Cough in pregnant women in late pregnancy can be treated with nebulized inhalation. Nebulized inhalation is a local administration, short in duration and with relatively few side effects, which can significantly moisten the airway and help improve cough-induced bronchitis and dyspnea. Antibiotics are generally not actively used for nebulizer treatment, and hormonal drugs can be chosen for nebulizer inhalation, as many of them may lead to the possibility of fetal malformation and miscarriage. Nebulized inhalation for pregnant women in the clinic must be performed under the guidance of a physician, and nebulized treatment should be stopped immediately once symptoms such as pallor and lack of itching occur.
