1, the baby often choking causes The baby’s normal breathing movement, sucking action, swallowing movement of the three coordinated, will not occur choking, if any of the three action is not normal, mismatch will occur choking, milk easy to inhale into the lungs, resulting in milk aspiration pneumonia. The most common causes of choking are: the child’s hunger is obvious, too fast to eat milk, swallowing more air; mother’s milk is too much, more than the baby’s swallowing speed; and then immediately after eating the milk to lie down, easy to cause the baby’s stomach milk reflux and cause choking. If your baby chokes repeatedly, you need to look for the reasons from the above three aspects of breathing, sucking and swallowing. Preterm babies or bronchopulmonary dysplasia, or repeated pneumonia in children due to the lungs of the poor function of the whistle easy to choke, in addition to preterm babies or bronchopulmonary dysplasia in children are most likely to occur in the stomach content of the reflux of inhalation; in the brain injury, cerebral dysplasia caused by spherical palsy in children with dysphagia, cleft lip, cleft palate in children with dysfunction of the sucking and swallowing; oesophageal atresia or tracheo-esophageal fistula in children are prone to choking, but also easy to occur. The first thing you need to do is to get rid of the milk aspiration pneumonia. 2, how to judge the milk aspiration pneumonia ① after breastfeeding suddenly appeared to whistle stop, bruises or choking cough, airway milk sucked out; such as swallowing dysfunction of the baby milk from the nasal cavity, at the same time coughing, sometimes bruises; esophageal blind end of the baby, because the milk stays in the pharynx, whistle will be whistling; esophageal trachea fistula choking, shortness of breath and bruising; esophageal incomplete people Easy to spill milk. ②Signs and symptoms of the respiratory system: the severity is related to the amount and frequency of inhalation. If the amount of inhalation is small or occasional, bronchitis is the main symptom, and the symptoms include sudden cough, wheezing, shortness of breath, whooping distress, and triple concave sign. Pneumonia occurs when the amount of inhalation is large, a large amount of inhalation, can cause asphyxia, the whistle stops, to the whistle to recover, the emergence of obvious shortness of breath, pulmonary rales, and the signs and symptoms last more than 72 hours; the severity of the inhalation of the amount of and the number of times related to. Before inhalation, due to local irritation, the protective closure of the epiglottis is caused, and the child has apnea of the whistle, which is clinically manifested as symptoms of obstruction of the airway; after inhalation, there is a whistle embarrassment and the corresponding lung infiltration foci on the X-ray, which is difficult to distinguish the clinical manifestations from the infectious pneumonia. Due to pulmonary edema, hemorrhage, etc. so that the lung compliance is reduced, can also be secondary to bacterial infection in breast milk aspiration pneumonia. Long-term multiple inhalation of interstitial pneumonia, and finally lead to pulmonary fibrosis or complication of bronchiectasis. 3, breast milk aspiration pneumonia treatment ① clean up the airway: immediately with a suction tube or tracheal intubation suction, keep the airway open. ②Improve ventilation and oxygen supply: choose the way of oxygen suction according to the degree of hypoxia. x-ray chest film to monitor lung lesions, pay attention to whether there is complication of pneumothorax or mediastinal emphysema. ③Preventing and controlling infection: use broad-spectrum antibiotics, and take tracheal secretions for bacterial culture and drug sensitivity test. Symptomatic treatment: ensure nutrition, mild cases can be breastfed a small number of times, severe cases can not be fed need intravenous fluids, if necessary, give parenteral nutrition. Timely treatment of various complications.
