Does nebulization have side effects on pregnant women?

Nebulization will have certain effects on pregnant women, mainly because the drugs in the nebulizer may have certain effects on the fetus. Nebulization is widely used and has a good effect on the treatment of diseases. If you are pregnant, it is generally recommended to avoid using this method, as it will have certain side effects on both yourself and the fetus, and will cause radiation to the fetus and affect its development.

Nebulization is the use of a nebulizing device to disperse drugs (solutions or powders) into tiny droplets or particles, suspending them in the gas and allowing them to enter the respiratory tract and lungs, thereby achieving the purpose of airway cleansing, airway humidification, local treatment (antispasmodic, anti-inflammatory, expectorant) and systemic treatment. It can also be used by pregnant women. However, because some drugs can affect the health of the fetus, pregnant women must use drugs reasonably under the guidance of a doctor when doing nebulization. They must not use drugs that are prohibited for pregnant women, so as not to affect the health of the fetus.

Generally speaking, after you tell your doctor that you are pregnant, the nebulized medicine prescribed by the doctor will have no effect on the fetus. However, if a pregnant woman undergoes ultrasonic nebulization, the ultrasonic instrument will generate a lot of energy, which is different from the energy used in a B-ultrasound examination and will have an impact on the fetus. In addition, ozone is used during nebulization. It is a strong oxidant that can seriously interfere with the synthesis and division of DNA and has a clear teratogenic effect. Treatment of pregnant women may cause fetal malformations.

Body position: Pregnant women should take a sitting, semi-sitting or side-lying position during nebulization, and try to avoid lying on the back. If lying on the back is necessary, the head of the bed should be raised 30°. During treatment, you need to inhale slowly and deeply, pausing for a moment at the end of the inhalation, which will allow the droplets to be inhaled deeper.

Dosage: The nebulizer liquid for pregnant women should be freshly prepared every day. When inhaling, you must start with a small dose, and then gradually increase the dose after getting used to it, until all the liquid is inhaled. Do not use a large dose at the beginning, because a large amount of cold mist entering the airway rapidly will cause spasm of the airway smooth muscles, leading to worsening of breath holding and breathing difficulties.
