, it is best to use a pulmonary artery floating catheter to measure the pulmonary capillary wedge pressure (PCWP) and replenish blood volume while monitoring the cardiac load. If it is not possible to measure PCWP, infusion can be guided by central venous pressure. Regardless of the monitoring method used, 5 ml of blood should be drawn at the same time as intubation, a blood sedimentation test should be performed, a smear should be stained to find the amniotic fluid components, and relevant DIC laboratory tests should be performed. For the choice of volume expansion fluid, dextran-40 500-1000 ml is often used initially by intravenous drip. Patients with blood loss should be supplemented with fresh blood and balanced fluid.

The above content introduces us to the standard of uterine height and abdominal circumference at 36 weeks of pregnancy, which satisfies the curiosity of many people. We know how we came into this world step by step and how we grew up step by step. We should all learn more about this knowledge so that we can realize that our life is hard-won.
