Patient Question:Disease:Neonatal wet lung Description:Newborn 37+1 days caesarean section, just born, shortness of breath, an average of 66 times per minute, then transferred to the neonatal unit in the incubator, hope to provide help:I want to know how this neonatal wet lung is produced? How long does it take to heal in the incubator? The first hospital of Xiamen University, Department of Pediatrics, Liu Dengli replied: The fetal lung is made of lung fluid, under normal circumstances, vaginal delivery, due to pain stress, lung fluid secretion is reduced, absorption increased, due to the birth canal extrusion, part of the lung fluid through the mouth and nose out of the body, so the normal vaginal delivery of a full-term child, lung fluid is basically expelled after birth. In children delivered by cesarean section, especially those delivered by elective cesarean section, the lung fluid is less expelled, and the alveoli are still filled with lung fluid after birth, which affects gas exchange, so respiratory distress occurs and requires oxygen therapy, and the symptoms usually disappear within 72 hours, but severe cases require tracheal intubation and mechanical ventilation. At present, cesarean delivery is not advocated unless clinically indicated, and elective cesarean delivery is opposed. A full-term baby does not necessarily need to be placed in an incubator. As for when the child can be discharged from the hospital, it depends on all aspects of the child’s condition, such as stable breathing, sufficient milk, no other discomfort, then you can consider discharge.
