Pneumonia caused by meconium aspiration in newborns is a critical condition, and the length of hospitalization depends on the severity of the condition, usually 1-3 weeks. The pneumonia caused by aspiration of meconium in newborns is usually due to asphyxia and lack of oxygen during intrauterine or delivery, resulting in the relaxation of the anal dilator muscle and the discharge of a large amount of meconium, which can cause pneumonia and pulmonary edema when the fetus inhales amniotic fluid mixed with meconium. Most children need assisted breathing or mechanical ventilation to keep the airway open, as well as antibiotics for anti-infection treatment. However, if the baby’s condition does not cause severe lack of oxygen to the brain tissue, there are usually no sequelae after treatment. However, if the condition is more serious, there is a risk of pulmonary hemorrhage and cerebral hypoxia damage, which may even lead to death. After the baby is discharged from the hospital, parents need to pay attention to his or her condition and be promptly admitted to the hospital in case of abnormal performance.
