If a newborn baby is drowsy, does not wake up and does not eat milk, it is generally considered to be a sign of critical condition. Go to the hospital in time to find out the reason why the baby is drowsy and does not eat milk and take appropriate treatment. If the baby has a history of asphyxia and hypoxia at birth, it may be hypoxic-ischemic encephalopathy or intracranial hemorrhage, and if it is accompanied by convulsions and seizures, it is best to have a cranial CT examination to help diagnose the problem if necessary. If the baby is spitting up, choking or has a cold, or if someone in the family has a cold, and there is also shortness of breath and frothing at the corners of the mouth, it may be neonatal pneumonia, which can easily be combined with heart failure and respiratory failure. If the baby is also jaundiced, has skin infection or umbilical cord infection, pay attention to neonatal sepsis, neonatal encephalitis and meningitis. Strengthen the care of the skin and umbilical cord. Saline or sodium bicarbonate can be used for oral care; disinfect the umbilicus with iodophor or alcohol two to three times a day to keep the umbilicus dry, hygienic and clean, and umbilicitis can be treated with antibiotics at the same time. So during the newborn period, you must closely observe the baby’s spirit to eat milk and other conditions, take the correct feeding method to avoid spitting up or choking, and you must pay attention to the umbilical cord and oral care.
