Amniotic fluid index balance method at 33 weeks of pregnancy

We all know that it is very difficult for every pregnant mother to be pregnant for ten months, and our mothers have to endure the physical discomfort, so we should take better care of our pregnant mothers. Many people know very little about the standard amniotic fluid index at 33 weeks of pregnancy. We must know more about this aspect, so that it can bring greater help to the health of our pregnant mothers. Many people have overlooked the issue of the 33-week amniotic fluid index standard. Let us learn about the 33-week amniotic fluid index standard together!

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 precautions for the amniotic fluid index at 33 weeks of pregnancy. I believe that everyone now has a clearer understanding of the content of this cake. We should try to learn more about this aspect to help our pregnant mothers give birth to our babies better.
