Neonatal vomiting

Vomiting is one of the common symptoms in the neonatal period. It is the vomiting center in the brain that manages vomiting. Any irritation of the soft palate, pharyngeal wall, gastrointestinal tract, and certain diseases of the nervous system itself (encephalitis, meningitis, etc.) are transmitted from the nerve to the vomiting center, which is a series of complex neuroreflexive activities. The center responds, causing the esophagus, stomach, or intestines to move from bottom to top, and the diaphragm and abdomen muscles force the food in the stomach to flow out of the mouth. Neonatal digestive system anatomy and physiology makes vomiting prone in many cases, especially 3 or 4 days after birth. Because vomitus is often sprayed from the mouth and nose at the same time, it is easy to suffocate into the airway and cause suffocation and / or aspiration pneumonia. It also easily causes water, electrolyte disturbances, acid-base balance imbalance, and even death. Prolonged vomiting can also lead to malnutrition.
